[PATCH] riscv: Kconfig.errata: Add dependency for RISCV_SBI in ERRATA_ANDES config

[PATCH] riscv: Kconfig.errata: Add dependency for RISCV_SBI in ERRATA_ANDES config

[Prabhakar]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

Andes errata uses sbi_ecalll() which is only available if RISCV_SBI is
enabled. So add an dependency for RISCV_SBI in ERRATA_ANDES config to
avoid any build failures.

I'm still seeing build warnings/errors after applying all 3 RISC-V
Kconfig patches from today (2023 SEP 01).

You need to apply patch [1] aswell.

I tested the failing builds that I had - after applying all 4 patches only,
not each patch separately.

If that is satisfactory, you can add

This one needs to grow the same fixes tag.
Ideally the whole lot of kconfig bits would be in a series IMO.

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.
