Usage: 

include path

path can be relative to the current directory or absolute starting at /src.

I tested it with:

include /config/absolute.lb
include relative.lb

in /src/northbridge/amd/amdk8/Config.lb

Myles Watson a80a61049b This patch allows you to add lines of the form
pci_rom PATH vendor_id = # device_id = #

to Config.lb files.  No more changing the ROM_SIZE to add an option ROM, and no more manual prepending.

Examples:

pci_rom ../ragexl.rom vendor_id = 0x1002 device_id = 0x4752
pci_rom ../nic.rom vendor_id = 0x1100 device_id = 0x4152

Stefan Reinauer 14ad50edf6 This fixes a race condition (revealed by my other check-in r4067) in the
romtool by changing the Makefiles to be no longer recursive (once again,
recursive make is to be considered harmful).  Tried to (quickly) unify most of
the Makefile code, but medium-term this is going to be worked on for Kconfig
support anyways.

Also fix a sign cast error in rom-mkpayload in case people want to compile this
with -W -Werror

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.

2009-04-03 14:04:06 +00:00
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

putting all those -DXYZ='bla' on the compiler commandline, they are put

This file is created unconditionally at the same time as when the
CPUFLAGS simply expanded make variable used to be created (not via a

Stefan Reinauer 764fe40f09 This patch adds "high coreboot table support" to coreboot version 2.
Some bootloaders seem to overwrite memory starting at 0x600, thus destroying
the coreboot table integrity, rendering the table useless.

By moving the table to the high tables area (if it's activated), this problem
is fixed.

In order to move the table, a 40 bytes mini coreboot table with a single sub
table is placed at 0x500/0x530 that points to the real coreboot table. This is
comparable to the ACPI RSDT or the MP floating table.

This patch also adds "table forward" support to flashrom and nvramtool.

Patrick Georgi d229677b61 20090310-3-scanbuild:
Add support for clang's scan-build utility to abuild. scan-build wraps
the compiler and runs its own compiler on the same sources to do some
static analysis on them. It adds an option "-sb" or "--scan-build" that
creates a coreboot-builds/$target-scanbuild directory for every $target,
containing the output of scan-build, which is a HTML documentation on
its results.
Be aware, that scanbuild significantly increases build time: A board
that takes 6-7 seconds normally requires 60 seconds with that option
enabled on my test system.
The patch also moves the stack-protector option down a bit, so it
applies to crosscompiled targets, too (which overwrote the compiler
settings before)

Carl-Daniel Hailfinger 3b1a955cce FreeBSD definitions of (read|write)[bwl] collide with our own. Before we
attempt trickery, we can simply rename the accessor functions.

Patch created with the help of Coccinelle.

Carl-Daniel Hailfinger 59c36f97db During the conversion of flash chip accesses to helper functions, I
spotted assignments to volatile variables which were neither placed
inside the mmapped ROM area nor were they counters.
Due to the use of accessor functions, volatile usage can be reduced
significantly because the accessor functions take care of actually
performing the reads/writes correctly.

The following semantic patch spotted them (linebreak in python string
for readability reasons, please remove before usage):
@r exists@
expression b;
typedef uint8_t;
volatile uint8_t a;
position p1;
@@
 a@p1 = readb(b);

@script:python@
p1 << r.p1;
a << r.a;
b << r.b;
@@
print "* file: %s line %s has assignment to unnecessarily volatile
variable: %s = readb(%s);" % (p1[0].file, p1[0].line, a, b)

Result was:

The following semantic patch uses the spatch builtin match printing
functionality by prepending a "*" to the line with the pattern:

It's arguably a bit easier to read if you get used to the leading "-"
for matching lines.

Carl-Daniel Hailfinger ac12ecd27a flashrom: Use helper functions to access flash chips.
Right now we perform direct pointer manipulation without any abstraction
to read from and write to memory mapped flash chips. That makes it
impossible to drive any flasher which does not mmap the whole chip.

Using helper functions readb() and writeb() allows a driver for external
flash programmers like Paraflasher to replace readb and writeb with
calls to its own chip access routines.

This patch has the additional advantage of removing lots of unnecessary
casts to volatile uint8_t * and now-superfluous parentheses which caused
poor readability.

I used the semantic patcher Coccinelle to create this patch. The
semantic patch follows:
@@
expression a;
typedef uint8_t;
volatile uint8_t *b;
@@
- *(b) = (a);
+ writeb(a, b);
@@
volatile uint8_t *b;
@@
- *(b)
+ readb(b)
@@
type T;
T b;
@@
(
 readb
|
 writeb
)
 (...,
- (T)
- (b)
+ b
 )

In contrast to a sed script, the semantic patch performs type checking
before converting anything.

Stefan Reinauer 21c8b5ab5c With this patch the v2 build system will create a directory hierarchy
similar to what v3 does. This is required to have two source files with
the same name but in different directories. (As in, two different SuperIOs on
board, with a superio.c each)
