Unless you have a spare Apple Silicon machine, getting access to
the serial port on Apple Silicon machines requires special
hardware. Given that most machines come with a built-in screen
the framebuffer is likely to be the most convenient output device
for most users. While U-Boot will output to both serial and
framebuffer, OSes might not. Therefore set stdout-path to point
at /chosen/framebuffer when a keyboard is connected to the machine.
This behaviour can be overridden by setting the "stdout" variable
in the U-Boot environment. I addition to that keep the serial
console as the default when running under the m1n1 hypervisor.
The m1n1 hypervisor virtualizes the serial port such that it
can be easily accessed from any other machine with a USB port.

A big part is the DM pinctrl driver, which allows us to get rid of quite
some custom pinmux code and make the whole port much more robust. Many
thanks to Samuel for that nice contribution! There are some more or less
cosmetic warnings about missing clocks right now, I will send the trivial
fixes for that later.
Another big chunk is the mkimage upgrade, which adds RISC-V and TOC0
(secure images) support. Both features are unused at the moment, but I
have an always-secure board that will use that once the DT lands in the
kernel.
On top of those big things we have some smaller fixes, improving the
I2C DM support, fixing some H6/H616 early clock setup and improving the
eMMC boot partition support.
The gitlab CI completed successfully, including the build test for all
161 sunxi boards. I also boot tested on a A64, A20, H3, H6, and F1C100
board. USB, SD card, eMMC, and Ethernet all work there (where applicable).
Create a do-nothing driver for each sunxi pin controller variant.
Since only one driver can automatically bind to a DT node, since the
GPIO driver already requires a manual binding process, and since the
pinctrl driver needs access to some of the same information, refactor
the GPIO driver to be bound by the pinctrl driver. This commit should
cause no functional change.

These functions are intended to support detecting semihosting and
falling back gracefully to alternative implementations. The test starts
by making semihosting call. SYS_ERRNO is chosen because it should not
mutate any state. If this semihosting call results in an exception
(rather than being caught by the debugger), then the exception handler
should call disable_semihosting() and resume execution after the call.
Ideally, this would just be part of semihosting by default, and not a
separate config. However, to reduce space ARM SPL doesn't include
exception vectors by default. This means we can't detect if a
semihosting call failed unless we enable them. To avoid forcing them to
be enabled, we use a separate config option. It might also be possible
to try and detect whether a debugger has enabled (by reading HDE from
DSCR), but I wasn't able to figure out a way to do this from all ELs.
This patch just introduces the generic code to handle detection. The
next patch will implement it for arm64 (but not arm32).

This adds a boot method for loading the next stage from the host. It is
mostly modeled off of spl_load_image_ext. I am not really sure why/how
spl_load_image_fat uses three different methods to load the image, but
the simple case seems to work OK for now.
To control the presence of this boot method, we add a config symbol.
While we're at it, we update the original semihosting config symbol.
I think semihosting has some advantages of other forms of JTAG boot.
Common other ways to boot from JTAG include:
- Implementing DDR initialization through JTAG (typically with dozens of
lines of TCL) and then loading U-Boot. The DDR initialization
typically uses hard-coded register writes, and is not easily adapted
to different boards. BOOT_DEVICE_SMH allows booting with SPL,
leveraging U-Boot's existing DDR initialization code. This is the
method used by NXP's CodeWarrior IDE on Layerscape processors (see
AN12270).
- Loading a bootloader into SDRAM, waiting for it to initialize DDR, and
then loading U-Boot. This is tricky, because the debugger must stop the
boot after the bootloader has completed its work. Trying to load
U-Boot too early can cause failure to boot. This is the method used by
Xilinx with its Zynq(MP) processors.
- Loading SPL with BOOT_DEVICE_RAM and breaking before SPL loads the
image to load U-Boot at the appropriate place. This can be a bit
tricky, because the load address is dependent on the header size. An
elf with symbols must also be used in order to stop at the appropriate
point. BOOT_DEVICE_SMH can be viewed as an extension of this process,
where SPL automatically stops and tells the host where to place the
image.

So far the FVP model just supports booting through semihosting, so by
loading files from the host the model is running on. This allows for
quick booting of new kernels (or replacing DTBs), but prevents more
featureful boots like using UEFI.
Enable the distro_boot feature, and provide a list of possible boot
sources that U-Boot should check:
- For backwards compatibility we start with semihosting, which gets its
commands migrated from CONFIG_BOOTCOMMAND into the distro_boot
infrastructure. This is also slightly tweaked to fail graceful in case
the required files could not be found.
- Next we try to use a user provided script, that could be easily
placed into memory using the model command line.
- Since we gained virtio support with the enablement of OF_CONTROL,
let's check virtio block devices next. This is where UEFI boot can
be easily used, for instance by providing a distro installer .iso
file through virtio-blk.
- Networking is now provided by virtio as well, so enable the default
PXE and DHCP boot flows, mostly because we can.

The defconfigs for the Arm Juno board and the FVP model are quite large,
setting a lot of platform-fixed variables like SYS_TEXT_BASE.
As those values are not really a user choice, let's provide default
values for them in our Kconfig file, so a lot of cruft can be removed
from the defconfig files.
This also moves the driver selection out of there, since this is again
not something a user should really decide on. Instead we allow users to
enable or disable subsystems, and select the appropriate drivers based
on that in the Kconfig file.

The FVP base model is relying on a DT for Linux operation, so there is
no reason we would need to rely on hardcoded information for U-Boot.
Letting U-Boot use a DT will open up the usage of actual peripherals,
beyond the support for semihosting only.
Enable OF_CONTROL in the Kconfig, and use the latest dts files from
Linux. Depending on whether we use the boot-wrapper or TF-A, there is
already a DTB provided or not, respectively.
To cover the boot-wrapper, we add an arm64 Linux kernel header, which
allows the boot-wrapper to treat U-Boot like a Linux kernel. U-Boot will
find the pointer to the DTB in x0, and will use it.
Even though TF-A carries a DT, at the moment this is not made available
to non-secure world, so to not break users, we use the U-Boot provided
DTB copy in that case. For some reason TF-A puts some DT like structure
at the address x0 is pointing at, but that is very small and doesn't
carry any hardware information. Make the code to ignore those small DTBs.

At the moment we define three "VExpress64" boards in arch/arm/Kconfig,
plus have a second Kconfig file in board/armltd/Kconfig.
One of those three boards is actually bogus (TARGET_VEXPRESS64_AEMV8A),
that stanza looks like being forgotten in a previous cleanup.
To remove the clutter from the generic Kconfig file, just define some
ARCH_VEXPRESS64 symbol there, enable some common options, and do the
board/model specific configuration in the board/armltd Kconfig file.
That allows to streamline and fine tune the configuration later, and
to also pull a lot of "non user choices" out of the defconfigs.

The way board/keymile/Kconfig is written protects the options there from
being parsed on non-keymile platforms. We cannot however safely source
this file from multiple locations. This does not manifest as a problem
currently as there are no choice statements inside of this file (nor the
sub-Kconfig files it sources). However, moving some target selection to
one of these files exposes the underlying problem. Rework things so
that we have this file sourced in arch/Kconfig.

Commit 7945caf22c ("arm: sunxi: Enable SPI/SPI-FLASH support for A64")
selected CONFIG_SPI by default on all Allwinner A64 boards, even though
only 4 out of the 14 A64 boards have a SPI flash chip. All other SoCs
had to manually select DM_SPI and friends, even though they are a
platform property (the sunxi SPI driver is DM_SPI only).
Clean this up to allow easy selection of SPI flash support in U-Boot
proper, by selecting DM_SPI and DM_SPI_FLASH *if* CONFIG_SPI is
selected, for *all* Allwinner SoCs. This simplifies the defconfig for
two Libretech boards already.
Also remove the forced CONFIG_SPI from the A64 Kconfig, instead let the
four boards which allow SPI booting select this explicitly.
Any board wishing to support SPI flash in U-Boot proper now just defines
CONFIG_SPI and CONFIG_SPI_FLASH_<vendor> in its defconfig, Kconfig takes
care of the rest.

According to their TRMs, Cortex ARMv7 CPUs with SMP support require the
ACTLR.SMPEN bit to be set as early as possible, before any cache or TLB
maintenance operations are done. As we do those things still in start.S,
we need to move the SMPEN bit setting there, too.
This introduces a new ARMv7 wide symbol and code to set bit 6 in ACTLR
very early in start.S, and moves sunxi boards over to use that instead
of the custom code we had in our board.c file (where it was called
technically too late).
In practice we got away with this so far, because at this point all the
other cores were still in reset, so any broadcasting would have been
ignored anyway. But it is architecturally cleaner to do it early, and
we move a core specific piece of code out of board.c.
This also gets rid of the ARM_CORTEX_CPU_IS_UP kludge I introduced a few
years back, and moves the respective logic into the new Kconfig entry.
