From: Fabio Estevam fabio.estevam@freescale.com
FSL 2.6.35 kernel assumes that the bootloader passes the CONFIG_REVISION_TAG information.
The kernel uses this data to distinguish between Dialog versus mc34708 based boards, and also to distinguish between revA and revB of the mc34708 based boards.

As you said, could you please use accessor for it?
