I thought we agreed to something like:
SIAA0000
Where 'S' is the designator for the special items like PCI-E and
internal-regs. 0 = normal target ids, 0xF = special ids.
The target is only 4 bits, the attr is 8, so a little doc update to
clarify this should be enough, no need to change the DTs.
+1 for SIAA0000, as it allows to use MBUS_ID also for those fake
windows. It makes it more readable IMHO.
Also allows you to have up to 40b offset, which _might_ be important
with LPAE enabled.
