Ward Vandewege ecf4ef0b26 Make sure the address variable is initialized to zero - it is only set when a
[base address] parameter is supplied on the command line... This patch fixes
random segfaults when using 'cbfstool add'.

Ronald G. Minnich 6ce41c06cc This is transition code for cbfs to implement
cbfs files at fixed addresses.

I call this transitional as the approach I am taking is to add
capability to cbfstool but not change code in a way that will break
existing usages. Later, once we're sure nothing has broken, we can start to 
smooth the edges. 

Right now, fixed address file are only supported via the add command. 

There is one additional command syntax, so, example:
cbfstool add rom romstrap optionrom 0xffffd000

Will add the file to that fix location for a romstrap.

The assumption is that the ROM is based at the end of a 32-bit address
space. As you can see from the code, that assumption can easily be
over-ridden, if we ever need to, with a command option.

Here is one example output result.

rminnich@xcpu2:~/src/bios/coreboot-v2/util/cbfstool$ ./cbfstool x.cbf print
x.cbf: 1024 kB, bootblocksize 32768, romsize 1048576, offset 0x0
Alignment: 16 bytes

Name                           Offset     Type         Size
h                              0x0        optionrom   251
                             0x130      free         917120
h3                             0xdffe0    optionrom    251
                             0xe0110    free         97960

The way this is implemented is pretty simple. I introduce a new
operator, split, that splits an unallocated area into two unallocated
areas. Then, allocation merely becomes a matter of 0, 1, or 2 splits:
0 split -- the free area is the exact fit
1 splits -- need to split some off the front or back
2 splits -- need to split off BOTH the front and back

I think you'll be able to see what I've done. I call this transitional
because, in the end state, we only need one allocate function; for now
I've left two in, to make sure I don't break compatibilty.

Why I like this better than ldscript approach: I like having the
ROMSTRAP located by cbfs, not linker scripts. For one thing, it makes
romstrap visible as a first class object. I think I would have latched
onto a problem I was having much more quickly had I remembered the
ROMSTRAP. It gets lost in the linker scripts.

At this point, we should be able to start removing special ROMSTRAP location 
code from linker scripts.
