wtf is bootstack?

L4T Bootstack is a collection of low-level startup files for getting Linux or Android running on the Nintendo Switch. It provides the bootloaders and early-startup scripts that tell the device how to power on and load an operating system. In simple terms, when a computer or device turns on, it needs instructions telling it how to find and start the operating system. This project provides those instructions, known as "bootloaders," specifically for the Switch. It includes things like an "initramfs" (a tiny temporary filesystem loaded into memory before the main OS starts) and u-boot scripts (instructions that point the device to where the OS lives). These files work together to let the device boot into either Linux or Android from its internal storage. This project would be used by hobbyists or developers who want to run a full Linux distribution or Android on the Nintendo Switch hardware. For example, someone who wants to turn their Switch into a portable Linux machine for retro gaming or web browsing would rely on these boot files to make that possible. The automated build process uses Docker, which is essentially a self-contained environment that packages all the necessary tools together, so users can generate their own boot files without manually installing dozens of individual programs on their computer. The project supports different configurations, letting users build boot scripts specifically for either GNU/Linux or Android. It also includes hardware-specific "overlays" for the Tegra210 chip inside the Switch, which help the operating system communicate with the device's internal storage (eMMC) or debug ports.
