This series enables support for Pensando Elba SoC based platforms.
The Elba SoC has the following features:

- Sixteen ARM64 A72 cores
- Dual DDR 4/5 memory controllers
- 32 lanes of PCIe Gen3/4 to the Host
- Network interfaces: Dual 200GE, Quad 100GE, 50GE, 25GE, 10GE and
  also a single 1GE management port.
- Storage/crypto offloads and 144 programmable P4 cores.
- QSPI and EMMC for SoC storage
- Two SPI interfaces for peripheral management
- I2C bus for platform management
