[DistroKit] [PATCH 0/5] enable uploading kernel, dtb and initramfs over fastboot and boot it on Rock3A

[Johannes Zink <j.zink@pengutronix.de>]

This series enables building Android sparse images of kernel, dtb and
initramfs for the Radxa Rock3A, enables mounting corresponding ram-files
as fastboot partitions in the barebox fastboot gadget, and adds support
for booting the image uploaded via fastboot.

This can be useful in situations, where booting a Linux system is
required on such target without touching the nonvolatile storage, e.g.
for debugging purposes.

For uploading kernel, dtb and initramfs use

fastboot flash kernel    platform-v8a/images/kernel-sparse.img
fastboot flash dtb       platform-v8a/images/dtb-rock3a-sparse.img
fastboot flash initramfs platform-v8a/images/initramfs-sparse.img

then for booting either use the barebox command

boot fastboot

or pass the bootcommand over fastboot from the host via

fastboot oem exec boot fastboot

Johannes
