The following features are supported in this initial port: - UART (samsung-style) with earlycon support - Interrupts, including affinity and IPIs (Apple Interrupt Controller) - SMP (through standard spin-table support) - simplefb-based framebuffer - Devicetree for the Mac Mini (should work for the others too at this stage) See below for an overview of changes since v2. == Merge notes == This patchset depends on both the nVHE changes that are already in 5.12-rc1, as well as the FIQ support work currently being reviewed at [1]. A tree containing this patchset on top of the required dependencies is available at [2][3]. Alternatively, you may apply this series on top of Mark's tree at the arm64-fiq-20210302 tag [4][5]. This series is expected to be merged by Arnd via the SoC tree. Maintainers, please ack if you are happy with the patches. We will coordinate with Arnd and Mark on the FIQ series to make sure all that goes smoothly. This is marked RFT as it needs some basic testing on other on other ARM platforms; in particular the Samsung UART driver changes need to be tested, and the ioremap()/timer changes could use at least a smoke test on some other arm64 platform. I would appreciate any test reports.

An arm32 build has been smoke-tested in qemu with the smdkc210 machine, to test the samsung_tty changes on non-Apple (emulated) hardware. == Patch overview == - 01 Cope with CPUs stuck in VHE mode This is a follow-up to the recent nVHE/cpufeature changes in mainline by Mark, adding a workaround for the M1's lack of nVHE mode. - 02-03 Core platform DT bindings - 04-05 CPU DT bindings and MIDR defines - 06-07 Add interrupt-names support to the ARM timer driver This is used to cleanly express the lack of a secure timer; platforms in the past have used various hacks like dummy IRQs here. - 08-12 ioremap_np() (nGnRnE) support The fabric in these SoCs only supports nGnRnE accesses for standard MMIO, except for PCI ranges which use nGnRE. Linux currently defaults to the latter on ARM64, so this adds a new ioremap type and DT properties to automatically select it for drivers using OF and devm abstractions, under buses specified in DT. - 13-16 AIC (Apple Interrupt Controller) driver and support defines This also embeds FIQ handling for this platform. - 17 Introduce CONFIG_ARCH_APPLE & add it to defconfig - 18-25 Add Apple SoC support to the samsung_tty driver This includes several refactoring patches to be able to more cleanly introduce this, as well as a switch to devm_ioremap_resource to be able to use the nGnRnE support introduced above. Earlycon support is included with a special-case nGnRnE hack, as earlycon is too early to use the generic infrastructure. - 26 simple-framebuffer bindings for Apple (trivial) - 27 Add the initial M1 Mac Mini (j274) devicetree == About the hardware == These machines officially support booting unsigned/user-provided XNU-like kernels, with a very different boot protocol and devicetree format. We are developing an initial bootloader, m1n1 [1], to take care of as many hardware peculiarities as possible and present a standard Linux arm64 boot protocol and device tree. In the future, I expect that production setups will add U-Boot and perhaps GRUB into the boot chain, to make the boot process similar to other ARM64 platforms. The machines expose their debug UART over USB Type C, triggered with vendor-specific USB-PD commands. Currently, the easiest way to get a serial console on these machines is to use a second M1 box and a simple USB C cable [2]. You can also build a DIY interface using an Arduino, a FUSB302 chip or board, and a 1.2V UART-TTL adapter [3]. In the coming weeks we will be designing an open hardware project to provide serial/debug connectivity to these machines (and, hopefully, also support other UART-over-Type C setups from other vendors). Please contact me privately if you are interested in getting an early prototype version of one of these devices. A quickstart guide to booting Linux kernels on these machines is available at [4], and we are documenting the hardware at [5].
