[PATCH 6/6] ARM: Add relocatable binary support

For making the same binary executable on different SoCs which have different DRAM addresses we have to be independent of the compile time link address. This patch adds relocatable binary support for the ARM architecture. With this two new functions are available. relocate_to_current_adr will fixup

[PATCH 3/6] ARM: provide accessor functions for linker variables

With relocatable binaries the linker is not able to supply absolute addresses. These only get available when the relocation function is being run. Since for early initialization we need some variables before relocation, we supply them relatively to some known address in the binary. This means that

[PATCH 2/6] ARM: add early mmu cache flush function and use it in setup_c

Since recently with MMU_EARLY support it may happen that setup_c runs with data caches enabled, so we have to make sure the caches are flushed before we jump to the new binary. Signed-off-by: Sascha Hauer --- arch/arm/cpu/cache.c | 33 + arch/arm/cpu/setup
