At minimum HWCAP_LOONGARCH_CRC32 and HWCAP_LOONGARCH_FPU are missing. I don't know how many of the other features are implemented in target/loongarch/.
HWCAP_LOONGARCH_LAM and HWCAP_LOONGARCH_UAL are need.
Missing ELF_PLATFORM, per the kernel's set_elf_platform(cpu, "loongarch").
OK, I will correct on next version. Thanks. Song Gao
