+ARM System emulator
+-------------------
+
+Use the executable ``qemu-system-arm`` to simulate a ARM machine. The
+ARM Integrator/CP board is emulated with the following devices:
+
+-  ARM926E, ARM1026E, ARM946E, ARM1136 or Cortex-A8 CPU
+
+-  Two PL011 UARTs
+
+-  SMC 91c111 Ethernet adapter
+
+-  PL110 LCD controller
+
+-  PL050 KMI with PS/2 keyboard and mouse.
+
+-  PL181 MultiMedia Card Interface with SD card.
+
+The ARM Versatile baseboard is emulated with the following devices:
+
+-  ARM926E, ARM1136 or Cortex-A8 CPU
+
+-  PL190 Vectored Interrupt Controller
+
+-  Four PL011 UARTs
+
+-  SMC 91c111 Ethernet adapter
+
+-  PL110 LCD controller
+
+-  PL050 KMI with PS/2 keyboard and mouse.
+
+-  PCI host bridge. Note the emulated PCI bridge only provides access
+   to PCI memory space. It does not provide access to PCI IO space. This
+   means some devices (eg. ne2k_pci NIC) are not usable, and others (eg.
+   rtl8139 NIC) are only usable when the guest drivers use the memory
+   mapped control registers.
+
+-  PCI OHCI USB controller.
+
+-  LSI53C895A PCI SCSI Host Bus Adapter with hard disk and CD-ROM
+   devices.
+
+-  PL181 MultiMedia Card Interface with SD card.
+
+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.
