This series corrects an overflow of the timer which happens on QEMU on newer hardware. It also adds commands to read/write CPU ID registers and machine-status registers (MSRs).
Simon Glass (6): x86: Show the CPU vendor in bdinfo x86: Ensure the CPU identity exists for timer init x86: Avoid timer-clock overflow x86: Sync up tsc_timer with Linux x86: Add a cpuid command x86: Add msr command
