Completely replaces the patch [PATCH][ARM] Move ARM supplied dev boards to new board/armltd directory submitted Tue, 18 Mar 2008.
This patch will allow code common to all ARM supplied development boards to be shared.
This patch is also available for test from git://linux-arm.org/u-boot-armdev.git as branch 080312_move
This patch is made against u-boot commit commit fdeb932b1c8a3b615463995c3452d30ee0b12a33 Merge: 3515fd1... 1f2a997... Author: Wolfgang Denk wd@denx.de Date: Tue Mar 18 22:15:58 2008 +0100
