MIPS port has two problems in timer routines. One is now we assume CFG_HZ
equals to CP0 counter frequency, but this is wrong. CFG_HZ has to be 1000
in the U-Boot system.
The other is we don't have a proper time management counter like timestamp
other ARCHs have. We need the 32-bit millisecond clock counter.
This patch introduces timestamp and CYCLES_PER_JIFFY. timestamp is a
32-bit non-overflowing CFG_HZ counter, and CYCLES_PER_JIFFY is the number
of calculated CP0 counter cycles in a CFG_HZ.
STRATEGY:
* Fix improper CFG_HZ value to have 1000
* Use CFG_MIPS_TIMER_FREQ for timer counter frequency, instead.
* timer_init: initialize timestamp and set up the first timer expiration.
Note that we don't need to initialize CP0 count/compare registers here
as they have been already zeroed out on the system reset. Leave them as
they are.
* get_timer: calculate how many timestamps have been passed, then return
base-relative timestamp. Make sure we can easily count missed timestamps
regardless of CP0 count/compare value.
* get_ticks: return the current timestamp, that is get_timer(0).
Most parts are from good old Linux v2.6.16 kernel.
v2:
- Remove FIXME comments as they turned out to be trivial.
- Use CP0 compare register as a global variable for expirelo.
- Kill a global variable 'cycles_per_jiffy'. Use #define CYCLES_PER_JIFFY
instead.

What we have to do is just to wait for given micro-seconds. No need to
take into account current time, get_timer and CFG_HZ.

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).
Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

Before new uImage code was merged, bootm code allowed for the kernel image to
get overwritten during decompresion. new uImage introduced a check for image
overwrites and refused to boot the image that got overwritten. This patch
restores the old behavior. It also adds a warning when the image overwriten is
a multi-image file, because in such case accessing componentes other than the
first one will fail.

This patch adds framework for dual format images. Format detection is added
and the bootm controll flow is updated to include cases for new FIT format
uImages.
When the legacy (image_header based) format is detected appropriate
legacy specific handling is invoked. For the new (FIT based) format uImages
dual boot framework has a minial support, that will only print out a
corresponding debug messages. Implementation of the FIT specific handling will
be added in following patches.

Architecture specific do_bootm_linux() routines share common
ramdisk image processing code. Move this code to a common
helper routine.
Signed-off-by: Marian Balakowicz <m8@semihalf.com>
Implementation of the do_bootm_linux() and other bootm helper routines is
architecture specific code. As such it resides in lib_<arch> directories
in files named <arch>_linux.c
This patch renames those files to a more clear and accurate
lib_<arch>/bootm.c form.
List of the renamed files:
lib_arm/armlinux.c -> lib_arm/bootm.c
lib_avr32/avr32_linux.c -> lib_avr32/bootm.c
lib_blackfin/bf533_linux.c -> lib_blackfin/bootm.c

Although mips_io_port_base is currently a part of IDE command, it is quite
fundamental for MIPS I/O port access such as in[bwl] and out[bwl]. So move
it to MIPS general part, and introduce `set_io_port_base()' from Linux.
This patch is triggered by multiple definition of `mips_io_port_base' build
error on gth2 (and tb0229 also needs this fix.)

After:

Modifications are based on the linux kernel approach and
support two use cases:
1) Add O= to the make command line
'make O=/tmp/build all'
2) Set environement variable BUILD_DIR to point to the desired location
'export BUILD_DIR=/tmp/build'
'make'
The second approach can also be used with a MAKEALL script
'export BUILD_DIR=/tmp/build'
'./MAKEALL'
Command line 'O=' setting overrides BUILD_DIR environent variable.
When none of the above methods is used the local build is performed and
the object files are placed in the source directory.
