+Subject: [PATCH] kernel-modules: Fix storage module selection for
+ sdhci/mmc/ahci
+
+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.
