ARM: mach-hpe: Rework support and directory structure

2025-09-15T13:07:38+00:00

Having a platform need a mach-* directory should be seen as a negative, it means the platform needs special non-standard handling. ARM64 support does not allow mach-* directories at all. While we may not get to that given all the non-standard architectures we support, we should still try to get as close as we can and reduce the number of mach directories. The mach-hpe/ directory and files, provides just one "feature": having the kernel print the machine name if the DTB does not also contain a "model" string (which they always do). To reduce the number of mach-* directories let's do without that feature and remove this directory. Note, we drop the l2c_aux_mask = ~0 line, but this is safe as the fallback GENERIC_DT machine has that as the default.

ARM: hpe: Introduce the HPE GXP architecture

2022-05-18T12:05:53+00:00

The GXP is the HPE BMC SoC that is used in the majority of current generation HPE 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 whicha 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. There currently are no public specifications but this process is being worked. Previously there was a requirement to reset the EHCI controller for the asic to boot. This functionality has been moved to the u-boot bootloader.
