+Subject: [PATCH] aspeed: Limit bootm memory
+
+This ensures u-boot places the kernel, device tree and initrd at an
+address that is accessible by the Linux early boot code.
+
+Without this, when booting with FIT the device tree is placed at the end
+of RAM which is not mapped on the AST2600 EVB which contains 2GB of RAM.
+
+Signed-off-by: Joel Stanley <joel@jms.id.au>
