RELENG_7_0, Sony TX1XP:

  sdhci0: <TI XX21/XX11 SD> mem

  sdhci0: 3 slot(s) allocated

      vendor     = 'Texas Instruments (TI)'
      device     = 'PCIxx11/21 Integrated FlashMedia Controller'
      class      = mass storage
  sdhci0 at pci0:6:5:4:      class=0x080500 card=0x00000000 chip=0x8034104c rev=0x00 hdr=0x00
      vendor     = 'Texas Instruments (TI)'
      device     = '10981734 SDA Standard Compliant SD Host Controller'
      class      = base peripheral

This is an integrated SD and MemoryStick reader; sadly it doesn't
actually attach any usable devices.
