Subject: [PATCH][PPC32] ev64260 update
Date: Tue, 25 Jan 2005 17:54:20 -0700 [thread overview]
Message-ID: <41F6EA3C.6060303@mvista.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 307 bytes --]
Hello again, Andrew.
This patch updates the support for the ev64260 eval platform from Marvell.
It:
- uses the platform_notify hook to update platform_data
- fixes a bug where a window to a device is disabled instead of enabled
- does some misc fixups
Signed-off-by: Mark A. Greer <mgreer@mvista•com>
