- Add various STM32MP1 fixes for serial, env, clk, board, i2c ...
- Add STM32MP1 DDR driver update:
These update introduce the DDR interactive mode described in:
https://wiki.st.com/stm32mpu/index.php/U-Boot_SPL:_DDR_interactive_mode
This mode is used by the CubeMX: DDR tuning tool.
https://wiki.st.com/stm32mpu/index.php/STM32CubeMX
The DDR interactive mode is NOT activated by default because
it increase the SPL size and slow down the boot time
(200ms wait added).

For STM32MP, the watchdog is based on DM and the function watchod_reset
call the function uclass_get_device(UCLASS_WDT) to found the driver
associated IWDG2.
As this reset is not mandatory in debug putc (the uart fifo will be
empty after some us), we can simplify the code by removing this call.
And this patch avoid issue when putc is called before initialization
of DM core, before the parsing of the device tree parsing and each
node bound to driver; that also avoid memory leak.

Like clk_get_by_index, there is requirement for
clk_get_by_index_nodev. In this case to make common
code functionalities for dev and nodev, clk_get_by_index
is trying to get the index of clock by passing ofnode
instead of actual dev like current gpio uclass does.
In these scenarios with current order of include files
the serial_sifive driver is unable to find CONFIG_ENV_SIZE.
In file included from arch/riscv/include/asm/u-boot.h:23:0,
from include/dm/of.h:10,
from include/dm/ofnode.h:12,
from include/clk.h:11,
from drivers/serial/serial_sifive.c:6:
include/environment.h:145:19: error: 'CONFIG_ENV_SIZE'
undeclared here (not in a function); did you mean 'CONFIG_CMD_XIMG'?
#define ENV_SIZE (CONFIG_ENV_SIZE - ENV_HEADER_SIZE)
So, fix consists of changing the order of include files
in serial_sifive.c to include first common.h file.

This patch adds an alterative SPL version of atmel_serial_enable_clk().
This enables the usage of this driver without full clock support (in
drivers and DT nodes). This saves some space in the SPL image.
Please note that this fixed clock support is only added to the SPL code
in the DM_SERIAL part of this file. All boards not using SPL & DM_SERIAL
should not be affected.
This patch also introduces CONFIG_SPL_UART_CLOCK for the fixed UART
input clock. It defaults to 132096000 for ARCH_AT91 but can be set to
a different value if needed.

The DM_FLAG_PRE_RELOC shall be enabled in SBSA PL011 uart driver
as this driver is used in NXP based SoCs
It is necessary to have Serial console running before relocation
The !CONFIG_IS_ENABLED(OF_CONTROL) [*] check is set as "workaround"
for DM problem : 4687919684e
This flag is set if board does not support device-tree and using
platform data, In DM Model either of device tree or platform data
can be used to fetch device configuration
It is possible to use SBSA UART with CONFIG_DM_SERIAL but witout
corresponding device tree description (OF_CONTROL)
Other board/SoCs have this flag set unconditionally

If _debug_uart_putc() is called before _debug_uart_init(), the
ns16550 debug uart driver hangs in a tight loop waiting for the
tx FIFO to get empty.
As this can happen via a printf sneaking in before the port calls
debug_uart_init(), introduce a config option to ignore characters
before the debug uart is initialized.
This is done by reading the baudrate divisor and aborting if is zero.
The Kconfig option is required as reading the baudrate divisor does
not seem to work for all ns16500 compatibles (which is why the last
attempt on this has been reverted in 1a67969a99).
Tested on socfpga_cyclone5_socrates.

Building U-Boot with CONFIG_PCI and CONFIG_DM_PCI enabled, but
CONFIG_SPL_PCI_SUPPORT disabled, results in following linker
error:
lib/built-in.o: In function `fdtdec_get_pci_bar32':
lib/fdtdec.c:305: undefined reference to `dm_pci_read_bar32'
fdtdec.c:305:(.text.fdtdec_get_pci_bar32+0x24): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `dm_pci_read_bar32'
This is because reference to dm_pci_read_bar32() remains in lib/fdtdec.c
while SPL build does not descend into drivers/pci directory in
drivers/Makefile if CONFIG_SPL_PCI_SUPPORT is not enabled.
Fix this by applying appropriate #define guards in lib/fdtdec.c.
It looks like ns16550.c has the same problem, so fixed that too.
To simplify this, CONFIG_SPL_PCI_SUPPORT is renamed to CONFIG_SPL_PCI
(enables use of CONFIG_IS_ENABLED() macro).

This reverts commit 6f57c34473d37b8da5e6a3764d0d377d748aeef1 since it
does not seem to work at least on rk3399.
The Rockchip Technical Reference Manual (TRM) for the rk3399 says the baud
rate prescaler register is readable only when USR[0] is zero. Since this
bit is defined as "reserved" in the socfpga cylcone5 TRM, let's rather
drop this than making the ns16550 debug uart more platform specific.

Many SoCs from MediaTek have a high-speed uart. This UART is compatible
with the ns16550 in legacy mode. It has extra registers for high-speed
mode which can reach a maximum baudrate at 921600.
However this UART will no longer be compatible if it's in high-speed mode.
Some BootROM of MediaTek's SoCs will change the UART into high-speed mode
and the U-Boot must use this driver to initialize the UART.

When a driver declares DM_FLAG_PRE_RELOC flag, it wishes to be
bound before relocation. However due to a bug in the DM core,
the flag only takes effect when devices are statically declared
via U_BOOT_DEVICE(). This bug has been fixed recently by commit
"dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in
lists_bind_fdt()", but with the fix, it has a side effect that
all existing drivers that declared DM_FLAG_PRE_RELOC flag will
be bound before relocation now. This may expose potential boot
failure on some boards due to insufficient memory during the
pre-relocation stage.
To mitigate this potential impact, the following changes are
implemented:
- Remove DM_FLAG_PRE_RELOC flag in the driver, if the driver
only supports configuration from device tree (OF_CONTROL)
- Keep DM_FLAG_PRE_RELOC flag in the driver only if the device
is statically declared via U_BOOT_DEVICE()
- Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for
drivers that support both statically declared devices and
configuration from device tree
