[PATCH v13 00/26] riscv: RVA22 profiles support

[Daniel Henrique Barboza]

Hi,

This is a merge of the two profile series:

"[PATCH for-9.0 v12 00/18] riscv: rv64i/rva22u64 CPUs, RVA22U64 profile support"
"[PATCH for-9.0 v2 0/8] target/riscv: implement RVA22S64 profile"

I'm sending them together since the second series is dependent on the first.

Quick summary of the major features added:

- A new rv64i CPU type. This is a CPU that has only RVI enabled;

- 'rva22u64' and 'rva22s64' profile flags. They were designed to be used
  with the 'rv64i' CPU but can be used with other generic CPUs like
  rv64;

- Two new profile CPUs: 'rva22u64' and 'rva22s64'. A profile CPU is an
  alias of '-cpu rv64,profile=on' and it's the most convenient way of
  using profiles. E.g to launch an rva22s64 'virt' machine:

  ./qemu-system-riscv64 -M virt -cpu rva22s64  (...)

  To test an application with an rva22u64 profile with linux-user mode:

  ./qemu-riscv64 -cpu rva22u64  (...)
