[commit] r6335 - in trunk: payloads/external/SeaBIOS src/arch/x86

[repository service]

Author: stuge

New Revision: 6335
URL: https://tracker.coreboot.org/trac/coreboot/changeset/6335

Log:
Reliably build arbitrary Kconfig-based revisions of SeaBIOS

Reliability is accomplished by checking out the desired SeaBIOS commitish
into a branch named 'coreboot' in the local SeaBIOS git repository. Using
a branch allows TAG-$(CONFIG_SEABIOS_..) to refer to any commitish in the
SeaBIOS git repo, not just branches and tags.

Configuration is done with make defconfig followed by enabling and
disabling of the relevant coreboot-specific SeaBIOS options by appending
to .config using echo. This works, because later entries in .config will
overwrite earlier ones.
