Hi Saul,
I am working on Bug 6487 - Add Aarch64 qemu target. I take tune and config
files from linaro then succeeds to build core-image-minimal and
core-image-sato.
And I have 2 question about it now:
1 What should the new qemu aarch64 bsp looks like at the end? Do the files
in the patch attached are enough? And what more test should we do except to
build images such as core-image-sato, core-image-sato even build world?
may be eventually support linux-yocto, and linux-linaro both, it should
be tested at same level as other QEMU BSPs
2 There 2 aarch64 configure files from linaro. First one is little endian
and it is as default, and the other one is big endian. I take the little
endian one as qemuarm64.conf as linaro does. Do we need add the other one as
qemuarm64_be.conf or something like that?
Name them same as meta-linaro please, so eventually linaro layer can
drop it and take up the maintenance of them in OE-Core
Keep same name with linaro is convenient for merge work. But the name
'genericarmv8' is not coordinated with existing qemu bsps. I prefer to
use qemuarmv8 for coordination.

Kai
