Get rid of hard-coded register offsets and widths. Instead provide a way
for pinctrl drivers to specify different pin bank register offsets and
widths. This in turn makes it possible to add support for new SoCs that
have registers with offset/width values different than generic ones
already available in pinctrl-exynos driver.
Offset constants (now unused in pinctrl-exynos.c) are moved to
pinctrl-exynos7420 driver, which is the single user of those constants.
The design of this patch follows Linux kernel pinctrl-exynos driver
design, in terms of added data structures and types. This patch doesn't
add support for any new SoCs and shouldn't introduce any functional
changes.

Rework pin_to_bank_base() function to obtain bank data structure by bank
name instead of getting bank base address by pin name, and rename it to

Pull request rng-2024-04-rc1
QEMU does not provide information in the device-tree if the ARMv8.5 RNDR
or the RISC-V Zkr RNG have been enabled on the command line.
In different parts of our code we assume that the first RNG device is the
one to be used. Therefore it is preferable to detect the availability of
said devices already in the bind method.
There has been a related discussion if the U_BOOT_DRVINFO() macro should be
used for architectural devices
(https://lore.kernel.org/u-boot/20231031125552.26698-1-heinrich.schuchardt@canonical.com/).
This aspect is not touched by this series.
The existence of devices should be checked in the bind method and not in
the probe method. Adjust the RISC-V Zkr RNG driver accordingly.
Use ENOENT (and not ENODEV) to signal that the device is not available.

Implement fdtdec_board_setup() auto-detection of ethernet PHY.
This uses properties of the hardware and pull resistor placement.
If GPIO1_16 RGMII_MDC is HIGH, then R530 (MX8MM eDM SBC) or
R390 (MX8MP eDM SBC) is populated. R530 or R390 is populated
only on boards with AR8031 PHY.
If GPIO1_16 RGMII_MDC is LOW, then the in-SoM pull down is the
dominant pull resistor. This is the case on boards with BCM54213PE
PHY.
In case AR8031 PHY is populated, the PHY MDIO address is 0, in
case BCM54213PE PHY is populated, the PHY MDIO address is 1, the
fdtdec_board_setup() is used to patch the correct address into
the U-Boot control DT.

At present this code allocates memory when writing the tables and
then unnecessarily adds another memory map when installing it.
Adjust the code to allocate the tables using the normal U-Boot
mechanism. This avoids doing an EFI memory allocation early in
U-Boot, which may use memory that would be overwritten by a
'load' command, for example.

Sandbox uses an API to map between addresses and pointers. This allows
it to have (emulated) memory at zero and avoid arch-specific addressing
details. It also allows memory-mapped peripherals to work.
As an example, on many machines sandbox maps address 100 to pointer
value 10000000.
However this is not correct for ACPI, if sandbox starts another program
(e.g EFI app) and passes it the tables. That app has no knowledge of
sandbox's address mapping. So to make this work we want to store
10000000 as the value in the table.
Add two new 'nomap' functions which clearly make this exeption to how
sandbox works.
This should allow EFI apps to access ACPI tables with sandbox, e.g. for
testing purposes.

address is not large enough.
Use an SMBIOS3 table in that case.
Note that we cannot use efi_allocate_pages() since this function has
nothing to do with EFI. There is no equivalent function to allocate
