Re: [PATCH v2 2/2] mtd: spi-nor: macronix: Restore fallback parameters for MX25L12805D

Hello,

> In a previous effort to drop flash_info fields and rely on SFDP, the
> static size and no_sfdp_flags were removed from the MX25L12805D entry
> (JEDEC ID 0xc22018).
>
> At that time, the legacy MX25L12805D was already EOL and unavailable
> for physical testing. Verification was inadvertently performed using
> the newer MX25L12833F, which shares the same JEDEC ID but supports
> SFDP. As a result, the probe succeeded during testing, leading to
> the mistaken removal of the fallback parameters.
>
> Since the actual MX25L12805D lacks SFDP support entirely, it strictly
> requires these static parameters.
>
> Restore .size = SZ_16M and .no_sfdp_flags = SECT_4K to this entry
> to fix the probe failure for the legacy part.
