Apple M1 SoC platform bring-up
This series brings up initial support for the Apple M1 SoC, used in the
2020 Mac Mini, MacBook Pro, and MacBook Air models.
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)
== Merge notes ==
This tag is based on v5.12-rc3 and includes the following two
dependencies merged in:
* Tip of arm64/for-next/fiq: 3889ba70102e
This is a hard (build) dependency that adds support for FIQ
interrupts, which is required for this SoC and the included AIC
irqchip driver. It is already merged in the arm64 tree.
* From tty/tty-next: 71b25f4df984
This commit includes the Samsung UART changes that have already
been merged into the tty tree. It is nominally a soft dependency,
but if this series is merged first it would trigger devicetree
validation failures as the DT included in it depends on bindings
introduced in the tty tree.
There was a merge conflict here. It has been resolved the same
way gregkh resolved it in a later tty merge, and both tty-next
and torvalds/master merge cleanly with this series at this time.
This series additionally depends on the nVHE changes in [1] to boot,
but we are letting those get merged through arm64.
This has been tested on an Apple M1 Mac Mini booting to a framebuffer
and serial console, with SMP and KASLR, with an arm64 defconfig
(+ CONFIG_FB_SIMPLE for the fb). In addition, the AIC driver now supports
running in EL1, tested in UP mode only.
== 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.
We also have WIP/not merged yet support for loading kernels and
interacting via dwc3 usb-gadget, which works with a standard C-C or C-A
cable and any Linux host.
A quickstart guide to booting Linux kernels on these machines is
available at [4], and we are documenting the hardware at [5].

This implements the 'nonposted-mmio' boolean property. Placing this

is posted MMIO.
of_mmio_is_nonposted() performs this check to determine if a given

asm-generic/io.h: Add a non-posted variant of ioremap()
ARM64 currently defaults to posted MMIO (nGnRE), but some devices
require the use of non-posted MMIO (nGnRnE). Introduce a new ioremap()
variant to handle this case. ioremap_np() returns NULL on arches that
do not implement this variant.
sparc64 is the only architecture that needs to be touched directly,
because it includes neither of the generic io.h or iomap.h headers.
This adds the IORESOURCE_MEM_NONPOSTED flag, which maps to this
variant and marks a given resource as requiring non-posted mappings.
This is implemented in the resource system because it is a SoC-level
requirement, so existing drivers do not need special-case code to pick
this ioremap variant.
Then this is implemented in devres by introducing devm_ioremap_np(),
and making devm_ioremap_resource() automatically select this variant
when the resource has the IORESOURCE_MEM_NONPOSTED flag set.

This is a relatively low-cost AST2500-based Xeon E-2100/E-2200 series
mini-ITX board that we hope can provide a decent platform for OpenBMC
development.
This initial device-tree provides the necessary configuration for
basic BMC functionality such as host power control, serial console and
KVM support, and POST code snooping.

ARM: dts: mvebu: Add device tree for ATL-x530 Board
Add device tree file for x530 board. This has an Armada 385 SoC. Has
NAND-flash for user storage and SPI for booting. Covers majority of x530
and GS980MX variants.

Samsung DTS ARM changes for v5.13
1. Configure battery charger and front camera on GT-I9100 phone.
2. Fix in several boards the Maxim PMIC/MUIC/fuel gauge interrupt flags
to match real type of interrupt coming from the device.
3. Correct DTS with dtschema. This brings back the commit adding input
clock to CMU in Exynos4412 Odroid which was reverted some time ago
due to unsupported deferred probes (now supported and tested).

ARM: dts: clps711x: Add an empty chosen node to top level DTSI
Missing "chosen" node can cause issues when booting a kernel
with a boot-loader that doesn't create a chosen node if this
isn't present in the DTB since the decompressor relies on a
pre-existing chosen node to be available to insert the command
line and merge other ATAGS info.
