2c451f7831 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
  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

9aeab10bd4 Blackfin: use on-chip reset func with newer parts

8f29084a4f powerpc/fsl_pci: Fix device tree fixups for newer platforms
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.
