Please print this memory range the same way we print resources, e.g.,
"%#010llx-%#010llx", with "addr" and "addr + new_size - 1".

I think that width includes the "0x" prefix, so it's really eight digits.

I know you think it's prettier to have zeroes and extra spaces like this:

[0xe7000000 - 0xe8000000, 0x1000000 bytes]

rather than a bunch of 'F's:

[0xe7000000-0xe7ffffff]

But for the record, I still think you're wrong and that it's better
to be consistent even if it's slightly uglier. The inconsistencies
lead to confusion and off-by-one errors.

We can make them to be consistent later.

current for early mem stage, it is consistent to without -1.

later I like to see all pci resource could be consistent to without -1 too.

Thanks
