When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

We have a large number of places where while we historically referenced
gd in the code we no longer do, as well as cases where the code added
that line "just in case" during development and never dropped it.

CONFIG_NAND_ZYNQ selects CONFIG_SYS_NAND_SELF_INIT, so the

Also, we can mark zynq_nand_init() as static and get rid

The goal of this patch is to clean up the code related to choosing SPL
MMC boot mode.
The spl_boot_mode() now is called only in spl_mmc_load_image() function,
which is only compiled in if CONFIG_SPL_MMC_SUPPORT is enabled.
To achieve the goal, all per mach/arch implementations eligible for

Putting board_nand_init() function inside NAND driver was not appropriate
due to it doesn't allow board vendor to customise their NAND

With SPL_LDSCRIPT moved to Kconfig (and this being a 'string' config
node), all the lingering definitions in header files will cause
warnings/errors due to the redefinition of the configuration item.
As we don't want to pollute the defconfig files (and values should
usually be identical for entire architectures), the defaults are moved
into Kconfig. Kconfig will always pick the first default that
matches, so please keep these values at the end of each file (to allow
any board-specific Kconfig, which will be included earlier) to
override with an unconditional default setting.

When using EFI_LOADER, we add a few special sections for runtime code and
data which get relocated on demand when executing a target OS.
These runtime structures need to get annotated properly in the linker script.
While we do that properly in the generic one, we missed out on the zynq
specific linker script.
This patch adds the EFI runtime section annotations into the zynq linker script
so that the efi loader code actually works on that platform.

The Zynq/ZynqMP boot.bin file contains a region for register initialization
data. Filling in proper values in this table can reduce boot time
(e.g. about 50ms faster on QSPI boot) and also reduce the size of
the SPL binary.
The table is a simple text file with register+data on each line. Other
lines are simply skipped. The file can be passed to mkimage using the
"-R" parameter.
It is recommended to add reg init file to board folder.

The SPL code already knows which boot device it calls the spl_boot_mode()
on, so pass that information into the function. This allows the code of
spl_boot_mode() avoid invoking spl_boot_device() again, but it also lets
board_boot_order() correctly alter the behavior of the boot process.
The later one is important, since in certain cases, it is desired that
spl_boot_device() return value be overriden using board_boot_order().

[add newly introduced zynq variant]
Signed-aff-by: Andreas Bießmann <andreas@biessmann.org>
The following changes are made to the clock API:
* The concept of "clocks" and "peripheral clocks" are unified; each clock
provider now implements a single set of clocks. This provides a simpler
conceptual interface to clients, and better aligns with device tree
clock bindings.
* Clocks are now identified with a single "struct clk", rather than
requiring clients to store the clock provider device and clock identity
values separately. For simple clock consumers, this isolates clients
from internal details of the clock API.
* clk.h is split so it only contains the client/consumer API, whereas
clk-uclass.h contains the provider API. This aligns with the recently
added reset and mailbox APIs.
* clk_ops .of_xlate(), .request(), and .free() are added so providers
can customize these operations if needed. This also aligns with the
recently added reset and mailbox APIs.
* clk_disable() is added.
* All users of the current clock APIs are updated.
* Sandbox clock tests are updated to exercise clock lookup via DT, and
clock enable/disable.
* rkclk_get_clk() is removed and replaced with standard APIs.
Buildman shows no clock-related errors for any board for which buildman
can download a toolchain.
test/py passes for sandbox (which invokes the dm clk test amongst
others).
