[Xen-devel] [PATCH] arm64: head: Fill image size

[Peng Fan <van.freenix@xxxxxxxxx>]

When booting xen from U-Boot, U-Boot will use the image size
info. Because this information is lacked in XEN image,U-Boot
assume the image size is 16MB to memmove, which will cost lots
time on simulation platform.
