93b55636b0 tools: kwboot: Allow any baudrate on Linux
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>.

ca272041c0 tools: kwboot: Support higher baudrates when booting via UART
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.

04ced0296e tools: kwboot: Round up header size to 128 B when patching
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.

SPI/NOR kwbimage may have destination address set to 0xFFFFFFFF, which
means that the image is not downloaded to DDR but rather it is executed

for A38x).

Currently if BootROM fails to respond with ACK/NAK to a xmodem block, we
will be waiting indefinitely for such response.

Make sure that we only wait at most 1 second (blk_rsp_timeo) for ACK/NAK
for each block in case non-xmodem text output is not being expected.
Interpret this timeout expiration as NAK, to try to send the block
again.

On the other hand, if timeout expires without ACK while some non-xmodem
output was already received (DDR training output, for example), we know
that the block was received, since the code is being executed, so in
this case exit with ETIMEDOUT.

48b3ea66ca tools: kwboot: Allow non-xmodem text output from BootROM only in a specific case
When sending image header / image data, BootROM does not send any
non-xmodem text output. We should therefore interpret unknown bytes in
the xmodem protocol as errors and resend current packet. This should
improve the transfer in case there are errors on the UART line.

Text output from BootROM may only happen after whole image header is
sent and before ACK for the last packet of image header is received.
In this case BootROM may execute code from the image, which may interact
with UART (U-Boot SPL, for example, prints stuff on UART).

Print received non-xmodem output from BootROM only in this case.
