[U-Boot] [PATCH 0/2] Standardize on run-time board ID variables

[Tom Rini]

Hey all,

I've been thinking about one of the problems we need to solve over in TI
AM335x land and that is given that we support a number of different
boards with a single binary (and we have an i2c eeprom that tells us
what board and revision we are on), the user needs to be able to easily
determine what board we are on so they know what dtb file to load so
they can boot.  To this end I've added
CONFIG_ENV_VARS_UBOOT_RUNTIME_CONFIG to the README which says when set
we have board_name and board_rev set at run-time.  Then for am335x[1]
set that and CONFIG_BOARD_LATE_INIT which will set the variables and add a
command, findfdt to compare and set fdtfile correctly.  Further
distro-specific logic can then augment this to figure out what
filesystem / partition to read from.

[1]: Yes, this will need re-working after merging Peter K's patches to
allow for non-TI boards.
