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?

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?

We need the kernel support to match the linux-yocto* home for the other core/emulated BSPs .. that way I can help support, test and bring everything forward. We have a 3.14 and 3.16+ version of the recipe available, and I've looked into this in the past ... the delta needed in those kernel versions is not significant.
