This serial converts x86 boards to use MMC for driver model. It has to
disable SCSI to make this work, for now. Once SCSI is sorted out, we can
apply the patch.

This is not to be applied. It is needed to test using CONFIG_DM_MMC on x86
since SCSI is broken with this setup.

Convert the pci_mmc driver over to driver model and migrate all x86 boards
that use it.

I tracked down the exception happens at part_test_efi()->block_dread() function:
if (!ops->read)
return -ENOSYS;
Where ops points to nowhere, because underlying SATA device does not
have a DM driver associated.
Could you please fix this?

I've been hoping that someone else will take on this side of things,
but perhaps I am optimistic. I'll see if I can take a look.

I've sent a series which I think puts SCSI and SATA in a better
position with respect to driver model. However even with that there is
more work to do.

Thanks for working on this! I will take a look.
If we don't get enough time to sort out everything, we will have to
revert previous MMC DM conversion patch and leave that to next
release.

Yes, let's see how it goes. I probably have time for one more spin if
it is soon...but the last patch needs work.

As Andreas has pointed out here:
https://lists.denx.de/pipermail/u-boot/2017-June/296337.html
SCSI seems to be broken also on Armada 37xx (and perhaps other
platforms as well). Is it correct to assume, that this x86 SCSI
thread is about the same issue?
I know that you are working on DM SCSI support, which is great of
course. But do you have an idea, if and how this could be fixed for
this upcoming release?
Thanks,
Stefan

Simon already sent a series to convert SCSI to DM and applied to
u-boot-dm. I also sent a series to fix some additional issues [1].
Can you or Andreas try on top of u-boot-dm plus my patches to see if
the issue is fixed?

I tested with this version and "scsi reset" still reboots the
board. Please note that SCSI / AHCI probably needs some additional
work, as its currently supported via this driver in arch/arm
which needs to moved to the correct driver directory:
arch/arm/mach-mvebu/sata.c
It probably also needs some work to function correctly with these
new DM SCSI patches. But all this seems a bit late in this release
cycle. Do we have a "solution" to fix this issue for this upcoming
release?
Thanks,
Stefan

Did the failure happen at the place part_test_efi()->block_dread() function?
if (!ops->read)
return -ENOSYS;
Where ops points to nowhere ..
If so, I think the SATA driver needs to be converted to DM.
But I don't know if a simple solution exists for now on your board. I
noticed that Andreas said v2017.01 works but v2017.03 is failing. So
it has been broken for some time. But Simon's series aims to resolve
the issues seen on x86, which is an intermediate issue in this release
cycle.

Bin

I sent a pull request (forgetting to cc the list) for this but it was
too close to RC2 so Tom rejected it. It is sitting in dm/master if you
want to look.
At this stage I don't have a good answer. Even my series doesn't
complete the SATA conversion to DM. We still need AHCI to have proper
operations and convert the rest of the drivers. I was hoping that
might be easier once the powerpc removals are complete.

Simon

Since the pull request of u-boot-dm was rejected for this release, I
sent a revert patch for x86 [1] to fix x86 SCSI issues.
Is Armada 37xx converted to use DM MMC? If so, maybe a quick fix is to
revert the Armada 37xx board back to use non-DM MMC, like x86 does?

Thanks for the explanation.

Understood. Might be that we can only solve this in the next
release cycle then.

The SDHCI driver for Armada 37xx (and 7k/8k) was added only recently
and directly as a DM driver. So I can't move it back to non-DM
without bigger effort - which does not make much sense.
My feeling is, that its probably best to do the SCSI / AHCI DM
conversion soon in the next release cycle and I will definitely
help with converting / testing on the Armada 64bit platforms then.
Thanks,
Stefan
