usb: ehci: Do not use memset on dma coherent memory ...

memset is an optimized operation that at least on ARM64 may only be
called on cached memory, see 32e8842c40 ("ARM: lib64: Make string
functions aware of MMU configuration"). To avoid crashes in the ehci
driver we no longer call memset on memory allocated with
dma_alloc_coherent(), but use a simple memzero32 function instead.

ARM: Layerscape: setup icids for the IOMMU ...

The Isolation Context Identifiers (icid) have to be configured in the
hardware and communicated to the Kernel via device tree fixups. This
adds the missing bits and pieces to make the IOMMU work under Linux.

As of Linux-5.5 the SMMU doesn't work out of the box. This series has
been tested in conjunction with this Kernel series:

net: fsl-fman: Do not put hardware in reset before Linux start ...

Linux depends on the icid values configured in the DPAA. Do not put
the hardware into reset in order to preserve the register values.
Without this, the IOMMU doesn't work properly.

include/soc/fsl: Make struct ccsr_qman v3 specific ...

struct ccsr_qman is ifdeffed for different versions of this structure.
CONFIG_SYS_FSL_QMAN_V3 is not defined which means we happen to use
the wrong version on LS1046a. Hardcode it to the v3 version to make
it work on LS1046a and rename it to ccsr_qman_v3 to make it obvious
that it needs a change on non v3 versions.

ARM: nxp-imx8mq-evk: fix second stage booting ...

If the whole image already resides in DRAM, e.g. by starting the
image via the bootm handler we try to load the piggydata from storage,
which may well be different from our expected piggydata, already
present in DRAM.

Fix this by avoiding the special piggydata load function, but instead
load the whole image after DRAM is up and just replace the PBL part to
ensure we are still running the HAB validated code after TF-A hands
back control to our code in DRAM.

ARM: rpi mailbox: Use non interruptible timeout ...

This makes sure that during a mailbox transfer no other mailbox transfer
is started. This happens on a raspberrypi3 where one GPIO on the
firmware GPIO controller (which is controlled via mailbox) is registered
as a heartbeat LED. With this it can happen that during a mailbox
transfer the poller which drives the heartbeat LED is triggered in
is_timeout() which results in corrupted transfers.
