Started actual work on the kernel.  Assumes the cross compiler is at ~/toolchain in the makefile.
Most progress was made by following (and copying code from: http://wiki.osdev.org/ARM_RaspberryPi_Tutorial_C),
which is licensed under CC0 (as is all content on the wiki post-june 6th, 2011).
Added:  a makefile, linker script, code for using the uart as a serial port, a kernel that acts as an echo
over serial (with minicom).
