[RFC PATCH 0/2] exec: Fix (too) short device accesses

[Philippe Mathieu-Daudé]

Something noticed while debugging Alexander's bug report
"Hang with high CPU usage in sdhci_data_transfer":
https://bugs.launchpad.net/qemu/+bug/1878054

The flatview ignores the MemoryRegion minimum access size.

It seems related to a similar issue Julia had with PCI
devices.

Not sure it is safe enough, have performance penalties
and so on, so RFC.

Philippe Mathieu-Daudé (2):
  exec: Let memory_access_size() consider minimum valid access size
  exec: Do not let flatview_read/write_continue do (too) short accesses
