[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v2 39/62] tools/firmware: Build and install xen-shim
From: Andrew Cooper <andrew.cooper3@xxxxxxxxxx>
Link a minimum set of files to build the shim. The linkfarm rune can
handle creation and deletion of files. Introduce build-shim and
install-shim targets in xen/Makefile.
We can do better by properly generate the dependency from the list of
files but that's an improvement for later.

v2: Introduce a top-level build-shim target. Split the xen-shim build
with normal build.
