An archive (ramfs) to be loaded can be specified in the raspberry pi
config.txt with a certain base address. We can use this to put our
floppy boot archive into memory on startup.
During the start procedure we now map that archive so we can later
load the kernel from it.
* since we include BoardSetup earlier now, the TARGET_* flags were discarded. Use HAIKU_* instead.
* Add variables to hold the default entry point and the desired uimage OS emulation.
* Pi firmware was updated to note that Broadcom
had to be included with firmware blobs.
* While we have permission from Eben to have the
blobs in-tree, they are now offically on github
in a fixed location removing the need to have
these in-tree.
* Clean up BoardConfig, note firmware URL and
files needed
* Update info.txt with how Haiku boot process works
