This isn't specific to the SK, more the AM62x in general, suggest name
am62x.rst.

These compiler names might not be the same as installed by some current package managers (-none),
maybe we start by setting up two env vars to point to the two compilers we use:

export CROSS_COMPILE32=arm-none-linux-gnueabihf-
export CROSS_COMPILE64=aarch64-none-linux-gnu-

Then just use those below, that way we only have to switch these first two commands if we
have a different compiler.

CROSS_COMPILE=$CROSS_COMPILE32

etc..

Lets not pollute directories outside of the current one, suggest `O=build/r5`
and the same below.
