Subject: [PATCH 2/4] i.mx53: voipac: Add board specific + flash header constructing code
Date: Tue,  1 Oct 2013 23:35:20 +0200	[thread overview]
Message-ID: <1380663322-25733-3-git-send-email-lisovy@gmail.com> (raw)
In-Reply-To: <1380663322-25733-1-git-send-email-lisovy@gmail.com>

In board.c enable UART0, NAND flash, Ethernet.
The DCD in flash_header.c is very similar (except for one line)
to that from freescale-mx53-smd
