[U-Boot] [PATCH v3 2/5] board support of arm64

From: David Feng fenghua@phytium.com.cn

This patch provide u-boot with arm64 support. Currently, it works on Foundation Model for armv8 or Fast Model for armv8.

Signed-off-by: David Feng fenghua@phytium.com.cn --- Changes for v3: - rewrite cache.S and exception.S that partly originated from linux kernel, so the license should be ok.
