This is a set of patches to add architecture support for the TI C6X
family of DSPs. A previous patch set for this architecture was posted
a while back:
http://lwn.net/Articles/442439/
This new set represents a lot of rework based on feedback from the
original posting. The major difference is a switch from static platform
devices to device tree support and a reworking of how the SoC and board
specific bits are partitioned. Also, all drivers have been removed from
the patch set so we can focus on just the arch bits. There is support for
four boards, each using a different SoC. Two of the SoCs contain multiple
cores but SMP is not supported due to lack of cache coherency.
