Since 3.10 the memory description for the Armada XP is 64 bits, to
allow to use more than 4GB of RAM with LPAE.
Unfortunately the ATAGS are 32 bits only.
If you use more than 4GB your only possibility is to disable
the ATAG support and only rely on the information written in
the dts: disable CONFIG_ARM_ATAG_DTB_COMPAT.

If you don't have more than 4GB of RAM then you can also apply this
patch: https://patchwork.kernel.org/patch/2566771/
It allows to use the ATAG and to keep the CONFIG_ARM_ATAG_DTB_COMPAT
option.
