This patch enables the new clock features from arm920t/at91/clock.c. This
is an required step to get at91rm9200_usart replaced by atmel_usart driver.

Replace the cache related CONFIG flags with more meaningful
names. Following are the changes:
CONFIG_L2_OFF -> CONFIG_SYS_L2CACHE_OFF
CONFIG_SYS_NO_ICACHE -> CONFIG_SYS_ICACHE_OFF
CONFIG_SYS_NO_DCACHE -> CONFIG_SYS_DCACHE_OFF
Signed-off-by: Aneesh V <aneesh@ti.com>
V2:
* Changed CONFIG_L2_OFF -> CONFIG_SYS_NO_L2CACHE
V4:
* Changed all three flags to the final names suggested as above
and accordingly changed the commit message
- 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
caches known to ARMv7 CPUs. For instance in Cortex-A8 these
opertions will affect both L1 and L2 caches. In Cortex-A9
these will affect only L1 cache
- D-cache operations supported:
- Invalidate entire D-cache
- Invalidate D-cache range
- Flush(clean & invalidate) entire D-cache
- Flush D-cache range
- I-cache operations supported:
- Invalidate entire I-cache
- Add maintenance functions for TLB, branch predictor array etc.
- Enable -march=armv7-a so that armv7 assembly instructions can be
used

Add a flag to nand_read_skip_bad() such that if true, any trailing
pages in an eraseblock whose contents are entirely 0xff will be
dropped.
The implementation is via a new drop_ffs() function which is
based on the function of the same name from the ubiformat
utility by Artem Bityutskiy.
This is as-per the reccomendations of the UBI FAQ [1]

When specified in the flags argument of nand_write, WITH_YAFFS_OOB causes an
operation which is mutually exclusive with the 'usual' way of writing.
Add a check that client code does not specify WITH_YAFFS_OOB along with any
other flags and add a comment indicating that the WITH_YAFFS_OOB flag should
not be mixed with other flags.

In a future commit the behaviour of nand_write_skip_bad()
will be further extended.
Convert the only flag currently passed to the nand_write_
skip_bad() function to a bitfield of only one allocated
member. This should avoid an explosion of int's at the
end of the parameter list or the ambiguous calls like
nand_write_skip_bad(info, offset, len, buf, 0, 1, 1);
nand_write_skip_bad(info, offset, len, buf, 0, 1, 0);
Instead there will be:
nand_write_skip_bad(info, offset, len, buf, WITH_YAFFS_OOB |
WITH_OTHER);
