Couldn't you just latch the value when one half is accessed?
In this one specific case you could do that but this is not the only
case in sparc32 (TOD, MXCC, ...) and other architectures with 64 bit
hardware have similar requirements.
This is a generic solution that fills a hole in the qemu
implementation.
Agreed. Some non-PC hardware has 64-bit registers which need to be
accessed as 64-bit quantities, in order to read or write all fields at
once. Qemu should support 64-bit I/O.
