The PWM pins on North Bridge on Armada 37xx can be configured into PWM
or GPIO functions. When in PWM function, each pin can also be configured
to drive low on 0 and tri-state on 1 (LED mode).
The current definitions handle this by declaring two pin groups for each
pin:
- group "pwmN" with functions "pwm" and "gpio"
- group "ledN_od" ("od" for open drain) with functions "led" and "gpio"
This is semantically incorrect. The correct definition for each pin
should be one group with three functions: "pwm", "led" and "gpio".
Change the "pwmN" groups to support "led" function.
Remove "ledN_od" groups. This cannot break backwards compatibility with
older device trees: no device tree uses it since there is no PWM driver
for this SOC yet. Also "ledN_od" groups are not even documented.

tools: kwbimage: Remove v1 kwbimage SPL padding to CONFIG_SYS_U_BOOT_OFFS bytes
This padding depends on board config file and therefore it makes the
mkimage binary tool board specific, which is not correct. One cannot use
mkimage tool built as a result for board A to generate images for board
B, even if both A and B are on the same platform.
This CONFIG_SYS_U_BOOT_OFFS padding was needed when kwbimage v1 contained
SPL code which loaded U-Boot proper based on CONFIG_SYS_U_BOOT_OFFS,
instead of reading correct offset from kwbimage header.
Now that SPL code parses kwbimage header and deterinate correct offset,
there is no need for this CONFIG_SYS_U_BOOT_OFFS padding anymore.
By removing it we also reduce the size of SPL code and therefore also
decrease the final size of v1 kwbimage. This means there is more space
for U-Boot proper binary.

arm: mvebu: Load U-Boot proper binary in SPL code based on kwbimage header
Now that proper load and execution addresses are set in v1 kwbimage we
can use it for loading and booting U-Boot proper.
Use the new spl_parse_board_header() function to implement parsing the
kwbimage v1 header. Use information from this header to locate offset and
size of the U-Boot proper binary, instead of using the legacy U-Boot
header which is prepended to the U-Boot proper binary stored at fixed
offset. This has the advantage that we do not need to relay on legacy
U-Boot header anymore and therefore U-Boot proper binary can be stored at
any offset, as is the case when loading & booting U-Boot proper by
BootROM. The CONFIG_SYS_U_BOOT_OFFS option is therefore not used by SPL
code anymore.
Also allow to compile U-Boot SPL without CONFIG_SPL_SPI_FLASH_SUPPORT,
CONFIG_SPL_MMC_SUPPORT or CONFIG_SPL_SATA_SUPPORT set. In this case
BootROM is used for loading and executing U-Boot proper. This reduces the
size of U-Boot's SPL image. By default these config options are enabled
and so BootROM loading is not used. In some cases BootROM reads from SPI
NOR at lower speed than U-Boot SPL. So people can decide whether they
want to have smaller SPL binary at the cost of slower boot.
Therefore dependency on CONFIG_SPL_DM_SPI, CONFIG_SPL_SPI_FLASH_SUPPORT,
CONFIG_SPL_SPI_LOAD, CONFIG_SPL_SPI_SUPPORT, CONFIG_SPL_DM_GPIO,
CONFIG_SPL_DM_MMC, CONFIG_SPL_GPIO_SUPPORT, CONFIG_SPL_LIBDISK_SUPPORT,
CONFIG_SPL_MMC_SUPPORT, CONFIG_SPL_SATA_SUPPORT and
CONFIG_SPL_LIBDISK_SUPPORT is changed from strict to related "imply"
(which can be selectivelly turned off and causes booting via BootROM).
Options CONFIG_SYS_SPI_U_BOOT_OFFS,
CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR and
CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_DATA_PART_OFFSET have to to be set to
zero as they define the location where kwbimage header starts. It is the
location where BootROM expects start of the kwbimage from which it reads,
parses and executes SPL part. The same applies to option
CONFIG_SPL_SATA_RAW_U_BOOT_SECTOR, which has to be set to one.
Update all config files to set correct values of these options and set
CONFIG_SYS_U_BOOT_OFFS to the correct value - the offset where U-Boot

SPL: Add support for parsing board / BootROM specific image types
Platform specific BootROM may use its own image type for loading SPL or

This file does not correctly handle the various cases, sometimes
producing warnings about partition_basic_data_guid being defined but not
used. Fix it.
There was some discussion about adjusting Kconfig or making
HAVE_BLOCK_DEVICE a prerequisite for PARTITIONS, but apparently this is
not feasible. Such changes can be undertaken separate from the goal of
this series.

Makefile: Drop include/asm directory as well as symlink
At present when using 'make mrproper' on an out-of-tree build, a warning
is shown about include/asm being a directory. With old versions of U-Boot
it is a file, but more recently it has become a directory.
Remove this directory first, since that covers both cases.

cmd: setexpr: add format string handling
Add format string handling operator to the setexpr command.
It allows to use C or Bash like format string expressions to be
evaluated with the result being stored inside the environment variable
name.
setexpr <name> fmt <format> [value]...
The following example
setexpr foo fmt "%d, 0x%x" 0x100 ff
will result in $foo being set to "256, 0xff".

stm32mp1: spl: Configure TrustZone controller for OP-TEE
OP-TEE is very particular about how the TZC should be configured.
When booting an OP-TEE payload, an incorrect TZC configuration will
result in a panic.
Most information can be derived from the SPL devicetree. The only
information we don't have is the split between TZDRAM and shared
memory. This has to be hardcoded. The rest of the configuration is
fairly easy, and only requires 3 TZC regions. Configure them.

arm: stm32mp: Implement support for TZC 400 controller
The purpose of this change is to allow configuring TrustZone (TZC)
memory permissions. For example, OP-TEE expects TZC regions to be
configured in a very particular way. The API presented here is
intended to allow exactly that.
UCLASS support is not implemented, because it would not be too useful.
Changing TZC permissions needs to be done with care, so as not to cut
off access to memory we are currently using. One place where we can
use this is at the end of SPL, right before jumping to OP-TEE.

OP-TEE requires some particular setup, which is not needed for linux
or other payloads. Add a hook for platform-specific code to perform
any OP-TEE related configuration and initialization.
A weak function is used because it is symmetrical to other
spl_board_prepare_for_*() implementations. A solution to avoid the use
of weak functions would trivially apply to all these implementations.
However, re-designing this is beyond the scope of this patch.

In general, Falcon mode means we're booting a linux kernel directly.
With FIT images, however, an OP-TEE secure kernel can be booted before
linux. Thus, if the next stage is an IH_OS_TEE, this isn't necessarily
a problem.
Of course, a general solution would involve mmc_load_image_raw_os()
only loading the binary, and leaving the decision of suitability to
someone else. However, a rework of the boot flow is beyond the scope
of this patch. Accept IH_OS_TEE as a valid OS value.
