[PATCH 0/1] README.hardware: update installation instructions for beagleboard

[Darren Hart]

Without having the hardware to test, these instructions should resolve the boot
issues Yi experienced on the Beagleboard C4. These were arrived at through
discussions on the freenode #beagle channel. Thanks to Ceriand and woglinde.

A physical test by any one of those Cc'd following the updated instructions
would be appreciated.

The following changes since commit 72f06800bcf6f3d188b99bd0c359f5ef74879621:

  u-boot: remove old SRCREV from poky-default-revisions.inc (2011-05-20 09:22:18 -0700)

That shouldn't be needed

And that's 'nand erase.chip' nowadays
