RTC: Fix month offset by one problem in M41T62 RTC driver
This patch fixes a problem with the month being read and written
incorrectly (offset by one). This only gets visible by also using
the Linux driver (rtc-m41t80).

Fix calculation of I2C clock for some 86xx chips
Some 86xx chips use CCB as the base clock for the I2C, and others used CCB/2.
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.
The ethernet hang is caused by receiving buffer in DRAM is not
yet ready due to access cycles require longer time in DRAM.
Relocate DMA buffer descriptors from DRAM to internal SRAM.

Fix warnings while compiling net/net.c for MPC8610HPCD board
MPC8610HPCD board adds -O2 gcc option to PLATFORM_CPPFLAGS
causing overriding default -Os option. New gcc (ver. 4.2.2)
produces warnings while compiling net/net.c file with -O2
option. The patch is an attempt to fix this.
A few boards (like netstar and voiceblue) need some libraries for
building; however, the board Makefile does not contain any such
dependencies which may cause problems with parallel builds. Adding
such dependencies is difficult as we would also have to provide build
rules, which already exist in the respective library Makefiles.
To solve this, we make sure that all libraries get built before the
board code.

85xx: Add -mno-spe to e500/85xx builds
Newer gcc's might be configured to enable autovectorization by default.
If we happen to build with one of those compilers we will get SPE
instructions in random code.
-mno-spe disables the compiler for automatically generating SPE
instructions without our knowledge.

85xx: Additional fixes and cleanup of MP code
* adjust __spin_table alignment to match ePAPR v0.94 spec
* loop over all cpus when determing who is up. This fixes an issue if
the "boot cpu" isn't core0. The "boot cpu" will already be in the
cpu_up_mask so there is no harm
* Added some protection in the code to ensure proper behavior. These
changes are explicitly needed but don't hurt:
- Added eieio to ensure the "hot word" of the table is written after
all other table updates have occurred.
- Added isync to ensure we don't prefetch loading of table entries
until we a released

ppc flush_cache: add watch-dog triggering into the loops.
Some boards (e.g. lwmon5) need rather a frequent watch-dog
kicking. Since the time it takes for the flush_cache() function
to complete its job depends on the size of data being flushed, one
may encounter watch-dog resets on such boards when, for example,
download big files over ethernet.

ppc4xx: Change ECC initialization on lwmon5 to use clean_dcache_range()
As it seems the "old" ECC initialization routine by using dflush() didn't
write all lines in the dcache back to memory on lwmon5. This could lead
to ECC error upon Linux booting. This patch changes the program_ecc()
routine to now use clean_dcache_range() instead of dflush().
clean_dcache_range() uses dcbst which is exactly what we want in this
case.
Since dflush() is known is cause problems, this routine will be
removed completely and replaced by clean_dcache_range() with an
additional patch.

Currently the timeout waiting for an ARP reply is hard set to 5 seconds.
On i.MX31ADS due to a hardware "strangeness" up to four first IP packets
to the boards get lost, which typically are ARP replies. By configuring
the timeout to a lower value we significantly improve the first network
transfer time on this board. The timeout is specified in milliseconds,
later internally it is converted to deciseconds, because it has to be
converted to hardware ticks, and CFG_HZ ranges from 900 to 27000000 on
different boards.

This patch adds a configurable flash auto protection list that can be used
to make U-Boot protect flash regions in flash_init().
The idea has been discussed on the u-boot mailing list starting
on Nov 18th, 2007.
Even this patch brings a new feature it is used as a bugfix for 4xx
platforms where flash_init() does not completely protect the
monitor's flash range in all situations.
U-Boot protects the flash range from CFG_MONITOR_BASE to
(CFG_MONITOR_BASE + monitor_flash_len - 1) by default. This does not
include the reset vector at 0xfffffffc.

Add support for calculating hashes with watchdog triggering
Implement watchodg-aware variants of hash calculation functions:
- crc32_wd()
- md5_wd()
- sha1_csum_wd()
The above functions calculate the hash of the input buffer in chunks,
triggering the watchdog after processing each chunk. The chunk size
is given as a function call parameter.
As suggested by Wolfgang Denk:
- image printing functions:
- remove wrappers
- remove indentation prefix from functions' signatures
- merge getenv_verify and getenv_autostart into one parametrized function
