Fix ARM based DaVinci DM644x timer overflow handling and cleanup timer code.
Changes:
- Remove *_masked() functions as noted by Wolfgang
- Adapt register naming to recent TI spec (sprue26, March 2007)
- Fix reset_timer() handling
- As reported by Pieter [1] the overflow fix introduced a delay of factor 16 (e.g 2 seconds became 32). While the overflow fix is basically okay, it missed to divide udelay by 16, too. Fix this.

- Remove software division of timer count value (DIV(x) macro) and do it in hardware (TIM_CLK_DIV).
Many thanks to Troy Kisky <troy.kisky@boundarydevices.com> and Pieter Voorthuijsen <pieter.voorthuijsen@Prodrive.nl> for the hints & testing!
Patch is compile tested with davinci_dvevm & sonata & schmoogie configuration and tested by Pieter on DaVinci EVM hardware.

Limit the rate of h/w watch-dog triggering on the LWMON5 board by
the CONFIG_WD_MAX_RATE value.
Note that an earlier version of this patch which used microseconds
instead of ticks dis not work. The problem was that we used
usec2ticks() to convert microseconds into ticks. usec2ticks() uses
get_tbclk(), which in turn calls get_sys_info(). It turns out that
this function does a lot of prolonged operations (like divisions)
which take too much time so we do not trigger the watchdog in time,
and it resets the system.

Introduce the new logical option CONFIG_HAS_POST which is set when the
platform has CONFIG_POST set. Use CONFIG_HAS_POST in the post/ Makefiles
to determine should the POST libs be compiled for the selected target
platform, or not.
To avoid breaking u-boot linking process, the empty post/libpost.a file is
created for platforms which do not have POSTs.

This patch fixes the Canyonlands and Glacier default environment to better
fit to the arch/powerpc device-tree kernels. The variables dealing with
arch/ppc booting are removed, since these boards are supported only in
arch/powerpc. Glacier uses the same config file as Canyonlands.
Also, the Glacier now uses non-FPU rootpath, since 460GT has no FPU.

dcache_enable() was missing for 440 and the patch
017e9b7925 ["allow ports to override bootelf
"] behavior uses this function.
Note: Currently the cache handling functions like
d/icache_disable/enable() are NOP's on 440. This may be changed in the
future.

This patch correctly sets the oobavail variable
and fixes a bug where the oob data was not valid when
there where multiple groups in oobfree.
First segment fixes a typo
Second segment fixes a bug where oob data may be copied incorrectly.
Third segment adds an error message when exiting due to write protect.
Forth segment fixes a bug where oobavail may be set incorrectly.

This patch assigns the correct EBC clock for 405GP(r) CPUs
to PPC4xx_SYS_INFO structure. Without this patch U-Boot
uses an uninitialized EBC clock in its startup message.

Some 85xx chips use CCB as the base clock for the I2C. Some use CCB/2, and
some use CCB/3. There is no pattern that can be used to determine which
chips use which frequency, so the only way to determine is to look up the
actual SOC designation and use the right value for that SOC.
Update immap_85xx.h to include the GUTS PORDEVSR2 register.

This patch allows U-Boot to use buffered writes to the Spansion NOR
flash installed on this board, and eliminates long delays in network
transfers after the board startup.
Also modify flash layout to embed main and redundant environment
blocks in the U-Boot image.

Currently U-Boot crashes on sequoia board in CPU POST if
cache is enabled (CONFIG_4xx_DCACHE defined). The cache
won't be disabled by change_tlb before CPU POST because
there is an insufficient adress range check since
CFG_MEM_TOP_HIDE was introduced. This patch tries to fix
this problem.

Current assembler codes are inconsistent in the way of register jump
instruction usage; some use jr, some use j. Of course GNU as allows both
usages, but as can be expected from `Jump Register' the mnemonic `jr' is
more intuitive than `j'. For example, Linux doesn't have `j <reg>' usage
at all.

This is an SPI driver for i.MX and MXC based SoCs from Freescale. So far
only implemented and tested on i.MX31, can with a modified register layout
and definitions be used for i.MX27, I think, MXC CPUs have similar SPI
controllers too.

Split the arch-specific logic out of the common go code and into a dedicated
weak function called do_go_exec() that lives in cpu directories. This will
need review from i386/nios people to make sure I didn't break them.
Change the bootelf setup function into a dedicated weak function called
do_bootelf_exec. This way ports can control the behavior however they
like before/after calling the ELF entry point.

This patch removes the board dependent parts from
"drivers/mtd/dataflash.c".
Each board relying on this, will have the appropriate
code in a new file, "partition.c" in the board directory.
board Makefiles updated to use the file.
The dataflash partitions are aligned on sector/page boundaries.
The CONFIG_NEW_DF_PARTITION was used to create named partitions
This is now the default operation, and the CONFIG variable is removed.

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.
