It makes the write part of flashrom dramatically faster with small
payloads like filo; and it also eliminates unnecessary wear on flash
by not writing zeros (it's unlikely this really matters; let me know
next time you flash a BIOS flash 100,000 times!).
More importantly, it allows for future partial flash upgrades with cbfs.
Note that uninitialized_flash_value is a global that can, if we ever need it,
be set by an argument in main. Assuming we ever see a flash where the
"erased" value is 0, not 0xff.
At the same time, "erased" value has been "1" on every EEPROM or
FLASH I've used for some time now.

critical, since unless it is fixed this tool creates empty tables that cause
coreboot to (in some cases, e.g. on qemu) triple fault and die.
For the record, an empty option_table is not allowed. The table must,
at least, have 3 32-bit entries in this order:
type -- should be 200, 0r 0xc8, i.e. 0xc8, 0, 0, 0
size of table in LE order, 4 bytes
size of header in LE order, which is always 12,0,0,0

src/lib/ code in coreboot. I.e. the tool changes but the coreboot code
does not.
Currently, as cbfstool manages the ROM, there are files and empty
space. To allocate files, the code does, first, a walk of the headers
and, if that fails, does a brute-force search of the rest of the
space.
We all agree that the brute-force search has lots of problems from a
performance and correctness standpoint.
I've made a slight change. Instead of an "empty space" area with no
valid headers, I've made a header for the empty space.
So cbfs creation looks like this:
- set up the boot block
- create a file, of type CBFS_COMPONENT_NULL, that contains the empty
space. CBFS_COMPONENT_NULL was already defined in cbfs.h
Here's an example:
[rminnich@xcpu2 cbfstool]$ ./cbfstool testcbfs create 1048576 2048
(cbfstool) E: Unable to open (null): Bad address
[rminnich@xcpu2 cbfstool]$ ./cbfstool testcbfs print
testcbfs: 1024 kB, bootblocksize 2048, romsize 1048576, offset 0x0
Alignment: 16 bytes
Name Offset Type Size
0x0 0xffffffff 1046456
So how do we create a new file?
It's easy: walk the files and find a file of type CBFS_COMPONENT_NULL,
which is as large
or larger than the file you are trying to create. Then you use that file.
- if the file is the same size as the NULL file, then it's easy: take it
- if the file is smaller than the NULL file, you split the NULL file
into two parts.
note that this works in the base case: the base case is that the whole
storage is CBFS_COMPONENT_NULL.
Here's an example of adding a file.
[rminnich@xcpu2 cbfstool]$ ./cbfstool testcbfs add-stage testfixed t
[rminnich@xcpu2 cbfstool]$ ./cbfstool testcbfs print
testcbfs: 1024 kB, bootblocksize 2048, romsize 1048576, offset 0x0
Alignment: 16 bytes
Name Offset Type Size
t 0x0 stage 23176
0x5ab0 0xffffffff 1023240
Note that the NULL split and got smaller. But the entire ROM is still
contained by the two files. To walk this entire rom will require two
FLASH accesses.
Add another file:
[rminnich@xcpu2 cbfstool]$ ./cbfstool testcbfs add-stage testfixed tt
[rminnich@xcpu2 cbfstool]$ ./cbfstool testcbfs print
testcbfs: 1024 kB, bootblocksize 2048, romsize 1048576, offset 0x0
Alignment: 16 bytes
Name Offset Type Size
t 0x0 stage 23176
tt 0x5ab0 stage 23176
0xb560 0xffffffff 1000024
[rminnich@xcpu2 cbfstool]$
So, taking current ROMs as an example, I can reduce FLASH accesses for
cbfs from (potentially) thousands to (typically) less than 10.
Index: fs.c
Changes for readability and cleanliness. Move common blobs of code to functions.
New function: rom_alloc,which allocates files by finding NULL files and using/splitting.
Other changes as needed to support this usage.
Index: util.c
Creating a cbfs archive now requires creation of a NULL file covering the file system space.
Index: cbfs.h
Add a DELETED file type with value 0. Any file can be marked deleted by zero its type; this is a
FLASH-friendly definition for all known FLASH types.

/dev/null for one compile test.
The old variant of using &>/dev/null works on bash and zsh, but not on
dash and tcsh. dash and tcsh interpret it as "background command and
truncate /dev/null" which is not what we want. >& works on tcsh and
bash, but it is not POSIX compliant.
Since make uses /bin/sh and /bin/sh has to be POSIX compliant, we can
use the POSIX variant of stderr and stdout redirection.
>/dev/null 2>&1
is POSIX compliant. This is specified in SuSv3, Shell Command Language,
sections 2.7.2 and 2.7.6.

probe/read/erase/write. That is incorrect.
A bit of confusion comes from how the #defines are named. We call them
TEST_BAD_*, but the message printed by flashrom says:
"This flash part has status NOT WORKING for operations:"
Something that is unimplemented is definitely not working.
Neither of the chip entries mentioned above has erase or write functions
implemented, so erase and write are not working.
Since their size is unknown, we can't read them in. That means read is
not working as well.
Probing is a different matter. If a chip-specific probe function had
matched, we wouldn't have to handle the chip with the "unknown xy SPI
chip" fallback. I'm tempted to call that "not working" as well, but I'm
open to discussion on this point.
