[PATCH 0/2] handle RDCR opcode for Macronix

Posted by Maarten Zanders 1 week, 2 days ago

This series introduces a configurable RDCR (Read Configuration Register)
opcode for spi-nor flashes and applies a fix for Macronix devices.

Patch 1 adds a new flash parameter to hold the RDCR opcode, defaulting
to 0x35 (JEDEC standard).

Patch 2 applies a Macronix-specific fixup, setting the RDCR opcode to
0x15.
