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: handle mips64 ST0_KX bit in mips32 start.S

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

In preparation for sharing a single copy of start.S between mips32 &
mips64, handle setting the KX bit of the cop0 Status register when the
mips32 start.S is built for mips64.

MIPS: handle mips64 relocs in mips32 start.S

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

In preparation for sharing a single copy of start.S between mips32 &
mips64, handle mips64 relocations in the mips32 start.S when built for
mips64.

MIPS: use asm.h macros in mips32 start.S

2015-01-30T13:19:57+00:00

Where the mips32 & mips64 implementations of start.S differ in terms of
access sizes & offsets, use the appropriate macros from asm.h to
abstract those differences away. This is in preparation for sharing a
single copy of start.S between mips32 & mips64.

The exception to this is loads of immediates to be written to the cop0
Config register, which is a 32bit register on mips64 and therefore
constants written to it can be loaded as such.

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.

qemu-malta: rename to just "malta"

2013-11-09T16:21:01+00:00

This is in preparation for adapting this board to function correctly on
a physical MIPS Malta board. The board is moved into an "imgtec" vendor
directory at the same time in order to ready us for any other boards
supported by Imagination in the future.

MIPS: mips32/start.S: rework relocation info check

2013-07-24T13:51:05+00:00

Make it similar to the code in mips64/start.S, in order to
allow further unifications.

MIPS: mips32/start.S: use t8 register for dynamic relocation

2013-07-24T13:51:05+00:00

Synchronize the code with mips64/start.S, in order to
allow further unifications.
