函数名称：__load_microcode_amd

函数原型：static enum ucode_state __load_microcode_amd(u8 family, const u8 *data, size_t size)

返回类型：enum ucode_state

参数：

类型参数名称
u8family
const u8 *data
size_tsize
806  fw等于data
809  offset等于install_equiv_cpu_table(data, size)
810  如果非offset则返回:UCODE_ERROR
813  fw加等于offset
814  size减等于offset
816  如果fw不等于UCODE_UCODE_TYPE则
817  打印错误信息("invalid type field in container file section header\n")
818  free_equiv_cpu_table()
819  返回:UCODE_ERROR
822  当size大于0循环
823  crnt_size等于0
826  ret等于Return a non-negative value even if some of the checks failed so that* we can skip over the next patch. If we return a negative value, we* signal a grave error like a memory allocation has failed and the* driver cannot continue functioning normally
827  如果ret小于0则返回:UCODE_ERROR
830  fw加等于crnt_size加SECTION_HDR_SIZE
831  size减等于crnt_size加SECTION_HDR_SIZE
834  返回:UCODE_OK
