[PATCH v2 0/2] hw/pflash: implement update buffer for block writes

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

Respin of Gerd's series [*] using the LD/ST API.

v1 [*] cover:

  When running qemu with edk2 efi firmware on aarch64 the efi
  variable store in pflash can get corrupted.  qemu not doing
  proper block writes -- flush all or nothing to storage -- is
  a hot candidate for being the root cause.

  This little series tries to fix that with an update buffer
  where block writes are staged, so we can commit or discard
  the changes when the block write is completed or canceled.
