* Small bit of style cleanup as well
* Better comment function usage

77591e9657 rPi: MMU Work 
* Use U-Boot mmu code as base
* This will be factored out someday into common arch mmu
  code when we can read Flattened Device Trees
* Move mmu_init after serial_init.
  Temporary change as we will want serial_init to use
  memory mapped addresses... for debugging.

8b99a08215 rPi: Fix Raspberry Pi binaries 
* Since mmu_man fixed these vars to actually be used,
  we now know these floating point flags cause issues
  on the Raspberry Pi currently.

55cf6de91b Fix passing flags from BoardSetup 
* 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.

François Revol
e9ec7a55dd Attempt to factor out serial stuff 
* introduce a DebugUART baseclass,
* rework 8250 and PL011 implementations from kallisti5 to inherit DebutUART,
* each arch should override the IO methods to access registers.
* on ARM registers are 32bit-aligned.
* U-Boot still works for the verdex target.
* rPi still compiles, needs testing.
* Still some more consolidation needed to allow runtime choice of the UART type (as read from FDT blobs for ex.).
* serial.cpp should probably mostly be made generic as well.
* didn't touch x86 or ppc yet.

08a1406831 rpi: Remove firmware blobs 
* 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

91161d1d6f pl011 uart: Fix fifo states 
* Lets wait for space *before* writing to the fifo
  instead of after.
* Flush functions now really flush the fifo waiting
  for them to enter an empty state.
* Simple memory barriers added (may need revised)
  We don't have access to the kernel barriers here.

ec3c24ab07 pl011 uart: Work around Rpi constructors not getting called 
* Serial UART output on Raspberry Pi now functioning
  This is kind of a hack, however having serial output
  will enable easier debugging of loader. Not a perimant fix.
* With UART output, we can now turn to why the constructors
  are so messed up.
* Thanks to pfoetchen for his help and (lots!) of testing.
