Thanks Kevin, for the review.

We can detect the board using on-board EEPROM, so same mach-id
should work for both EVM and Beagle. 
And also going forward with device tree approach we may
not need different id's, right?

But I am surprised to see that beaglebone is booting fine for you,
did you get Linux console?
Actually the board won't boot without some patches,
(I have published on arago), especially inside, gpmc_init,
omap_sram_init, omap3_pm_init and omap3_twl_init.
