[U-Boot] [PATCH v7 2/2] arm: A320: Add support for Faraday A320 evaluation board

Po-Yu Chuang ratbert.chuang at gmail.com
Wed Sep 23 09:53:04 CEST 2009


This patch adds support for A320 evaluation board from Faraday. This board
uses FA526 processor by default and has 512kB and 32MB NOR flash, 64M RAM.
FA526 is an ARMv4 processor and uses the ARM920T source in this patch.
