commit: 65f83802b7 "serial: 16550: Add getfcr accessor"
breaks u-boot commandline working with long commands
sending to the board.
Since the above patch, you have to setup the fcr register.
For board/archs which enable OF_PLATDATA, the new field
fcr in struct ns16550_platdata is not filled with a
default value ...
This leads in not setting up the uarts fifo, which ends
in problems, when you send long commands to u-boots
commandline.
Detected this issue with automated tbot tests on am335x
based shc board.
The error does not popup, if you type commands. You need
to copy&paste a long command to u-boots commandshell
(or send a long command with tbot)
Possible boards/plattforms with problems:

./arch/arm/mach-tegra/board.c

ISW_ENTRY_ADDR is used to set this address for AM43xx based SoCs
for similar reasons. Add this same logic for AM33xx devices.

When TI_SECURE_DEV_PKG is not defined we warn that the file '*_HS' was
not generated but generate an unsigned one anyway, first fix this
warning to say that it was generated but not secured.
When the user then exports TI_SECURE_DEV_PKG after getting this warning,
and tries to re-build, 'make' will detect the build artifacts as
unchanged and so assume they do not need to be re-generated. This causes
it to fail to sign the files and it will pack unsigned files into the
final image, even though TI_SECURE_DEV_PKG is now correctly defined and
working.
Fix this by using FORCE on the targets causes them to be re-run even if
the dependent files have not changed.
This then causes another issue. We currently rename the signed dtb files
to overwrite the non-signed ones. We do this so the 'mkimage' tool gives
the packaged dtb sections the correct name. If we do not rename the files
then SPL will not find them during boot.
Fix this by renaming the dtb files by appending _HS to the end of the
filename, after the ".dtb", this causes them to still be named correctly
in the FIT blob.

Since entry_point and load_addr are addresses, they should be
represented as longs to cover the whole address space and to avoid
warning when compiling the SPL in 64-bit.
Also adjust debug prints to add the 'l' specifier, where needed.

This patch adds support to update the device-tree blob to adjust the
DSP and IVA DPLL clocks pertinent to the selected OPP choice, with
the default being OPP_NOM. The voltage settings are done in u-boot,
but the actual clock configuration itself is done in kernel because
of the following reasons:
1. SoC definition constraints us to NOT to do dynamic voltage
scaling ever after the initial avs0 setting in bootloader
- so the voltage must be set in bootloader.
2. The voltage level must be set even if the IP blocks like
GPU/DSP are unused.
3. The IVA, GPU and DSP DPLLs are not essential for u-boot functionality,
and similar DPLL clock configuration code has been cleaned up in
v2014.10 u-boot release. See commit, 02c41535b6 ("ARM: OMAP4/5:
Remove dead code against CONFIG_SYS_CLOCKS_ENABLE_ALL").
The non-essential DPLLs are configured within the kernel during
the clock init step when parsing the device tree and creating
the clock devices. This approach meets both the u-boot and kernel
needs.

Redefine the macros used to define the voltage values and the
efuse register offsets based on OPP for all the voltage domains.
This is done using Kconfig macros that can be set in a defconfig
or selected during a config step. This allows a voltage domain
to be configured/set to a corresponding voltage value depending
on the OPP selection choice.
The Kconfig choices have been added for MPU, DSPEVE, IVA and GPU
voltage domains, with the MPU domain restricted to OPP_NOM. The
OPP_OD and OPP_HIGH options will be added when the support for
configuring the MPU clock frequency is added. The clock
configuration for other voltage domains is out of scope in
u-boot code.
The CORE voltage domain does not have separate voltage values
and efuse register offset at different OPPs, while the MPU
voltage domain only has different efuse register offsets for
different OPPs, but uses the same voltage value. Any different
choices of OPPs for voltage domains on common ganged-rails
is automatically taken care to select the corresponding
highest OPP voltage value.

It can be expected that different paper spins of a SoC can have

secure_tee_install is used to install and initialize a secure TEE OS such as
Linaro OP-TEE into the secure world. This function takes in the address
where the signed TEE image is loaded as an argument. The signed TEE image
consists of a header (struct tee_header), TEE code+data followed by the
signature generated using image signing tool from TI security development
package (SECDEV). Refer to README.ti-secure for more information.
This function uses 2 new secure APIs.
1. PPA_SERV_HAL_TEE_LOAD_MASTER - Must be called on CPU Core 0. Protected
memory for TEE must be reserved before calling this function. This API
needs arguments filled into struct ppa_tee_load_info. The TEE image is
authenticated and if there are no errors, the control passes to the TEE
entry point.
2. PPA_SERV_HAL_TEE_LOAD_SLAVE - Called on other CPU cores only after
a TEE_LOAD_MASTER call. Takes no arguments. Checks if TEE was
successfully loaded (on core 0) and transfers control to the same TEE
entry point.
The code at TEE entry point is expected perform OS initialization steps
and return back to non-secure world (U-Boot).
