+Subject: [PATCH 1/2] hw/pflash_cfi01: Make read after byte-write or erase
+ return status
+
+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.
