This summary, and the various changelogs need to be updated to be more
descriptive, particularily in the usage of the words 'device' and
'driver'.

The changelog terminology used is confusing, and sometimes wrong.  What
is actually being done is splitting up the current DMA library into 3
parts: a common platform_driver (plat-omap/dma.c), OMAP1 device code
(mach-omap1/dma.c) and OMAP2+ device code (mach-omap2/dma.c)

Thanks for the thorough build and test report.   Very nice.
