ARM: rework endianess selection

2022-04-08T15:20:54+00:00

Choosing big-endian vs little-endian kernels in Kconfig has not worked correctly since the introduction of CONFIG_ARCH_MULTIPLATFORM a long time ago. The problems is that CONFIG_BIG_ENDIAN depends on ARCH_SUPPORTS_BIG_ENDIAN, which can set by any one platform in the config, but would actually have to be supported by all of them. This was mostly ok for ARMv6/ARMv7 builds, since these are BE8 and tend to just work aside from problems in nonportable device drivers. For ARMv4/v5 machines, CONFIG_BIG_ENDIAN and CONFIG_ARCH_MULTIPLATFORM were never set together, so this was disabled on all those machines except for IXP4xx. As IXP4xx can now become part of ARCH_MULTIPLATFORM, it seems better to formalize this logic: all ARMv4/v5 platforms get an explicit dependency on being either big-endian (ixp4xx) or little-endian (the rest). We may want to fix ixp4xx in the future to support both, but it does not work in LE mode at the moment. For the ARMv6/v7 platforms, there are two ways this could be handled a) allow both modes only for platforms selecting 'ARCH_SUPPORTS_BIG_ENDIAN' today, but only LE mode for the others, given that these were added intentionally at some point. b) allow both modes everwhere, given that it was already possible to build that way by e.g. selecting ARCH_VIRT, and that the list is not an accurate reflection of which platforms may or may not work. Out of these, I picked b) because it seemed slighly more logical to me. Signed-off-by: Arnd Bergmann

ARM: socfpga: fix missing RESET_CONTROLLER

2022-02-07T09:54:42+00:00

The SocFPGA machine since commit b3ca9888f35f ("reset: socfpga: add an early reset driver for SoCFPGA") uses reset controller, so it should select RESET_CONTROLLER explicitly. Selecting ARCH_HAS_RESET_CONTROLLER is not enough because it affects only default choice still allowing a non-buildable configuration: /usr/bin/arm-linux-gnueabi-ld: arch/arm/mach-socfpga/socfpga.o: in function `socfpga_init_irq': arch/arm/mach-socfpga/socfpga.c:56: undefined reference to `socfpga_reset_init' Reported-by: kernel test robot Cc: Fixes: b3ca9888f35f ("reset: socfpga: add an early reset driver for SoCFPGA") Signed-off-by: Krzysztof Kozlowski Signed-off-by: Dinh Nguyen

ARM: socfpga: drop ARCH_SOCFPGA

2021-03-23T16:03:36+00:00

Simplify 32-bit and 64-bit Intel SoCFPGA Kconfig options by having only one for both of them. After conversion of all drivers to use the new ARCH_INTEL_SOCFPGA, the remaining ARM option can be removed. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Dinh Nguyen

2021-03-23T16:03:35+00:00

Simplify 32-bit and 64-bit Intel SoCFPGA Kconfig options by having only one for both of them. This the common practice for other platforms. Additionally, the ARCH_SOCFPGA is too generic as SoCFPGA designs come from multiple vendors. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Dinh Nguyen

ARM: socfpga: Drop unneeded select of PCI_DOMAINS_GENERIC

2020-05-15T21:27:38+00:00

Support for Altera SOCFPGA systems depends on ARCH_MULTI_V7, and thus on ARCH_MULTIPLATFORM. As the latter selects PCI_DOMAINS_GENERIC, there is no need for ARCH_SOCFPGA to select PCI_DOMAINS_GENERIC.

PCI: consolidate the PCI_DOMAINS and PCI_DOMAINS_GENERIC config options

2018-11-23T02:45:44+00:00

Move the definitions to drivers/pci and let the architectures select them. Two small differences to before: PCI_DOMAINS_GENERIC now selects PCI_DOMAINS, cutting down the churn for modern architectures. As the only architectured arm did previously also offer PCI_DOMAINS as a user visible choice in addition to selecting it from the relevant configs, this is gone now.

PCI: controller: Move PCI_DOMAINS selection to arch Kconfig

2018-06-26T20:37:37+00:00

Commit 51bc085d6454 ("PCI: Improve host drivers compile test coverage") added configuration options to allow PCI host controller drivers to be compile tested on all architectures. Some host controller drivers (eg PCIE_ALTERA) config entries select the PCI_DOMAINS config option to enable PCI domains management in the kernel. Now that host controller drivers can be compiled on all architectures, this triggers build regressions on arches that do not implement the PCI_DOMAINS required API (ie pci_domain_nr()): drivers/ata/pata_ali.c: In function 'ali_init_chipset': drivers/ata/pata_ali.c:469:38: error: implicit declaration of function 'pci_domain_nr'; did you mean 'pci_iomap_wc'? Furthemore, some software configurations (ie Jailhouse) require a PCI_DOMAINS enabled kernel to configure multiple host controllers without having an explicit dependency on the ARM platform on which they run. Make PCI_DOMAINS a visible configuration option on ARM so that software configurations that need it can manually select it and move the PCI_DOMAINS selection from PCI controllers configuration file to ARM sub-arch config entries that currently require it, fixing the issue.
