Kevin,
You will need the 2.6.27 kernel. I got a g20 on Friday and successfully
booted it. I used an oct 22 buildroot snapshot, and selected the 2.6.27
kernel. I initially did the buildroot configuration for the 9260.
After everything was completed I went back and did a kernel "make
at91sam9g20ek_defconfig, and redid the top level "make". From what I
can see, there is no g20 support outside of the kernel (as of a few
weeks ago).
For my initial testing I grabbed pre build bootstrap & u-boot for the
9g20 from linux4sam
(ftp://www.linux4sam.org/pub/uboot/u-boot-1.1.5_atmel_1.7/u-boot-1.1.5_atmel_1.7-at91sam9g20ek-dataflash.bin).
(ftp://www.linux4sam.org/pub/at91bootstrap/AT91Bootstrap_9g20/dataflash_at91sam9g20ek.bin)
I suspect the buildroot bootstrap & u-boot will work fine, but I have
not tested them.
