[Qemu-devel] [PATCH 02/17] hw/pflash_cfi01: Make read after byte-write or erase return status

[Peter Maydell]

The Intel flash command set requires that a read operation after
doing a 'single byte write' command returns the status register;
add this case to pflash_read() so we return the correct information.
Similarly, the case for the 0x28 flavour of block erase was missing.
