-----Original Message----- From: Fabio Estevam [mailto:festevam@gmail.com] Sent: Friday, May 11, 2012 9:08 AM To: u-boot@lists.denx.de Cc: sbabic@denx.de; Liu Hui-R64343; Estevam Fabio-R49496 Subject: [PATCH 3/3] mx53loco: Add LCD support
From: Fabio Estevam fabio.estevam@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.
