Adrian Schmutzler 7d7aa2fd92 brcm2708: rename target to bcm27xx
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.

Subject: [PATCH] BCM270X_DT: Add new Ethernet DT parameters
Add "eth_downshift_after" DT parameter to allow the delay before the
downshift to be specified. The default is 2 auto-negotiation cycles,
and legal values are 2, 3, 4, 5 and 0 (disabled).
Add "eth_max_speed" DT parameter as a way of prohibiting 1000Mbps
links. This can be used to avoid the delay until the downshift mechanism
activates. Legal values are 10, 100 and 1000, where the default is
unlimited (effectively 1000Mbps).
