ARM: Fix __bss_start and __bss_end in linker scripts

2013-04-13T20:37:20Z

Commit 3ebd1cbc introduced compiler-generated __bss_start and __bss_end__ and commit c23561e7 rewrote all __bss_end__ as __bss_end. Their merge caused silent and harmless but potentially bug-inducing clashes between compiler- and linker- generated __bss_end symbols. Make __bss_end and __bss_start compiler-only, and create __bss_base and __bss_limit for linker-only use. Signed-off-by: Albert ARIBAUD Reported-by: Benoît Thébaudeau

arm: relocate_code(): Use __image_copy_end for end of relocation

2013-04-12T05:55:05Z

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).

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.

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.

arm: make __bss_start and __bss_end__ compiler-generated

2013-03-12T22:28:32Z

Turn __bss_start and __bss_end__ from linker-generated to compiler-generated symbols, causing relocations for these symbols to change type, from R_ARM_ABS32 to R_ARM_RELATIVE. This should have no functional impact, as it affects references to __bss_start and __bss_end__ only before relocation, and no such references are done. Signed-off-by: Albert ARIBAUD

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

IXP: Fix missing MACH_TYPE_{ACTUX?,PNB3,DVLHOST}

2012-03-26T21:09:25Z

These symbols are no longer defined in Linux-ARM's mach-types files. Replace these with CONFIG_MACH_TYPE instead. Signed-off-by: Marek Vasut Cc: Bryan Hundven Cc: Michael Schwingen

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
