[meta-freescale] i.MX6 - PCIe not detecting some devices in Linux 3.14.28

[ansaris]

Hi Nikolay,

Thank you for your prompt input.

My PCIe device is a SSD SATA only and it is connected in mini-pcie slot.
With Linux 3.10.53_1.0.0-GA BSP, the same device is getting detected and 
it is not detecting in Linux 3.10.53_1.0.0-GA.

Thank You
Regards,
Ansari
