>Subject: [PATCH 3/3] mx53loco: Add LCD support
>
>From: Fabio Estevam <fabio.este...@freescale.com>
>
>Add support for CLAA07LC0ACW LCD that connects to the mx53loco board.
>
>Configure the board to show the Linux logo on the LCD.
>
>Also increase the size of CONFIG_SYS_MALLOC_LEN variable to take into
>account the framebuffer usage.
