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.

kbuild: use SoC-specific CONFIG to descend into SoC directory

2014-11-23T11:49:02+00:00

Use "obj-$(CONFIG_FOO) += foo/" where it is possible.

kbuild: Descend into SOC directory from CPU directory

2014-11-23T11:49:02+00:00

Some CPUs of some architectures have SOC directories.
At present, the build system directly descends into SOC directories
from the top Makefile, but it should generally descend into each
directory from its parent directory.

include: move various macros to include/linux/kernel.h

2014-11-20T16:28:25+00:00

U-Boot has imported various utility macros from Linux
scattering them to various places without consistency.

In include/common.h are min, max, min3, max3, ARRAY_SIZE, ALIGN,
container_of, DIV_ROUND_UP, etc.
In include/linux/compat.h are min_t, max_t, round_up, round_down,
etc.
We also have duplicated defines of min_t in some *.c files.

Moreover, we are suffering from too cluttered include/common.h.

This commit moves various macros that originate in
include/linux/kernel.h of Linux to their original position.

Note:
This commit simply moves the macros; the macros roundup,
min, max, min2, max3, ARRAY_SIZE are different
from those of Linux at this point.

MIPS: add .padding section to linker script

2014-11-01T17:18:05+00:00

Commit 79fd7e649e287228a1445820a72f7dd33baedb96

    MIPS: always keep all sections in u-boot ELF binary.

    Always keep all sections in u-boot ELF binary. Move all unneeded
    sections after _end to avoid allocating space in the final binary.
    Also remove .deadcode section which is now obsolete.

removed section .deadcode because the original symptoms were not
visible anymore. Unfortuneatly the binutils bug still exists.

The size of .rel.dyn section is often bigger than needed for all
entries. But objcopy only allocates space as much as required for all
reloc entries. Thus there is a gap between the last entry and
__rel_dyn_end in u-boot.bin. If u-boot is booted from RAM (e.g. in
SPL scenarios) that area could contain garbage data which could lead
to CPU exceptions during relocation.

MIPS: drop incaip board

2014-04-20T11:16:43+00:00

This is dead hardware and no one is interested in making the
necessary changes for upcoming features like generic board or
driver model.

MIPS: define __init_end in u-boot.lds

2014-04-20T11:16:43+00:00

The generic board code uses the __init_end symbol to calculate
monitor_flash_len. Define said symbol for MIPS, equivalent to
__image_copy_end which is used for the same purpose in
arch/mips/lib/board.c.

MIPS: stub interrupt_init function

2014-04-20T11:16:42+00:00

interrupt_init is called unconditionally by the generic board code.
Define a stub for it on MIPS like the enable & disable functions.

mips: xburst: remove remainders of dead board

2014-04-20T11:16:42+00:00

Commit 54e458de deleted qi_lb60 board support
because of the incompatible license issue.

There is no board with XBurst CPU.
