* Drop support for CONFIG_SKIP_RELOCATE_UBOOTWolfgang Denk2010-10-29-38/+0
| | | | | | | | | | | | | | | | For ARM systems, before ELF relocation was introduced, CONFIG_SKIP_RELOCATE_UBOOT coul be used to prevent *COPYING* the U-Boot image from whereever it was loaded to it's link address (CONFIG_SYS_TEXT_BASE). The name was badly chosen, as no relocation was performed at all, it was just a memcpy(). With ELF relocation, this does not work like that any more, and related boards need to be fixed anyway. So don't keep this relict any longer. Signed-off-by: Wolfgang Denk <wd@denx.de> Tested-by: Heiko Schocher <hs@denx.de> Tested-by: Reinhard Meyer <u-boot@emk-elektronik.de>
* Drop support for CONFIG_SYS_ARM_WITHOUT_RELOCWolfgang Denk2010-10-29-1939/+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>
* Replace CONFIG_RELOC_FIXUP_WORKS by CONFIG_NEEDS_MANUAL_RELOCWolfgang Denk2010-10-29-60/+16
| | | | | | | | | | | By now, the majority of architectures have working relocation support, so the few remaining architectures have become exceptions. To make this more obvious, we make working relocation now the default case, and flag the remaining cases with CONFIG_NEEDS_MANUAL_RELOC.

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

* | Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated valueWolfgang Denk2010-10-26-82/+110
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | Rename CONFIG_SYS_INIT_RAM_END into CONFIG_SYS_INIT_RAM_SIZEWolfgang Denk2010-10-26-18/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CONFIG_SYS_INIT_RAM_END was a misnomer as it suggests this might be some end address; to make the meaning more clear we rename it into CONFIG_SYS_INIT_RAM_SIZE No other code changes are performed in this patch, only minor editing of white space (due to the changed length) and the comments was done, where noticed. Note that the code for the PATI and cmi_mpc5xx board configurations looks seriously broken.

By default when U-Boot is compiled with the CONFIG_MP option all secondary cores are brought out of reset and held in spinloops. Setting the "mp_holdoff" environment variable to 'yes' or '1' will cause U-Boot to leave secondary cores in their default state.

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