* x86: Allow relocation code to build without text baseSimon Glass2015-08-05-6/+11
| | | | | | | | | This code currently requires CONFIG_SYS_TEXT_BASE but this should be unnecessary. As a first step, remove the build-time limitation and report an error instead. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
* x86: Support skipping relocation for EFISimon Glass2015-08-05-0/+6
| | | | | | | | When running as an EFI application we must skip relocation. Add support for this in the x86 relocation code. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
* x86: Drop unused copy_fdt_to_ram()Simon Glass2015-08-05-18/+0
| | | | | | | | This is now handled by generic U-Boot code so we do not need an x86 version. It is no-longer called, so remove it. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
* x86: Panic if there is no relocation dataSimon Glass2014-11-25-0/+3
| | | | | | | | | This normally indicates a problem which will prevent relocation from functioning, resulting in a hang. Panic in this case to make it easier to debug. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
* x86: Use correct printf() format string for uintptr_tSimon Glass2014-10-27-1/+2
| | | | | | Use the inttypes header file to provide this. Signed-off-by: Simon Glass <sjg@chromium.org>

* x86: Declare global_data pointer when it is usedSimon Glass2013-05-13-0/+2
| | | | | | | | Several files use the global_data pointer without declaring it. This works because the declaration is currently a NOP. But still it is better to fix this so that x86 lines up with other archs. Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: Use sections header to obtain link symbolsSimon Glass2013-03-15-0/+1
| | | | | | | These are defined in asm-generic/sections.h, so remove them from architecture-specific files. Signed-off-by: Simon Glass <sjg@chromium.org>
* Introduce generic pre-relocation board_f.cSimon Glass2013-03-15-4/+4
| | | | | | | | | | | | This file handles common pre-relocation init for boards which use the generic framework. It starts up the console, DRAM, performs relocation and then jumps to post-relocation init.

* x86: Add error checking to x86 relocation codeSimon Glass2013-03-04-2/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This does not actually change normal behaviour, but adds a check that should detect corruption of relocation data (e.g. by using BSS data prior to relocation). Also add additional debugging output when enabled. During this investigation, two situations have been seen: 1. calculate_relocation_address(): uintptr_t size = (uintptr_t)&__bss_end - (uintptr_t)&__text_start; turns into 111166f: b8 83 c4 17 01 mov $0x117c483,%eax whih is beyond the end of bss: 0117b484 g .bss 00000000 __bss_end Somehow the __bss_end here is 255 bytes ahead. 2. do_elf_reloc_fixups(): uintptr_t size = (uintptr_t)&__bss_end - (uintptr_t)&__text_start; Here the __text_start is 0 in the file: 1111d9f: bb a0 e0 13 01 mov $0x113e0a0,%ebx 1111da4: 81 ef 00 00 00 00 sub $0x0,%edi As it happens, both of these are in pre-relocation code. For these reasons we silent check and ignore bad relocations. Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: Support relocation of FDT on start-upSimon Glass2013-03-04-0/+17
| | | | | | | With CONFIG_OF_CONTROL we may have an FDT in the BSS region. Relocate it up with the rest of U-Boot to keep the rest of memory free. Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: Make the upper bound on relocated symbols closed instead of openGabe Black2012-12-06-1/+1
| | | | | | This seems to be a bug. Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: Fix off-by-one error in do_elf_reloc_fixups()Duncan Laurie2012-12-06-1/+1
| | | | | | | | | | The use of post-increment with a do-while loop results in the loop going one step too far when handling relocation fixups. In about 1/100 cases this would cause it to hang. Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: Convert board_init_f_r to a processing loopGraeme Russ2012-01-04-28/+4
| | | | | | | | | | | | | | Create an init function array for board_init_f_r - This finalises the migration to a purely array based initialisation mechanism Also tweak a few comments while we are at it so everything is 'correct' -- Changes for v2: - Renamed to a more apt name - Fix bug in set_reloc_flag_r - Re-instate gd->flags = boot_flags; in board_init_f - Added commit message
