[ARM] pxa: add basic support for Voipac PXA270 SBC
This patch adds basic support for the Voipac PXA270 SBC. The device consists of the following hardware: - PXA270 @ 520 MHz - 256MB RAM (sparsemem, 2*128MB regions) - 64MB NOR flash - 640x480 LCD - Ports: 2xUHC, 1xUDC, 1xPCMCIA, VGA, FFUART, 2xPS2, Speaker, MIC Signed-off-by: Marek Vasut <marek.vasut@gmail.com> Signed-off-by: Eric Miao <eric.y.miao@gmail.com>
