When going out of suspend to RAM, the Marvell EBU platforms go through the bootloader, which re-configures the DRAM controller. To achieve this, the bootloader executes a piece of code called the "DDR3 training code". It does some reads/writes to the memory to find out the optimal timings for the memory chip being used. This has the nasty side effect that the first 10 KB of each DRAM chip-select are overwritten by the bootloader when exiting the suspend to RAM state. Therefore, this commit implements the ->reserve() hook for the 'struct machine_desc' used on Armada XP, to reserve the 10 KB of each DRAM chip-select using the memblock API.
