From 7d91fcfcb91dde7bc4586154942862c1724b3519 Mon Sep 17 00:00:00 2001 From: Takanari Hayama Date: Mon, 22 Dec 2008 11:05:03 +0900 Subject: sh: add UIO support for JPU on SH7722. 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.
