# Arm Realview boards (`realview-eb`, `realview-eb-mpcore`, `realview-pb-a8`, `realview-pbx-a9`)

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 emulated:

- ARM926E, ARM1136, ARM11MPCore, Cortex-A8 or Cortex-A9 MPCore CPU

- Arm AMBA Generic/Distributed Interrupt Controller

- Four PL011 UARTs

- SMC 91c111 or SMSC LAN9118 Ethernet adapter

- PL110 LCD controller

- PL050 KMI with PS/2 keyboard and mouse

- PCI host bridge

- PCI OHCI USB controller

- LSI53C895A PCI SCSI Host Bus Adapter with hard disk and CD-ROM devices

- PL181 MultiMedia Card Interface with SD card.
