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: gemini: select pin controller

2017-08-05T21:48:29+00:00

The Gemini needs its pin controller for the platform to work properly. Signed-off-by: Linus Walleij

ARM: gemini: select ARM_AMBA

2017-08-05T21:48:22+00:00

This selects the ARM_AMBA PrimeCell bus for the Gemini so we can use the PL08x DMA engine derivative FTDMAC020 through the combined PL08x driver. Signed-off-by: Linus Walleij

ARM: gemini: select the clock controller

2017-08-05T21:48:18+00:00

We have added a common clock framework clock controller for the Gemini SoC, let's put it to use. Signed-off-by: Linus Walleij

ARM: gemini: tag the arch as having reset controller

2017-08-05T21:48:12+00:00

This arch has a reset controller so make this selectable. Signed-off-by: Linus Walleij

ARM: gemini: don't select SERIAL_OF_PLATFORM

2017-03-24T21:12:42+00:00

We cannot select the option when SERIAL_8250 is not also set: warning: (ARCH_GEMINI) selects SERIAL_OF_PLATFORM which has unmet direct dependencies (TTY && HAS_IOMEM && SERIAL_8250 && OF) This removes the 'select' statement, requiring that users enable the option manually. Alternatively, we could make it a conditional 'select SERIAL_OF_PLATFORM if SERIAL_8250' or also select a handful of other symbols that it depends on.

ARM: gemini: select the right GPIO block

2017-03-22T11:14:37+00:00

We want to select the GPIO_FTGPIO010 symbol for the generic Faraday FTGPIO010 driver, not the old driver. Cc: Jonas Jensen Signed-off-by: Linus Walleij

ARM: gemini: select gemini poweroff

2017-03-18T20:57:28+00:00

It's especially annoying if the system cannot be properly powered down so select the poweroff driver from the Kconfig. Cc: Janos Laube Cc: Paulius Zaleckas Cc: Hans Ulli Kroll Cc: Florian Fainelli Signed-off-by: Linus Walleij

ARM: gemini: convert to ARMv4 multiplatform

2017-03-12T11:27:27+00:00

This converts the Gemini platform to ARMv4 multiplatform, deleting the local include directory, moving an idiomatic local idling function into the .machine_init() call and getting rid of the Makefile.boot finally.
