Subject: [PATCH 01/07] ARM: mach-shmobile: Kota2 SCIFA2 and SMSC911X support
Date: Thu, 18 Aug 2011 05:44:07 +0000 [thread overview]
Message-ID: <20110818054407.23410.98641.sendpatchset@rxone.opensource.se> (raw)
From: Magnus Damm <damm@opensource.se>
Kota2 base board support including the on-chip SCIFA2
serial console and the on-board SMSC911X ethernet port.
The s73a0 SMP bits are also updated to include Kota2.
Signed-off-by: Magnus Damm <damm@opensource.se>
