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.

2021-05-02target/mips: Move TCG source files under tcg/ sub directoryPhilippe Mathieu-Daudé
To ease maintenance, move all TCG specific files under the tcg/ sub-directory. Adapt the Meson machinery. The following prototypes: - mips_tcg_init() - mips_cpu_do_unaligned_access() - mips_cpu_do_transaction_failed() can now be restricted to the "tcg-internal.h" header.

2021-05-02target/mips: Move helper_cache() to tcg/sysemu/special_helper.cPhilippe Mathieu-Daudé
Move helper_cache() to tcg/sysemu/special_helper.c. The CACHE opcode is privileged and is not accessible in user emulation. However we get a link failure when restricting the symbol to sysemu. For now, add a stub helper to satisfy linking, which abort if ever called.
