Most do though. Since you're on ARM, choosing another ARM target is good.
How about the ebsa285 since it's well established. Look at hal_diag.c but
ignore the "compatibility with older stubs" bits. And then hal_diag.h and
plf_stub.h. edb7xxx is another option.
When you have it going, if you have any (preferably specific :-)) changes
to the document we'd be happy to take them. That goes for anyone! We know
it's still incomplete.
