The mpc85xx EDAC code can be configured as a module but then fails to
build because it uses two unexported symbols:
ERROR: ".pci_find_hose_for_OF_device" [drivers/edac/mpc85xx_edac_mod.ko] undefined!
ERROR: ".early_find_capability" [drivers/edac/mpc85xx_edac_mod.ko] undefined!
We don't want to export those symbols just for this driver, so make
the driver only configurable as a built-in.
This seems to have been broken since at least commit c92132f59806
("edac/85xx: Add PCIe error interrupt edac support") (Nov 2013).

Thanks. It would be nice if you could send it as a fix for 5.2, it's the
last thing blocking one of my allmodconfig builds. But if you don't
think it qualifies as a fix that's fine too, it can wait.
cheers

Sure, no problem. Will do a pull request later.
Thx.

Hmm, so looking at this more, I was able to produce this config with my
ancient cross-compiler:
CONFIG_EDAC_SUPPORT=y
CONFIG_EDAC=m
CONFIG_EDAC_LEGACY_SYSFS=y
CONFIG_EDAC_MPC85XX=y
Now, mpc85xx_edac is built-in and edac_core.ko is a module
(CONFIG_EDAC=m) and that should not work - i.e., builtin code calling
module functions. But my cross-compiler is happily building this without
complaint. Or maybe I'm missing something.
In any case, I *think* the proper fix should be to do:
config EDAC_MPC85XX
bool "Freescale MPC83xx / MPC85xx"
depends on FSL_SOC && EDAC=y
so that you can't even produce the above invalid .config snippet.
Hmmm?

Oh yeah good point.

That's weird.

Yeah that looks better to me. I didn't think about the case where EDAC
core is modular.
Do you want me to send a new patch?
cheers

I've pushed it here:
https://git.kernel.org/pub/scm/linux/kernel/git/bp/bp.git/commit/?h=edac-fix-for-5.2
in case you wanna throw your build tests on it. My dingy cross-compiler
can't do much really.
Thx.
