Replied here earlier, but pressed the wrong key & it only went to the
list.
I think this patch probably also needs to grow a Fixes tag, for
commit f2863f30d1b0 ("riscv: errata: Add Andes alternative ports").

The 4 Kconfig patches ideally would've been in a series, since 3 of the
4 seem to be fixes & the 4th depends on one of the fixes being applied.

Thaks,
Conor.
