Basic Timer Interrupt

[chrisdedman]

Description

Configure one hardware timer, and hook its interrupt to increment a "tick" counter.

Note

This implementation is the last implementation of Phase A, the Foundations roadmap of the kernel's development. This phase includes:

Phase A – Foundations

• Bootstrapping: stack setup, BSS clearing, entry into the kernel main. (DONE)
• UART I/O: putc/puts, getc/getline, basic shell loop. (DONE)
• Vector Table: Define vector table for exceptions/interrupts. (Done)
• Basic Timer Interrupt: Configure one hardware timer, hook its interrupt to increment a "tick" counter. (in review)

Additionally, I added a literature directory with the ARM documentation used for this implementation.
