Description Paul Whalen 2014-05-13 14:05:36 UTC 
Description of problem:
ARM block device modules need to be explicitly added to the initramfs but should be found automatically. Currently we need to either add the 'sunxi-mmc' module to support All-Winner devices or fix block device module detection for ARM.

patch to add mmc/sdhci drivers to generic initfs to enable boot from SD cards

This patch uses a more generic means of detecting which drivers are needed for MMC/SD booting on devices that have SD cards that aren't attached by USB like most ARM devices and tablets

fixes a typo on the last patch

ahci/mmc/sdhci patch that was sent upstream

This was the final patch the I've sent upstream too (vger seems to be slow so I don't have an link yet)

Currently the block driver detection for generic initrd doesn't include
the SD/MMC drivers so we fail to boot generic images on any device using
those platforms as boot devices when using a generic initrd. Add logic
to detect those modules. This primarily fixes embedded ARM devices but
also likely intel tablets/dev boards and enterprise hypervisors that
have the ability to boot from SD.

Also the ahci_init_controller misses a number of drivers that use the
libahci_platform module for the init so this fixes some missing achi
moduless too.

Finally it cleans up the ARM storage module hacks that the above now
deals with in a more generic manner.
Comment 4 Peter Robinson 2014-06-30 17:45:17 UTC 
This was fixed in dracut 38 upstream, now in rawhide
