Subject: [PATCH] add UIO support for JPU.
Date: Mon, 22 Dec 2008 02:05:03 +0000 [thread overview]
Message-ID: <494EF5CF.1030901@igel.co.jp> (raw)
Add JPU support on Migo-R via UIO. This make use of Magnus's
generic UIO platform driver. Chunk of contiguous memory to hold
intermediate image and compressed data during encode and decode.
