This patch adds a Device Feature List (DFL) bus driver for the Altera SPI Master controller. The SPI master is connected to an Intel SPI Slave to Avalon Bridge inside an Intel MAX10 BMC Chip.

This driver supports SPI Controller for HiSilicon Kunpeng SoCs. This driver supports SPI operations using FIFO mode of transfer. DMA is not supported, and we just use IRQ mode for operation completion notification. Only ACPI firmware is supported.

This driver likely also supports earlier (RTL8196) and later (RTL93xx) SoCs. The SPI hardware in these SoCs is specifically intended for connecting NOR bootflash chips, and only used for that in dozens of examined devices. However boiled down to basics, it's really just a half-duplex SPI controller. The hardware appears to have a vestigial second chip-select control, but it hasn't been seen in the wild and is thus not supported.

The CSR SiRF prima2/atlas platforms are getting removed, so this driver is no longer needed.

Uwe Kleine-König <uwe.kleine-koenig@pengutronix.de>: From: Uwe Kleine-König <uwe.kleine-koenig@pengutronix.de> Hello, there are no known active users of the efm32 platform. Given that the only machine that is supported has only 4 MiB of RAM its use is also quite limited. Back then it served as the platform to develop ARMv7-M support in Linux which was quite fun and still is a blissful memory. Still given that the code serves no purpose and this probably won't change anytime soon, remove all platform support. I'm unsure what to do with the device tree bindings. Should we delete them, too?

Pull ARM SoC platform updates from Olof Johansson:
"SoC changes, a substantial part of this is cleanup of some of the
older platforms that used to have a bunch of board files.
In particular:
- Remove non-DT i.MX platforms that haven't seen activity in years,
it's time to remove them.
- A bunch of cleanup and removal of platform data for TI/OMAP
platforms, moving over to genpd for power/reset control (yay!)
- Major cleanup of Samsung S3C24xx and S3C64xx platforms, moving them
closer to multiplatform support (not quite there yet, but getting
close).
There are a few other changes too, smaller fixlets, etc. For new
platform support, the primary ones are:
- New SoC: Hisilicon SD5203, ARM926EJ-S platform.
- Cpufreq support for i.MX7ULP"
