Changes in v4: - merge patch 2(support octaflash Id) to patch 1(support octal dtr) - add switching back to default mode(1-1-1) support if octal dtr is disabled - delete the duplicate code settings initialized by the Profile 1.0 table. (such as cmd_ext_type, rdsr_dummy, rdsr_addr_nbytes, etc.) - add a description about stacked die Changes in v3: - Add support for Macronix octaflash series. Changes in v2: - Define with a generic name to describe the maximum dummy cycles. - Compare the ID directly in the loop, no longer copy and execute memcmp(). - Add spi_mem_dtr_supports_op() to support dtr operation.
