[PULL 03/44] hw/mips/loongson3_virt: Relax CPU restrictions for TCG


From: Philippe Mathieu-Daudé
Subject: [PULL 03/44] hw/mips/loongson3_virt: Relax CPU restrictions for TCG
Date: Tue, 11 Jul 2023 00:25:30 +0200

From: Jiaxun Yang <jiaxun.yang@flygoat.com>

After implemented CPUCFG and CSR, we are now able to boot Linux
kernel with Loongson-3A4000 CPU, so there is no point to restrict
CPU type to 3A1000 only, instead we just check for presence of
INSN_LOONGSON3A.
