mb/ocp/deltalake: Add OCP Delta Lake mainboard
OCP Delta Lake server is a one socket server platform powered by Intel Cooper Lake Scalable Processor. The Delta Lake server is a blade of OCP Yosemite V3 multi-host sled. TESTED=Successfully booted on both YV3 config A Delta Lake server and config C Delta Lake server. The coreboot payload is Linux kernel plus u-root as initramfs. Below are the logs of ssh'ing into a config C deltalake server: jonzhang@devvm2573:~$ ssh yv3-cth root@ip's password: Last login: Mon Apr 20 21:56:51 2020 from [root@dhcp-100-96-192-156 ~]# lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 52 On-line CPU(s) list: 0-51 ...
