Add a driver to read out the amount of memory from the DDR controller.
The decoding of the registers has been taken from U-Boot. Currently
supported are the RK3399 and the RK3568, but decoding should work on
other Rockchip SoCs as well.

Apparently, this was so far undocumented, but it's useful in some setups
where board type is detected dynamically. Document it.

barebox will warn about lack of these properties when network booting.
To make network booted barebox behave identically to flashed barebox,
let's unconditionally copy them from VideoCore FDT into fixed up FDT.

It shouldn't matter for now, but DMA API should always be called for the
physical device, i.e. the struct device underlying the struct pci_device.
This the Ethernet device interface parent, so use that instead.

We are using echo -e, so the \n in the string being echo'd are
interpreted. As -e is not POSIX and dash doesn't provide it,
we use a strange /usr/bin/env echo -e construct hoping that
whatever non-builtin echo is first in the search path supports -e.
As the new lines are just used to separate CPP directives, we can
just pass the directives as $(CPP) flags. This has the same result,
but is portable and avoids NixOS complaining when building barebox.

Clang doesn't like our implementation of CLOCKSOURCE_MASK:
common/clock.c:33:10: warning: shift count >= width of type [-Wshift-count-overflow]
.mask = CLOCKSOURCE_MASK(64),
^~~~~~~~~~~~~~~~~~~~
include/clock.h:8:63: note: expanded from macro 'CLOCKSOURCE_MASK'
#define CLOCKSOURCE_MASK(bits) (uint64_t)((bits) < 64 ? ((1ULL<<(bits))-1) : -1)
So the bits < 64 check we have is apparently not enough to suppress the
warning when built with clang.
Let's do what the kernel does and use GENMASK_ULL instead to get rid of
the last remaining warning when building ARCH=sandbox targettools_defconfig
with clang version 16.0.1.
Not functional change intended.

Now that a __dtb* reference automatically pulls in the IMD tag if
support is compiled in, we can drop all IMD_USED_OF and turn the macro
into a no-op until we remove it completely.
Theoretically, an out-of-tree board could reference a DT via IMD_USED_OF
and not actually reference it via __dtb_*_start. So instead of makign
IMD_USED_OF a no-top, let's print a warning for a few releases until
we remove it completely.

We currently require IMD_OF_USED to get the DT compatible into the
barebox image data meta section. As the PBL is already referencing the
DT to pass it along to barebox proper, let's add a reference from the DT
to the image data section to make IMD_OF_USED unnecessary.

We lack endianness conversion functions for Windows. Import them from
the public-domain portable_endian.h[1]. We skip the 64-bit XBox support
though as it's unlikely we'll need to run imx-usb-loader on that
particular game console.
While at it, only define min when it's undefined. This works around one
of the winapi headers indirectly included defining it.

Port the panel-mipi-dbi driver from the Linux kernel. It works with most
MIPI DBI compatible SPI panels.
This avoids adding a driver for every new MIPI DBI compatible controller
that is to be used by Barebox. The 'compatible' Device Tree property
with a '.bin' suffix will be used to load a firmware file that contains
the controller configuration.
Example (driver will load sainsmart18.bin):
display@0 {
compatible = "sainsmart18", "panel-mipi-dbi-spi";
...

Enable the dual-role support locally till we have upstream devicetree
support. By this patch and with the recent usb-otg patches from Sascha
usbgadget/fastboot does work now on the i.MX8MP-EVK as well.

The decision whether to build a 32bit or 64bit barebox has to be made
first before anything else, so this makes CONFIG_64BIT a toplevel option
without any further dependencies.
With this patch we will only present the SoCs/boards which are actually
supported by the selected code model in Kconfig.
Without this patch it was often possible to select 32bit boards on a
64bit build or vice versa, which resulted in a broken build.

So far we can enable support for 32bit and 64bit SoCs at the same time
which results in an unbuildable barebox. This is annoying, let the board
visibility depend on the selected code model.

We have different driver specific variants of functions polling for the
device ready in the tree. Add a common sdhci_wait_for_done() and use
it where appropriate. This fixes a few deficiencies with the driver
specific variants.
rk_sdhci_wait_for_done() didn't check the SDHCI_INT_TIMEOUT bit and
returned -EPERM instead when it ought to return -ETIMEDOUT. The core
tries to detect a SD card first and expects a -ETIMEDOUT for the setup
command when really a eMMC is connected. Only with a -ETIMEDOUT the core
tries to detect a eMMC next.
at91_sdhci_wait_for_done() returned the status instead of the expected
0 value for success.

Using dev_err() and friends in PBL results in undefined references.
Implement dev_printf() for PBL to avoid that. Just ignore the dev
argument here as it's likely not intialized in PBL.
