Both dummy.nbytes and dummy.buswidth may be zero. By not checking
the later, it is possible to trigger division by zero and a crash.
This does happen with tiny SPI NOR framework in SPL. Fix this by
adding the check and returning zero dummy bytes in such a case.

This allows to use the watchdog in custom scripts but does not enforce
that the OS has to support it as well.

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.
Full integration into a bootable image can be found on
https://github.com/siemens/meta-iot2050

Prepares for the addition of the IOT2050 board which is based on the TI
AM65x. The board comes in four variants, Basic and Advanced, each as
product generation 1 (SR1.0) and 2 (SR2.x), so there are separate dts
files needed. Furthermore, the SPL has its own device tree.

defined(CONFIG_DM_PCI_COMPAT)
The weak definition of pci_skip_dev from drivers/pci/pci_common.c is not
under CONFIG_DM_PCI_COMPAT, and that definition needs a previous
function prototype declaration to avoid W=1 build warnings.
That prototype is not available due to it being under CONFIG_DM_PCI_COMPAT,

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.
Tested on Traverse Ten64 (NXP LS1088A) with RX8035.

The A38x platform supports more baudrates than just those defined by the
Bn constants, and some of them are higher than the highest Bn baudrate
(the highest is 4 MBd while A38x support 5.15 MBd).
On Linux, add support for arbitrary baudrates. (Since there is no
standard POSIX API to specify arbitrary baudrate for a tty device, this
change is Linux-specific.)
We need to use raw TCGETS2/TCSETS2 or TCGETS/TCSETS ioctls with the
BOTHER flag in struct termios2/termios, defined in Linux headers
<asm/ioctls.h> (included by <sys/ioctl.h>) and <asm/termbits.h>. Since
these headers conflict with glibc's header file <termios.h>, it is not
possible to use libc's termios functions and we need to reimplement them
via ioctl() calls.
Note that the Bnnn constants from <termios.h> need not be compatible
with Bnnn constants from <asm/termbits.h>.

Add support for uploading the boot image (the data part only) at higher
baudrate than the standard one.
The kwboot utility already has -B option, but choosing other baudrate
than the standard one (115200 Bd) can only work for debug mode, not for
booting the device. The BootROM for kwboot supported platforms (Orion,
Kirkwood, Dove, Discovery, AXP, A37x, A38x, A39x) cannot change the
baudrate when uploading boot image via the Xmodem protocol, nor can it
be configured via strapping pins.
So instead we add this support by injecting baudrate changing code into
the kwbimage v1 header as a new optional binary extension. This code is
executed by BootROM after it receives the whole header. The code sends
the magic string "$baudratechange\0" just before changing the baudrate
to let kwboot know that it should also change it. This is because the
injected code is run as the last binary extension, and we do not want
to loose possible output from other possible binary extensions that
came before it (in most cases this is U-Boot SPL).
We also inject the code before the payload (the data part of the image),
to change the baudrate back to the standard value, in case the payload
does not reset UART.
This change improves boot time via UART significantly (depending on the
chosen baudrate), which is very useful when debugging.

The beginning of image data must be sent in a separate xmodem block;
the block must not contain end of header with the beginning of data.
Therefore we need to ensure that the image header size is a multiple of
xmodem block size (which is 128 B).
Read the file into a malloc()ed buffer of enough size instead of
mmap()ing it. (If we are going to move the data, most of the pages will
be dirty anyway.) Then move the payload if header size needs to be
increased.
