 Not expecting this to be looked at the moment, just storing for future
 reference:

 With #12249 accounted for, arm-3.5  boots on XO-1.75 with kernel
 b152b4013c271edfe614e25c79647b2e3e2ae5aa with OFW head from today.

 The next few commits do not compile, until we get to
 101e1e7e21d1f2924b2fb27e9c582289b5fb0974 - the next compilable tree, it
 does not boot on XO-1.75. No messages over serial, it just hangs really
 early. Even when all sound support is disabled.

 Workaround:
 {{{
 git checkout b152b4013c271edfe614e25c79647b2e3e2ae5aa arch/arm/mach-
 mmp/mmp2.c
 git checkout b152b4013c271edfe614e25c79647b2e3e2ae5aa arch/arm/mach-
 mmp/mmp2-dt.c
 }}}

 Then arm-3.5 is usable all the way up til e5abc51b, where XO-4 S/R work
 walks all over MMP2 support for the time being.
