* Drop support for CONFIG_SYS_ARM_WITHOUT_RELOCWolfgang Denk2010-10-29-1673/+8
| | | | | | | | | | | | | | | | When this define was introduced, the idea was to provide a soft migration path for ARM boards to get adapted to the new relocation support. However, other recent changes led to a different implementation (ELF relocation), where this no longer works. By now CONFIG_SYS_ARM_WITHOUT_RELOC does not only not help any more, but it actually hurts because it obfuscates the actual code by sprinkling it with lots of dead and non-working debris. So let's make a clean cut and drop CONFIG_SYS_ARM_WITHOUT_RELOC. Signed-off-by: Wolfgang Denk <wd@denx.de> Tested-by: Heiko Schocher <hs@denx.de> Tested-by: Reinhard Meyer <u-boot@emk-elektronik.de>

* ARM: use the same branch insn on all architecturesWolfgang Denk2010-10-26-10/+10
| | | | | | | | | | | | | | | For the "fixloop" implementation in start.S a number of different instructions was used. Unify code so all architectures use "blo" here because it is more robust in case of incorrect alignments.

* arm1176: fix relocationDarius Augulis2010-10-26-61/+97
| | | | | | | | | | Fix relocation code for arm1176, do it like other ARM CPU's are doing. Tested only with CONFIG_SKIP_RELOCATE_UBOOT defined and using nand_spl (booting from nand).

* Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated valueWolfgang Denk2010-10-26-53/+56
| | | | | | | | | | | | | | | | | | CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not being able to use "sizeof(struct global_data)" in assembler files. Recent experience has shown that manual synchronization is not reliable enough. This patch renames CONFIG_SYS_GBL_DATA_SIZE into GENERATED_GBL_DATA_SIZE which gets automatically generated by the asm-offsets tool. In the result, all definitions of this value can be deleted from the board config files. We have to make sure that all files that reference such data include the new <asm-offsets.h> file. No other changes have been done yet, but it is obvious that similar changes / simplifications can be done for other, related macro definitions as well.

* PXA: Fix reloc, Push lowlevel init into C codeMarek Vasut2010-10-19-214/+359
| | | | | | | | | | | | | | Firstly, this fixes relocation issues. I had to use part of Dcache as RAM for a while. I also moved around the lowlevel init code. It turned out so most of the lowlevel init code ended in cpu.c (and eventually was rewritten into C). This will also allow easier operation with FDT, multi-CPU-model support etc. in later releases. NOTE: This breaks most of the PXA boards (actually, the reloc stuff did already, this only finishes the doom). Signed-off-by: Marek Vasut <marek.vasut@gmail.com>

| * at91: Add arch_preboot_os which disables PIT in a faster wayAlexander Stein2010-10-05-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | When disabled the PIT runs until it reaches the CPIV value. The Linux PIT driver stops the PIT and waits until it stopped. This can take over 100ms. Simply stopping in u-boot isn't sufficient as the PIT will still be running when Linux is waiting until it stopped. So, we stop it in u-boot by setting the compare value to a value slightly greater than the current running counter to make the PIT stopped in short time.
