OMAP[34]: fix broken timer
As implemented now the timer used to implement __udelay counts
to 0xffffffff and then gets stuck there because the the programmed
reload value is 0xffffffff. This value is not only wrong but
illegal according to the reference manual.
One can reproduce the bug by leaving a board at the u-boot prompt
for sometime then issuing a sleep command. The sleep will hang
forever.
The timer is a count up timer that reloads as it rolls over
from 0xffffffff so the correct load value is 0.
Change TIMER_LOAD_VAL from 0xffffffff to 0 and introduce
a new constant called TIMER_OVERFLOW_VAL set to 0xffffffff.

arm: minor fixes for cache and mmu handling
1. make sure that page table setup is not done multiple times
2. flush_dcache_all() is more appropriate while disabling cache
than a range flush on the entire memory(flush_cache())
Provide a default implementation for flush_dcache_all()
for backward compatibility and to avoid build issues.

armv7: cache maintenance operations for armv7
- Add a framework for layered cache maintenance
- separate out SOC specific outer cache maintenance from
maintenance of caches known to CPU
- Add generic ARMv7 cache maintenance operations that affect all

opertions will affect both L1 and L2 caches. In Cortex-A9
these will affect only L1 cache

NAND: Add 16bit NAND support for the NDFC
This patch adds support for 16 bit NAND devices attached to the
NDFC on ppc4xx processors. Two config entries were added:
CONFIG_SYS_NDFC_16 - Setting this tells the NDFC that a
16 bit device is attached.
CONFIG_SYS_NDFC_EBC0_CFG - This is for the External Bus
Controller configuration register.
Also, a new ndfc_read_byte() function was added which does not
first convert the data to little endian.
The NAND SPL was also modified to do 16bit bad block testing
when a 16 bit chip is being used.

i might be thinking of a different env_embedded situation. a different
