sh: SH-2007 board support.
This patch series adds support for ITO Co., Ltd.'s SH-2007 reference platform (A PC-104 based SH7780 platform). This is a direct port of the out-of-tree board support from the vendor's kernel, originally located at: http://ms-n.org/sh-linux/kernel/ More information on the board and the vendor can be obtained from the vendor's site at: http://www.itonet.co.jp/ Presently supported peripherals are CF and ethernet, with support for the on-board IDE still pending further testing.
