The generic GPIO flags binding is shared across many drivers, some of
which need their own xlate function. Factor out the flag translation
code from gpio_xlate_offs_flags so it does not need to be duplicated.

This config is only used by three boards with this SOC. Most other
platforms derive this information from devicetree, and are unlikely
to ever need this config.
Moreover, it is confusing when Kconfig asks for this value under
"Support OPTEE images", but does not do anything with the value.
Move it to imx7 for those boards who still make use of it.

This value is not used by u-boot, and it should not. The load address
of an OPTEE image is defined by said image. Either a uImage or a FIT
will have a defined load address and entry point. Those values are the
correct ones, not CONFIG_OPTEE_LOAD_ADDR.
Commit f25006b96e ("optee: Add CONFIG_OPTEE_LOAD_ADDR") justifies
this config by requiring its presence in u-boot's .config for other
images as part of a larger build, claiming it is "the best way".
This argument is not persuasive. U-boot's configuration is driven by
platform requirements, not the other way around. It seems more likely
that the argument is conflating tooling issues with Kconfig. Yocto and
buildroot have excellent mechanisms for defining values across the
board (pun intended). u-boot's Kconfig is the wrong place to do it.
Furthermore, it is not "best" for u-boot because it hardcodes a value
which is then not used. In fact the load address that u-boot uses is
the one derived from the OPTEE image.
Confused yet? I sure was. To prevent future confusion, remove
CONFIG_OPTEE_LOAD_ADDR.

It is no longer used in u-boot. Information about the TZDRAM location
is usually available in the devicetree as "/reserved-memory/" nodes.
Because this isn't used, remove it.
Signed-off-by: Alexandru Gagniuc <mr.nuke.me@gmail.com>
The configs TZDRAM_BASE and TZDRAM_SIZE are expected to describe the
memory allocated to the OPTEE region. according to according to commit
c5a6e8bd00 ("optee: Add optee_verify_bootm_image()"). The TZDRAM is
with some limitations, described by "/reserved-memory" nodes in the
devicetree.
Consequently TZDRAM_BASE and TZDRAM_SIZE can point to imaginary
regions which have nothing to do with actual DRAM. They are not used
to configure the hardware or set up the Trust Zone Controller (TZC)
for OP-TEE -- the devicetree values are used instead.
When a valid OP-TEE image does not fall within the region described by
these configs, u-boot will refuse to load it. In fact, it mostly
serves to cause "bootm" to reject perfectly good OP-TEE images.
Ironically, someone has to correctly configure the devicetree for
TZDRAM, then go back and enter the same information in Kconfig for
"bootm". To remedy this, do not use TZDRAM_BASE and TZDRAM_SIZE in the
verification of OPTEE images.

The configuration CONFIG_OPTEE is defined 2 times:
1- in lib/optee/Kconfig for support of OPTEE images loaded by bootm command
2- in drivers/tee/optee/Kconfig for support of OP-TEE driver.
It is abnormal to have the same CONFIG define for 2 purpose;
and it is difficult to managed correctly their dependencies.
Moreover CONFIG_SPL_OPTEE is defined in common/spl/Kconfig
to manage OPTEE image load in SPL.
This definition causes an issue with the macro CONFIG_IS_ENABLED(OPTEE)
to test the availability of the OP-TEE driver.
This patch cleans the configuration dependency with:
- CONFIG_OPTEE_IMAGE (renamed) => support of OP-TEE image in U-Boot
- CONFIG_SPL_OPTEE_IMAGE (renamed) => support of OP-TEE image in SPL
- CONFIG_OPTEE (same) => support of OP-TEE driver in U-Boot
- CONFIG_OPTEE_LIB (new) => support of OP-TEE library
After this patch, the macro have the correct behavior:
- CONFIG_IS_ENABLED(OPTEE_IMAGE) => Load of OP-TEE image is supported
- CONFIG_IS_ENABLED(OPTEE) => OP-TEE driver is supported

This allows to use the watchdog in custom scripts but does not enforce

Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
To avoid the need of extra boot scripting on AM65x for loading a
watchdog firmware, add the required rproc init and loading logic for the
first R5F core to the watchdog start handler. In case the R5F cluster is
in lock-step mode, also initialize the second core. The firmware itself
is embedded into U-Boot binary to ease access to it and ensure it is
properly hashed in case of secure boot.
One possible firmware source is https://github.com/siemens/k3-rti-wdt.
The board is responsible for providing the firmware as additional
loadable via the U-Boot fit image. The driver will pick up its location
from /fit-images/k3-rti-wdt-firmware then.

This adds support for the IOT2050 Basic and Advanced devices. The Basic
used the dual-core AM6528 GP processor, the Advanced one the AM6548 HS
quad-core version.
Both variants are booted via a Siemens-provided FSBL that runs on the R5
cores. Consequently, U-Boot support is targeting the A53 cores. U-Boot
SPL, ATF and TEE have to reside in SPI flash.

The RX8025/RX8035 does not like having it's time registers
set byte-by-byte in separate I2C transactions.
From the note at the top of the file, it appears
target-dependent workarounds have been used in the
past for this.
Resolve this by setting the time registers in a single
I2C transaction.
As part of this, also ensure the '24/12' flag in the RTC
is reset before writing the date (instead of after), otherwise
the RX8035 will clear the seconds and minutes registers.
