函数名称：load_ucode_bsp

函数原型：void __init load_ucode_bsp(void)

返回类型：void

参数：无

165  bool intel = true
167  如果非Probe for the CPUID instruction 则返回
170  cpuid_1_eax等于Native CPUID functions returning a single datum.
173  当:In early loading microcode phase on BSP, boot_cpu_data is not set up yet.* x86_cpuid_vendor() gets vendor id for BSP.* In 32 bit AP case, accessing boot_cpu_data needs linear address. To simplify恒等于X86_VENDOR_INTEL
174  如果x86_family(cpuid_1_eax)小于6则返回
176  退出
178  当:In early loading microcode phase on BSP, boot_cpu_data is not set up yet.* x86_cpuid_vendor() gets vendor id for BSP.* In 32 bit AP case, accessing boot_cpu_data needs linear address. To simplify恒等于X86_VENDOR_AMD
179  如果x86_family(cpuid_1_eax)小于0x10则返回
181  intel = false
182  退出
184  默认
185  返回
188  如果check_loader_disabled_bsp()则返回
191  如果intel则load_ucode_intel_bsp()
193  否则load_ucode_amd_bsp(cpuid_1_eax)
