From: Nick Hawkins <[email protected]>
Changes since v4:
*Fixed version mismatch with patchset across all patches
*Fixed typos with ochi -> ohci echi -> ehci
*Adjusted Watchdog Kconfig file
*Adjusted various commit comments
*Removed un-necessary include file
*Updated outdated base revision to newer one to resolve merge
conflicts as well as pickup vendor binding change for hpe.
Changes since v3:
*Completely redid the dtsi file to represent architecture
*Reduced device tree size
*Rewrote the timer driver to start the watchdog driver due
to similar register region
*Made adjustments to timer
*Made adjustments to watchdog
*Changed gxp.yaml to hpe,gxp.yaml with changes
*Updated Maintainers to represent new file names
*Added hpe bindings to generic-ehci and generic-ohci
*Fixed clock architecture to be accurate
Changes since v2:
*Reduced size of changes, put them into patchset format
*Changed from txt->yaml
Changes since v1:
*Fixed 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.
