Allow appending a dtb blob to the binary and use it for identifying the board. Fall back to nvram based identification in case of no dtb passed. Signed-off-by: Jonas Gorski <jogo@openwrt.org> SVN-Revision: 42119

Subject: [PATCH 47/48] MIPS: BCM63XX: add support for matching the board_info
|
|
by dtb
|
|
|
|
Allow using the passed dtb's compatible property to match board_info
|
|
structs instead of nvram's boardname field, which is not unique anyway.
