Not true. You can use the mini PCIe serdes as SATA directly if you
configure it as such. You only need to invert the serdes Rx pair
polarity. This is the default configuration for the Clearfog GT-8K CON3
mini-PCIe slot (CP1, lane #0) in current mainline U-Boot. I verified
that this setup works on Clearfog GT-8K.
This patch would break mini PCIe direct SATA.
