[PATCH v5 00/15] Support AMD Pensando Elba SoC

[Brad Larson]

From: Brad Larson <blarson@xxxxxxx>

This series enables support for AMD 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

This is a respin based on review inputs

1. Change to AMD Pensando instead of Pensando.

2. No reference to spidev in the device tree.  Add multi-function driver
   pensando-elbasr and sub-device reset-elbasr.

3. Rebase to linux-next tag next-20220609 5.19.0-rc1

4. Redo the email list after rebase and using scripts/get_maintainer.pl
