ARM: omap1: enable multiplatform

2022-06-03T18:48:53Z

With all the header files out of the way, and the clock driver converted to the common framework, nothing stops us from building OMAP together with the other platforms. As usual, the decompressor support is a victim here, and is only available when CONFIG_DEBUG_LL is configured for the particular board. Acked-by: Tony Lindgren Signed-off-by: Arnd Bergmann

Patch series from Nick Hawkins: "The GXP is the HPE BMC SoC that is used in the majority of HPE current generation 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.

Pull ARMv4T/v5 multiplatform support from Arnd Bergmann: "This series has been 12 years in the making, it mostly finishes the work that was started with the founding of Linaro to clean up platform support in the kernel. The largest change here is a cleanup of the omap1 platform, which is the final ARM machine type to get converted to the common-clk subsystem. All the omap1 specific drivers are now made independent of the mach/*.h headers to allow the platform to be part of a generic ARMv4/v5 multiplatform kernel. The last bit that enables this support is still missing here while we wait for some last dependencies to make it into the mainline kernel through other subsystems. The s3c24xx, ixp4xx, iop32x, ep93xx and dove platforms were all almost at the point of allowing multiplatform kernels, this work gets completed here along with a few additional cleanup. At the same time, the s3c24xx and s3c64xx are now deprecated and expected to get removed in the future. The PXA and OMAP1 bits are in a separate branch because of dependencies. Once both branches are merged, only the three Intel StrongARM platforms (RiscPC, Footbridge/NetWinder and StrongARM1100) need separate kernels, and there are no plans to include these" * tag 'arm-multiplatform-5.19-1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (61 commits) ARM: ixp4xx: Consolidate Kconfig fixing issue ARM: versatile: Add missing of_node_put in dcscb_init ARM: config: Refresh IXP4xx config after multiplatform ARM: omap1: add back omap_set_dma_priority() stub ARM: omap: fix missing declaration warnings ARM: omap: fix address space warnings from sparse ARM: spear: remove include/mach/ subdirectory ARM: davinci: remove include/mach/ subdirectory ARM: omap2: remove include/mach/ subdirectory integrator: remove empty ap_init_early() ARM: s3c: fix include path MAINTAINERS: omap1: Add Janusz as an additional maintainer ARM: omap1: htc_herald: fix typos in comments ARM: OMAP1: fix typos in comments ARM: OMAP1: clock: Remove noop code ARM: OMAP1: clock: Remove unused code ARM: OMAP1: clock: Fix UART rate reporting algorithm ARM: OMAP1: clock: Fix early UART rate issues ARM: OMAP1: Prepare for conversion of OMAP1 clocks to CCF ARM: omap1: fix build with no SoC selected ...

ARM: 9206/1: A9: Add ARM ERRATA 764319 workaround (Updated)

2022-05-20T11:33:48Z

Enable the workaround for the 764319 Cortex A-9 erratum. CP14 read accesses to the DBGPRSR and DBGOSLSR registers generate an unexpected Undefined Instruction exception when the DBGSWENABLE external pin is set to 0, even when the CP14 accesses are performed from a privileged mode. The work around catches the exception in a way the kernel does not stop execution with the use of undef_hook. This has been found to effect the HPE GXP SoC.

ARM: hpe: Introduce the HPE GXP architecture

2022-05-18T12:05:53Z

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.

ARM: pxa: convert to multiplatform

2022-05-07T20:56:17Z

PXA is now ready to be built into a single kernel with all the other ARMv5 platforms, so change the Kconfig bit to finish it off. The mach/uncompress.h support is the last bit that goes away, getting replaced with the normal DEBUG_LL based approach. Signed-off-by: Arnd Bergmann

ARM: pxa: remove support for MTD_XIP

2022-05-07T20:56:17Z

Using MTD-XIP does not work on multiplatform kernels because it requires SoC specific register accesses to be done from low-level flash handling functions in RAM while the rest of the kernel sits in flash. I found no evidence of anyone still actually using this feature, so remove it from PXA to avoid spending a lot of time on actually making it work. Signed-off-by: Arnd Bergmann

ARM: pxa: move plat-pxa to drivers/soc/

2022-05-07T20:56:16Z

There are two drivers in arch/arm/plat-pxa: mfp and ssp. Both of them should ideally not be needed at all, as there are proper subsystems to replace them. OTOH, they are self-contained and can simply be normal SoC drivers, so move them over there to eliminate one more of the plat-* directories.
