Hi Krzysztof,

Thank you for your fast review and apologies for the typo. I forgot to
mention on the commit message but I have mentioned in the cover letter
that the driver is needed for the Blaize BLZP1600 CB2 board which is
already supported on v6.14. I will fix the commit message on V2.

This driver enables support (controls) for multiple peripherals on
the board, like Ethernet for NFS boot, SD and eMMC to load modules from
these media. Without this driver build in the kernel, it will be hard to
mount a filesystem and load modules.

Kind regards,
Nikolaos
