MIPS: unify CPU code in arch/mips/cpu/

2015-01-30T13:19:58+00:00

Unify and move code in arch/mips/cpu/mips[32|64]/ to arch/mips/cpu/.
The CPU specific config.mk files need to remain until
CONFIG_STANDALONE_LOAD_ADDR is converted to a global Kconfig symbol.

MIPS: add support for pre-relocation malloc

2015-01-21T13:07:23+00:00

Implement MIPS specific setup of the gd_t structure to support
pre-relocation malloc. If CONFIG_SYS_MALLOC_F_LEN is specified,
a memory area will be reserved after the initial stack area and
the gd->malloc_base pointer will be initialized.

After this patch the new driver model can be used on MIPS.

MIPS: add support for CONFIG_SYS_INIT_SP_ADDR

2015-01-21T13:07:16+00:00

Support the existing config option CONFIG_SYS_INIT_SP_ADDR on
MIPS. This allows to move the initial stack to other places
than the beginning of RAM.

MIPS: fix setup of initial stack frame

2014-11-27T15:20:37+00:00

To get correct stack walking and backtrace functionality in gdb,
registers fp and ra should be initialized before calling board_init_f
or board_init_r. Thus allocating stack space and zeroing it as it is
currently done in board.c becomes obsolete.

MIPS: add dynamic relocation support

2013-02-12T21:22:13+00:00

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.

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

2013-02-12T21:22:13+00:00

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.

MIPS: start.S: optimize BSS initialization

2013-02-12T21:22:13+00:00

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.
