[U-Boot] [PATCH 2/2] add support of arm/pxa270 board made by voipac [rev 2]
Mikhail Kshevetskiy
mikhail.kshevetskiy at gmail.com
Wed Apr 7 13:49:36 CEST 2010
This patch is based on custom u-boot-1.1.2 version produced by voipac
(http://www.voipac.com) and board/trizepsiv files from current u-boot.
Up to now only PXA270 DIMM module with NOR flash is tested.
v2: code style was improved
