Mostly looks OK, I think.
One major point:
* I think we should make sure we include a list of the caveats about
the vexpress-a15 model. To steal some text from a mail I sent linaro-dev
a little while back:
* the A15 CPU emulated will *not* include emulation of LPAE,
Virtualization extensions or TrustZone; you can boot a Linux
kernel compiled for A15-without-LPAE, but this is definitely
not going to be of any use to you if you wanted to test
Xen/KVM/hypervisor type code on a model.
* this is not (at least initially) going to be a "supported"
platform model for Linaro, as it is primarily intended to
help us as we work on KVM for the Cortex-A15. So you can try
it but we don't promise to do anything if it doesn't work :-)
* there is not as yet any Linaro "hardware pack" for the A15,
so you will be on your own for putting together a kernel,
user space, etc.
You might want to rephrase some of that for this audience, but
I think we should be clear that when we say we've done a
"vexpress-a15" model we don't mean that it is a complete
model or that we intend to support it as a Linaro platform yet.
And some nits:
* You say
git://git.qemu.org/qemu.git rev 77b63650b4986914c5591bbb45855b02d7102db5
but that git commit isn't in upstream qemu.git, it's a qemu-linaro commit.
* the "and" is misplaced in the credits list at the bottom
