Can you please stop spreading this FUD?
As I said before, Arm64 kernels have supported more than one specific
hardware platform at runtime from the beginning of the arm64 port
(assumed the needed platform support has been enabled in the kernel
config, of course).
Even most arm32 kernels support this, since the introduction of the
CONFIG_ARCH_MULTIPLATFORM option. In fact every recently
introduced arm32 platform is usually v7, and must conform to this.
The sole exceptions are very old platforms, and the v4/v5/v6/v7 split
due to architectural issues (the latter still support clusters of
platforms in a single kernel).
Thank you, and have a nice weekend!
Gr{oetje,eeting}s,
Geert
