At present SCSI support for driver model works only with PCI controllers.
This series makes the following changes:
- Adjusts SATA/AHCI support to work with non-PCI controllers
- Allows driver model to be used for MMC in U-Boot proper without
requiring it to be used in SPL
- Adjusts sunxi MMC and SATA drivers to support driver model
- Enables this on a single board (Linksprite_pcDuino3)
Even with this series the AHCI uclass still does not have any operations.
This will be needed for drivers which do not use SCSI. Further work is
needed to complete this.
Changes in v2:
- Drop debugging printf() now that the card detect is working
- Add new patch to correct polarity of MMC card detect on Linksprite_pcDuino3

At present the AHCI SCSI driver only supports PCI with driver model.
Rename the existing function to indicate this and add support for adding
a non-PCI controller .

At present if U-Boot proper uses driver model for MMC, then SPL has to
also. While this is desirable, it places a significant barrier to moving
to driver model in some cases. For example, with a space-constrained SPL
it may be necessary to enable CONFIG_SPL_OF_PLATDATA which involves
adjusting some drivers.
Add new SPL versions of the options for DM_MMC, DM_MMC_OPS and BLK. By
default these follow their non-SPL versions, but this can be changed by
boards which need it.

This function appears to obtain the value of the 'ranges' property rather
than 'reg'. As such it does not behave as documented or expected.
In addition it picks up the second field of the property which is the size
(with prop += naddr) rather than the first which is the address.
Fix it.

When the SATA code was moved into drivers/ata these Kconfig options were
added to that directory. They already exist in drivers/scsi. Remove them
from drivers/ata to fix the duplication.

This is expected to be attached to the uclass and the code operates that
way, but the uclass has not been updated. Fix it to avoid using memory at
address 0.

Use the driver-model naming convention for this structure. It is data
private to the driver so the local variable should be called 'priv'.

At present the driver-private data is obtained in various functions by
various means. With driver model this is provided automatically. Without
driver model it comes from a C array declared at the top of the file.
Adjust internal functions so that they are passed the private data as
a parameter, allowing the caller to obtain it using either means.

This function has #ifdefs in it which we want to avoid for driver model.
Instead we should use different compatible strings and the .data field.
It also uses the MMC device number which is not available in driver
model except through aliases.
Move the function's into its caller so that the driver-model version can
do things its own way.

Add a driver-model version of this driver which mostly uses the existing
code. The old code can be removed once all boards are switched over.

The 'scsi scan' function handles this at present and we don't want to
do it twice. With driver model we want to adopt U-Boot's lazy init
approach where possible.
Drop the automatic scan when probing a SCSI bus.

This is not used in SPL so we do not need to compile it. Make this change
before adding driver-model support to the driver, to avoid build errors.
With driver model we define a U_BOOT_DRIVER() which would otherwise be
present in SPL and not be garbage-collected when building.

Move this board over to driver model for MMC and SATA. This means that it
uses CONFIG_BLK as well. In SPL these options remain turned off since it
increases the code size. One option would be to use CONFIG_SPL_OF_PLATDATA
to avoid device-tree overhead.

Hmmm, are you sure? At least your commit log says otherwise :)

There are numerous places where #if(n)defCONFIG_BLK is used, should they
not all be replaced with #if CONFIG_IS_ENABLED(BLK) ? In my case
common/env_mmc.c won't compile because of this.
Other than this problem with common/env_mmc.c and a few other
adjustments not related to the mmc that unselecting DM_SPL required,
this has been tested OK on a TI DRA72 evm.

I don't see a build error, but I'll rebase to master and see if I can.
My approach was to change the common uses and ones I had to change,
but not going an change all boards to do this. I suspect it is the
right thing to do ultimately, but for many boards it doesn't matter.

The commit message is wrong, unfortunately. The schematics suggest it
is active low and it does seem to work with this setting.

eMMC is currently broken for sunxi on my Orangepi Plus 2E.
I've narrowed it down to this patch.
It seems the driver or device is now referencing the wrong
controller. On versions before this patch, for MMC1 (or eMMC):
=> mmc dev 1
switch to partitions #0, OK
mmc1(part 0) is current device
=> mmc info
Device: SUNXI SD/MMC
Manufacturer ID: 15
OEM: 100
Name: AWPD3
Tran Speed: 52000000
Rd Block Len: 512
MMC version 5.0
High Capacity: Yes
Capacity: 14.6 GiB
Bus Width: 8-bit
Erase Group Size: 512 KiB
HC WP Group Size: 8 MiB
User Capacity: 14.6 GiB WRREL
Boot Capacity: 4 MiB ENH
RPMB Capacity: 4 MiB ENH
On later versions I get:
=> mmc dev 1
switch to partitions #0, OK
mmc1 is current device
=> mmc info
Device: SUNXI SD/MMC
Manufacturer ID: 27
OEM: 5048
Name: SD08G
Tran Speed: 50000000
Rd Block Len: 512
SD version 3.0
High Capacity: Yes
Capacity: 7.4 GiB
Bus Width: 1-bit
Erase Group Size: 512 Bytes
For reference, mmc0 looks like:
=> mmc dev 0
switch to partitions #0, OK
mmc0 is current device
=> mmc info
Device: SUNXI SD/MMC

So it seems somewhere down the line, the driver is getting

Are you sure it was this patch?
The ordering may have changed because there was a strange hack in the
code before. There was some discussion about it but unfortunately I
cannot find the thread right now. Can you take a look?

So I was playing around with this for the Pine64 based on your
pcDuino3 example patch and it doesn't find the MMC controller, is
there other DM conversions that might be needed for some of the sunxi
devices?

Indeed it was this patch. Maxime's latest patch [1] fixes it.
And looks like the hacks are on their way out as well.

Unfortunately card detect is not working on the BananaPi:
I built Bananapi_defconfig which defaults to not using the driver model
and U-Boot is able to read from the SD card:
MMC:
SUNXI SD/MMC: 0
Loading Environment from FAT... *** Warning - bad CRC, using default
environment
I added
CONFIG_BLK=y
CONFIG_DM_MMC=y
And the same SD card is not recognized anymore.
MMC:
mmc at 01c0f000: 0
Loading Environment from FAT... MMC: no card present
mmc_init: -123, time 2
At least for clock registers there seem to be differences:
mmc_resource_init: priv->mclkreg = 01c20094 (without DM_MMC)
sunxi_mmc_probe: priv->mclkreg = 01c20088 (with DM_MMC)
Best regards

Most likely it's the problem of U-Boot interpreting the card detection
DT properties differently from Linux. See this thread for details:

Thanks for your analysis
arch/arm/dts/sun7i-a20-bananapi.dts
has 'cd-inverted' for MMC0.
The string 'cd-inverted' does not exist in drivers/mmc/sunxi_mmc.c.
sunxi_mmc_getcd():
return dm_gpio_get_value(&priv->cd_gpio);
sunxi_mmc_getcd_legacy():
return !gpio_get_value(cd_pin); /* Observe the NOT here */
I will keep you informed.
Regards
Heinrich
