From b2c6561605da4802886cafe96432b8e2968e9edc Mon Sep 17 00:00:00 2001 From: Andrew Victor Date: Thu, 8 Feb 2007 09:42:40 +0100 Subject: [PATCH] [ARM] 4145/2: AT91: Add support for AT91SAM9263 processor Add support for the Atmel AT91SAM9263 processor. It is similar to the AT91SAM9260 but with more integrated peripherals, 5 GPIO banks, etc. Original patch from Nicolas Ferre.
