[U-Boot] [PATCH v3 0/23] tegra: warmboot (suspend / resume) support
by Simon Glass 06 Oct '12

06 Oct '12

This series adds support for warm boot, allowing the device to suspend and resume. U-Boot sets up some 'warm boot' code in a special area such that the SOC can find it on a resume. This code is responsible for setting up memory and clocked and then allowing the OS to continue where it left off. Also included here is support for the EMC, which allows setting the memory timings correctly in U-Boot for maximum speed operation. Note: sign-offs are needed from Jimmy Zhang, Wei Ni and Yen Lin. Changes in v2: - Add check of undocumented values in hidrev register - Add debug() output to EMC - Add new fdtdec_locate_array() function - Add patch to find DVC bus number - Check error return from pmu_set_nominal() in debug mode - Move EMC tables to device tree - Move structs shared between A9 and AVP into warmboot.h header file - New patch to add low-level clock functions - Rely on compiler to optimise out debug_print_vector() - Remove unused crypto code - Remove unused crypto code from crypto.c - Removed check for nominal voltage (not needed as it is done just before) - Split PMU code into separate TPS6586X driver - Tidy SDRAM range check in warmboot_prepare_code() - Tidy whitespace problems - Use const for sbox arrays - Use low-level clock functions in warmboot code instead of register access Changes in v3: - Add apb_misc.h header file in new patch - Add better error reporting when EMC setup fails - Add new fdtdec_next_compatible_subnode() patch - Add new patch to put abs() in common.h - Fix CONFIG_TEGRA_I2C define - Move abs() macro into common.h - Support nvidia,use-ram-code binding option for EMC - Try to return a useful error code when EMC config fails Jimmy Zhang (3): tegra: Add EMC support for optimal memory timings tegra: Add PMU to manage power supplies tegra: Add EMC settings for Seaboard Simon Glass (14): fdt: Add function to locate an array in the device tree fdt: Add function to return next compatible subnode Add abs() macro to return absolute value i2c: Add TPS6586X driver tegra: Move ap20.h header into arch location tegra: Add functions to access low-level Osc/PLL details tegra: Add tegra_get_chip_type() to detect SKU tegra: Add header file for APB_MISC register tegra: Set up PMU for Nvidia boards tegra: Set up warmboot code on Nvidia boards fdt: tegra: Add EMC node to device tree tegra: i2c: Add function to find DVC bus tegra: fdt: Add EMC data for Tegra2 Seaboard tegra: Enable LP0 on Seaboard Wei Ni (1): tegra: Turn off power detect in board init Yen Lin (5): Add AES crypto library tegra: Add crypto library for warmboot code tegra: Add flow, gp_padctl, fuse, sdram headers tegra: Add warmboot implementation tegra: Setup PMC scratch info from ap20 setup arch/arm/cpu/armv7/tegra2/Makefile | 4 + arch/arm/cpu/armv7/tegra2/ap20.c | 44 ++- arch/arm/cpu/armv7/tegra2/board.c | 4 +- arch/arm/cpu/armv7/tegra2/clock.c | 32 + arch/arm/cpu/armv7/tegra2/crypto.c | 230 ++++++++ arch/arm/cpu/armv7/tegra2/crypto.h | 36 ++ arch/arm/cpu/armv7/tegra2/emc.c | 286 ++++++++++ arch/arm/cpu/armv7/tegra2/pmu.c | 70 +++ arch/arm/cpu/armv7/tegra2/warmboot.c | 382 +++++++++++++ arch/arm/cpu/armv7/tegra2/warmboot_avp.c | 250 ++++++++ arch/arm/cpu/armv7/tegra2/warmboot_avp.h | 81 +++ arch/arm/dts/tegra20.dtsi | 7 + .../tegra2 => include/asm/arch-tegra2}/ap20.h | 7 + arch/arm/include/asm/arch-tegra2/apb_misc.h | 36 ++ arch/arm/include/asm/arch-tegra2/clk_rst.h | 3 + arch/arm/include/asm/arch-tegra2/clock.h | 22 + arch/arm/include/asm/arch-tegra2/emc.h | 113 ++++ arch/arm/include/asm/arch-tegra2/flow.h | 36 ++ arch/arm/include/asm/arch-tegra2/fuse.h | 39 ++ arch/arm/include/asm/arch-tegra2/gp_padctrl.h | 73 +++ arch/arm/include/asm/arch-tegra2/pmu.h | 30 + arch/arm/include/asm/arch-tegra2/sdram_param.h | 148 +++++ arch/arm/include/asm/arch-tegra2/tegra2.h | 25 + arch/arm/include/asm/arch-tegra2/tegra_i2c.h | 7 + arch/arm/include/asm/arch-tegra2/warmboot.h | 150 +++++ board/nvidia/common/Makefile | 1 + board/nvidia/common/board.c | 41 ++- board/nvidia/common/emc.c | 53 ++ board/nvidia/common/emc.h | 29 + board/nvidia/dts/tegra2-seaboard.dts | 72 +++ drivers/i2c/tegra_i2c.c | 14 + drivers/power/Makefile | 1 + drivers/power/tps6586x.c | 280 +++++++++ include/aes.h | 70 +++ include/common.h | 13 + include/configs/seaboard.h | 8 + include/configs/tegra2-common.h | 17 + include/fdtdec.h | 38 ++ include/tps6586x.h | 68 +++ lib/Makefile | 1 + lib/aes.c | 598 ++++++++++++++++++++ lib/fdtdec.c | 28 + 42 files changed, 3443 insertions(+), 4 deletions(-) create mode 100644 arch/arm/cpu/armv7/tegra2/crypto.c create mode 100644 arch/arm/cpu/armv7/tegra2/crypto.h create mode 100644 arch/arm/cpu/armv7/tegra2/emc.c create mode 100644 arch/arm/cpu/armv7/tegra2/pmu.c create mode 100644 arch/arm/cpu/armv7/tegra2/warmboot.c create mode 100644 arch/arm/cpu/armv7/tegra2/warmboot_avp.c create mode 100644 arch/arm/cpu/armv7/tegra2/warmboot_avp.h rename arch/arm/{cpu/armv7/tegra2 => include/asm/arch-tegra2}/ap20.h (96%) create mode 100644 arch/arm/include/asm/arch-tegra2/apb_misc.h create mode 100644 arch/arm/include/asm/arch-tegra2/emc.h create mode 100644 arch/arm/include/asm/arch-tegra2/flow.h create mode 100644 arch/arm/include/asm/arch-tegra2/fuse.h create mode 100644 arch/arm/include/asm/arch-tegra2/gp_padctrl.h create mode 100644 arch/arm/include/asm/arch-tegra2/pmu.h create mode 100644 arch/arm/include/asm/arch-tegra2/sdram_param.h create mode 100644 arch/arm/include/asm/arch-tegra2/warmboot.h create mode 100644 board/nvidia/common/emc.c create mode 100644 board/nvidia/common/emc.h create mode 100644 drivers/power/tps6586x.c create mode 100644 include/aes.h create mode 100644 include/tps6586x.h create mode 100644 lib/aes.c -- 1.7.7.3

[U-Boot] [PATCH v2] ARM: Add X600 board support (SPEAr600 based)
by Stefan Roese 04 Oct '12

04 Oct '12

This patch adds support for the X600 SPEAr600 based board. Its also the first SPEAr600 board that uses the newly introduced SPEAr600 SPL support. Xloader is not necessary any more. By using the new "u-boot.spr" make target, one image will generated containing both, U-Boot SPL (with mkimage header as needed by the SPEAr BootROM, and the main U-Boot with mkimage header.

[U-Boot] [PATCH 0/2] Add support for MINI2440 (s3c2440)
by Gabriel Huau 03 Oct '12

03 Oct '12

>From the last time, I removed the patch about the PLL initialization because it's board specific. I added a new patch for s3c440 gpio driver. Now in the board file we have no more magic bloat. >> +/* >> + * When booting from NAND, it is impossible to access the lowest addresses >> + * due to the SteppingStone being in the way. Luckily the NOR doesn't really >> + * care about the highest 16 bits of address, so we set the controlers >> + * registers to go and poke over there, instead. >> + */ >> +#define PHYS_FLASH_1 0x0 >> +#define CONFIG_SYS_FLASH_BASE 0x0 > >Urghh... this sounds very much like a serious design issue? About this point, I ported it from the old version uboot as well. It may need some investigation, but I remember it was a big problem with this board. In the case of a NAND boot, we don't have access to NOR because the SteppingStone (SRAM) is mapped at the same range. Gabriel Huau (2): Add GPIO Driver and IOMUX definition for S3C2440 Add support for MINI2440 (s3c2440).

[U-Boot] [PATCH 0/6] add zip command support for uboot
by adrian.wenl＠gmail.com 29 Sep '12

29 Sep '12

From: Lei Wen <leiwen(a)marvell.com> This patch set add zip command support for uboot. The first two patches import deflate and trees functions from zlib 1.2.5 without any change. While the third patch did the necessary change to make the import file could be built passed in uboot environment. The fourth patch make us could zip the memory from 0 in the address space. The latter fifth and sixth patch does the adding gzip lib function exporting and zip command support. Patch set test with zip&unzip and compared with original memory content. Lei Wen (6): lib: zlib: import deflate source file from 1.2.5 lib: zlib: import trees file from 1.2.5 lib: zlib: include deflate into zlib build lib: zlib: remove the limitation for cannot using 0 as start lib: add gzip lib function callback common: add zip command support common/Makefile | 1 + common/cmd_zip.c | 60 ++ include/common.h | 7 + include/u-boot/zlib.h | 40 +- lib/Makefile | 1 + lib/gzip.c | 143 ++++ lib/zlib/deflate.c | 1831 +++++++++++++++++++++++++++++++++++++++++++++++++ lib/zlib/deflate.h | 342 +++++++++ lib/zlib/trees.c | 1244 +++++++++++++++++++++++++++++++++ lib/zlib/trees.h | 128 ++++ lib/zlib/zlib.c | 8 + lib/zlib/zutil.h | 4 + 12 files changed, 3804 insertions(+), 5 deletions(-) create mode 100644 common/cmd_zip.c create mode 100644 lib/gzip.c create mode 100644 lib/zlib/deflate.c create mode 100644 lib/zlib/deflate.h create mode 100644 lib/zlib/trees.c create mode 100644 lib/zlib/trees.h -- 1.7.5.4

[U-Boot] UBI problems on current u-bo
by Holger Brunck 28 Sep '12

28 Sep '12

Hi Stefan, I address this question to you because one of your commits is connected to this problem, but other hints from other readers are also welcome ;-) . We have a kirkwood based board with a micron NAND flash. We have one ubi device created on the NAND flash and inside the device we have one ubi volume were we store our linux kernel. At startup we attach to the ubi device, to be able to readout the kernel image. On our old u-boot branch which based on v2009.08 we hadn't any problems. Now after upgrading to the newest u-boot version we saw in some rarely cases our u-boot get stuck when we try to attach: => ubi part ubi0 Creating 1 MTD partitions on "nand0": 0x000000000000-0x000008000000 : "mtd=0" UBI: attaching mtd1 to ubi0 UBI: physical eraseblock size: 131072 bytes (128 KiB) UBI: logical eraseblock size: 129024 bytes UBI: smallest flash I/O unit: 2048 UBI: sub-page size: 512 UBI: VID header offset: 512 (aligned 512) UBI: data offset: 2048 UBI: fixable bit-flip detected at PEB 71 And after this u-boot gets stuck until the end of days and we have to force a reboot, but the u-boot gets stuck again. If I revert your commit: commit 1b1f9a9d00447d9eab32ae5633f60a106196b75f Author: Stefan Roese <sr(a)denx.de> Date: Mon May 17 10:00:51 2010 +0200 UBI: Ensure that "background thread" operations are really executed the u-boot don't get stuck: => ubi part ubi0 Creating 1 MTD partitions on "nand0": 0x000000000000-0x000008000000 : "mtd=0" UBI: attaching mtd1 to ubi0 UBI: physical eraseblock size: 131072 bytes (128 KiB) UBI: logical eraseblock size: 129024 bytes UBI: smallest flash I/O unit: 2048 UBI: sub-page size: 512 UBI: VID header offset: 512 (aligned 512) UBI: data offset: 2048 UBI: fixable bit-flip detected at PEB 71 UBI: attached mtd1 to ubi0 UBI: MTD device name: "mtd=0" UBI: MTD device size: 128 MiB UBI: number of good PEBs: 1024 UBI: number of bad PEBs: 0 UBI: max. allowed volumes: 128 UBI: wear-leveling threshold: 4096 UBI: number of internal volumes: 1 UBI: number of user volumes: 9 UBI: available PEBs: 623 UBI: total number of reserved PEBs: 401 UBI: number of PEBs reserved for bad PEB handling: 10 UBI: max/mean erase counter: 8193/3082 => This is the reason why our old u-boot works, because the background thread seems to be not or not completely executed... If I boot a recent linux kernel the kernel also reports an "fixable bit-flip detected at PEB 71" but linux is able to really fix this bit flip and is able to work as expceted, even u-boot is afterwards bootable because the bitflip is corrected and gone. Now I could revert your commit in my local branch and then it seems to work, but I think this is not a good solution because I expect that the real error is somewhere in the UBI layer in u-boot and already fixed in current linux. AFAIK the ubi layer was initially copied from linux, but it seems that the bugfixes are not backported in the last years. Any thoughts or ideas? Best regards Holger

[U-Boot] [PATCH v1 0/5] env: handle special variables and selective env default
by Gerlando Falauto 18 Sep '12

18 Sep '12

This patchset modifies the handling of all the operations on the environment (set/import/default) so to unify handling of special variables. On top of that we implement a selective "env default". A selective "env import" would imply a user API change and should therefore be discussed separately. Changes in the syntax (user API): - "env default" -f: override write-once variables, -a means all First patch is a cosmetic prerequisite to the second patch which constifies serial_assign(). Changes from v0: - checkpatch cleanup - removed himport_ex() - removed warning for serial_assign() - env import NOT implemented here Gerlando Falauto (5): serial: cosmetic checkpatch compliance serial: constify serial_assign() env: unify logic to check and apply changes env: check and apply changes on delete/destroy env: make "env default" selective, check and apply README | 2 + common/cmd_nvedit.c | 209 +++++++++++++++++++++++++++++++--------------- common/env_common.c | 35 +++++++- common/serial.c | 51 ++++++------ include/config_cmd_all.h | 1 + include/environment.h | 12 +++ include/search.h | 23 +++++- include/serial.h | 19 ++-- lib/hashtable.c | 61 ++++++++++++-- 9 files changed, 300 insertions(+), 113 deletions(-)
