Sata Support on Hummingboard

[Russell Haley]

Hey,

I've got the latest kernel with the changes to ahci.c, but I'm still not
seeing my ssd. I noticed the file imx6q.dtsi had the sata status as
disabled, so I changed that to enabled (?) and rebuilt the kernel again but
it didn't make any difference. This is all I'm seeing:

root at defcon3:~# ofwdump -p /soc/sata
Node 0x64a4: sata at 02200000
  compatible:
    66 73 6c 2c 69 6d 78 36 71 2d 61 68 63 69 00
    'fsl,imx6q-ahci'
  reg:
    02 20 00 00 00 00 40 00
  interrupts:
    00 00 00 00 00 00 00 27 00 00 00 04
  clocks:
    00 00 00 02 00 00 00 9a 00 00 00 02 00 00 00 bb 00 00 00 02
    00 00 00 69
  clock-names:
    73 61 74 61 00 73 61 74 61 5f 72 65 66 00 61 68 62 00
  status:
    6f 6b 61 79 00
    'okay'
  fsl,transmit-level-mV:
    00 00 04 01
  fsl,transmit-boost-mdB:
    00 00 0d 02
  fsl,transmit-atten-16ths:
    00 00 00 09
  fsl,receive-eq-mdB:
    00 00 0b b8

And nothing in the boot output about ahci or sata on simplebus or anything.
The values in the device tree file imx6q.dtsi are the same as the ones in
the Linux tree in the current kernel too.

Any thoughts?

Thanks,
Russ
