[U-Boot] [PATCH 0/2] mmc: Fix partition table init regression

[Andre Przywara]

Commit d0851c893706 ("blk: Call part_init() in the post_probe() method")
in the 2019.01-rc1 merge window moved the partition init call to the
generic DM layer, leaving every non-DM driver behind. As the result all
Allwinner boards now don't read the partition table automatically
anymore:
=> fatls mmc 0
** Unrecognized filesystem type **
=> fatload mmc 0 $kernel_addr_r Image-4.20-rc3
** Unrecognized filesystem type **

A quick workaround is to explicitly read the partition table, but this is
still a regression, as it breaks existing scripts and workflows:
==========
=> mmc part

Partition Map for MMC device 0  --   Partition Type: DOS

Part    Start Sector    Num Sectors     UUID            Type
  1     8192            30873600        00000000-01     0c
=> fatls mmc 0
   852304   xen
 23544320   Image-4.20-rc3

2 file(s), 0 dir(s)
==========

These two patches are the minimal version to fix this problem, by bringing
the implicit part_init() call back just for non-DM MMC drivers.
Patch 1 is needed to keep the H6 SPL below the size limit.

The whole SPL_LIBDISK_SUPPORT symbol is now somewhat obsolete and needs
some proper fixing, but this needs more discussion and testing and
is probably nothing for this release still.

Thanks,
Andre.

[U-Boot] [PATCH 1/2] sunxi: drop default SPL_LIBDISK_SUPPORT enablement

[Andre Przywara]

There is no code for using partition labels in the Allwinner SPL port.
Even so the name is slightly misleading, CONFIG_SPL_LIBDISK_SUPPORT was
meant to guard partition code for the SPL.

Remove the "imply" line in the Kconfig to make this obvious and avoid
unneeded code inclusions, helping to keep the H6 SPL code small.

[U-Boot] [PATCH 2/2] mmc: bring back partition init for non-DM MMC drivers

[Andre Przywara]

Commit d0851c893706 ("blk: Call part_init() in the post_probe() method")
removed the call to part_init() in mmc.c, as this is done by the DM_MMC
framework.
However Allwinner is (still) relying on a non-DM MMC driver, so we are
now missing the implicit partition init, leading to failing MMC accesses
due to the missing partition information.

Bring the call back just for non-DM MMC driver to fix this regression.

So, this pushes pine_h64 over the limit:

It seems you are missing patch 1/2?
https://lists.denx.de/pipermail/u-boot/2018-December/352283.html
(sunxi: drop default SPL_LIBDISK_SUPPORT enablement)

I put this one in for exactly this reason.

I have some other cleanups which reduce the H6 SPL size by 2K, will send
them out shortly.

Cheers,
Andre.

Thanks, I don't know why I thought that was in already.
