C6X: memory management and DMA support2011-10-06T23:47:37+00:00Aurelien Jacquiota-jacquiot@ti.com2011-10-04T16:17:19+00:00urn:sha1:14aa7e8bf6d84c9a42c48e7f93472d830f694b1e
Original port to early 2.6 kernel using TI COFF toolchain.
Brought up to date by Mark Salter <msalter@redhat.com>
The C6X architecture currently lacks an MMU so memory management is relatively
simple. There is no bus snooping between L2 and main memory but coherent DMA
memory is supported by making regions of main memory uncached. If such a region
is desired, it can be specified on the commandline with a "memdma=" argument.
