OK that made some progress. It still looks like some command processor is
running at the same time as the login process.
It printed "U-Boot SPL 2017.05-dirty (Aug 23 2017 - 15:20:51)
drivers/ddr/alt" on the serial console and then went quiet. Next thing I
saw was that it had apparently loaded the kernel and was waiting for a user
name.
However, some process was feeding characters that were being consumed by
the login process. Every so often it would hit something that corresponded
to something the command processor recognized and display a bunch of stuff
on the screen again, like a help menu. Look at the file I captured and see
if it helps understand what is going on. I don't know what process is
putting up the various help menus.
Thanks,
Alan

<bus> - Identifies the SPI bus
<cs> - Identifies the chip select
<mode> - Identifies the SPI mode to use

env ask name [message] [size] - ask for environment variable
env default [-f] -a - [forcibly] reset default environment
env default [-f] var [...] - [forcibly] reset variable(s) to their default
values
env delete [-f] var [...] - [forcibly] delete variable(s)

env print [-a | name ...] - print environment
env run var [...] - run commands in an environment variable
env save - save environment
env set [-f] name [arg ...]
=> exit - exit script
exit - exit script
fatload - load binary file from a dos filesystem
Usage:
fatload <interface> [<dev[:part]> [<addr> [<filename> [bytes [pos]]]]]
- Load binary file 'filename' from 'dev' on 'interface'
to address 'addr' from dos filesystem.
'pos' gives the file position to start loading from.
If 'pos' is omitted, 0 is used. 'pos' requires 'bytes'.
'bytes' gives the size to load. If 'bytes' is 0 or omitted,
the load stops on end of file.
If either 'pos' or 'bytes' are not aligned to
ARCH_DMA_MINALIGN then a misaligned buffer warning will
be printed and performance will suffer for the load.
