it would be nice to have this built by default in the

Apologies for the long email ...
Following on from another thread, I have encountered an issue with crc32 within
the mtd system, seemingly only on my AM335x cpu board.
In function ubi_eba_atomic_leb_change() in drivers/mtd/ubi/eba.c, there is a
call
to crc32.
During a remount of my ubifs volume
ve to initialise the gpmc beforehand in some way ?

On one of our products, we have 2 64Mbit NOR devices:- one to hold the
kernel, filesystem, etc, and the other to store "user" data.
The gotcha is that the "user" data is stored using our own wear
levelling code, with read / write / erase operations being carried out
on the raw flash device.

The "exception stack" trace at the end changes depending on when the oops

I've had the oops occur maybe 6 times in the last 50 reboots.

The IDDIG input pin is normally used to determine the USB mode

On some systems (e.g. AM335x) leaving this pin floating allows
