A patch for NAND uclass support was proposed about half a year ago:

It was not merged and I do not see on-going work for this.
Without DM-based probing, we need to set up pinctrl etc. in an ad-hoc
way and give lots of crappy CONFIG options for base addresses and
properties, which are supposed to be specified by DT. This is painful.
This commit just provides a probe hook to retrieve "reg" from DT and
allocate private data in a DM manner. This DT driver is not essentially
a NAND driver, in fact it is (ab)using UCLASS_MISC. Once UCLASS_NAND is
supported, it would be possible to migrate to it.

At present the ICH SPI controller driver reads the controller lock
status from its register in the probe routine and saves the lock
status to a member of priv. Later the driver uses the cached status
from priv to judge whether the controller setting is locked and do
different setup.
But such logic is only valid when there is only the SPI controller
driver that touches the SPI hardware. In fact the lock status change
can be trigged outside the driver, eg: during the fsp_notify() call
when Intel FSP is used.
This changes the driver to read the lock status every time when an
SPI transfer is initiated instead of reading the cached one.
