[U-Boot] [PATCH V4 3/3] Add support for the LaCie ED Mini V2 board
Albert Aribaud
albert.aribaud at free.fr
Sun Jan 10 17:03:48 CET 2010
This patch adds support for the LaCie ED Mini V2 product
which is based on the Marvell Orion5x SoC.
Current support is limited to console and Flash.
Flash support uses CONFIG_FLASH_CFI_LEGACY as the
Macronix MX29LV400 used on ED Mini V2 is not CFI
compliant (mixes 16 and 8 bit behaviors).
