277	  When using multi-CPU chips it is possible for U-Boot to start up
278	  more than one CPU. The stack memory used by all of these CPUs is
279	  pre-allocated so at present U-Boot wants to know the maximum
280	  number of CPUs that may be present. Set this to at least as high

324	  is generated by U-Boot in the system memory from 0xf0000 to 0xfffff
325	  at every 16-byte boundary with a PCI IRQ routing signature ("$PIR").

332	  The Simple Firmware Interface (SFI) provides a lightweight method
333	  for platform firmware to pass information to the operating system
334	  via static tables in memory.  Kernel SFI support is required to
335	  boot on SFI-only platforms.  If you have ACPI tables then these are
336	  used instead.

404	  This is the memory-mapped address of PCI configuration space, which

406	  Mechanism (ECAM) with PCI Express. It can be set up almost
407	  anywhere. Before it is set up, it is possible to access PCI
408	  configuration space through I/O access, but memory access is more
409	  convenient. Using this, PCI can be scanned and configured. This
410	  should be set to a region that does not conflict with memory
