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. Despite, since subtargets range from bcm2708 to bcm2711, it seems appropriate to use bcm27xx instead of bcm2708 (again, as already done for BOARDNAME). This also renames the packages brcm2708-userland and brcm2708-gpu-fw. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de> Acked-by: Álvaro Fernández Rojas <noltari@gmail.com>

Subject: [PATCH] Fix for Pisound kernel module in Real Time kernel
|
|
configuration.
|
|
|
|
When handler of data_available interrupt is fired, queue_work ends up
|
|
getting called and it can block on a spin lock which is not allowed in
|
|
interrupt context. The fix was to run the handler from a thread context
|
|
instead.
