To quote the author:
These patches will use bounce buffers when VIRTIO_F_IOMMU_PLATFORM
feature is in a virtio device.
This feature can be tested with qemu with -device virtio-iommu-pci. So
that when a -device virtio-blk-pci with iommu_platform=true, it will
uses the bounce buffer instead.
Devices advertising the VIRTIO_F_IOMMU_PLATFORM feature require
platform-specific handling to configure their DMA transactions.
When handling virtio descriptors for such a device, use bounce
buffers to ensure that the underlying buffers are always aligned
to and padded to PAGE_SIZE in preparation for platform specific
handling at page granularity.

The pages backing the virtqueues for virtio PCI devices are not freed
on reset, despite the virtqueue structure being freed as part of the
driver '->priv_auto' destruction at ->remove() time.
Call virtio_pci_del_vqs() from virtio_pci_reset() to free the virtqueue
pages before freeing the virtqueue structure itself.

The MSMC fixup is something we do based on SoC, not based on the board.
So this fixup does not belong in the board files. Move this to the
mach-k3 common file so that it does not have to be done in each board
that uses these SoCs.
We use ft_system_setup() here instead of ft_board_setup() since it is no
longer board level. Enable OF_SYSTEM_SETUP in the configurations that use
this to keep functionality the same.
