  commit 970f8de3e4645b47cbd6dcfe51e75c670cf666cd
  Author: Paul Durrant <paul.durrant@xxxxxxxxxx>
  Date:   Thu Mar 23 17:03:09 2017 +0000
  
      tools/firmware: use a canned config for seabios
      
      The use of seabios defconfig kills boot performance of Windows guests
      because the default is for the int13 handler to use PIO when accessing
      the emulated IDE device.
      
      By instead using a canned configuration with the ATA settings overridden
      to enable DMA access (and also wider PIO) boot performance is markedly
      improved without the need to use a different (and possibly not supported)
      device model.
      
      This patch adds the canned configuration into tools/firmware and modifies
      the Makefile rule to copy it into place.
