a separate branch up until this point. The interfaces are complete
and most platforms have been verified (still a little to be done
however). (2015-05-02)
* arch/arm/src/lpc31xx/lpc31_ehci.c, chip.h, sama5/sam_ehci.c, and
chip.h: Fix cache related problem in LPC31 and SAMA5Dx EHCI drivers.
All buffers are now aligned with the cache line size in both starting
address and in length. This cause major problems in unlucky builds
where the USB host buffers where unaligned and abbutting other data.
The cache flush and invalidate operations could be subverted by
accesses to adjacent data or could have unexpected side effects. This
bug has been in the ECHI drivers forever, but was only revealed due to
unlucky memory allocations during the integration of the hub feature
(2015-05-03).
