* imx: fix exception vectors relocation in imx27Albert ARIBAUD2014-11-20-28/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 3ff46cc4 fixed exception vectors setting in the general ARM case, by either copying the exception and indirect vector tables to normal (0x00000000) or high (0xFFFF0000) vectors address, or setting VBAR to U-Boot's base if applicable. i.MX27 SoC is ARM926E-JS, thus has only normal and high options, but does not provide RAM at 0xFFFF0000 and has only ROM at 0x00000000; it is therefore not possible to move or change its exception vectors. Besides, i.MX27 ROM code does provide an indirect vectors table but at a non-standard address and with the reset and reserved vectors missing. Turn the current vector relocation code into a weak routine called after relocate_code from crt0, and add strong version for i.MX27.

* arm: relocate the exception vectorsGeorges Savoundararadj2014-10-29-0/+30
| | | | | | | | | | | This commit relocates the exception vectors. As ARM1176 and ARMv7 have the security extensions, it uses VBAR. For the other ARM processors, it copies the relocated exception vectors to the correct address: 0x00000000 or 0xFFFF0000.

* ARM,relocate: do not use r9Jeroen Hofstee2013-09-23-3/+3
| | | | | | | | | r9 is a platform-specific register in ARM EABI and not per definition a general purpose register. Do not use it while relocating so it can be used for gd. cc: Albert ARIBAUD <albert.u.boot@aribaud.net> Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>

| | | | | | | | | | | | | | | This change is only done where needed: some linker scripts may contain relocation symbols yet remain unchanged. __rel_dyn_start and __rel_dyn_end each requires its own output section; putting them in relocation sections changes their flags and breaks relocation.

* arm: factorize relocate_code routineAlbert ARIBAUD2013-05-30-0/+112
Replace all relocate_code routines from ARM start.S files with a single instance in file arch/arm/lib/relocate.S. For PXA, this requires moving the dcache unlocking code from within relocate_code into c_runtime_cpu_setup.
