Add platform support for delta ag9032v2a CPU: Broadwell-DE ASIC: BMC56870 with <100Gx32 + 10Gx1> BMC: AST2520: - What I did add the new platform of delta ag9032v2a - How I did it 1.provide the QSFP and SWPLD attributes and create the virtual buses of I2C 2. provide the port configuration - How to verify it 1. psuutil.py 2. sfputil.py 3. bcmcd - Known issue The port LED is not ready. We noticed that BCM chip had the M0 FW initialization issue while bringing up SDK with "BRCM SAI ver: [3.5.2.3], OCP SAI ver: [1.4], SDK ver: [6.5.14]" and here is the information : root@sonic:/home/admin# bcmcmd "M0 status" M0 status 0:soc_iproc_data_send_wait: No response for msg 2 M0 FW is NOT Running M0 FW Version is 0.0 Host FW Version is 1.0 Host and M0 FW Versions do not match!!!
