Changes since v2:
*Reduced size of changes, put them into pathset format
Changes since v1:
*Fix compiler warnings
The GXP is the HPE BMC SoC that is used in the majority
of HPE Generation 10 servers. Traditionally the asic will
last multiple generations of server before being replaced.
Info about SoC:
HPE GXP is the name of the HPE Soc. This SoC is used to implement
many BMC features at HPE. It supports ARMv7 architecture based on
the Cortex A9 core. It is capable of using an AXI bus to which
a memory controller is attached. It has multiple SPI interfaces
to connect boot flash and BIOS flash. It uses a 10/100/1000 MAC
for network connectivity. It has multiple i2c engines to drive
connectivity with a host infrastructure. The initial patches
enable the watchdog and timer enabling the host to be able to
boot.

This looks much better already, thanks for following the normal
submission procedures. With the timing for the merge window, this
is now too late for 5.18, but let's try to get it into 5.19 then.
