Hello.
I=E2=80=99ve been taking a stab at getting an arm64 kernel running on =
qemu acting as a Zynq Ultrascale evaluation board. The first hurdle was =
getting the u-boot API and ubldr to compile and run in 64-bit mode. =
I=E2=80=99ve managed to get that much to work and wanted to let you know =
in case this is interesting and I can share the code. Or, so you can =
tell me that u-boot/ubldr is the wrong approach.
In any case, here=E2=80=99s how far it boots. The next step is to whip =
my kernel configuration into shape but I may have to put this aside =
until after the holidays.
Cheers,
=E2=80=94Thomas
