[PATCH 0/3] [POWERPC] 4xx: Add support for AMCC 440EP Yosemite board

[Josh Boyer]

This small series of patches adds support for the AMCC 440EP Yosemite
evaluation board.  This is the newer evaluation board for PowerPC 440EP
chips, replacing the older Bamboo board.

This is just the initial round of patches, but they are functional.
Also of note is that while all for on-board UARTs are enumerated in the
DTS file, only two of them are usable on the board.  The other two have
their "status" property set to disabled.  If used in conjunction with
the of_device_is_disabled patches I just sent out, then devices for
those won't be created.  This is not required.
