* arm: ep9315: Return back Cirrus Logic EDB9315A board supportSergey Kostanbaev2014-07-04-27/+436

* arm: move exception handling out of start.S filesAlbert ARIBAUD2014-05-15-215/+4
| | | | | | | | Exception handling is basically identical for all ARM targets. Factorize it out of the various start.S files and into a single vectors.S file, and adjust linker scripts accordingly. Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net>
* arm: remove unneeded symbol offsets and _TEXT_BASEAlbert ARIBAUD2014-02-26-26/+0
| | | | | | | | Remove the last uses of symbol offsets in ARM U-Boot. Remove some needless uses of _TEXT_BASE. Remove all _TEXT_BASE definitions. Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net>

* ARM: merge commonly-defined PLATFORM_RELFLAGSMasahiro Yamada2014-01-24-7/+0
| | | | | | | | | | | | | | Before this commit, all arch/arm/cpu/${CPU}/config.mk except ARMv8 had the same option: $(call cc-option,-mshort-load-bytes,$(call cc-option,-malignment-traps,)) This commit moves it into arch/arm/config.mk. If the compiler does not support the option, it is ignored by $(call cc-option,...). So this commit gives no harm to ARMv8. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

* arm: make __image_copy_{start, end} compiler-generatedAlbert ARIBAUD2013-06-21-1/+5
| | | | | | | | | | | | | | | This change is only done where needed: some linker scripts may contain __image_copy_{start,end} yet remain unchanged. Also, __image_copy_end needs its own section; putting it in relocation sections changes their flags and makes relocation break.

| | | | | | | | | | | Replace all relocate_code routines from ARM start.S files with a single instance in file arch/arm/lib/relocate.S.

* arm: relocate_code(): Use __image_copy_end for end of relocationBenoît Thébaudeau2013-04-12-1/+8
| | | | | | | | | | | | Use __image_copy_end instead of __bss_start for the end of the image to relocate. This is the same as commit 033ca72, but applied to all ARM start.S. This is a more appropriate symbol naming for an image copy & relocate feature, and this also saves a useless copy of data put between __image_copy_end and __bss_start in linker scripts (e.g. relocation information, or MMU initialization tables used only before jumping to the relocated image).

| * Refactor linker-generated arraysAlbert ARIBAUD2013-03-12-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Refactor linker-generated array code so that symbols which were previously linker-generated are now compiler- generated. This causes relocation records of type R_ARM_ABS32 to become R_ARM_RELATIVE, which makes code which uses LGA able to run before relocation as well as after. Note: this affects more than ARM targets, as linker- lists span possibly all target architectures, notably PowerPC.

* | Replace __bss_end__ with __bss_endSimon Glass2013-03-15-2/+2
|/ | | | | | | | | | | | | Note this is a tree-wide change affecting multiple architectures. At present we use __bss_start, but mostly __bss_end__. This seems inconsistent and in a number of places __bss_end is used instead. Change to use __bss_end for the BSS end symbol throughout U-Boot. This makes it possible to use the asm-generic/sections.h file on all archs. Signed-off-by: Simon Glass <sjg@chromium.org>

Also, rewrite the C runtime setup and make functions board_init_*() and relocate_code() behave according to normal C semantics (no jumping across the C stack any more, etc). Some SPL targets had to be touched because they use start.S explicitly or for some reason; the relevant maintainers and custodians are cc:ed. Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net>

* Reduce build timesWolfgang Denk2011-11-03-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | U-Boot Makefiles contain a number of tests for compiler features etc. which so far are executed again and again. On some architectures (especially ARM) this results in a large number of calls to gcc. This patch makes sure to run such tests only once, thus largely reducing the number of "execve" system calls. Example: number of "execve" system calls for building the "P2020DS" (Power Architecture) and "qong" (ARM) boards, measured as: -> strace -f -e trace=execve -o /tmp/foo ./MAKEALL <board> -> grep execve /tmp/foo | wc -l Before: After: Reduction: ================================== P2020DS 20555 15205 -26% qong 31692 14490 -54% As a result, built times are significantly reduced, typically by 30...50%.
