91102c544e Logging calculations was done outside the #def TRACE_VM_PAGE, but never printed. 
Now done inside #def as well as this triggered unused variables warnings.

548b1a4988 cpuid: Rework AMD CPUID numbers 
* If family is 0xF, we grab extended family and model
  like Intel does
* Idenfify AMD cpu's more correctly

dc09611aad U-Boot: move gFDT declaration to shell.S 
* this avoids it falling into the BSS section which we clear quite late,
and allows setting it from asm code if needed.

cce9d8cf89 U-Boot PPC: Enable ppc440 FPU correctly 
* On ppc440, the FPU is implemented as an Auxiliary Processing Unit,
we must therefore enable sending commands to it,
in addition to setting the MSR bit.

b7aa0a94ff ARM platform: Undo change to MMU page table assignment 
* While the baremetal arm book I have says mrc, it breaks
  verdex and doesn't work on the Pi.
* Moving the page table address to the p15 coprocessor makes
  more logical sense anyway... i think mrc was a typo.

1348022133 PPC: Move asm helpers to U-Boot arch Jamfile 
* the OpenFirmware arch/ppc/Jamfile already has it, so move it to avoid duplicated symbols.

037f252fd0 U-Boot: split cpu.cpp into arch-specific and common parts 
* the common part should try to use the U-Boot API when found.
* the arch part can make use of cpu features (like timer register)
* the ppc code enables the FPU in the MSR, since it's used by vsnprintf(),
which at least saves one FP register in its prologue.

361ec26f10 rPi MMU: Cleanup, add gPeripheralBase 
* gPeripheralBase keeps track of the device
  peripherals before and after mmu_init
* Add ability to disable mmu for troubleshooting
* Remove static FB_BASE, we actually don't know
  where the FB is yet. (depends on firmware used)

021ccbd18f Fix #8596: common_getgroups copies too little data 
common_getgroups, when called from within the kernel, copies actualCount
bytes instead of actualCount * sizeof(gid_t) bytes.

9c5e60f656 rPi MMU: Fixes to hrev44189 
* I had the wrong addresses, 0x20 was the physical
  address not a mapped one.
* Attempt to map uart in mmu post mmu_init.

b8733e36c7 rPi MMU: Working towards mapped memory 
* BCM2708 defines no longer assume 0x20 address
  We will be throwing away the blob memory mapping
  and using our own.
* Use existing blob mapping to turn GPIO led on pre mmu_init
* Remap MMU hardware addresses from 0x7E. We could map each device,
  however the kernel will throw away the mappings again anyway. For
  now we just map the whole range and use offsets.
* Serial uart no longer works, however at least
  we know why now :). Serial driver now needs to
  use mapped address.

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.

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.

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.
