Adrien Destugues 5b172de123 Update some docs for the ARM port.

* Add info on Allwinner A10 SOCs, which may be a worthwile target.
* Add info about the Linaro QEmu for emulating the BeagleBoard.
* Add more TODOs for PM aftermath.

TODO: This is a WIP

Hardware information (Rev A5A)

ARMv7 Architecture
Sitara AM3359AZCZ100 Cortex-A8 CPU @ 1 Ghz
PowerVR SGX530 3D GPU
eMMC Onboard Storage 2GB (MMC1)
SD Card Storage (MMC0)
512 MB DDR3L RAM
Video Outputs
- HDMI Video Output (with audio)
SMSC LAN8710A Ethernet

Setting up the Haiku SD card

The BeagleBone Black supports booting from an microSD card while the boot switch is pressed at power on. A MBR file system layout is normally used as seen below. Partition 1 is all that is required to boot an OS.

partition 1 -- FAT32, bootable flag, type 'c'
partition 2 -- BeFS, Haiku filesystem, type 'eb'

Boot Partition

Required files

MLO
u-boot.img: u-Boot image
uEnv.txt: u-Boot Environment settings

Optional files

ID.txt: Unknown

Compiling

Create your work directory mkdir generated.beagle; cd generated.beagle
Build an ARM toolchain using ../configure --build-cross-tools arm ../../buildtools --target-board beagle
TODO

Booting

If the boot switch is not depressed: MMC1, MMC0, UART0, USB0
If the boot switch is depressed: SPI0, MMC0, USB0, UART0

Emulation

The Linaro Fork of QEmu has beagle board (and other OMAP3) support. https://launchpad.net/qemu-linaro

It seems you get this as the default QEmu install on some, but not all, Ubuntu versions. For other distros (or Haiku), you'll have to compile it yourself.
