Patrick Georgi f16fb73087 I thought that romfs infrastructure is done now, but there were some
issues (see buildbot).
The romfs image was always built, and sometimes broke (because of
the different image layouts) for buildrom images. After the patch, these
issues are avoided by not adding payloads to the romfs image (they
wouldn't be read anyway). Both workarounds (in buildrom code for
romfs and vice-versa) aren't very pretty, but that's what our buildsystem
requires.
As I had to create a "communication channel" (via the romfs-support
files), I took the chance to also use it for compression
information, so if you configure lzma support, you'll get lzma
compressed payloads in romfs.

Patrick Georgi aed1f925a6 the attached patch is the last infrastructure change necessary for
romfs.
Everything else to make a target romfs aware happens in the targets.

What the patch does:
1. missing romfs.h include
2. special handling while creating coreboot.rom
While the romfs code path in the makefile doesn't actually use the file,
it's possible that the build of coreboot.rom fails in a romfs setup,
because the individual buildrom image is too small to host both coreboot
and payloads (as the payloads aren't supposed to be there). Thus, a
special case to replace the payload with /dev/null in case of a romfs
build.
There would be cleaner ways, but they're not easily encoded in the
Config.lb format.
3. config.g is changed to create rules for a romfs build

Targets should still build (they do for me)

I've attached a patch that removes the 3-mile-long compiler
commandlines, which vim's quickfix doesn't like so much. Instead of
putting all those -DXYZ='bla' on the compiler commandline, they are put
in a file called settings.h (as #define XYZ bla) and only a
--include=settings.h is put on the commandline.
This file is created unconditionally at the same time as when the
CPUFLAGS simply expanded make variable used to be created (not via a
target rule and dependency), so it shouldn't change anything.

Stefan Reinauer 38bee3c8b6 This patch fixes the ugly race condition created through build_opt_tbl
running twice at the same time, overwriting its output files. This caused
a depending rule to produce an object file with no symbols in it.

This should silence up the regularly happening build failure messages on
the mailing list since we moved to the newer, much faster server.

Carl-Daniel Hailfinger 00809ebf02 This changes the python generated makefiles
targets/*/*/Makefile
        targets/*/*/normal/Makefile
        targets/*/*/fallback/Makefile

to use a common copy of romcc, and to leave this compiler untouched by
'make clean' in targets/*/*/fallback/ and targets/*/*/normal/ .
'make clean' in targets/*/*/ will clean romcc.

Thanks to Mats for the initial idea and implementation of a tool to do
this. This patch has almost the same behaviour as the original tool
without having to run the tool each time.
Tested for abuild-friendliness.

The patch saves ~10-12 seconds for every target using romcc. For a full
abuild run, this is ~20% time saved.
For the first 38 abuild targets, total build time is down to 13m24s
instead of 16m22s on my machine.

Richard Smith 273595c6f7 - fix dependency rule for Makefile and Makefile.settings
The make dependency rule for Makefile and Makefile.settings was completely broken.  No way it ever worked.
OLPC buildrom flushed out this issue.

If you updated the Config.lb file in your target/<mfg>/<mainboard> directory and then switched to 
target/<mfg>/<mainboard>/<target> and ran 'make' you would get a permission denied error due to the 
make file trying to run 'config.py' directly rather than 'python config.py'
We never saw this because we always run target/buildtarget <target> and that sets up everything
correctly.

Greg Watson 4f8311ae58 These changes tighten up rules for exporting options.
1. Exportable options ('export used') used to be exported if referred to in
   a 'uses' statement. These options will now only be exported if the
   option is set, or the default value is changed.

2. Options marked as 'export always' with no default value ('default none')
   used to generate defines with no values 'export k8:='. This behavior
   has changed so that the option will ONLY be exported if it has a value
   assigned using 'set' or 'default'. Otherwise it is an error.

Eric Biederman 5cd81730ec - Moved hlt() to it's own header.
- Reworked pnp superio device support.  Now complete superio support is less than 100 lines.
- Added support for hard coding resource assignments in Config.lb
- Minor bug fixes to romcc
- Initial support for catching the x86 processor BIST error codes.  I've only seen
  this trigger once in production during a very suspcious reset but...
- added raminit_test to test the code paths in raminit.c for the Opteron
- Removed the IORESOURCE_SET bit and added IORESOURCE_ASSIGNED and IORESOURCE_STORED
  so we can tell what we have really done.
- Added generic AGP/IOMMU setting code to x86
- Added an implementation of memmove and removed reserved identifiers from memcpy
- Added minimal support for booting on pre b3 stepping K8 cores
- Moved the checksum on amd8111 boards because our default location was on top of
  extended RTC registers
- On the Hdama added support for enabling i2c hub so we can get at the temperature
  sensors.  Not that i2c bus was implemented well enough to make that useful.
- Redid the Opteron port so we should only need one reset and most of memory initialization
  is done in cpu_fixup.  This is much, much faster.
- Attempted to make the VGA IO region assigment work.  The code seems to work now...
- Redid the error handling in amdk8/raminit.c to distinguish between a bad value
  and a smbus error, and moved memory clearing out to cpufixup.
- Removed CONFIG_KEYBOARD as it was useless.  See pc87360/superio.c for how to
  setup a legacy keyboard properly.
- Reworked the register values for standard hardware, moving the defintions from
  chip.h into the headers of the initialization routines.  This is much saner
  and is actually implemented.
- Made the hdama port an under clockers BIOS.  I debuged so many interesting problems.
- On amd8111_lpc added setup of architectural/legacy hardware
- Enabled PCI error reporting as much as possible.
- Enhanded build_opt_tbl to generate a header of the cmos option locations so
  that romcc compiled code can query the cmos options.
- In romcc gracefully handle function names that degenerate into function pointers
- Bumped the version to 1.1.6 as we are getting closer to 2.0

  TODO finish optimizing the HT links of non dual boards
  TODO make all Opteron board work again
  TODO convert all superio devices to use the new helpers
  TODO convert the via/epia to freebios2 conventions
  TODO cpu fixup/setup by cpu type

Greg Watson 8cb747942c New option behavior:
1. Options can only be set with 'option' statement in the target
   configuration file. Options can be set as many times as needed.
2  Option DEFAULT values can be changed (or set) in any configuration file.
   Changing a default value will display a warning message.
3. A default value is changed with the statement 'default <op> = <val>'.
4. Setting an option overrides the default value.
5. The 'mainboard' and 'arch' statements now set options implicitly. No
   'uses' statement is required.

The idea is that parts will define default values for options that
they need/use. Option overrides are only done in the target file.
