u-boot.git/arch/sh/cpu, branch v2013.04

Merge branch 'master' of git://git.denx.de/u-boot-arm

2013-03-18T18:37:18Z

Albert's rework of the linker scripts conflicted with Simon's making everyone use __bss_end. We also had a minor conflict over README.scrapyard being added to in mainline and enhanced in u-boot-arm/master with proper formatting. Conflicts: arch/arm/cpu/ixp/u-boot.lds arch/arm/cpu/u-boot.lds arch/arm/lib/Makefile board/actux1/u-boot.lds board/actux2/u-boot.lds board/actux3/u-boot.lds board/dvlhost/u-boot.lds board/freescale/mx31ads/u-boot.lds doc/README.scrapyard include/configs/tegra-common.h Build tested for all of ARM and run-time tested on am335x_evm.

Replace __bss_end with bss_end

2013-03-15T20:13:54Z

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

Refactor linker-generated arrays

2013-03-12T22:28:40Z

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.

common: Discard the __u_boot_cmd section

2012-10-22T15:29:42Z

The command declaration now uses the new LG-array method to generate list of commands. Thus the __u_boot_cmd section is now superseded and redundant and therefore can be removed. Also, remove externed symbols associated with this section from include/command.h . Signed-off-by: Marek Vasut Cc: Joe Hershberger Cc: Mike Frysinger

common: Add .u_boot_list into all linker files

2012-10-22T15:29:42Z

Add section for the linker-generated lists into all possible linker files, so that everyone can easily use these lists. This is mostly a mechanical adjustment. Signed-off-by: Marek Vasut Cc: Joe Hershberger Cc: Mike Frysinger

sh: modify checkcpu() for SH-4A

2012-08-08T00:50:41Z

Even if using CPU is SH-4A, the previous code always put "SH4". This patch fixes it. Signed-off-by: Yoshihiro Shimoda Signed-off-by: Nobuhiro Iwamatsu

sh: avoid multiple definition errors with cache funcs

2011-12-02T04:46:21Z

Recent builds for SH4 boards fail with a lot of errors like: cmd_mem.o: In function 'dcache_invalid_range': include/asm/cache.h:25: multiple definition of 'dcache_invalid_range' include/asm/cache.h:25: first defined here This is due to the funcs being defined in the header, but not static or inline or extern. So move them to the sh4-specific cache.c file. Signed-off-by: Mike Frysinger Signed-off-by: Nobuhiro Iwamatsu

sh: only add -mno-fdpic if the compiler supports it

2011-12-02T04:46:20Z

Not all SuperH toolchains support -mno-fdpic. Chances are good that if the flag doesn't work, it isn't defaulting to the FDPIC ABI, so the flag isn't needed. So only add it if it is actually supported. Signed-off-by: Mike Frysinger Signed-off-by: Nobuhiro Iwamatsu

punt unused clean/distclean targets

2011-10-15T20:20:36Z

The top level Makefile does not do any recursion into subdirs when cleaning, so these clean/distclean targets in random arch/board dirs never get used. Punt them all. MAKEALL didn't report any errors related to this that I could see. Signed-off-by: Mike Frysinger

sh: sh2a: Add sh2a optimize to config.mk

2011-08-22T04:16:08Z

Only the optimization of sh2 had been supported up. This adds the optimization of sh2a. Signed-off-by: Nobuhiro Iwamatsu Signed-off-by: Nobuhiro Iwamatsu
