FreeBSD on Raspberry Pi 512MB (with U-Boot + ubldr)

[Daisuke Aoyama]

Hello,

The recent change about "fdt addr" is very interesting.

So, I'm building with FreeBSD 10-current(svn 243675 + fdt-memreserve.diff).
It needs some little modification to U-Boot.

My first impression is "The time is not stable".
However, it works on Raspberry Pi w/512MB! Thank you for porting.

You can download my test binary from:

http://www.peach.ne.jp/archives/rpi/freebsd-pi-20121130.img.gz

Download and decompress it, then write it to SD.
This image requires SD 4GB or more.
I'm using as headless. So, you need a serial console for seeing the boot 
log.
If you need to change the value on it, please mount the second partition 
(e.g. /dev/da0s2a).

Note: first time, it takes about 2 minutes due to generate the SSH keys.

BTW, SDHCI is not yet stable?
