This prevents the DMA API debugging from running out of entries right
away on boot. Defines 4096 entries by default, which while a bit on the
heavy side, ought to leave enough breathing room for some time.

Split pages returned by dma_alloc_coherent() and make sure
we free them one by one.

sh: select memchunk size using kernel cmdline2008-08-11T11:17:55+00:00Magnus Dammdamm@igel.co.jp2008-08-11T06:13:24+00:00urn:sha1:0c13bf1e7c98668ce69eaedd215ec32f9e1361ae
Allow user to pass parameters on kernel command line to override
default size for physically contiguous memory buffers. The default
VPU buffer size is too small for VGA harware encoding, but instead
of just bumping up the number we allow the user to override the
default size using the command line. Supports SuperH Mobile hardware
blocks such as VEU, VPU and CEU.

This patch adds physically contiguous memory chunks to the UIO devices.
The same strategy can be used in the future for the CEU as well.
