With CONFIG_DMA_BOUNCE_UNALIGNED_KMALLOC enabled, the arm64 kernel still
allocates the default SWIOTLB buffer (64MB) even if ZONE_DMA is disabled
or all the RAM fits into this zone. However, this potentially wastes a
non-negligible amount of memory on platforms with little RAM.
Reduce the SWIOTLB size to 1MB per 1GB of RAM if only needed for
kmalloc() buffer bouncing.

BPI-CM4
No change in functionality. Fixup adjustments.
BPI-M2S
The fan on the unit is constantly running. So lets set thermal
trip points and add the ability to control when we want it to
kick on. By default it is set to power on at 60*C.

rk322x has peripheral mode that is not working
really well, add various non-upstream patches
and timing adjustments that makes things a bit
more usable (mass storage and ethernet works,
uac isn't)
* meson-6.7: Copy patches from 6.6
Commit f852beca0a ("Switch meson64, bcm2711, sunxi, imx6, mvebu current to 6.6, edge to 6.7 and leave 6.1 for legecy") bump to linux 6.7 but forget to copy patches.
* meson-6.7: Refresh patches
* Add board BananaPi M4 Zero

* HACK: wrong DRAM size: add extra barrier in mctl_mem_matches
People report that this is fixed by adding another "dsb();" at
the beginning of the mctl_mem_matches() function.
