MIPS: Support dynamic I/O port base address

2016-02-01T21:13:25+00:00

The existing mips_io_port_base variable isn't suitable for use early
during boot since it will be stored in the .data section which may not
be writable pre-relocation. Fix this by moving the I/O port base address
into struct arch_global_data. In order to avoid adding this field for
all targets, make this dependant upon a new Kconfig entry
CONFIG_DYNAMIC_IO_PORT_BASE. Malta is the only board which sets a
non-zero I/O port base, so select this option only for Malta.

MIPS: unify cache initialization code

2015-01-29T11:55:01+00:00

The mips32 & mips64 cache initialization code differs only in that the
mips32 code supports reading the cache size from coprocessor 0 registers
at runtime. Move the more developed mips32 version to a common
arch/mips/lib/cache_init.S & remove the now-redundant mips64 version in
order to reduce duplication. The temporary registers used are shuffled
slightly in order to work for both mips32 & mips64 builds. The RA
register is defined differently to suit mips32 & mips64, but will be
removed by a later commit in the series after further cleanup.

MIPS: unify cache maintenance functions

2015-01-29T11:55:00+00:00

Move the more developed mips32 version of the cache maintenance
functions to a common arch/mips/lib/cache.c, in order to reduce
duplication between mips32 & mips64.

MIPS: remove board.c

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

After all MIPS boards are switched to generic-board, the
MIPS specific board.c can be removed.

MIPS: allow use of generic board

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

This patch allows MIPS boards to make use of generic board, replacing
arch/mips/lib/board.c with common/board_{f,r}.c and struct bd_info with
the asm-generic version.

MIPS: move mips_io_port_base out of board.c

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

Move the definition of this variable out of arch/mips/lib/board.c in
preparation for allowing use of generic board on MIPS, which will lead
to this file not being compiled.

kbuild: add CONFIG_ prefix to USE_PRIVATE_LIBGCC

2014-03-07T15:59:06+00:00

Before this commit, USE_PRIVATE_LIBGCC was defined in
arch-specific config.mk and referenced in
arch/$(ARCH)/lib/Makefile.

We are not happy about parsing config.mk again and again.
We have to keep the same behavior with a different way.

By adding "CONFIG_" prefix, this macro appears
in include/autoconf.mk, include/spl-autoconf.mk.
(And treating USE_PRIVATE_LIBGCC as CONFIG macro
is reasonable enough.)

Tegra SoC family defined USE_PRIVATE_LIBGCC as "yes"
in arch/arm/cpu/arm720t/tegra*/config.mk,
whereas did not define it in arch/arm/cpu/armv7/tegra*/config.mk.

It means Tegra enables PRIVATE_LIBGCC only for SPL.
We can describe the same behavior by adding

  #ifdef CONFIG_SPL_BUILD
  # define CONFIG_USE_PRIVATE_LIBGCC
  #endif

to include/configs/tegra-common.h.

MIPS: bootm: drop obsolete Qemu specific bootm implementation

2013-08-13T09:58:48+00:00

The Qemu specific bootm implementation was intended for a special
Qemu target in Linux kernel. But this target has been dropped in
v2.6.25-rc1 by commit 302922e5f6901eb6f29c58539631f71b3d9746b8

    Author: Ralf Baechle 
    Date:   Tue Jan 29 10:15:02 2008 +0000

    [MIPS] Qemu: Remove platform.

    The Qemu platform was originally implemented to have an easily supportable
    platform until Qemu reaches a state where it emulates a real world system.
    Since the latest release Qemu is capable of emulating the MIPSsim and
    Malta platforms, so this goal has been reached.  The Qemu plaform is also
    rather underfeatured so less useful than a Malta emulation.

Thus the special bootm implementation is obsolete by now and can be
dropped. The Qemu support in U-Boot is going to be replaced by MIPS Malta
board support.
