didn't look into it enough to know why fssize is 32 bytes larger than the
offset. There may be another bug here. Maybe something with the CBFS header
not being included or excluded from the calculation?
Anyway, this patch fixes it for all cases size > 32.
I also changed the error message so that it doesn't look like the ROM is full

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.

This patch moves XIP size back into mainboard code.
Benefits from this patch:
- src/config/nofailovercalculation128.lb is no longer needed
- Targets with XIP sizes besides 64k and 128k benefit from refactoring

instead of coreboot.strip. That fixes the normal
image because the calculations for its offset in
the ROM match reality again.
This requires changes in CBFS configurations to
minimize the bootblock size. These are also done
for CBFS boards.
Other than this a couple of minor fixes are in this
patch:
- make asus/m2v-mx_se build with abuild with a
crosscompiler
- move CONFIG_CBFS for hp/dl145_g3 to Options.lb
as it's done everywhere else
- change the default config of abuild to not
provide ROM_IMAGE_SIZE values for the images
in a CBFS configuration
- change abuild's crosscompile autodetection to
not try to use "i386-elf-i386-elf-gcc" (which
is bogus)
Except for the latter two abuild changes (both
in util/abuild/abuild), they're available as
patch set on the mailing list in a mail from
2009-06-05 titled
[PATCH]es to get normal image to work again with CBFS
The changes in util/abuild/abuild are trivial and
abuild tested.
As discussed on the list,
targets/hp/dl145_g3/Config-abuild.lb is

"
VC is virtual channel. Its used for isochronous transfer of data to sound card.
The virtual channel guarantee "on time" delivery. In other words it sets up a
channel for data to sound card, which means that that arrivs in time and there will
be no interuptions in audio stream.

This reverts commit eb7bb49eb5b48c39baf7a256b7c74e23e3da5660.
Stepan pointed out that "s" means string, which makes the following statement
in this commit message invalid: "Since we either have reserved space (which
we shouldn't do anything with in these two functions), an enum or a
hexadecimal value, unsigned int seemed like the way to go."

This reverts commit c03527377db5951f0d3228e2a93b4c57dd81b8ec.
Stepan pointed out that 's' means string, and that therefor strings do exist.
Marking this as reserved breaks some payloads.

The kontron 986lcd_m cmos.layout had a 512bit area claimed for "boot_devices".
The changes to the cmos code no longer allow usage of values larger than
32bits. Since this option was completely unused, mark it as reserved.
Fixes build after the get_option change (r4332)..

To ease some of my debugging pain on the unichrome, i decided i needed to
move FB size selection into cmos, so i could test a size and then reset it
to the default after loading this value so that the next reboot uses the
(working) default again. This meant implementing set_option in parallel to
get_option.
get_option was then found to have inversed argument ordering (like outb) and
passing char * and then depending on the cmos layout length, which made me
feel quite uncomfortable. Since we either have reserved space (which we
shouldn't do anything with in these two functions), an enum or a
hexadecimal value, unsigned int seemed like the way to go. So all users of
get_option now have their arguments inversed and switched from using ints
to unsigned ints now.
The way get_cmos_value was implemented forced us to not overlap byte and to
have multibyte values be byte aligned. This logic is now adapted to do a
full uint32_t read (when needed) at any offset and any length up to 32, and
the shifting all happens inside an uint32_t as well. set_cmos_value was
implemented similarly. Both routines have been extensively tested in a
quick separate little program as it is not easy to get this stuff right.
build_opt_tbl.c was altered to function correctly within these new
parameters. The enum value retrieval has been changed strol(..., NULL, 10)
to stroul(..., NULL, 0), so that we not only are able to use unsigned ints
now but so that we also interprete hex values correctly. The 32bit limit
gets imposed on all entries not marked reserved, an unused "user_data" field
that appeared in a lot of cmos.layouts has been changed to reserved as well.
