arm: Remove unused relocate_code() parameters

2013-04-12T05:55:07Z

Commit e05e5de7fae5bec79617e113916dac6631251156 made the 2 1st parameters of ARM's relocate_code() useless since it moved the code handling them to crt0.S. So, drop these parameters. Signed-off-by: Benoît Thébaudeau

arm: crt0.S: Remove bogus .globl

2013-04-12T05:55:06Z

The purpose of .globl is to export symbols for ld, not to declare external symbols. By the way, use the ENTRY() and ENDPROC() macros to define functions rather than using .global directly. Signed-off-by: Benoît Thébaudeau

ARM: mmu: Set domain permissions to client access

2013-03-28T08:10:58Z

The 'XN' execute never bit is set in the pagetables. This will prevent speculative prefetches to non executable regions. But the domain permissions are set as master in the DACR register. So the pagetable attribute for 'XN' is not effective. Change the permissions to client. This fixes lot of speculative prefetch aborts seen on OMAP5 secure devices.

ARM: mmu: Introduce weak dram_bank_setup function

2013-03-28T08:06:49Z

Introduce a weak version of dram_bank_setup function to allow a platform specific function. This is used in the subsequent patch to setup dram region without 'XN' attribute in order to enable the region under client permissions.

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.

arm: Enable generic board support

2013-03-15T20:14:00Z

This enables generic board support so that ARM boards can define CONFIG_SYS_GENERIC_BOARD. Signed-off-by: Simon Glass

arm: Use sections header to obtain link symbols

2013-03-15T20:13:58Z

Include this header to get access to link symbols, which are otherwise removed. Signed-off-by: Simon Glass

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

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
