In order to do SATA compliance tests, add the bist mode
sysfile callback to generate kinds of test patterns.
- Add the "ahci-imx.bist=1" into kernel command line to
register the bist mode enable callback.
- Use "echo <pattern_#> /sys/devices/.../ahci_bist_pattern"
to generate the responding test pattern.
- Use "cat /sys/devices/.../ahci_bist_pattern" to check
the current pattern configuration.
NOTE:
LBP 0, LFTP 1, MFTP 2, HFTP 3.
- Adjust the TX-DEEMP and COMINT to pass the compliance tests.
