4Several variants of the Arm RealView baseboard are emulated, including
5the EB, PB-A8 and PBX-A9. Due to interactions with the bootloader, only
6certain Linux kernel configurations work out of the box on these boards.
7
8Kernels for the PB-A8 board should have CONFIG_REALVIEW_HIGH_PHYS_OFFSET
9enabled in the kernel, and expect 512M RAM. Kernels for The PBX-A9 board
10should have CONFIG_SPARSEMEM enabled, CONFIG_REALVIEW_HIGH_PHYS_OFFSET
11disabled and expect 1024M RAM.
