[PATCH 0/6] x86: Correct timer overflow and add msr/cpuid commands

[Simon Glass]

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
