This is not where to look for whether or not bridging is built into the
kernel. There is a configuration system of building a config file
in the top level of the source tree. This file is usually there
as
.config
hence you do not normally see it unless you use the -a option to ls.
However TS provide starting config files that initialise this .config
with default values - go and read the TS kernel building documentation.
Apart from this bit (and the fact its crosscompile), the kernel build
operation is pretty much as anyother linux build would be on any other
platform.
