In order to write an event log, the ROM load notification handler needs
two more fields.

IMHO it makes more sense to squash that in the "hw/core/loader:
Add ROM loader notifier" patch introducing that API.

Description of the loaded ROM.

Or 'blob', blob_ptr. Maybe declare as 'const void *'?

Now easier to document, where 'data' is addressed in guest memory.

Size of 'data'.

Still unused. Drop?

Yes I'd squash it if we decide that the patch 25, which needs this, is
useful. But it's possible that no one actually needs it so I left this
separate for the moment.

Thanks, I'll fix those
