The kernel submodule we use is at v6.6.3, but the kernel configuration
is for v6.7.0-rc4. Run `make ARCH=arm64 olddefconfig` to roll it back.

The kernel config for MT8183 can already boot on Hana boards. The lowest
of depthcharge size limits on ARM64 is a comfortable 32MiB, so we can
try to create a arch-generic kernel, and probably even an arch-generic
image. Rename the config and its references to "a64" as in the Makefile.

Enable USB-attached SCSI in the ARM64 kernel, useful for some external
USB-to-SATA disks and the like.

Add configs for RK3399 Chromebooks based on device-tree analysis. It
boots on Kevin with everything looking like it works, and even tries to
boot into Debian, but can't. It can't even kexec itself, so I expect
something is breaking down when it's trying to shutdown before launching
the next kernel. I occasionally had display problems around suspend, so
maybe rockchip-drm doesn't handle being deinitialized well.

Based on the device-trees, following are still missing:

     INPUT_MOUSE n -> y
     INPUT_TOUCHSCREEN n -> y
     ROCKCHIP_CDN_DP n -> y

ROCKCHIP_CDN_DP is about display over USB-C, needs firmware so disabled.
USB_PHY and ARM_GIC_V3_ITS_FSL_MC cannot be selected, have no prompt.

Enable the pin controller for MT8186. Looks like most other necessary
configs for MT8186 are enabled, as far as I can tell from device tree
compatibles. The following are still missing but none of which look
essential for booting:

     REMOTEPROC n -> y

CROS_EC_RPMSG and REMOTEPROC are about MTK_SCP, which needs firmware.

Enable the MT1892 pin controller and clocks. The clocks might or might
not be optional, but better not risk it being broken, we are not limited

ARM_DSU_PMU is about performance monitoring. PHY_MTK_UFS and
SPI_SLAVE_MT27XX actually look unused, have status = "disabled".

This tries to enable configs for SC7180 Chromebooks based on device-tree
files, but I have no idea how much of it is useful, or if the end result
works at all. There are more things from device-trees, but none I could
