The following depends on v2 of the "Improve falcon mode and am335x_evm
docs" series, as that adds the README to start with.

The AM335x GP EVM ships with NAND. Document programming of the chip
including the redundant locations that the ROM will check.

You've already done a "nand erase.chip"... Why do you need to erase
"kernel" again?

No, that's just what I get for concatening my instructions too
quickly, thanks!
