About RGMII mode setting of MAC0

[zhouyuanqing8 at outlook.com]

Hi,

    My name is Harley, I am currently developing an openbmc project based on the AST2500 chip. There are a few questions that need to be consulted. Please help me to answer them. Thank you very much!

    1、About RGMII mode setting of MAC0
    The current openbmc project and uboot code support 2 modes: MAC0 uses NCSI, MAC2 uses RGMII, but my board uses MAC0 RGMII. How can I simply configure this to complete this work, or do I have to modify aspeednic.c and add the new patch file under the directory meta-phosphor/aspeed-layer/recipes-bsp/u-boot/files ?

    2、There are lot of recipes under directory meta-phosphor, How does bitbake choose specific recipes? I read the manual of bitbake and the project of openbmc, and I didn't find a way to choose. openbmc has many recipes, we can't use them all。

    3、There are many common recipes under openbmc / meta-phosphor, is there any documentation about the architecture and detailed implementation principles of each recipe? For example, chassis power control.


Harley
