c3a9b90973 Access the device tree blob via copyin/copyout. 
The code previously assumed that copyin/copyout did no
address translation and that the device tree blob could
be manipulated in-place (with only a few adjustments for
the ELF loader offset).  This isn't possible on all platforms,
so the revised code uses copyout() to copy the device tree
blob into a heap-allocated buffer and then updates the
device tree with copyout().  This isn't ideal, since it
bloats the loader memory usage, but seems the only feasible
approach (short of rewriting all of the fdt manipulation
routines).

50ddc3c4f7 Ooops. Back out changes to main.c from r235094. 
This change is specific to BeagleBone; I need to figure out how to
generalize this before committing.

5bf877dace Don't call strcmp with a NULL pointer. 
In particular, on the AM335x, which comes up with no memory
mapped to low addresses, dereferencing the NULL causes a crash.

04296b6f18 Improve device tree blob (DTB) handling in loader(8). 
Enable using the statically embedded blob from the kernel, if present. The KLD
loaded DTB takes precedence, but they are both recognized and handled in the
same way.

6031d0b167 Get rid of bootinfo for good in loader (U-Boot-based) and ARM. 
For FDT-enabled platforms the device tree is a modern replacement for bootinfo
config data.

04cb90189b Initial loader(8) support for Flattened Device Tree. 
o This is disabled by default for now, and can be enabled using WITH_FDT at
  build time.

o Tested with ARM and PowerPC.

This will [soon] be needed for ARM.

63094c199a MFp4 (e500): 
Add support for U-Boot. This uses the U-Boot API as developed by
Rafal and which is (will be) part of U-Boot 1.3.2 and later.
