In the downstream driver, branch lf-6.12.3_1.0.0, t his seems to be
MrvlIEtypes_fw_cap_info_t for things like:

FW_CAPINFO_EXT_802_11AX, FW_CAPINFO_EXT_6G ....

This looks like MrvlIEtypes_Secure_Boot_Uuid_t. Doesn't seems too
important.

Yep, it is working. Thank you! I am testing this on FRDM-iMX93, which has
IW612 revision 1.0.

I have to use nxp/sd_w61x_v1.bin.se on this board and NULL firmware_sdiouart
because it seems that firmware return 1 as "strap" value, even if WiFi
is definitely connected over SDIO.
