This adds support for the AT91SAM9G20 boards by taskit GmbH. Both boards, Stamp9G20 and PortuxG20, are integrated in one file. PortuxG20 is basically a SBC built around Stamp9G20.

Are more taskit based boards expected? If not taskit/stamp9G20 could be reduced to just taskit
Yes, there are more taskit boards expected.

Change immediates to logical #defines
Sorry, I don't get that clearly. In the moment I would take that to mean that I should do something like #define CONFIG_BOOT_PARAMS CONFIG_SYS_SDRAM_BASE + 0x100 in the appropriate place and use here: gd->bd->bi_boot_params = CONFIG_BOOT_PARAMS or am I wrong?
