Right. In that case, we can just skip the min(..) as well.

File src/soc/intel/common/block/fast_spi/fast_spi_flash.c:

PS30, Line 51: _get_fast_spi_flash_ctx
It would be better to use consistent naming conventions: _fast_spi_flash_get_ctx


PS30, Line 58: bar
assert if bar is 0.


PS30, Line 91: read_fast_spi_flash_sfdp_param
fast_spi_flash_read_sfdp_param


PS30, Line 325: 0x04
Should this be fixed? :)
