Mainline
According to Documentation/arm/marvell.rst
the PXA1908 chipset should be supported, but it is unknown whether it's actually supported.
Downstream
It's possible to compile the Samsung-provided downstream kernel with some config changes (arch/arm64/configs/pxa1908_coreprimevelte_eur_defconfig
should be used as a defconfig):
CONFIG_CRYPTO_XTS
should be set, and CONFIG_ANDROID_PARANOID_NETWORK
should be unset. These are required by postmarketOS.
CONFIG_OPTIMIZE_FOR_SIZE
should be set, or the boot image will be too big for the partition.
The concatenated dtb blob should be generated with https://github.com/osm0sis/pxa-mkbootimg, because the G361F's chipset is a bit different.
Booting
The SM-G361F uses the Marvell PXA1908 chipset, which uses a nonstandard boot.img and dtb format, handled by pxa-mkbootimg.
Additionally, the device requires a legacy U-Boot kernel image as the kernel in boot.img, with a quirk: the image name must be exactly pxa1928dkb linux
. With this parameter overridden, the device boots successfully into the postmarketOS kernel, and USB networking is available, however it automatically reboots after around 3-4 minutes of uptime. This is yet to be investigated.
