[PATCH] mmc: xenon_sdhci: Add missing common host capabilities

[PATCH] mmc: xenon_sdhci: Add missing common host capabilities

[Andre Heider]

Use mmc_of_parse() to set the common host properties. That includes
"bus-width", so parsing it can be removed from the driver.

But more importantly, "non-removable" is now respected, which fixes
the usage of eMMC.

Adding Marek to loop, can you test this patch on MOX A to verify that it
does not break MOX uSD and SDIO support?

(PS: Andre, for one week I would not be available, therefore in this
time I would not be able to test or review Armada 3720 patches...)

I'll also be on vacation next week. Sorry, I was not able to follow all
discussions on these Armada related patches lately. Could someone please
summarize, which patches (fixes) are "okay" for merging in this rc stage
(rc4)? That would really be helpful.

Thanks,
Stefan

Going by patchwork we have:

All superseded:
https://patchwork.ozlabs.org/project/uboot/list/?series=198544
https://patchwork.ozlabs.org/project/uboot/list/?series=198545
https://patchwork.ozlabs.org/project/uboot/list/?series=198756
https://patchwork.ozlabs.org/project/uboot/list/?series=199690

 From my point of view these can go in:

This one, fix emmc:
https://patchwork.ozlabs.org/project/uboot/list/?series=200919
dts: fix vendor, add -emmc variant:
https://patchwork.ozlabs.org/project/uboot/list/?series=199579

These two for uDPU from its maintainer, taken from the OpenWRT 
uboot-mvebu package:
CONFIG_SYS_BOOTM_LEN to 64MB:
https://patchwork.ozlabs.org/project/uboot/list/?series=199858
add support for Macronix mx25u12835f flash:
https://patchwork.ozlabs.org/project/uboot/list/?series=199857

And I'd take these two too, Pali has different opinion though:
enable NET_RANDOM_ETHADDR:
https://patchwork.ozlabs.org/project/uboot/list/?series=200115
set fdtfile:
https://patchwork.ozlabs.org/project/uboot/list/?series=201051

Thanks,
Andre

I shall check this if it does not break our boards.

I have replied to the NET_RANDOM_ETHADDR patch, please comment on my
reply.

As for the fdtfile I think it is good to go.

Thanks. Unfortunately this is taking a bit too long for me, as I
have to leave in about an hour. I will take care of these patches
in a bit over a week.
