it is identical to fam15h_rdimm, with _udimm now removed;
the latter had a patch that added certain behaviour only
intended for rdimm, but the patch in question breaks various
configurations.

raminit has always been unreliable on these boards. i'd rather
simplify it all, in lbmk. i'll probably update this to the dasharo
tree later on, specificalyl for kgpe-d16

this is using the same functionality that was added a few
commits ago, to override the use of "git submodule update"

each coreboot submodule has two repositories defined, with
the second one kicking in if the mail one fails upon cloning.

firstly, memtest86+ is currently not cross compiled and
relies on 64-bit headers (x86_64 only). a 32-bit distro
is unlikely to be able to build 64-bit binaries.

secondly: vboot throws a build error due to -Werror when
building on 32-bit hosts. we rely on vboot code to build
cbfstool, so turn off -Werror on vboot

that's all. 32-bit hosts are not recommended; it is assumed
that you are building on an x86_64 host. work will go into
the build system at a later date to make it more portable,
by cross compiling everything, but this should fix 32-bit
for now.

there are some x60/t60 users who still want to build roms,
so let's allow them that possibility.
