[PATCH RFT] ArmVirtPkg/ArmVirtXen: move from Intel to generic BDS

[Ard Biesheuvel]

ArmVirtXen is the only remaining consumer of ArmPlatformPkg's
PlatformIntelBdsLib implementation, which is tightly coupled to the
deprecated Intel BDS. So move ArmVirtXen to the generic BDS as well,
allowing us to get rid of PlatformIntelBdsLib entirely.

The patch looks fine, and I agree that the main thing that should decide
about it is testing by Julien.

It was in my list of UEFI part I wanted to look next :).
I tested it and hit the following assert:

ASSERT [BdsDxe] /home/julieng/works/edk2/ArmPkg/Library/PlatformBootManagerLib/PlatformBm.c(502): 0 == 4

Looking at the ArmVirtQemu.dsc, I made the below modification.
When I tried the version protected by TTY_ENABLE, the ASSERT was
still present.

Hmm, looking again, what you tried should actually be equivalent.
Could you try a clean rebuild please? Thanks.

I have applied your 2 patches and test a clean rebuild. I have seen no 
issue.

Feel free to add my tested-by.

Thanks all.
