Null Data Phases

[Bert Marston <bert@quadic.com>]

Does anyone know if it is legal for a PCI-PCI bridge to convert a 64-bit
null data memory write transaction on the source side to a 32-bit null
data memory write transaction on the destination side?  If it is legal,
can any burst memory write with all the byte enables de-asserted be
converted to a single null data phase transaction?

Thanks,
Bert Marston
