SMRDATA in a/a/c/arm920t/at91/lowlevel_init.c has wrong size. This patch reduces it to correct size of 40 byte. Signed-off-by: Andreas Bießmann <biessmann(a)corscience.de> --- Dear all, I thougt about a problem in lowlevel_init() cause of errornous booting from NOR flash on at91rm9200ek last night .

Hello, may I ask if there is reason why merge commits don't have a summary? I find those summaries (enabled with git config [--global] merge.summary true) very hand to see what was changed with the merge commit. Regards, Alexander

[U-Boot] errno confusion for fw_env?
by Detlev Zundel 10 Mar '11

10 Mar '11

Hi, with current master I tried to cross-compile a fw_env tool for the da850evm configuration. So I tried the "standard scheme" (means it worked a few years ago) make distclean make da850evm_config make env Doing this I noticed that commit abd315a1357ab05e82f0d61ebad666bc0d5378c3 disabled cross-compilation. So I reverted the commit locally on my tree to enable cross-compilation again, but now I get: [dzu@pollux u-boot-testing (master)]$ make env make -C tools/env all MTD_VERSION= make[1]: Entering directory `/work/dzu/git/u-boot-testing/tools/env' arm-linux-gcc -Wall -DUSE_HOSTCC -I/work/dzu/git/u-boot-testing/include crc32.c fw_env.c fw_env_main.c -o fw_printenv /opt/eldk-4.2-2008-11-24/usr/bin/../lib/gcc/arm-linux-gnueabi/4.2.2/../../../../arm-linux-gnueabi/bin/ld: errno: TLS definition in /opt/eldk-4.2-2008-11-24/usr/../arm/lib/libc.so.6 section .tbss mismatches non-TLS reference in /tmp/cc45c402.o /opt/eldk-4.2-2008-11-24/usr/../arm/lib/libc.so.6: could not read symbols: Bad value collect2: ld returned 1 exit status make[1]: *** [fw_printenv] Error 1 make[1]: Leaving directory `/work/dzu/git/u-boot-testing/tools/env' make: *** [env] Error 2 The cross-compilation and the "-DUSE_HOSTCC" doesn't look right somehow. And moreover we now pull in the "U-Boot errno" stuff for a regular user-space tool through "-I$(SRCTREE)/include". The latter comes from this commit: commit f3b6d528e4dd719640a4bfcd954f4e4c7f5db0d6 Author: Grant Erickson <gerickson(a)nuovations.com> Date: Tue May 6 16:18:00 2008 -0700 Fix Compilation Errors with 'tools/env/fw_printenv' In the current top-of-tree, 1.3.3.-rc2, the optional tool 'tools/env/fw_printenv' fails to compile for two reasons: 1) The header watchdog.h cannot be found. 2) The header zlib.h is picked up from the tool chain rather than the project causing a prototype conflict for crc32. This patch addresses both of these issues. Platforms Tested On: - AMCC "Kilauea" Signed-off-by: Grant Erickson <gerickson(a)nuovations.com> It was probably not anticipated that this now picks up errno.h from the project as well. Does anybody have a good idea on how to tackle this?

[U-Boot] [PATCH 0/8] armv7: cache maintenance operations
by Aneesh V 01 Mar '11

01 Mar '11

With D-cache and MMU enabled for ARM in u-boot it becomes imperative to support a minimal set of cache maintenance operations and necessary initializations before enabling MMU. This series of patches attempt to do the following for armv7: * Necessary initialization sequence before enabling MMU that includes invalidation of TLB, data caches, branch predictor array etc. * Framework for supporting SOC specific outer caches in a generic manner (using a structure of function pointers - inspired by the Linux implementation) * Generic armv7 cache maintenance operations for caches known to the CPU * Support for ARM PL310 L2 cache controller used in OMAP4 * Cleanup of the cleanup_before_linux() function * Adapting all armv7 SOCs to use the new framework and removing duplicated code Testing: * Extensive testing on OMAP4430SDP and OMAP3430SDP by creating coherency issues and solving them using the maintenance routines - Eg: memfill a region of memory with a known pattern - Invalidate the region - Read back and compare the region with the original pattern - If match fails it means that invalidate is successful - Now add a flush call just before the invalidate - If match succeeds it means that flush was successful - Outer caches were tested with experiments involving making the function pointers NULL * Kernel booting on OMAP4430SDP and OMAP3430SDP Aneesh V (8): arm: make default implementation of cache_flush() weakly linked armv7: cache maintenance operations for armv7 armv7: integrate cache maintenance support arm: minor fixes for cache and mmu handling armv7: add PL310 support to u-boot armv7: adapt omap4 to the new cache maintenance framework armv7: adapt omap3 to the new cache maintenance framework armv7: adapt s5pc1xx to the new cache maintenance framework arch/arm/cpu/armv7/Makefile | 2 +- arch/arm/cpu/armv7/cache_v7.c | 359 +++++++++++++++++++++++++ arch/arm/cpu/armv7/config.mk | 2 +- arch/arm/cpu/armv7/cpu.c | 47 ++-- arch/arm/cpu/armv7/omap3/Makefile | 1 - arch/arm/cpu/armv7/omap3/board.c | 151 +++++++++-- arch/arm/cpu/armv7/omap3/cache.S | 263 ------------------ arch/arm/cpu/armv7/omap3/lowlevel_init.S | 30 ++ arch/arm/cpu/armv7/omap4/board.c | 25 ++- arch/arm/cpu/armv7/omap4/lowlevel_init.S | 17 ++ arch/arm/cpu/armv7/s5pc1xx/cache.S | 86 +------ arch/arm/cpu/armv7/s5pc1xx/clock.c | 12 + arch/arm/cpu/armv7/start.S | 18 ++- arch/arm/include/asm/arch-omap3/omap3.h | 20 ++ arch/arm/include/asm/arch-omap3/sys_proto.h | 10 +- arch/arm/include/asm/arch-omap4/omap4.h | 6 + arch/arm/include/asm/arch-omap4/sys_proto.h | 3 +- arch/arm/include/asm/arch-s5pc1xx/sys_proto.h | 4 +- arch/arm/include/asm/armv7.h | 63 +++++ arch/arm/include/asm/pl310.h | 49 ++++ arch/arm/lib/Makefile | 1 + arch/arm/lib/board.c | 6 + arch/arm/lib/cache-cp15.c | 18 ++- arch/arm/lib/cache-pl310.c | 114 ++++++++ arch/arm/lib/cache.c | 20 +- include/common.h | 5 +- include/configs/omap4_panda.h | 6 +- include/configs/omap4_sdp4430.h | 6 +- 28 files changed, 929 insertions(+), 415 deletions(-) create mode 100644 arch/arm/cpu/armv7/cache_v7.c delete mode 100644 arch/arm/cpu/armv7/omap3/cache.S create mode 100644 arch/arm/include/asm/armv7.h create mode 100644 arch/arm/include/asm/pl310.h create mode 100644 arch/arm/lib/cache-pl310.c
