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] fork_cacheflush
|
|
|
|
On ASUS WL-500gP there are many unexpected "Segmentation fault"s that
|
|
seem to be caused by a kernel. They can be avoided by:
|
|
1) Disabling highpage
|
|
2) Using flush_cache_mm in flush_cache_dup_mm
|
|
|
|
For details see OpenWrt ticket #2035 https://dev.openwrt.org/ticket/2035
