[PATCH v2 0/3] ARM: boards: add support for Samsung Galaxy S8 and S20 5G

[Ivaylo Ivanov]

Hey folks,

This patchset focuses on adding support for S8 and S20. It's designed to
allow adding support for new exynos devices easy, with the primary
differentiating factor being the device tree. Currently, the same built
barebox-exynos.img can be booted on both S20 and S8 without any changes
in the code, as it can dynamically recognize what device it's booting on
based on the tree provided at x0 from the previous bootloader (s-boot).

On these devices, barebox will be used as a shim after the stock bootloader
(s-boot), replacing the linux kernel image in the boot.img.

Please read the patch commit messages, I've tried to describe everything
well enough. Thanks!

Best regards,
Ivaylo
