Hi,

We have a nice devinfo command which can print the devices as a tree.
Let's make more use of it and make spi/network/console devices children
of the corresponding hardware devices.
Also, when a file under /dev/ is associated to a device, print the
start and end with the information.

On a i.MX51 babbage board we change from:

devices:
|----imx_serial0
|----cs0
|----mem0 (ram0)
|----imx_iim0 (imx_iim_bank0, imx_iim_bank1, imx_iim_bank2, imx_iim_bank3, imx_iim_bank4, imx_iim_bank5, imx_iim_bank6, imx_iim_bank7)
|----ramfs0
|----devfs0
|----mem1 (defaultenv)
|----mem2 (mem)
|----fec_imx0
|----miidev0 (phy0)
|----eth0
|----imx-esdhc0
|----mci0
|----disk0
|----imx_spi0
|----mc13892-spi0 (mc13892)

to this:

devices:
`---- imx_serial0
     `---- cs0
`---- mem0
     `---- 0x00000000-0x1fffffff: /dev/ram0
`---- imx_iim0
     `---- 0x00000000-0x0000001f: /dev/imx_iim_bank0
     `---- 0x00000000-0x0000001f: /dev/imx_iim_bank1
     `---- 0x00000000-0x0000001f: /dev/imx_iim_bank2
     `---- 0x00000000-0x0000001f: /dev/imx_iim_bank3
     `---- 0x00000000-0x0000001f: /dev/imx_iim_bank4
     `---- 0x00000000-0x0000001f: /dev/imx_iim_bank5
     `---- 0x00000000-0x0000001f: /dev/imx_iim_bank6
     `---- 0x00000000-0x0000001f: /dev/imx_iim_bank7
`---- ramfs0
`---- devfs0
`---- mem1
     `---- 0x00000000-0x00001e08: /dev/defaultenv
`---- mem2
     `---- 0x00000000-0xfffffffe: /dev/mem
`---- fec_imx0
     `---- miidev0
          `---- 0x00000000-0x0000003f: /dev/phy0
     `---- eth0
`---- imx-esdhc0
     `---- mci0
          `---- disk0
`---- imx_spi0
     `---- mc13892-spi0
          `---- 0x00000000-0x000000ff: /dev/mc13892


Sascha Hauer (7):
      mci: embed mci_dev into mci_host instead of allocating it seperately
      net: make the ethernet device a child of the hardware device
      net mii: add a parent pointer to miidevs and set it to the hardware device
      console: make console device a child of the hardware device
      mci: parent fixups
      spi: make the spi devices children of the parent bus
      devinfo: beautify output
