This has not been needed since parent information was added and we started
using indicies for references to other drivers instead of pointers. It was
kept around in the expectation that it might be needed later.
However with the latest updates, it doesn't seem likely that we'll need
this in the foreseeable future.
Drop dm_populate_phandle_data() from dtoc and driver model.

We use the U_BOOT_ prefix (i.e. U_BOOT_DRIVER) to declare a driver but
in every other case we just use DM_. Update the alias macros to use the
DM_ prefix.
We could perhaps rename U_BOOT_DRIVER() to DM_DRIVER(), but this macro
is widely used and there is at least some benefit to indicating it us a
U-Boot driver, particularly for code ported from Linux. So for now, let's
keep that name.

In the spirit of using the same base name for all of these related macros,
rename this to have the operation at the end. This is not widely used so
the impact is fairly small.

The current macro is a misnomer since it does not declare a device
directly. Instead, it declares driver_info record which U-Boot uses at
runtime to create a device.
The distinction seems somewhat minor most of the time, but is becomes
quite confusing when we actually want to declare a device, with
of-platdata. We are left trying to distinguish between a device which
isn't actually device, and a device that is (perhaps an 'instance'?)
It seems better to rename this macro to describe what it actually is. The
macros is not widely used, since boards should use devicetree to declare
devices.
Rename it to U_BOOT_DRVINFO(), which indicates clearly that this is
declaring a new driver_info record, not a device.

The #define of one struct to another has been around for a while. It
confuses dtoc and makes it think that struct spi_flash does not exist.
Make a few changes to improve things while we wait for migration to be
completed:
- Move the 'struct spi_flash' to column 1 so dtoc scans it
- Remove the #define when compiling dt-platdata.c
- Update the strange mtd_get/set_of_node() functions
- Use struct spi_nor in the drivers, so dtoc sees the correct struct

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 8e2ab05000 ("usb: xhci: Use only
32-bit accesses in xhci_writeq/xhci_readq").

This reverts commit 828d326216.
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.
