2023-08-31target/mips: Remove unused headers in lcsr_helper.cPhilippe Mathieu-Daudé
This files only access the address_space_ld/st API, declared in "exec/cpu-all.h", already included by "cpu.h". Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-Id: <20230828221314.18435-9-philmd@linaro.org>
2023-08-31target/helpers: Remove unnecessary 'qemu/main-loop.h' headerPhilippe Mathieu-Daudé
"qemu/main-loop.h" declares functions related to QEMU's main loop mutex, which these files don't access. Remove the unused "qemu/main-loop.h" header.

2023-07-10target/mips: Implement Loongson CSR instructionsJiaxun Yang
Loongson introduced CSR instructions since 3A4000, which looks similar to IOCSR and CPUCFG instructions we seen in LoongArch. Unfortunately we don't have much document about those instructions, bit fields of CPUCFG instructions and IOCSR registers can be found at 3A4000's user manual, while instruction encodings can be found at arch/mips/include/asm/mach-loongson64/loongson_regs.h from Linux Kernel. Our predefined CPUCFG bits are differ from actual 3A4000, since we can't emulate all CPUCFG features present in 3A4000 for now, we just enable bits for what we have in TCG.
