In theory maybe but in practice it for sure won't show up if the vendor
has its own SATA solution and at least in the ARM world it seems frequent
to have its own AHCI variant nowadays.  Moreover even if the new usage
shows up it is not enough to enable driver for it to make it work as
you also need to add a node describing your SATA MV variant to your SoC
device tree file (which requires updating kernel source anyway).
