* 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.
* 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.
* Enable/Disable makes more sense and matches
platform loader serial functions.
* Rework PL011 code after finding a PDF covering
the details of it.
* Rename UART global defines in loader to be more
exact about location
* This makes things a little more flexible and
the interface to use the uarts cleaner.
* May want to make a generic Uart wrapper
class in uart.h / uart.cpp and call drivers
as needed from there.
* Avoid name collisions
* This uart stuff may work better as a class at
some point, however I didn't want to rock the
u-boot boat *too* much as I don't have the
hardware to test.
* Add nested function wrappers to allow usage of other
uart drivers depending on board. We may want to use this
on other platforms at some point (haha, maybe)
* Make Kernel ARM UART slightly more generic
through (BOARD_UART_CLOCK) configured per board
* Add initial Raspberry Pi serial code
* Still rough and non-working
* Change ShowTip() point parameter name to where.
* Add a parameterless ResetWindowFrame() overload that get's the current
where and calls ResetWindowFrame(BPoint where) which does the actual
work. FrameResized() calls this parameterless ResetWindowFrame()
method instead of doing the work in that method. This is functionaly
the same but allows me to call the parameterless ResetWindowFrame()
elsewhere.
SharedSolver was archiving too many constraints, partly because of
multiple typos, also because it archived some which were just artifacts
of the layout process. These extra constraints are created when the
layout calls SetRange() on the left/top/right/bottom tabs during layout.
* LinearSpec/ActiveSetSolver had to be adjusted to get access to the
constraints added by the SetRange() calls.
* BALM::TabBase was adjusted to avoid a segfault during unarchiving,
caused by an unitialized member.
* ALMFriendLayoutTest was adjusted to include a more obvious custom
constraint for testing.
Also make ALMGroup totally self-contained, i.e. BALMLayout no longer
does the parsing, and is completely unaware of ALMGroup. A small touch
of refactoring as well.
