Hmm, when building this with the BUILDBOT config (CONFIG_BUILDBOT)
and throw in the CONFIG_ALL_* for userspace + kernel modules for
good measure. It fails with the default world build (without the
V=s option) because the following symbols are not yet defined in
either the generic or gemini-specific kernel config.

CONFIG_COMPAT_32BIT_TIME
CONFIG_PCIEASPM
CONFIG_MTD_PHYSMAP_IXP4XX
CONFIG_GPIO_CDEV_V1
CONFIG_CPU_THERMAL
CONFIG_DMA_PERNUMA_CMA

At least CPU_THERMAL is also a show-stopper for apm82181 5.10,
so should these just be added added as either disabled
(# CONFIG_ ... is not set) or in case of CONFIG_PCIEASPM=X
(whatever the default is there) in target/linux/generic/config-5.10?

Or CPU_THERMAL could be an issue for some high-powered x86 or ARM?
