Subject[RFC PATCH V2 32/38] riscv: s64ilp32: Validate harts by architecture name
Date
From: Guo Ren <guoren@linux.alibaba.com>

When rv64ilp32 was introduced, the 32BIT would work with rv64,isa. So
use the architecture name instead of the ABI width name. This is an
addition to the commit: 069b0d517077 ("RISC-V: validate riscv,isa at
boot, not during ISA string parsing").
