Subject: [U-Boot] [PATCH RFC] at91sam9/at91cap: move common initialisation to cpu
Date: Fri, 7 Nov 2008 20:38:26 +0100 [thread overview]
Message-ID: <1226086706-5419-1-git-send-email-plagnioj@jcrosoft.com> (raw)
Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>
---
The idea is to reduce common code initialisation which is actually in board.
as done on afeb9260 and Ronetix eval board for 9260 & 9263
Best Regards,
J.
