MIPS: add dynamic relocation support

2013-02-12T21:22:13Z

The code handles relocation entries with the following relocation types only: mips32: R_MIPS_REL32 mips64: R_MIPS_REL+R_MIPS_64 xburst: R_MIPS_REL32 Other relocation entries are skipped without processing. The code must be extended if other relocation types must be supported. Add -pie to LDFLAGS_FINAL to generate the .rel.dyn fixup table, which will be applied to the relocated image before transferring control to it. The CONFIG_NEEDS_MANUAL_RELOC is not needed after the patch, so remove that as well. Signed-off-by: Gabor Juhos Signed-off-by: Daniel Schwierzeck

MIPS: start.S: use symbol __image_copy_end for U-Boot image relocation

2013-02-12T21:22:13Z

Use the newly introduced symbol __image_copy_end as end address for relocation of U-Boot image. This is needed for dynamic relocation added in later patches. This patch obsoletes the symbols uboot_end and uboot_end_data which are removed. Signed-off-by: Daniel Schwierzeck

MIPS: start.S: optimize BSS initialization

2013-02-12T21:22:13Z

Get the start and end address for clearing BSS from the newly introduced symbols __bss_start and __bss_end. After GOT is relocated, those symbols are already pointing to the correct addresses. Also optimize the loop by moving the address incrementation to the delay slot to avoid the initial sub instruction. Signed-off-by: Daniel Schwierzeck

MIPS: simplify relocated _G_O_T_ address calculation

2013-01-30T22:32:52Z

The difference between the address of the original and the relocated _GLOBAL_OFFSET_TABLE_ is always the same as the relocation offset. The relocation offset is already computed and it is available in the 's1/t6' register. Use that to adjust the relocated _G_O_T_ address, instead of calculating the offset again from the _gp value.

MIPS: start.S: don't save flush_cache parameters in advance

2013-01-27T15:40:15Z

Saving the parameters in advance unnecessarily complicates the code. The destination address is already saved in the 's2' register, and that register is not clobbered by the copy loop. The size of the copied data can be computed after the copy loop is done. Change the code to compute the size parameter right before calling flush_cache, and set the destination address parameter in the delay slot of the actuall call.
