From: Fabio Estevam fabio.estevam@freescale.com
Add support for the Seiko 4.3'' WVGA panel on mx53loco.
By default, the CLAA WVGA panel is selected.
In order to support the Seiko panel, the enviroment variable 'panel' must be set to 'seiko'.
Signed-off-by: Fabio Estevam fabio.estevam@freescale.com --- Changes since v1: - Allow a single binary to support both CLAA and Seiko panels
