Bootloader, Device-Tree, and Early-Kernel Labs

Construct a boot-artifact and address map that follows an ARM system from Boot ROM through TPL or SPL, U-Boot Proper, the kernel, the root filesystem, and PID 1.

Analyze U-Boot startup code to locate temporary stack setup, board_init_f, DDR initialization, relocation, and board_init_r.

Configure a U-Boot environment and boot command that load a kernel, DTB, and initramfs from a specified storage device without overlapping their memory regions.

Read and modify device-tree nodes using compatible, reg, interrupts, clocks, phandles, aliases, chosen, and pinctrl properties.

Compile, decompile, and validate a DTB while resolving one schema, address-cell, or phandle error.

Explain the ARM64 U-Boot-to-kernel register handoff and trace execution through head.S, MMU activation, and start_kernel.

Trace Linux early memory initialization from memblock handover to buddy-system setup and SLUB initialization.

Trace driver-model population, kernel-thread creation through rest_init, and VFS root-filesystem mounting up to PID 1 execution.
