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] overlays: Rename pi3- overlays to be less
|
|
model-specific (#3052)
|
|
|
|
Rename the various pi3- overlays to be more generic, listing
|
|
the devices they apply to in the README. The original names are
|
|
retained for backwards compatibility as files that just include
|
|
the new versions - the README marks them as being deprecated.
|
|
|
|
See: https://github.com/raspberrypi/firmware/issues/1174

|
- UART0/ttyAMA0 over GPIOs 14 & 15. Note that this may reduce the maximum

- usable baudrate.
|
|
-
|
|
- It is also necessary to edit /lib/systemd/system/hciuart.service and
|
|
- replace ttyAMA0 with ttyS0, unless you have a system with udev rules
|
|
- that create /dev/serial0 and /dev/serial1, in which case use /dev/serial1
|
|
- instead because it will always be correct.
|
|
-
|
|
- If cmdline.txt uses the alias serial0 to refer to the user-accessable port
|
|
- then the firmware will replace with the appropriate port whether or not
|
|
- this overlay is used.
