Some sunxi boards ship with SPI flash, which allows booting through the
BootROM. We cover this functionality by a separate SPL "mini" driver.
Separately we have a proper DM_SPI driver for U-Boot proper, which
provides access to the SPI flash through the "sf" command. That allows
to update the firmware on the SPI flash, also to store the environment
there.
However only very few boards actually enable support for U-Boot proper,
even though that would work and the SPL part is configured.
Use the cleaned up configuration scheme to enable SPI flash on those
boards which mention a SPI flash in their .dts, or which use the SPL SPI
support.
Out of the box this would enable storing the environment on the SPI
flash, and allows people to read or write the flash from U-Boot, for
instance to update the SPI flash when booted via an SD card.
For this to actually work there must be a "spi0" alias in the DT, which
most boards are missing. But this should be addressed separately.

Currently we only support to load the environment from raw MMC or FAT
locations on Allwinner boards. With the advent of SPI flash we probably
also want to support using the environment there, so we need to become
a bit more flexible.
Change the environment priority function to take the boot source into
account. When booted from eMMC or SD card, we use FAT or MMC, if
configured, as before.
If we are booted from SPI flash, we try to use the environment from
there, if possible. The same is true for NAND flash booting, although
this is somewhat theoretical right now (as untested).
This way we can use the same image for SD and SPI flash booting, which
allows us to simply copy a booted image from SD card to the SPI flash,
for instance.

To allow loading and storing the environment from SPI flash, adjust the
raw offset variables for Allwinner boards to make sense there.
U-Boot (including SPL and other blobs) is loaded from the beginning of
SPI flash, so move the environment location as far back as possible, to
not create unnecessary limits. As those offsets are shared with (now
mostly unused) raw MMC environment, we should respect the common one
megabyte limit, which also makes sense on SPI flash.
So limit the environment for those raw locations to 64KB, and place it
just below 1MB (@960KB).
Those values are currently unused, unless someone forcibly enables the
raw MMC environment. In this case it would break as of now, as the
current offset of 544KB is far too low for the current (arm64) U-Boot
proper.

selected CONFIG_SPI by default on all Allwinner A64 boards, even though
only 4 out of the 14 A64 boards have a SPI flash chip. All other SoCs
had to manually select DM_SPI and friends, even though they are a
platform property (the sunxi SPI driver is DM_SPI only).
Clean this up to allow easy selection of SPI flash support in U-Boot
proper, by selecting DM_SPI and DM_SPI_FLASH *if* CONFIG_SPI is
selected, for *all* Allwinner SoCs. This simplifies the defconfig for
two Libretech boards already.
Also remove the forced CONFIG_SPI from the A64 Kconfig, instead let the
four boards which allow SPI booting select this explicitly.
Any board wishing to support SPI flash in U-Boot proper now just defines
CONFIG_SPI and CONFIG_SPI_FLASH_<vendor> in its defconfig, Kconfig takes

The stdout-path property in the device tree does not necessarily
point at a serial device. On machines such as the Apple M1 laptops
where the serial port isn't easy to access and users expect to see
console output on the integrated display stdout-path may point at
the device tree node for the framebuffer for example.
If stdout-path does not point at a node for a serial device, the
serial_check_stdout() will not find a bound device and will drop
down into code that attempts to use lists_bind_fdt() to bind a
device anyway. However, that fallback code does not check that
the uclass of the device is UCLASS_SERIAL. So if stdout-path points
at the framebuffer instead of the serial device it will return a
UCLASS_VIDEO device. Since the code that calls this function
expects the returned device to be a UCLASS_SERIAL device, U-Boot
will crash as soon as it attempts to send output to the console.
Add a check here to verify that the uclass of the bound device
really is UCLASS_SERIAL. If it isn't, serial_check_stdout() will
return an error and serial_find_console_or_panic() will use the
serial device with sequence number 0 as the console and all is fine.

The ITS file format (from doc/uImage.FIT/source_file_format.txt)
is not really accurate with the expected naming of these nodes.
But in practice the "conf-" prefix is widely used.
When the FIT image support has been added for ti armv7 platforms
the naming from Arago has been used [3]. Fix this issue by adding
the prefix expected by the ITS file generated by kernel-fitimage
class from openembedded-core.

-d option is currently broken. In most cases BootROM does not detect this
message pattern. For sending debug message pattern it is needed to do same
steps as for boot message pattern.
Implement sending debug message pattern via same separate thread like it is
for boot message pattern.
Checking if BootROM entered into UART debug mode is different than
detecting UART boot mode. When in boot mode, BootROM sends xmodem NAK
bytes. When in debug mode, BootROM activates console echo and reply back
every written byte (extept \r\n which is interpreted as executing command
and \b which is interpreting as removing the last sent byte).
So in kwboot, check that BootROM send back at least 4 debug message
patterns as a echo reply for debug message patterns which kwboot is sending
in the loop.
Then there is another observation, if host writes too many bytes (as
command) then BootROM command line buffer may overflow after trying to
execute such long command. To workaround this overflow, it is enough to
remove bytes from the input line buffer by sending 3 \b bytes for every
sent character. So do it.
With this change, it is possbile to enter into the UART debug mode with
kwboot -d option.

After BootROM successfully detects boot message pattern on UART it waits
until host stop sending data on UART. For example Armada 385 BootROM
requires that host does not send anything on UART at least 24 ms. If host
is still sending something then BootROM waits (possibly infinitely).
BootROM successfully detects boot message pattern if it receives it in
small period of time after power on.
So to ensure that host put BootROM into UART boot mode, host must send
continuous stream of boot message pattern with a small gap (for A385 at
least 24 ms) after series of pattern. But this gap cannot be too often or
too long to ensure that it does not cover whole BootROM time window when it
is detecting for boot message pattern.
Therefore it is needed to do following steps in cycle without any delay:
1. send series of boot message pattern over UART
2. wait until kernel transmit all data
3. sleep small period of time
At the same time, host needs to monitor input queue, data received on the
UART and checking if it contains NAK byte by which BootROM informs that
xmodem transfer is ready.
But it is not possible to wait until kernel transmit all data on UART and
at the same time in the one process to also wait for input data. This is
limitation of POSIX tty API and also by linux kernel that it does not
provide asynchronous function for waiting until all data are transmitted.
There is only synchronous variant tcdrain().
So to correctly implement this handshake on systems with linux kernel, it
is needed to use tcdrain() in separate thread.
Implement sending of boot message pattern in one thread and reading of
reply in the main thread. Use pthread library for threads.
This change makes UART booting on Armada 385 more reliable. It is possible
to start kwboot and power on board after minute and kwboot correctly put
board into UART boot mode.
Old implementation without separate thread has an issue that it read just
one byte from UART input queue and then it send 128 message pattern to the
output queue. If some noise was on UART then kwboot was not able to read
BootROM response as its input queue was just overflowed and kwboot was
sending more data than receiving.
This change basically fixed above issue too.
