This remedies an issue with the MBL Duo if both disks are inserted and contain OpenWrt. kernel and dtb would be loaded from SATA 1:1 while rootfs (/dev/sda2) would be mounted on SATA 0:1. Such a mix&match would obviously only work if both OpenWrt versions/ builds are identical, and especially fail after sysupgrade upgraded the system disk on SATA 0:1. The fallback to SATA 1:1 needs to be kept for MBL Single (only has SATA 1:1) and MBL Duo with one disk inserted on SATA 1:1. To speed up booting in those cases, the unneccesarily doubled "sata init" will only be called once. (In theory it could be omitted completely since the on-flash boot script already initializes SATA to load the on-disk boot script.) Tested on MBL Duo (all possible combination of disks) and MBL Single Signed-off-by: Freddy Leitner <hello@square.wf> Acked-by: Christian Lamparter <chunkeey@gmail.com>
