Marvell PXA1908 is a low-end ARM64 SoC, released in either late 2014 or 2015 according to various online sources.
There is a modemless variant of this SoC called IAP140 (see https://lore.kernel.org/lkml/8737f7yyc8.fsf@belgarion.home/T/#m92f43e1a24549a1421cbe19dfe74cf0db8c550c6).

A work-in-progress tree is available here.
S-Boot can pass the initramfs to the kernel only when the default kernel cmdline is used. Also, S-Boot does not start the ARM architected timer as it should, requiring a hack in the kernel which probably can't be upstreamed into Linux (at least not inside the clock driver).
eMMC runs in HS200 mode with a hack whose unfortunate consequence is "Tuning failed" errors being spammed in dmesg.
WiFi is rather flaky: sometimes firmware uploading fails, sometimes it stops working very shortly after firmware upload and sometimes it stops working after a few hours of normal use.
