* Coding Style cleanup: replace leading SPACEs by TABsWolfgang Denk2013-10-14-2/+2

* ARM,relocate: do not use r9Jeroen Hofstee2013-09-23-3/+3
| | | | | | | | | r9 is a platform-specific register in ARM EABI and not per definition a general purpose register. Do not use it while relocating so it can be used for gd. cc: Albert ARIBAUD <albert.u.boot@aribaud.net> Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>

* pxa: fix memory coherency problem after relocationMike Dunn2013-06-22-0/+9
| | | | | | | | On the xscale, the icache must be invalidated and the write buffers drained after writing code over the data bus, even if the caches are disabled. Tested on the pxa270. Signed-off-by: Mike Dunn <mikedunn@newsguy.com>

* arm: make __rel_dyn_{start, end} compiler-generatedAlbert ARIBAUD2013-06-21-9/+2
| | | | | | | | | | | | | | | This change is only done where needed: some linker scripts may contain relocation symbols yet remain unchanged. __rel_dyn_start and __rel_dyn_end each requires its own output section; putting them in relocation sections changes their flags and breaks relocation.

| | | | | | | | | | | | | | | 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.

* remove all references to .dynsymAlbert ARIBAUD2013-06-21-13/+0
| | | | | | | | | | | | | | | | Discard all .dynsym sections from linker scripts Remove all __dynsym_start definitions from linker scripts Remove all __dynsym_start references from the codebase Note: this touches include/asm-generic/sections.h, which is not ARM-specific, but actual uses of __dynsym_start are only in ARM, so this patch can safely go through the ARM repository.

* arm: factorize relocate_code routineAlbert ARIBAUD2013-05-30-0/+112
Replace all relocate_code routines from ARM start.S files with a single instance in file arch/arm/lib/relocate.S. For PXA, this requires moving the dcache unlocking code from within relocate_code into c_runtime_cpu_setup.
