Various hardware, like the Type-C PHY or the Thunderbolt/USB4 NHI, present on Apple SoCs need machine-specific tunables passed from our bootloader m1n1 to the device tree. Add generic helpers so that we don't have to duplicate this across multiple drivers.

Apple SoCs have various co-processors required for certain

peripherals to work (NVMe, display controller, etc.). This

driver adds support for the mailbox controller used to

communicate with those.

Apple SoCs such as the M1 come with various co-processors running
|
|
their proprietary RTKit operating system. This option enables support
|
|
for the protocol library used to communicate with those. It is used

by various client drivers.

Apple SART is a simple DMA address filter used on Apple SoCs such
|
|
as the M1. It is usually required for the NVMe coprocessor which does
|
|
not use a proper IOMMU.

Say 'y' here if you have an Apple SoC.
