> There are numerous drivers disabled...

The 64-bit Allwinner SoCs share a lot of devices with their 32-bit predecessors (or siblings), so we also share some config symbols, most prominently ARCH_SUNXI. However some of those supported devices are only in older SoCs (Sun4i generation, for instance), and will never be needed for an *arm64* kernel (take Sun4i sound drivers, for example). In the wake of avoiding to bloat the kernel (or the number of modules) needlessly, we can safely disable drivers for which there is no AArch64 capable SoC using those devices. I marked those as "not in 64-bit Allwinner SoCs" in the list above.

I understand that, and can see the reasons why. It's just for my work (hacking and testing kernels, and not being on Ubuntu) it's very inconvenient to always build a matching initrd, and it's just those two symbols needed to boot into an SD card based rootfs without one.
If this is of no concern for you, then it's fine to leave them as =m.

Thanks!
