Dear Chanh, Thank you for the patch. Am 28.02.23 um 11:28 schrieb Chanh Nguyen:
Support the mac3 (RGMII4) as an NC-SI stack instead of an MDIO PHY. The OCP slot #0 and OCP slot #1 use a common the BMC_NCSI signal,
*the* seems a leftover.
so we use only one of them at the same time. The OCP slot #0 will be enabled by PCA9539's setting by default. Also, enable the OCP Auxiliary Power during booting.
Is there a reason not to make this a separate commit? Kind regards, Paul
