The ELF parsing and payload building in add-flat-binary command should be
isolated just like mkpayload and mkstage.
Since the add-flat-binary command creates a payload in the end , move payload
processing to cbfs-mkpayload.c.
To test:
cbfstool coreboot.rom add-flat-binary -f u-boot.bin -n fallback/payload \
-l 0x100000 -e 0x100020
To verify, get output from "cbfstool coreboot.rom print -v":
fallback/payload 0x73ccc0 payload 124920
INFO: code (no compression, offset: 0x38, load: 0x1110000, length:..)

Add -v (verbose) to every command, and allow printing debug messages.
Revise logging and debugging functions (fprintf(stderr,...), dprintf...)
and verbose message printing with following macros:
ERROR(xxx): E: xxx
WARN(xxx) W: xxx
LOG(xxx) xxx
INFO(...) INFO: xxx (only when runs with -v )
DEBUG(...) DEBUG: xxx (only when runs with more than one -v)
Example:
cbfstool coreboot.rom print -v
cbfstool coreboot.rom add -f file -n file -t raw -v -v
Normal output (especially for parsing) should use printf, not any of these
macros (see usage() and cbfs_locate(), cbfs_print_directory() for example).

Currently "cbfstool locate" outputs a hex number without "0x" prefix.
This makes extra step (prefix 0x, and then generate another temp file) in build
process, and may be a problem when we want to allow changing its output format
(ex, using decimal). Adding the "0x" in cbfstool itself should be better.

cbfstool.c uses lots of global variables for command line options and all named
as "rom*". This may be confusing when other global variables also start with
rom, ex: int size = rom_size + romsize;
(rom_size is from command line and romsize is the size of last loaded ROM image).
If we pack all rom_* into a struct it may be more clear, ex:
do_something(param.cbfs_name, param.size, &romsize);

This replaces hard-coded bootblock offsets using the new scheme.
The assembler will place the initial branch instruction after BL1,
skip 2 aligned chunks, and place the remaining bootblock code after.
It will also leave an anchor string, currently 0xdeadbeef which
cbfstool will find. Once found, cbfstool will place the master CBFS
header at the next aligned offset.
Here is how it looks:
0x0000 |--------------|
| BL1 |
0x2000 |--------------|
| branch |
0x2000 + align |--------------|
| CBFS header |
0x2000 + align * 2 |--------------|
| bootblock |
|--------------|
TODO: The option for alignment passed into cbfstool has always been
64. Can we set it to 16 instead?

bloated cbfstool and made the code hard to read with a lot
of parsing in the actual cbfs handling functions. This change
switches over to use getopt style options for everything but
command and cbfs file name.
- This allows us to simplify the coreboot Makefiles a bit
- Also, add guards to include files
- Fix some 80+ character lines
- Add more detailed error reporting
- Free memory we're allocating

CBFS allows coreboot rom images that are only partially covered
by the filesystem itself. The intention of this feature was to
allow EC / ME / IMC firmware to be inserted easily at the beginning
of the image. However, this was never implemented in cbfstool.
This patch implements an additional parameter for cbfstool.
If you call cbfstool like this:
cbfstool coreboot.rom create 8192K bootblock.bin 64 0x700000
it will now create an 8M image with CBFS covering the last 1M of
that image.
Test:
cbfstool coreboot.rom create 8192K bootblock.bin 64 0x700000
creates an 8M image that is 7M of 0xff and 1M of CBFS.

Accessing the memory of a char array through a uint32_t pointer breaks
strict-aliasing rules as it dereferences memory with lower alignment
requirements than the type of the pointer requires. It's no problem on
x86 as the architecture is able to handle unaligned memory access but
other architectures are not.
Fix this by doing the test the other way around -- accessing the first
byte of a uint32_t variable though a uint8_t pointer.

SECONDEXPANSION feature of GNU make (and we rely on GNU make for lots of
things already)
File paths are relative to the root directory, which simplifies
debugging (make V=1 gives shorter command lines) and helps ccache
finding matches for checkouts in different directories (even though it
should normalize paths itself)

out a suitable address to put a XIP stage to.
Specifically, you pass it the file (to get its filesize), its filename
(as the header has a variable length that depends on it), and the
granularity requirement it has to fit in (for XIP).
The granularity is MTRR-style: when you request 0x10000, cbfstool looks
for a suitable place in a 64kb-aligned 64kb block.
cbfstool simply prints out a hex value which is the start address of a
suitably located free memory block. That value can then be used with
cbfs add-stage to store the file in the ROM image.
It's a two-step operation (instead of being merged into cbfs add-stage)
because the image must be linked twice: First, with some bogus, but safe
base address (eg. 0) to figure out the target address (based on file
size). Then a second time at the target address.
The work flow is:
- link file
- cbfstool locate
- link file again
- cbfstool add-stage.

bad: It brings a certain amount of code duplication (some of which can be
cleaned up again, or get rid of by proper refactoring).
On the other hand now there's a very simple code flow for each command, rather
than for each operation. ie.
adding a file to a cbfs means:
- open the cbfs
- add the file
- close the cbfs
rather than
open the cbfs:
- do this for add, remove, but not for create
create a new lar
- if we don't have an open one yet
add a file:
- if we didn't bail out before
close the file:
- if we didn't bail out before
The short term benefit is that this fixes a problem where cbfstool was trying
to add a file if you gave a non-existing command because it bailed out on
known, not on unknown commands.

CBFS uses sprintf, which requires vtxprintf, which requires (in the
current design) a nested function. That works on x86, but on PPC this
requires a trampoline. In the ROM stage, this is not available, so
remove the single use of sprintf and replace it with a direct string
handler - it's only used to fill in fixed-length hex values.

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.

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.

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.

I think it is a step in the right direction. Could you add the
function prototype to cbfstool.h?
