The NVMe co-processor on the Apple M1 uses a DMA address filter called
SART for some DMA transactions. This adds a simple driver used to
configure the memory regions from which DMA transactions are allowed.

Unlike a real IOMMU, SART does not support any pagetables and can't be
implemented inside the IOMMU subsystem using iommu_ops.

It also can't be implemented using dma_map_ops since not all DMA
transactions of the NVMe controller are filtered by SART.
Instead, most buffers have to be registered using the integrated NVMe
IOMMU and we can't have two separate dma_map_ops implementations for a
single device.

Apple SoCs such as the M1 come with a simple DMA address filter called
SART. Unlike a real IOMMU no pagetables can be configured but instead
DMA transactions can be allowed for up to 16 paddr regions. The consumer
also needs special support since not all DMA allocations have to be
added to this filter.

In light of the recent controversy surrounding the (lack of)
maintenance of the in-tree DRBD driver, we have decided to add myself
as co-maintainer. This allows us to better distribute the workload and
reduce the chance of patches getting lost.

I will be keeping an eye on the mailing list in order to ensure that all
patches get the attention they need.

U-Boot uses environment variables for storing device setup data. It
usually needs to be accessed by a bootloader, kernel and often
user-space.

This binding allows describing environment data located in a raw flash
partition. It's treated as NVMEM device and can be reused later for
other storage devices.

Using DT should be cleaner than hardcoding & duplicating such info in
multiple places. Bootloader & kernel can share DTS and user-space can
try reading it too or just have correct data exposed by a kernel.

A custom "compatible" string allows system to automatically load
relevant NVMEM driver but phandle can be also used for reading raw
location.

Commit f8669f1d ("nvdimm/blk: Delete the block-aperture window driver")
removes the file drivers/nvdimm/blk.c, but misses to adjust MAINTAINERS.

Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a
broken reference.

The section LIBNVDIMM BLK: MMIO-APERTURE DRIVER refers to the driver in
blk.c, and some more generic nvdimm code in region_devs.c.

As the driver is deleted, delete the section LIBNVDIMM BLK: MMIO-APERTURE
DRIVER in MAINTAINERS as well.

The remaining file region_devs.c is still covered by the section LIBNVDIMM:
NON-VOLATILE MEMORY DEVICE SUBSYSTEM, and all patches to region_devs.c will
still reach the same developers as before.
