[PATCH for-9.0 v11 00/18] rv64i and rva22u64 CPUs, RVA22U64 profile support

[Daniel Henrique Barboza]

Hi,

In this new version we added a new function, riscv_cpu_enable_named_feat(),
to allow profiles to enable named features.

This doesn't have much of an impact for this current work - the only
named feature we're using here is zic64b and the default block size
values already satisfies it.

The reason we're doing this change now is due to the incoming RVA22S64
support. A new named featured called 'svade' will be added for it, and
'svade' is NOT enabled by default in QEMU. Profiles will need to enable
named features to support RVA22S64, so might as well implement this
capability right from the start.

Series based on master.
