[U-Boot] [PATCH] efikamx: sync Smartbook DDR settings in DCD with those found in Genesi's production U-Boot
by Matt Sealey 24 Aug '12

24 Aug '12

We have no idea where the DCD was derived from for Smartbook support, but they differ from the Smarttop settings, MX51EVK settings and certainly don't correspond to any shipped or development version of U-Boot that Genesi has ever had on any Smartbook. So, copy the calibrated, verified settings from the U-Boot as shipped with every Smartbook since retail production. Remove those few settings that just set the POR defaults which have already been confirmed for the previous Smarttop DCD change. One of the lines is specific to i.MX51 TO3 designs and therefore TO2 Smartbooks will possibly not work so reliably with this new DCD; that said, TO2 Smartbooks basically don't exist at retail and the number of units in the world is less than 5 (3 of which are at the Genesi office or owned by Genesi employees). Many hours of memory testing confirms the new settings are stable.

[U-Boot] [PATCHv2 1/2] mpc85xx: Initial SP alignment is wrong.
by Joakim Tjernlund 23 Aug '12

23 Aug '12

PowerPC mandates SP to be 16 bytes aligned. Furthermore, a stack frame is added, pointing to the reset vector which may in the way when gdb is walking the stack because the reset vector may not accessible depending on emulator settings. Also use a temp register so gdb doesn't pick up intermediate values.

[U-Boot] [PATCH v3 0/19] ARM: SPL: Make more generic, merge DaVinci and OMAP
by Tom Rini 23 Aug '12

23 Aug '12

Hey all, The following patch series merges the davinci and omap-common SPL frameworks into a single framework, CONFIG_SPL_FRAMEWORK along with a few small cleanups to the code to make it a little smaller and more flexible. The end result is that davinci can now opt in on SPL-boots-Linux by just setting the right defines and other platforms would just need to adapt to this framework. In my testing, davinci gains between 300 and 700 bytes for this (not enabling the SPL OS feature) and omap4/5/etc lose just a little bit (from the printf->puts changes). I've tested this on omap3_beagle (xM and classic) and omap4_panda. I don't have any davinci platforms that were previously using SPL so I can't boot-test those changes but since everyone sets CONFIG_SPL_MAX_SIZE, we're OK in that department. To make this series easier to test I've placed it on http://github.com/trini/u-boot WIP/spl-improvements I've looked a little into re-reducing the size and the biggest problem I see is that SPI a lot of informational prints that we don't need, strictly speaking, but are nice in a normal U-Boot context. I'm unsure of the best way to quiet these as I don't like the idea of sprinkling http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54303 and I'm sending another email to discuss that. -- Tom Changes in v2: - Add - Add CONFIG_SYS_SPL_MALLOC_START / SIZE defines from Christian Riesch - Add arch/arm/cpu/arm926ejs/davinci/config.mk to build u-boot.ais - Fix checkpatch warning (u32* boot_params_ptr -> u32 *boot_params_ptr) - Place files into common/spl (due to gcc bug #54303) and include/spl.h - Reorder all of the patches that used to follow this to precede. Changes in v3: CONFIG_SPL_FRAMEWORK perform early init. Fixes the cannot reset problem. - Fix checkpatch.pl warning - Fix thinko, Nand -> SPI (spotted by Prabhakar Lad) - Make u-boot.ais use u-boot.img not u-boot.bin, now that it uses - Make use of board_init_f being a weak function now so that we can - Rename to README.da850, add more direct recovery method (Christian Riesch) Tom Rini (19): Makefile: Move SPL files to clobber, remove from clean spl_mmc: Make FAT checks / calls guarded with CONFIG_SPL_FAT_SUPPORT omap-common: SPL: Add CONFIG_SPL_DISPLAY_PRINT / spl_display_print() omap-common: Fix typo in save_boot_params() in lowlevel_init.S ARM: SPL: Rename omap_boot_device to spl_boot_device ARM: SPL: Rename omap_boot_mode to spl_boot_mode() ARM: SPL: Remove NAND_MODE_HW_ECC from spl_nand.c ARM: SPL: Only call mem_malloc_init if configured ARM: SPL: Add <asm/spl.h> and <asm/arch/spl.h> ARM: SPL: Make spl_mmc.c more generic ARM: SPL: Clean up spl.c / spl_nand.c slightly ARM: SPL: Start hooking in the current SPI SPL support ARM: SPL: Move gpmc_init() to spl_board_init() SPL: Move the omap SPL framework to common/spl spl: Make CONFIG_SPL_FRAMEWORK board_init_f __weak ARM: SPL: Convert davinci to CONFIG_SPL_FRAMEWORK da850: Add README.da850 SPL: Enhance drivers/mtd/nand/nand_spl_load.c SPL: Enhance spi_spl_load to match the other load functions Makefile | 16 +-- README | 9 ++ arch/arm/cpu/arm926ejs/davinci/config.mk | 16 +++ arch/arm/cpu/arm926ejs/davinci/spl.c | 56 ++++------ arch/arm/cpu/armv7/am33xx/board.c | 2 +- arch/arm/cpu/armv7/omap-common/Makefile | 13 --- arch/arm/cpu/armv7/omap-common/boot-common.c | 27 ++++- arch/arm/cpu/armv7/omap-common/hwinit-common.c | 7 +- arch/arm/cpu/armv7/omap-common/lowlevel_init.S | 6 +- arch/arm/cpu/armv7/omap-common/spl_nand.c | 111 -------------------- arch/arm/cpu/armv7/omap3/board.c | 28 +++-- arch/arm/include/asm/arch-am33xx/spl.h | 31 ++++++ arch/arm/include/asm/arch-davinci/spl.h | 28 +++++ arch/arm/include/asm/arch-omap3/spl.h | 34 ++++++ arch/arm/include/asm/arch-omap4/spl.h | 35 ++++++ arch/arm/include/asm/arch-omap4/sys_proto.h | 1 - arch/arm/include/asm/arch-omap5/spl.h | 35 ++++++ arch/arm/include/asm/arch-omap5/sys_proto.h | 1 - arch/arm/include/asm/omap_common.h | 77 -------------- arch/arm/include/asm/spl.h | 29 +++++ board/davinci/da8xxevm/README.da850 | 62 +++++++++++ board/overo/overo.c | 10 -- common/spl/Makefile | 37 +++++++ .../arm/cpu/armv7/omap-common => common/spl}/spl.c | 49 ++++----- .../armv7/omap-common => common/spl}/spl_ymodem.c | 3 +- doc/README.SPL | 1 - drivers/mmc/Makefile | 5 + .../armv7/omap-common => drivers/mmc}/spl_mmc.c | 24 ++--- drivers/mtd/nand/Makefile | 7 +- drivers/mtd/nand/nand_spl_load.c | 89 +++++++++++----- drivers/mtd/spi/spi_spl_load.c | 23 ++-- include/configs/am335x_evm.h | 1 + include/configs/am3517_crane.h | 2 + include/configs/am3517_evm.h | 2 + include/configs/cam_enc_4xx.h | 3 +- include/configs/da850evm.h | 5 + include/configs/devkit8000.h | 1 + include/configs/hawkboard.h | 3 +- include/configs/mcx.h | 2 + include/configs/omap3_beagle.h | 1 + include/configs/omap3_evm_common.h | 1 + include/configs/omap3_overo.h | 1 + include/configs/omap4_common.h | 2 + include/configs/omap5_evm.h | 2 + include/configs/tam3517-common.h | 2 + include/configs/tricorder.h | 1 + include/spl.h | 70 ++++++++++++ spl/Makefile | 1 + 48 files changed, 614 insertions(+), 358 deletions(-) create mode 100644 arch/arm/cpu/arm926ejs/davinci/config.mk delete mode 100644 arch/arm/cpu/armv7/omap-common/spl_nand.c create mode 100644 arch/arm/include/asm/arch-am33xx/spl.h create mode 100644 arch/arm/include/asm/arch-davinci/spl.h create mode 100644 arch/arm/include/asm/arch-omap3/spl.h create mode 100644 arch/arm/include/asm/arch-omap4/spl.h create mode 100644 arch/arm/include/asm/arch-omap5/spl.h create mode 100644 arch/arm/include/asm/spl.h create mode 100644 board/davinci/da8xxevm/README.da850 create mode 100644 common/spl/Makefile rename {arch/arm/cpu/armv7/omap-common => common/spl}/spl.c (85%) rename {arch/arm/cpu/armv7/omap-common => common/spl}/spl_ymodem.c (96%) rename {arch/arm/cpu/armv7/omap-common => drivers/mmc}/spl_mmc.c (91%) create mode 100644 include/spl.h -- 1.7.9.5

[U-Boot] ubifsload does not support relative symbolic link
by Dev Ma 23 Aug '12

23 Aug '12

Hi, I found ubifsload does not support relative symbolic link. A patch in 2009 said that it could resolve relative symlink. It has already been merged into "fs/ubifs/ubifs.c". But it does not work today. Direct symlink, i.e. "to_target" or "/path/to_target", works. But relative symlink, i.e. "./to_target" or "../path/to_target", does not work. I read ubifs.c in kernel source tree, and found folder "." and ".." are treated differently. Can anybody give a solution? Thanks, Dev
