[U-Boot] [PATCH] designware_i2c: Enhance DesignWare I2C driver address support
by Chin Liang See 15 Jan '14

15 Jan '14

Enhance the DesignWare I2C driver to support address length more than 1 byte. This enhancement is required as some I2C slave device such as EEPROM chip might have 16 bit address byte.

[U-Boot] [PATCH v7 01/17] sf: Add extended read commands support
by Jagannadha Sutradharudu Teki 15 Jan '14

15 Jan '14

Current sf uses FAST_READ command, this patch adds support to use the different/extended read command. This implementation will determine the fastest command by taking the supported commands from the flash and the controller, controller is always been a priority.

[U-Boot] [PATCH v4 0/37] Switch over to real Kbuild
by Masahiro Yamada 15 Jan '14

15 Jan '14

We switched to Kbuild style makefiles at v2014.01-rc1 release. With that modification, we can write makefiles simpler. But it is NOT real Kbuild. We need more progress. As the next step, this series imports (+ adjusts) build scripts from Linux Kernel under scripts/ directory. By applying this series, we can get more advantages: - short log - perfect dependency tracking - preparation to the next step, Kconfig - other things... Kbuild without Kconfig ---------------------- First of all, to make things clearer, let me explain the difference between "Kbuild" and "Kconfig". They are, I think, sometimes confusing. Kbuild - build system used for Linux Kernel. Some features of Kbuild are: (a) We can describe makefiles simply. Just add objects to "obj-y" like this: obj-$(CONFIG_FOO) += foo.o (b) We can describe directory descending nicely. Add directories with a slash to "obj-y" like this: obj-$(CONFIG_BAR) += bar/ (c) Short log like follows: CC common/foo.o CC common/bar.o LD common/built-in.o (d) Perfect dependency tracking I think this is the biggest advantage. To be honest, the dependency tracing of U-Boot build system was not reliable. Kconfig - A tool to manage CONFIG macros. We can handle the dependency among CONFIG macros. Kconfig allows us to modify CONFIG settings easily by "make config". GUI interface are also available by "make menuconfig" All defined CONFIG macros are stored into ".config" file I think most of U-boot developers are already familiar with above. (In most cases, they are Linux Kernel developers too.) I definitely want to port both of these, but I want to do them separately: Kbuild first. (If we do Kbuild and Kconfig at the same time, it might be messed up.) So, I want to do "Kbuild without Kconfig" in this series. The conventional tool (mkconfig + boards.cfg file) is used for board configuration. Prerequisite ------------ You need to apply the followings beforehand to use this series. [1] sandbox: Use system headers first for sandbox's os.c in a different way http://patchwork.ozlabs.org/patch/294233/ How to Build ? -------------- We can build the same as before. Do board configuraton first and then run "make". $ make omap4_panda_config Configuring for omap4_panda board... $ make CROSS_COMPILE=arm-linux-gnueabi- GEN include/autoconf.mk.dep GEN include/autoconf.mk CC lib/asm-offsets.s GEN include/generated/generic-asm-offsets.h CC arch/arm/cpu/armv7/omap4/asm-offsets.s GEN include/generated/asm-offsets.h HOSTCC scripts/basic/fixdep ... You will find a difference at a glance, short log If you need detail log message, please add "V=1". (You can also use "V=2") Please note we can no longer use $ make omap4_panda CROSS_COMPILE=arm-linux-gnueabi- to do board configuration and "make" at the same time. Instead, we can use Kbuild-ish way for that purpose: $ make omap4_panda_config all CROSS_COMPILE=arm-linux-gnuabi- This series keeps the other features: - Support out-of-tree build You can use "O=<dir_name>" like this $ mkdir build_dir $ make omap4_panda_config all O=build_dir CROSS_COMPILE=arm-linux-gnueabi- - Works with parallel make option Add "-j" option for this. Compiling will get faster. - Of cource, SPL, TPL build are supported (nand_spl also works. But "nand_spl" is obsolete and we should switch to "spl". Until when should we continue to maintain nand_spl?) - Breaks no boards (except some boards which are already broken) I built all target boards to prove correctness of this series at least for compile test. My Next Plan ------------ - Import Kconfig Use "make config", "make menuconfig", "make defconfig", etc. in U-Boot. - More refactoring Some parts of makefiles are still dirty. I want to refactor more makefiles in follow-up patches. - Use "obj-m" for standalone program?? Loadable module?? I have not deceided about this yet. Note ---- - I marked dirty parts with "FIX ME". In some board-specific config.mk files. # FIX ME ifneq ($(filter lib lib/lzma lib/zlib, $(obj)),) ccflags-y := -O2 endif In the top Makefile # FIX ME cpp_flags := $(KBUILD_CPPFLAGS) $(CPPFLAGS) $(UBOOTINCLUDE) $(NOSTDINC_FLAGS) c_flags := $(KBUILD_CFLAGS) $(cpp_flags) I will re-write them more nicely after other parts are prepared. Changes for v4: - Add a new patch at the tail: 37/37 "kbuild: Do not generate .*.su files at the top directory" - Change "checkstack" target to Kbuild style - Move the line where U_BOOT_VERSION is defined Changes for v3: - Rebase on the current u-boot/master - Add a new patch at the tail: 36/36 "board: sandburst: delete FORCEBUILD" Changes for v2: - At version 1, nand_spl boards got broken at 12 and fixed at 14. Fix this problem - At version 1, sandbox got broken at 17 and fixed at 21. Fix this problem - Add a new patch at the tail: 35/35 "Kbuild: chech clean source and generate Makefile for out-of-tree build" - Rebase on v2014.01-rc2 tag Changes in v4: - Change a little checkstack target: Use $(src) rather than $(srctree) where Linux Kernel does so. - Move the line where U_BOOT_VERSION is defined - Change checkstack target - Newly added Changes in v3: - Rebase on the current u-boot/master - Use "all:" instead of "__build:" in nand_spl Makefiles - Newly added Changes in v2: - Do not double "*~" - Ignore more patterns - Rebase on v2014.01-rc2 tag - Do not use bash-dependent clean rules: For example, rm -f $(obj)tools/env/{fw_printenv,fw_setenv} should be converted to rm -f $(addprefix $(obj)tools/env/, fw_printenv fw_setenv) - Add more comments in commit log - Rebase on v2014.01-rc2 tag - At version 1, nand_spl boards got broken by this commit (and fixed again in the lator commit.) Fix this problem - Rebase on v2014.01-rc2 tag - At version 1, sandbox got broken by this commit (and fixed again in the lator commit.) Fix this problem - Change a little MAKEALL Do not add "O=<dir>" if objtree is the same as srctree. This will be helpful at 35/35. - Rebase on v2014.01-rc2 tag - Omit "*.depend*" from .gitignore - Rebase on v2014.01-rc2 tag - Rebase on v2014.01-rc2 tag - Newly added Masahiro Yamada (37): .gitignore:

[U-Boot] [PATCH v15 00/10] arm64 patch
by fenghua＠phytium.com.cn 15 Jan '14

15 Jan '14

From: David Feng <fenghua(a)phytium.com.cn> Changes for v15: - modify boot process, u-boot will run at the highest exception level until it prepare jump to OS. - Fix a few bugs in cache.S.These bug is reported by York Sun <yorksun(a)freescale.com> and Scott Wood <scottwood(a)freescale.com>. - when booting, slaves will wait on WFI, master wakeup slaves by SGI interrupt. - add generic_timer.c to utilize the newest timer architecture. - add gic.S to support gic initialization and interrupt operations, currently only support GICv2. Changes for v14: - Merge rela relocation patches from Scott Wood <scottwood(a)freescale.com>. - Remove all CONFIG_NEED_MANUAL_RELOC and other fixups due to manual relocation. With rela relocation patches them are not needed. - Fix the bug of MEMORY_ATTRIBUTES definition due to assembler. That need put brackets around (MT_NORMAL*8). Otherwise the result is wrong.This bug is reported by York Sun <yorksun(a)freescale.com>. - -msoft-float is not supported by aarch64-gcc, make a test though $(call cc-option,-msoft-float). - Adjust the virtual address space to 42 bits. - Filter armv8 boards from LIST_arm in MAKEALL. - remove gpio.h in asm/arch-armv8/ and move mmu.h to asm/armv8/ directory. - remove vexpress64.dts from this patch, it could be accessed from linux kernel. Changes for v13: - fix the bug of board_r.c and arm/lib/board.c due to CONFIG_NEED_MANUAL_RELOC. adjust initr_serial() in board_r.c to the first entry of init_sequence_r[] and relocate serial_initialize() in arm/lib/board.c, routines of serial_device should be relocated firstly by serial_initialize(), so that printf access the correct puts function, otherwise uninitialized serial_current will be selected as the output device. - fix the bug of dcache_enable(). after mmu_setup the sctrl register value should be fetched again because it has been modifed by mmu_seup() function. This bug is reported by York Sun <yorksun(a)freescale.com>. - add macro branch_if_slave to macro.h, it choose processor with all zero affinity value as the master and is used in start.S. Changes for v12: - custom the patches to new format boards.cfg. Changes for v11: - Replace CONFIG_ARMV8 with CONFIG_ARM64. Currently, it's hard to distinguish what is armv8 specific and what is aarch64 specific, so we use CONFIG_ARM64 only, no CONFIG_ARMV8 used. - rename README.armv8 with README.arm64 and make some modification. Changes for v10: - add weak definition to include/linux/linkage.h and make setup_el2/setup_el3/lowlevel_init weak routines, so them can be easily overridden by processor specific code. - modify s-o-f of 0002-board-support-of-vexpress_aemv8a which use wrong mail address of Bhupesh Sharma. Changes for v9: - add Signed-off-by information to patch "board support of vexpress_aemv8a" which SMC91111 support is integrated from Sharma Bhupesh's patch. - adjust pt_regs struct and add exception state preservation in exception.S. Changes for v8: - Integrate SMC91111 patch of sharma bhupesh. - remove v8_outer_cache* which is not need currently. - Change license tag. - Mov crt0.S/relocate.S/interrupts.c to arm/lib and rename them with _64 suffix. - Make el3/el2 initializing process of start.S as two separate routines. It could be easier to be replaced with processor specific codes. - Remove exception stack save and restore routine, it is unnecessary now. - simplify __weak function declaration. Changes for v7: - Check the patches with checkpatch.pl and get rid of almost all warnings. There are a few warnings still, but I think it should be that. - change printf format in cmd_pxe.c, use %zd indtead of %ld to format size_t type variable. - add macro PGTABLE_SIZE to identify tlb table size. Changes for v6: - Make modification to inappropriate licensed file and bugs according to ScottWood's advice. Thanks Scott for his checking to these patches. - Enable u-boot's running at EL1. - Get rid of compiling warnings originated from cmd_pxe.c. Changes for v5: - fix the generic board_f.c, remove zero_global_data from init_sequence_f array and move it to board_init_f() function with CONFIG_X86 switch. The previous fixup is inaccurate. - Replace __ARMEB__ with __AARCH64EB__ in byteorder.h and unaligned.h, gcc for aarch64 use __AARCH64EB__ and __AARCH64EL__ to identify endian. - Some modification to README.armv8 Changes for v4: - merge arm64 to arm architecture. David Feng (10): fdt_support: 64bit initrd start address support cmd_pxe: remove compiling warnings add weak entry definition arm64: Add tool to statically apply RELA relocations arm64: Turn u-boot.bin back into an ELF file after relocate-rela arm64: Make checkarmreloc accept arm64 relocations arm64: core support arm64: generic board support arm64: board support of vexpress_aemv8a arm64: MAKEALL, filter armv8 boards from LIST_arm MAKEALL | 12 +- Makefile | 39 +++++- arch/arm/config.mk | 3 +- arch/arm/cpu/armv8/Makefile | 17 +++ arch/arm/cpu/armv8/cache.S | 136 +++++++++++++++++++ arch/arm/cpu/armv8/cache_v8.c | 219 +++++++++++++++++++++++++++++++ arch/arm/cpu/armv8/config.mk | 15 +++ arch/arm/cpu/armv8/cpu.c | 43 ++++++ arch/arm/cpu/armv8/exceptions.S | 113 ++++++++++++++++ arch/arm/cpu/armv8/generic_timer.c | 31 +++++ arch/arm/cpu/armv8/gic.S | 106 +++++++++++++++ arch/arm/cpu/armv8/start.S | 164 +++++++++++++++++++++++ arch/arm/cpu/armv8/tlb.S | 34 +++++ arch/arm/cpu/armv8/transition.S | 83 ++++++++++++ arch/arm/cpu/armv8/u-boot.lds | 89 +++++++++++++ arch/arm/include/asm/armv8/mmu.h | 111 ++++++++++++++++ arch/arm/include/asm/byteorder.h | 12 ++ arch/arm/include/asm/cache.h | 5 + arch/arm/include/asm/config.h | 6 + arch/arm/include/asm/gic.h | 49 ++++++- arch/arm/include/asm/global_data.h | 6 +- arch/arm/include/asm/io.h | 15 ++- arch/arm/include/asm/macro.h | 53 ++++++++ arch/arm/include/asm/posix_types.h | 10 ++ arch/arm/include/asm/proc-armv/ptrace.h | 21 +++ arch/arm/include/asm/proc-armv/system.h | 59 ++++++++- arch/arm/include/asm/system.h | 84 ++++++++++++ arch/arm/include/asm/types.h | 4 + arch/arm/include/asm/u-boot.h | 4 + arch/arm/include/asm/unaligned.h | 2 +- arch/arm/lib/Makefile | 20 ++- arch/arm/lib/board.c | 7 +- arch/arm/lib/bootm.c | 24 ++++ arch/arm/lib/crt0_64.S | 113 ++++++++++++++++ arch/arm/lib/interrupts_64.c | 120 +++++++++++++++++ arch/arm/lib/relocate_64.S | 58 ++++++++ board/armltd/vexpress64/Makefile | 8 ++ board/armltd/vexpress64/vexpress64.c | 56 ++++++++ boards.cfg | 1 + common/board_f.c | 20 ++- common/cmd_pxe.c | 4 +- common/fdt_support.c | 66 +++++----- common/image.c | 1 + doc/README.arm64 | 46 +++++++ examples/standalone/stubs.c | 15 +++ include/configs/vexpress_aemv8a.h | 189 ++++++++++++++++++++++++++ include/image.h | 1 + include/linux/linkage.h | 4 + tools/Makefile | 6 + tools/relocate-rela.c | 189 ++++++++++++++++++++++++++ 50 files changed, 2425 insertions(+), 68 deletions(-) create mode 100644 arch/arm/cpu/armv8/Makefile create mode 100644 arch/arm/cpu/armv8/cache.S create mode 100644 arch/arm/cpu/armv8/cache_v8.c create mode 100644 arch/arm/cpu/armv8/config.mk create mode 100644 arch/arm/cpu/armv8/cpu.c create mode 100644 arch/arm/cpu/armv8/exceptions.S create mode 100644 arch/arm/cpu/armv8/generic_timer.c create mode 100644 arch/arm/cpu/armv8/gic.S create mode 100644 arch/arm/cpu/armv8/start.S create mode 100644 arch/arm/cpu/armv8/tlb.S create mode 100644 arch/arm/cpu/armv8/transition.S create mode 100644 arch/arm/cpu/armv8/u-boot.lds create mode 100644 arch/arm/include/asm/armv8/mmu.h create mode 100644 arch/arm/lib/crt0_64.S create mode 100644 arch/arm/lib/interrupts_64.c create mode 100644 arch/arm/lib/relocate_64.S create mode 100644 board/armltd/vexpress64/Makefile create mode 100644 board/armltd/vexpress64/vexpress64.c create mode 100644 doc/README.arm64 create mode 100644 include/configs/vexpress_aemv8a.h create mode 100644 tools/relocate-rela.c -- 1.7.9.5

[U-Boot] Bug in TOP860 code with gcc 4.8.1
by Wolfgang Denk 15 Jan '14

Dear Reinhard, attempting to build the TOP860 code with a GCC 4.8.1 based tool chain (say ELDK v5.5 or Yocto 1.5) gives the following errors: -> ./MAKEALL TOP860 Configuring for TOP860 board... text data bss dec hex filename 165471 21020 17316 203807 31c1f ./u-boot ../common/flash.c: In function 'flash_init': ../common/flash.c:336:20: warning: iteration 128u invokes undefined behavior [-Waggressive-loop-optimizations] info->start[i] = (ulong)addr + 0x10000 * i; ^ ../common/flash.c:334:4: note: containing loop for (i = 0; i < info->sector_count; i++) ^ ... Can you please provide a fix - or is this old hardware and the code should be removed from the U-Boot tree? Best regards, Wolfgang Denk -- DENX Software Engineering GmbH, MD: Wolfgang Denk & Detlev Zundel HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: (+49)-8142-66989-10 Fax: (+49)-8142-66989-80 Email: wd(a)denx.de Life would be so much easier if everyone read the manual.

[U-Boot] XHCI Issues
by Aaron Williams 15 Jan '14

15 Jan '14

Hi all, I am bringing up XHCI support for our SOC and have run into several issues with U-Boot's XHCI code. 1. I need to use a wrapper I call xhci_readl/xhci_writel since all of our I/O is to 64-bit addresses rather than readl/writel which work for PCIe. While xhci_readl/xhci_writel is used in most places there are a few places this is missing. 2. A memory address used by a pointer is not a DMA address on MIPS. On MIPS a wrapper is needed for all read/write operations to descriptors to map the addresses. Generally U-Boot runs in KSEG0 where a pointer always has bit 31 set. In our case we run it in virtual memory with U-Boot loaded at the top of memory (which might be as high as 64GB+256MB). 3. xhci_alloc_virt_device is missing a conversion from big endian to little endian on line 401 of xhci-mem.c. 4. I keep getting hit with BUG_ON(GET_COMP_CODE(le32_to_cpu(event->trans_event.transfer_len != COMP_STOP))); on line 491 in xhci-ring.c. Commenting this out seems to work fine. 5. I also hit the BUG_ON on line 722 of xhci-ring.c since on MIPS a pointer is not a DMA address and the fact that we use 64-bit addresses where pointers are 32-bits. I ran into similar issues with EHCI where again we have to map pointers to physical addresses and use our own wrappers for register accesses. At some point I would love to merge our stuff back into the mainline U-Boot but it's going to be a huge job given that we probably have almost 250K lines of code involved for our MIPS SOCs. -Aaron -- Aaron Williams Software Engineer Cavium, Inc.
