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 03/11] MIPS: BCM63XX: move code touching the USB private
|
|
register
|
|
|
|
This patch moves the code touching the USB private register in the
|
|
bcm63xx USB gadget driver to arch/mips/bcm63xx/usb-common.c in
|
|
preparation for adding support for OHCI and EHCI host controllers which
|
|
will also touch the USB private register.
