* nand: mxc: Switch NAND SPL to generic SPLBenoît Thébaudeau2013-04-121-7/+7
| | | | | | | | | This also fixes support for mx31pdk and tx25, which had been broken by commit e05e5de7fae5bec79617e113916dac6631251156.

* README.arm-relocation: get relocated address in gdbBen Gardiner2011-05-121-0/+8
| | | | | | | | | | | | | | | When your emulator is connected at reset (or is used to load u-boot) it is possible to get the relocation address from the gd->relocaddr since gd is always in r8 (on ARM) it is addressable before the gdb has remapped symbols. Document this alternate method in-line with the original method written by Heiko Schocher.

* README.arm-relocation: get relocated address from bdinfoBen Gardiner2011-05-121-31/+22
| | | | | | | | | | | | | The bdinfo command prints the relocaddr on ARM as it does on PPC. Update the debugging instructions for arm relocation to reflect this fact rather than requiring that the user rebuild the u-boot image using -DDEBUG.

* Drop support for CONFIG_SYS_ARM_WITHOUT_RELOCWolfgang Denk2010-10-291-7/+0
| | | | | | | | | | | | | | | | 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 Denk2010-10-291-3/+2
| | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | ELF relocation tables generated with linker option -pie can be used to fixup code and data in a single loop at relocation, removing the need for manual fixups anywhere else in the code. Signed-off-by: Albert Aribaud <albert.aribaud@free.fr>

|/ / | | | | | | | | | | | | | | Commit 14d0a02a "Rename TEXT_BASE into CONFIG_SYS_TEXT_BASE" missed a few places, especially for boards that were added inbetween. Fix the remaining issues. Signed-off-by: Wolfgang Denk <wd@denx.de>
* / Rename TEXT_BASE into CONFIG_SYS_TEXT_BASEWolfgang Denk2010-10-181-6/+6
|/ | | | | | | | | | | | The change is currently needed to be able to remove the board configuration scripting from the top level Makefile and replace it by a simple, table driven script. Moving this configuration setting into the "CONFIG_*" name space is also desirable because it is needed if we ever should move forward to a Kconfig driven configuration system.

* ARM: implement relocation for ARM926Heiko Schocher2010-09-191-0/+23
| | | | | | | | | | | | | | | | | | | | | Change the implementation for arm926 to relocate the code to an arbitrary address in RAM. Adapt the TX25 (i.MX25), magnesium board to test the changes. On the tx25 board TEXT_BASE is set to the final relocation address to prevent one more copying of u-boot code when relocating.

* ARM: add relocation supportHeiko Schocher2010-09-191-0/+321
!! This breaks support for all arm boards !! To compile in old style, you must define CONFIG_SYS_ARM_WITHOUT_RELOC or you can compile with "CONFIG_SYS_ARM_WITHOUT_RELOC=1 ./MAKEALL board" !! This define will be removed soon, so convert your board to use relocation support Portions of this work were supported by funding from the CE Linux Forum.
