sequentially.

Simplify string table access functions
...
The range sanity checking on the fdt_string_cmp() function causes problems
for the sequential write code (or at least for using RO functions on an
incomplete SW tree). Plus they didn't really fit with the philosphy for
the RO code of working as widely as possible on weirdly constructed trees.

Fix building of dumptrees
...
Without this rather odd constrained pattern rule, make attempts to build

%.o: %.c rules.

dtc: fix endian issue when reading blobs
...
The reserve mem regions are screwy if you read a blob on x86. I'm
guessing there may be a few more of these lurking in the code.

dtc: add setting of physical boot cpu
...
dtc always sets the physical boot CPU to 0xfeedbeef. Add a -b option to
set this. Also add warnings when using the wrong property with the
wrong blob version.

Don't generate the mem-reserve entry for the blob itself,
...
even for ASM output. It was inconsistent with the binary
output form, and kernel folks decided to have the early
kernel perform the reservation itself.

The problem is that asm_emit_cell() was swapping its asm output when
...
it shouldn't be (because the assembler will do the necessary swapping).
The cell values (asm_emit_cell()) are different from the data values
(asm_emit_data()) because the cell values are generated within the
program and don't get swapped like the data values read from the dts file.
They should be left as they are so that the assembler will swap them,
if necessary. For example, when the property length field was 4,
the asm output contained ".long 0x4000000" and sent the kernel prom.c
dt parsing code into the weeds.
