Ls2088a is new introduced arm-based soc with sata support with
following features:
1. Complies with the serial ATA 3.0 specification and the AHCI 1.3.1
specification
2. Contains a high-speed descriptor-based DMA controller
3. Supports the following:
a. Speeds of 1.5 Gb/s (first-generation SATA), 3 Gb/s
(second-generation SATA), and 6 Gb/s (third-generation SATA)
b. FIS-based switching
c. Native command queuing (NCQ) commands
d. Port multiplier operation
e. Asynchronous notification
f. SATA BIST mode
