CONFIG_SYS_BOARD is the board config name, which may differ from the
board name given to make.

CONFIG_SYS_BOARD_NAME is set to the name in boards.cfg.

To illustrate using existing boards in boards.cfg look at for example
the spear boards.

spear300                     arm         arm926ejs   spear300            spear          spear       spear3xx_evb:spear300
spear300_nand                arm         arm926ejs   spear300            spear          spear       spear3xx_evb:spear300,nand
[...]
spear320_usbtty_nand         arm         arm926ejs   spear320            spear          spear       spear3xx_evb:spear320,usbtty,nand


CONFIG_SYS_BOARD is spear3xx_evb on all 16 of these as they are the same "board" with only different CONFIG_.. parameters set via boards.cfg.

CONFIG_SYS_BOARD_NAME is the first column, unique on each.

> In any case, documentation for CONFIG_SYS_BOARD_NAME is missing.

This should go in README?
