332c536425 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.

38e8f8fd88 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.

05ae3d8eeb Use .long on high and low halfs of u64s to avoid .quad 
as it appears .quad isn't available in some assemblers.

f7374f60eb 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.

7a9f663ac7 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.

Pointed out by Mark Greer.
