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).

As of writing, the kernel fork can successfully initialize the SD card and boot postmarketOS off of it. The internal eMMC on the other hand shows these errors:
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.

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).

Mainline

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.
