[coreboot] Source code download difficulties

[Ken.Fuchs at bench.com]

I'm able to easily download the coreboot kernel from
qa.coreboot.org, but all ancillary source code like FILO
and libpayload are not easy to download.  I'm behind
firewall/proxy that allows only http and maybe https
(with _valid_ certificates).  In addition, the
coreboot.org SSL certificate doesn't seem to be
validated by a recognized certificate authority.

$ svn co https://coreboot.org/svn/trunk/coreboot-v2
svn: PROPFIND request failed on '/svn/trunk/filo'
svn: PROPFIND of '/svn/trunk/filo': 405 Method Not Allowed
(https://coreboot.org)

There seems to be a way to use tracker to get zip files of
source code, but it doesn't seem to be available for all
coreboot projects.  What is the recommended way to get
coreboot ancillary project source code like FILO and
libpayload when svn and https/WebDAV protocols are not
available or don't work?

All coreboot source code should be available via one or
more tarballs (like the coreboot kernel itself).

Sincerely,

Ken Fuchs
