* Drop support for CONFIG_SYS_ARM_WITHOUT_RELOCWolfgang Denk2010-10-29-1/+1
| | | | | | | | | | | | | | | | 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>
* Rename TEXT_BASE: fix merge conflictsWolfgang Denk2010-10-18-1/+2
| | | | | | | | 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 Denk2010-10-18-1/+1
| | | | | | | | | | | | 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: add relocation supportHeiko Schocher2010-09-19-0/+7
| | | | | | | | | | | | | | | | | | | !! 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.

* nand_spl: Fix cmd_ctrl usage in nand_boot.c.Scott Wood2009-07-07-7/+11
| | | | | | | | | | | | | | | | When adding large page NAND support to this file, I had a misunderstanding about the exact semantics of NAND_CTRL_CHANGE (which isn't documented anywhere I can find) -- it is apparently just a hint to drivers, which aren't required to preserve the old value for subsequent non-"change" invocations. This change makes nand_boot.c no longer assume this. Note that this happened to work by chance with some NAND drivers, which don't preserve the value, but treat 0 equivalently to NAND_CTRL_ALE. I don't have hardware to test this, so any testing is appreciated. Signed-off-by: Scott Wood <scottwood@freescale.com>
* nand_spl: read environment early, when booting from NAND using nand_splGuennadi Liakhovetski2009-07-07-0/+10
| | | | | | | | | | | | Currently, when booting from NAND using nand_spl, in the beginning the default environment is used until later in boot process the dynamic environment is read out. This way environment variables that must be interpreted early, like the baudrate or "silent", cannot be modified dynamically and remain at their default values. Fix this problem by reading out main and redundand (if used) copies of the environment in the nand_spl code.

* nand_spl: Support page-aligned read in nand_load, use chipselectGuennadi Liakhovetski2008-08-12-10/+20
| | | | | | | | | Supporting page-aligned reads doesn't incure any sinificant overhead, just a small change in the algorithm. Also replace in_8 with readb, since there is no in_8 on ARM. Signed-off-by: Guennadi Liakhovetski <lg@denx.de> Signed-off-by: Scott Wood <scottwood@freescale.com>

* NAND boot: MPC8313ERDB supportScott Wood2008-08-12-2/+2
| | | | | | | | | Note that with older board revisions, NAND boot may only work after a power-on reset, and not after a warm reset. I don't have a newer board to test on; if you have a board with a 33MHz crystal, please let me know if it works after a warm reset. Signed-off-by: Scott Wood <scottwood@freescale.com>
* NAND: Update nand_spl driver to match updated nand subsystemStefan Roese2008-08-12-15/+19
| | | | | | | | | This patch changes the NAND booting driver nand_spl/nand_boot.c to match the new infrastructure from the updated NAND subsystem. This NAND subsystem was recently synced again with the Linux 2.6.22 MTD/NAND subsystem. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx/NAND_SPL: Consolidate 405 and 440 NAND booting code in start.SStefan Roese2008-06-03-6/+5
| | | | | | | | | | | | | | | | | This patch consolidates the 405 and 440 parts of the NAND booting code selected via CONFIG_NAND_SPL. Now common code is used to initialize the SDRAM by calling initdram() and to "copy/relocate" to SDRAM/OCM/etc. Only *after* running from this location, nand_boot() is called. Please note that the initsdram() call is now moved from nand_boot.c to start.S. I experienced problems with some boards like Kilauea (405EX), which don't have internal SRAM (OCM) and relocation needs to be done to SDRAM before the NAND controller can get accessed. When initdram() is called later on in nand_boot(), this can lead to problems with variables in the bss sections like nand_ecc_pos[].
