However, RES only returns one byte and there are multiple flash chips with different sizes on the market and all of them have the same RES ID. REMS is from the same age as RES, but it provides a manufacturer and a device ID. It is therefore on par with the probing for parallel flash chips and specific enough.

* Try RES even if RDID failsCarl-Daniel Hailfinger2008-11-271-7/+5
| | | | | | | | | | | | | | | | | | | The existing check in probe_spi_res() was right for SPI controllers which support all commands, but may not exist. For controllers which support only a subset of commands, it will fail in unexpected ways. Even if a command is supported by the controller, it may be unavailable if the controller is locked down. The new logic checks if RDID could be issued and its return values made sense (not 0xff 0xff 0xff). In that case, RES probing is not performed. Otherwise, we try RES. There is one drawback: If RDID returned unexpected values, we don't issue a RES probe. However, in that case we should try to match RDID anyway.
