NAK, not only is selecting user-visible symbols generally frowned upon, and ignoring their dependencies even worse, but for a multiplatform kernel the user may well want this to be a module.
If having the SMMU driver built-in is somehow fundamentally required for this platform to boot, that would represent much bigger problems.
The SoC can boot without SMMU and PDMA, but not GIC, pinctrl or the arch timer. I see that most other SoCs still select drivers and frameworks they presumably need for booting, with the exceptions of ARCH_BITMAIN, ARCH_LG1K and a couple others. Which of these two options should I go for?
