mohicks · htejun · commit 29200f12a116 · 2015-03-02T12:08:43.000-05:00

would look like:

fsl-sata ffe18000.sata: Sata FSL Platform/CSB Driver init
ata1: FORCE: PHY spd limit set to 1.5Gbps
ata1: SATA max UDMA/133 irq 74
ata1: Signature Update detected @ 0 msecs
ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 310)
