Patrick Georgi 51e142fef4 make only needs to read Makefile.incs once, thanks to the
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)

Stefan Reinauer 800379f7aa This patch implements MBI (modular bios interface) support to the i830 chipset.
This is needed on the IP1000T to get VGA output. The VGA option rom will ask
through an SMI for hardware specifics (in form of a VBT, video bios table)
which the SMI handler copies into the VGA option rom.

Patrick Georgi a6c337dec0 Guards against errors that are hard to track down:
- if crt0s is empty (eg. because crt0-y is still used),
  break the build, and say where that behaviour changed
- if a stage is unusable for cbfstool because it's placed
  outside the ROM space (linked to 0 is somewhat notorious),
  warn about it, give some hints and exit instead of crashing.

Patrick Georgi 0da38dde4b Add a "locate" function cbfstool, which helps you find
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.

Also, drop printing of "config.g" input file, we usually only print
generated/output files in the build output.

Finally, rename non-existing COMPRESSFLAG variable to
CBFS_PAYLOAD_COMPRESS_FLAG in a printf line. The build output now says

    PAYLOAD    payload.elf l

for payloads (the "l" specifies LZMA compression).

Stefan Reinauer 3fec29cc96 This separates the code for each command in cbfstool. For the good and for the
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.

Patrick Georgi b203c2f95e 20090819-2-trim-down-cbfs:
CBFS uses sprintf, which requires vtxprintf, which requires (in the
current design) a nested function. That works on x86, but on PPC this

handler - it's only used to fill in fixed-length hex values.

Myles Watson 455e223365 The problem is that the check to see if we're at the end is never reached. I
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
just because it can't find room for a file.

Ronald G. Minnich 6ce41c06cc This is transition code for cbfs to implement
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.

Ronald G. Minnich 56ae8fcb6f This patch implements a "flash friendly" value for initialized areas of flash.
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.
