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 09/10] MIPS: BCM63XX: allow board files to provide sprom
|
|
fixups
|
|
|
|
Allow board_info files to supply fixups for the base sproms to adapt
|
|
them to the actual used sprom contents in case they do not use the
|
|
default ones.
