Simon,

All 32-bit Tegra builds of u-boot-dm/master are failing with the
following (this log is from Harmony):

Oh wow, that is a strange one. Could it be bad Python cache files again?

Ah yes, so it is. I'd forgotten about that, and initially thought it
couldn't be the issue, since the problem only affects some boards not
all, and on my system they're all built in the same source tree
(serially). However, I guess our 64-bit builds don't run the tool that
triggers the problem, so that explains the differences.

Deleting tools/binman/etype/__init__.pyc did solve the issue, and that
file doesn't get re-created if 16287933a8 "binman: Move to absolute
imports" is applied.

Do you know what causes the issue, or how it can be avoided?

Maybe running "git clean -fdx" on the source tree before building would
be a workaround, but I'd rather solve the root-cause if possible.

Actually I don't know. But the file you mention looks like something
that Python 2 would create. So perhaps it is not allowed to run Python
2 on a project, then remove a file, then run Python 3. Since the file
is removed (but not the .pyc), perhaps Python 3 gets confused? This
seems like a bug though, since Python 3 really should not be looking
at pyc files created by Python 2.
