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: Max resolution of 7680 is conditional on
|
|
being Pi4
|
|
|
|
The max resolution had been increased from 2048 to 7680 for all
|
|
platforms. This code is common with Pi0-3 which have a max render
|
|
target for GL of 2048, therefore the increased resolution has to
|
|
be conditional on the platform.
|
|
Switch based on whether the bcm2835-v3d node is found, as that is
|
|
not present on Pi4. (There is a potential configuration on Pi0-3
|
|
with no v3d, but this is very unlikely).
