-The ARM RealView Emulation/Platform baseboard is emulated with the following
-devices:
+Several variants of the ARM RealView baseboard are emulated,
+including the EB, PB-A8 and PBX-A9. Due to interactions with the
+bootloader, only certain Linux kernel configurations work out
+of the box on these boards.
+
+Kernels for the PB-A8 board should have CONFIG_REALVIEW_HIGH_PHYS_OFFSET
+enabled in the kernel, and expect 512M RAM. Kernels for The PBX-A9 board
+should have CONFIG_SPARSEMEM enabled, CONFIG_REALVIEW_HIGH_PHYS_OFFSET
+disabled and expect 1024M RAM.
+
+The following devices are emuilated:
