Fix E6400 display reference clock patches

The ones I submitted before seem to have been outdated ones
that don't actually build properly.

Fix E6400 display issue with 1440 x 900 panel

2024-05-20T16:46:25+00:00

The E6400 uses a 100 MHz reference clock on DPLL_REF_SSCLK, whereas
libgfxinit assumed that the reference was always 96 MHz. The frequency
difference caused by a 100 MHz reference with PLL config values
calculated assuming a 96 MHz reference were not significant enough to
cause noticable issues with the more common 1280 x 800 panels, but are
enough to matter for the 1440 x 900 panels which use a higher pixel
clock. This only affected the pre-OS graphics environment provided by
libgfxinit, as Linux drivers would determine the reference clock
frequency based on data in the VBT.

Fix this by making the reference clock frequency in libgfxinit
configurable for GM45 based on a new coreboot Kconfig, which is set to
100 MHz for the E6400.

update coreboot/dell to same rev as default

2024-01-25T16:09:19+00:00

re-use the same patches, and drop the same patches.

this tree uses hell's special ddr2 fix, which we apply
for the dell latitude e6400.

git.sh: support downloading dependency trees

2024-01-21T12:59:02+00:00

a tree can specify:

tree_depend="treename"

this will make the other tree be downloaded. this is
used for coreboot trees, to ensure that dependency
trees are downloaded, because trees can now re-use
crossgcc from other trees.

re-use crossgcc builds on the coreboot trees

2024-01-21T06:26:23+00:00

don't build crossgcc twice, especially if two coreboot
trees use the same revision!

update/trees: further simplify crossgcc handling

2023-12-27T16:07:32+00:00

arch no longer needs to be set, on multi-tree projects,
and it has been renamed to xarch

the new behaviour is: if xarch is set, treat it as a
list of crossgcc targets and go through the list. set
the first one as the target, for what lbmk builds, but
build all of the defined crossgccc targets

crossgcc_ada is now xlang, and defines which languages
to build, rather than whether to build gcc-gnat

build/roms: remove modify_coreboot_rom()

2023-12-21T19:26:22+00:00

don't handle "romtype" at all, in board target.cfg files

add /dev/null as pike2008 rom on amd boards. this serves
the same purpose, adding them as empty vga roms, to add
an empty rom in cbfs. pike2008 cards cause seabios to hang,
when their oproms are executed, so we insert a fake rom

on i945 thinkpads, use the coreboot config option:
CONFIG_INTEL_ADD_TOP_SWAP_BOOTBLOCK

when set, this enables the same bootblock copy, for use
with bucts. these two cases, namely pike2008 roms and
i945 bootblock copies, no longer need to be handled in code

update/trees: simplified crossgcc handling

2023-12-21T14:18:51+00:00

only call crossgcc for coreboot and u-boot, but use
hostcc for everything else. simplify the checking of
which architecture to compile for. "arch" in target.cfg
files has been modified, to allow further simplification.

without this patch, the logic currently only *barely* avoids
using crossgcc on things like utils, and only works in practise
because, in practise, lbmk only works on x86_64 anyway.

the new logic, as per this patch, is simpler and more robust.
