-Subject: [PATCH] mtd: m25p80: allow fallback from spi_flash_read to regular
- SPI transfer
-
-Some flash controllers, e.g. on the ath79 platform can support a fast
-flash read via memory mapping, but only if the flash chip is in
-3-byte address mode.
-
-Since spi_flash_read_supported does not have access to the same data as
-spi_flash_read, the driver can't detect an unsupported call until m25p80
-has decided to use spi_flash_read.
-
-Allow the driver to indicate a fallback to a regular SPI transfer by
-returning -EOPNOTSUPP
