PL310 is the L2$ controller from ARM used in many SoCs
including the Cortex-A9 based OMAP4430
Add support for some of the key PL310 operations
- Invalidate all
- Invalidate range
- Flush(clean & invalidate) all
- Flush range

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.

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

Turns out the documentation is wrong and doing "RAISE 1" does not result
in a software reset, only a core reset. So when the on-chip rom has a
functioning reset helper, use it.

We assumed that only a small set of compatiable strings would be needed
to find the PCIe device tree nodes to be fixed up. However on newer
platforms the simple rules no longer work. We need to allow specifying
the PCIe compatiable string for each individual SoC.
We introduce CONFIG_SYS_FSL_PCIE_COMPAT for this purpose and set it if
the default isn't sufficient.
