Raspbian and Fedora have decided to support the Pi3 in 32-bit mode for
|
|
|
|
|
now, so it's useful to be able to test that mode on an upstream
|
|
|
|
|
kernel. It's also been useful for me to use the same board for 32-bit
|
|
|
|
|
and 64-bit development.

v1: Gerd's patch that put the ../../../arm64/... link in the Makefile
|
|
|
|
|
v2: Michael's patch that #included from ../../../arm64/... in a new
|
|
|
|
|
bcm2837-rpi-3-b.dts.
|
|
|
|
|
v3: Mine, using symlinks to make sure that we don't break the split DT
|
|
|
|
|
tree.
