Is MTL a Meteor Lake and ADL Alder Point?

Is it possible to test the chipsets that used to be after Meteor in the enum, and now they are before?

File ichspi.c:

PS10, Line 1853: mmio_readw
Why it is `readw` (reads into uint16_t) here, but `readl` below (reads into uint32_t)?
You declare `region_read_access` and `region_write_access` as uint32_t actually

PS10, Line 1854: 		*region_write_access = mmio_readw(ich_spibar + ICH_REG_BIOS_BM_WAP);
Maybe you can also add some debugging prints in this branch too

I don't think this needs to be inline?

               : 		return 16;
               : 	return 8;
maybe make it one line
`return (ich_generation >= CHIPSET_METEOR_LAKE) ? 16 : 8;`

Let's re-order Meteor Lake here too

you can leave the word "registers", so that it is "... and region access registers"
