that imx-i2c driver keeps deferring the probe because of the DMA is not

available if the DMA driver is not enabled).

Commit 7ee7ef24 ("scsi: arm64: defconfig: enable configs for Hisilicon ufs")
set 'CONFIG_SCSI_UFS_HISI=y', but the configs it depends
on

  (CONFIG_SCSI_HFSHCD_PLATFORM && CONFIG_SCSI_UFSHCD)

were left to being built as modules.

Commit 1f4fa50d ("arm64: defconfig: Regenerate for v4.20") "fixed"
that by reverting to 'CONFIG_SCSI_UFS_HISI=m'.

Thing is, if the rootfs is stored in the on-board flash (which
is the "canonical" way of doing things), we either need these drivers
to be built-in, or we need to fiddle with an initramfs to access that
flash and eventually load the modules installed over there.

The former is the easiest, do that.

Intel Stratix10 service layer driver was added with commit 7ca5ce89
("firmware: add Intel Stratix10 service layer driver").

Intel Stratix10 service layer provides kernel APIs for drivers to request
access to the secure features. Such features include FPGA programming,
remote status update, and read and write secure registers.

While clients of the service layer can be built as modules, the service
layer itself has to be configured as built-in.  The service layer is
dependent on ARCH_STRATIX10.
