Enable an existing simple framebuffer node in the Linux kernel device
tree and the add the associated reserved memory node to preserved the
resources (clock, memory) used by the stm32 video driver to display
the splashscreen = background in exlinux.conf file.
These resources will be released by the Linux driver only when the
associated driver is ready to avoid transition issues during the Linux
kernel initialization between U-Boot splash screen and the final display.

In some part of STM32MP15 support the CONFIG_TFABOOT can be replaced
by other config: CONFIG_ARMV7_PSCI and CONFIG_ARM_SMCCC.
This patch also simplifies the code in cpu.c, stm32mp1_ram.c and
clk_stml32mp1.c as execution of U-Boot in sysram (boot without SPL and
without TFA) is not supported: the associated initialization code is
present only in SPL.
This cleanup patch is a preliminary step to support SPL load of OP-TEE
in secure world, with SPL in secure world and U-Boot in no-secure world.

When a push-button is released and PA13/PA14 are defined as input (high-Z)
the LED should not be active as the circuit is open but a small current
leak through PCB or push-button close the circuit and allows a small LED
bias giving erroneous level voltage.
So it is recommended to activate an internal pull-up in order to clearly
fix the voltage at PA13/PA14 when button is released and to wait
a short delay before to read the GPIO value only when the pull-up is

the instance of boot device provided by the ROM code; the mmc instance

This patch allows to override this selection for the support of customer

USB-C power supply which are Power Delivery compliant (USB-PD) are able
to provide different voltage/current (for example 5V/3A 9V/3A 12V/2.25A...)
In this case, the power supply need to negotiate the voltage/current to
use with the device using CC1/CC2 USB-C signals.
If this negotiation occurs during ADC measurement (done also on CC1/CC2
USB-C signals) some ADC acquisition can be corrupted which cause wrong
power supply current detection.
To avoid this, the power supply current detection algorithm is updated
as following:
- perform an ADC measurement, if a 3A current is detected, continue the
boot process.
- else, wait 20ms (max tPDDebounce duration) to ensure that USB-PD
negotiation is done and perform another ADC measurement.

Update kernel load address for FIT examples to avoid relocation:
- Kernel example uses Image.gz with U-Boot gzip decompression
at final kernel location 0x0xC0008000.
- Copro example loads zImage at a correct location (0xC4000000),
to avoid zImage relocation before decompression by kernel code.
An other solution to avoid zImage relocation is to align
the kernel load and entry address with the real location in FIT
(the relocation of zImage is skipped in U-Boot bootm command for
identical address) but it is less flexible because this offset
depends on FIT content:

The Linux coding style guide (Documentation/process/coding-style.rst)
clearly says:
It's a **mistake** to use typedef for structures and pointers.
Besides, using typedef for structures is annoying when you try to make
headers self-contained.
Let's say you have the following function declaration in a header:
void foo(bd_t *bd);
This is not self-contained since bd_t is not defined.
To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h>
#include <asm/u-boot.h>
void foo(bd_t *bd);
Then, the include direcective pulls in more bloat needlessly.
If you use 'struct bd_info' instead, it is enough to put a forward
declaration as follows:
struct bd_info;
void foo(struct bd_info *bd);
Right, typedef'ing bd_t is a mistake.
I used coccinelle to generate this commit.
The semantic patch that makes this change is as follows:
