Some patches are required to fix some emmc unreliability seen on AMD platforms.
These were ported over from the EOS kernel and applied properly.

@Staphylo can you rebase this onto the current master branch so that we can get this merged onto the master branch, and cherry-picked for 202211?

I just rebased my changes on top of master.

As a side note, if my change to drivers/mmc/host/sdhci-pci-core.c is seen as too dangerous, I could leverage the append_quirk* change to encode all the necessary quirks via the cmdline for the affected product only.

sdhci.append_quirk=0x20 sdhci.append_quirk2=0x240

It would amount to enabling:

  • SDHCI_QUIRK_BROKEN_ADMA
  • SDHCI_QUIRK2_BROKEN_64_BIT_DMA
  • SDHCI_QUIRK2_BROKEN_HS200

Are there plans to upstream, at minimum, patch/driver-arista-mmcblk-not-working-on-AMD-platforms.patch?

There is currently no plan to upstream this.
As mentioned in my previous comment, if that's a problem for you I could do everything via kernel parameters and drop driver-arista-mmcblk-not-working-on-AMD-platforms.patch

@yxieca this fix is already on 202205.
The only diff is in the patch description since I added a few lines here.
I don't think there's anything to do for 202205.
