-Subject: [PATCH] libahci: Add a pre ahci_start_engine hook
-
-Allwinner A10 and A20 ARM SoCs have an AHCI sata controller which need a
-special register to be poked before starting the DMA engine.
-
-This register gets reset on an ahci_stop_engine call, so there is no other
-place then ahci_start_engine where this poking can be done.
-
-This commit adds a pre ahci_start_engine hook for use by the Allwinner AHCI
-driver (and potentially other drivers in the future).
-
