Checkpatch.pl complains about the volatile qualifier in calls to
get_ram_size(). Remove this qualifier in the prototype and in the
calls where it is useless, and leave it only in the function body
where it is needed.

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.

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
