Implements support for the Eswin eic7700 SoC sata controller.
Provides basic functionality to initialize and manage the sata
controller for the eic7700 SoC. Integrates with the Linux AHCI subsystem
for standardized SATA host control and scalability.
Supported chips:
Eswin eic7700 SoC.
Test:
I tested this patch on the Sifive HiFive Premier P550 (which uses the EIC7700 SoC),
Ensure the hard drive is properly connected via the SATA interface on the hardware,
and confirm that the SATA controller within the chip can read/write to the hard drive
normally. The SATA driver patch is working properly.
