Re: [U-Boot] [PATCH 07/15] x86: Don't touch IA32_APIC_BASE MSR on Intel Quark

Intel Quark processor core provides an integrated Local APIC but does not support the IA32_APIC_BASE MSR. As a result, the Local APIC is always globally enabled and the Local APIC base address is fixed at 0xfee00000. Attempting to access the IA32_APIC_BASE MSR causes a general protection fault.
