Merge tag 'arm-soc-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC updates from Arnd Bergmann:
"SoC specific code is generally used for older platforms that don't
(yet) use device tree to do the same things.
- Support is added for i.MXRT10xx, a Cortex-M7 based microcontroller
from NXP. At the moment this is still incomplete as other portions
are merged through different trees.
- Long abandoned support for running NOMMU ARMv4 or ARMv5 platforms
gets removed, now the Arm NOMMU platforms are limited to the
Cortex-M family of microcontrollers
- Two old PXA boards get removed, along with corresponding driver
bits.
- Continued cleanup of the Intel IXP4xx platforms, removing some
remnants of the old board files.
- Minor Cleanups and fixes for Orion, PXA, MMP, Mstar, Samsung
- CPU idle support for AT91
- A system controller driver for Polarfire"

This is the preferred method due to speed but it - limits the system to just 64MB of PCI memory. This can be - problematic if using video cards and other memory-heavy devices. - - 2) If > 64MB of memory space is required, the IXP4xx can be - configured to use indirect registers to access the whole PCI - memory space. This currently allows for up to 1 GB (0x10000000 - to 0x4FFFFFFF) of memory on the bus. The disadvantage of this - is that every PCI access requires three local register accesses - plus a spinlock, but in some cases the performance hit is - acceptable. In addition, you cannot mmap() PCI devices in this - case due to the indirect nature of the PCI window. - - By default, the direct method is used.
