Most drivers use these access methods but a few do not. Update them.
In some cases the access is not permitted, so mark those with a FIXME tag
for the maintainer to check.

There might be hardware configurations where 64-bit data accesses
to NVMe registers are not supported properly. This patch removes
the readq/writeq so always two 32-bit accesses are used to read/write
64-bit NVMe registers, similarly as it is done in Linux kernel.
This patch fixes operation of NVMe devices on RPi4 Broadcom BCM2711 SoC
based board, where the PCIe Root Complex, which is attached to the
system through the SCB bridge.
Even though the architecture is 64-bit the PCIe BAR is 32-bit and likely
the 64-bit wide register accesses initiated by the CPU are not properly
translated to a sequence of 32-bit PCIe accesses.
nvme_readq(), for example, always returns same value in upper and lower
32-bits, e.g. 0x3c033fff3c033fff which lead to NVMe devices to fail
probing.
This fix is analogous to commit 8e2ab05000ab ("usb: xhci: Use only
32-bit accesses in xhci_writeq/xhci_readq").

This reverts commit 828d32621686aec593076d16445d39b9b8d49c05.
This change revers code which asserting PERST# signal when unloading
driver. Driver's remove callback is still there as it is used for other
functionality.
Asserting PERST# signal prior booting kernel is causing that A3720 boards
(Turris MOX and Espressobin) with stable Linux kernel versions 4.14 and
4.19 are not able to detect some PCIe cards (e.g. Compex WLE200 and WLE900)
and anymore. When PERST# signal is not asserted these cards are detected
correctly. As this is regression for existing stable Linux kernel versions
revert this problematic change in U-Boot.
To make cards working with OpenWRT 4.14 kernel it is needed to disable link
training prior booting kernel, which is already done in driver's remove
callback.
Described issue is in Linux kernel pci aardvark driver which is (hopefully)
fixed in latest upstream versions. Latest upstream versions should be able
to initialize PCIe bus and detects cards independently of the link training
and PERST# signal state.
So with this change, U-Boot on A3720 boards should be able to boot OpenWRT
4.14 kernel, stable 4.14 and 4.19 kernels and also latest mainline kernels.

A recent change to unify the flattree/livetree code introduced a small
size increase in SPL on some boards. For example SPL code size for
px30-core-ctouch2-px30 increased by 40 bytes.
To address this we can take advantage of the fact that some of the ofnode
functions are only called a few times in SPL, so it is worth inlining
them.
Add new Kconfig options to control this. These functions are not inlined
for U-Boot proper, since this increases code size.

Currently, when different spi slaves claim the bus consecutively using
spi_claim_bus(), spi_set_speed_mode() will only be executed on the first
two calls, leaving the bus in a bad state starting with the third call.
This patch drops spi_slave->speed member and adds caching of bus
speed/mode in dm_spi_bus struct. It also updates spi_claim_bus() to call
spi_set_speed_mode() if either speed or mode is different from what the
bus is currently configured for. Current behavior is to only take into
account the speed, but not the mode, which seems wrong.

Some buses have their own rules which require assigning sequence numbers
with a bus-specific algorithm. For example, PCI requires that sub-buses
are numbered higher than their parent buses, meaning effectively that
parent buses must be numbered only after all of their child buses have
been numbered.
Add a uclass flag to indicate that driver model should not assign sequence
numbers. In this case, the uclass must do it.

At present each device has two sequence numbers, with 'req_seq' being
set up at bind time and 'seq' at probe time. The idea is that devices
can 'request' a sequence number and then the conflicts are resolved when
the device is probed.
This makes things complicated in a few cases, since we don't really know
what the sequence number will end up being. We want to honour the
bind-time requests if at all possible, but in fact the only source of
these at present is the devicetree aliases. Since we have the devicetree
available at bind time, we may as well just use it, in the hope that the
required processing will turn out to be useful later (i.e. the device
actually gets used).
Add a new 'sqq' member, the bind-time sequence number. It operates in
parallel to the old values for now. All devices get a valid sqq value,
i.e. it is never -1.
Drop an #ifdef while we are here.
