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.

4ffe10ca33 rpi gpio: Remove alt0 mode on serial pins
* Confirmed this places pins in miniUART mode
  (we don't want this mode however)
* We do need to fully understand *which* mode
  the pins need to be in for PL011 mode.. however
  the boot state of the Pi is PL011

   previous revisions.
