[U-Boot] [PATCH 0/2] Add ccache support

[Marek Vasut]

These two patches make it easy to use ccache with U-Boot to speed up
iterative builds.

The results of building SoC MXS without ccache:
real    1m29.286s
user    7m1.972s
sys     0m46.668s

The results of building SoC MXS with ccache for the first time:
real    1m37.551s
user    7m23.632s
sys     0m59.332s

The results of building SoC MXS with ccache again:
real    0m41.968s
user    1m9.912s
sys     0m20.028s

The speedup is significant.

Marek Vasut (2):
  common: Add CCACHE variable to allow use of ccache
  common: Use separate dirs for each board for ccache
