Subject: [RFC PATCH 0/3] mtd: spi-nor: Tackle stateful modes

My biggest concern with Pratyush's patches is that the stateful modes case
(X-X-X modes that are entered via a non-volatile bit) is not handled.
This is an attempt to tackle this problem. Reasons and explanations in
the commit messages.

Tudor Ambarus (3):
  mtd: spi-nor: Introduce SNOR_F_IO_MODE_EN_VOLATILE
  mtd: spi-nor: Introduce MTD_SPI_NOR_ALLOW_STATEFUL_MODES
  mtd: spi-nor: Parse SFDP SCCR Map
