> It is an open-source boot firmware(BSD-2-Clause-Patent license) and one of UEFI BIOS alternatives like coreboot and bare-metal u-boot. Slim Bootloader is leveraging EDK2 frameworks/tools/libraries and following its coding standard. That's why it looks like a lite EDK2 BIOS in appearance, but it's much closer to coreboot.
> Slim Bootloader covers from reset vector to OS hand-off with multi-stage approach(Stage1A/B -> Stage2 -> Payload -> OS) and it consumes Intel FSP 2.x image on each stages for silicon initialization including cache-as-ram and memory initialization. Stage1/2 are doing silicon specific initialization thru FSP and platform specific configuration while Payload is responsible for OS load/hand-off. So, rich/universal payload like u-boot is also a key part of Slim Bootloader.
> For payload options, Slim Bootloader currently supports OsLoader which is Slim Bootloader's default payload for Linux booting and EDK2 UEFI payload for Windows booting. We'd also like to enable u-boot as a universal payload. Thanks.

Any plan to have it as a gplv2 code?
