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] drm/vc4: Correct handling of rotation parameter in
|
|
fkms
|
|
|
|
One bit within DRM_MODE_ROTATE_MASK will always be set to
|
|
determine the base rotation 0/90/180/270, and then REFLECT_X
|
|
and REFLECT_Y are on top.
|
|
|
|
Correct the handling which was assuming that REFLECT_[X|Y]
|
|
was instead of ROTATE_x.
