Subject: [PATCH v4 00/11] ARM: Introduce HPE GXP Architecture
Date:   Wed, 20 Apr 2022 10:01:14 -0500
Message-Id: <20220420150114.47356-1-nick.hawkins@hpe.com>
Precedence: bulk

From: Nick Hawkins <nick.hawkins@hpe.com>

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

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. Based on feedback from the device tree gxp-timer now
 creates a gxp-wdt child because of similar register region.
