This change makes the names of Broadcom targets consistent by using the common notation based on SoC/CPU ID (which is used internally anyway), bcmXXXX instead of brcmXXXX. This is even used for target TITLE in make menuconfig already, only the short target name used brcm so far. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>

Subject: [PATCH 46/48] 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.
