This patch syncs up TPM2 sources into the build area when building
cr50 image. This relies on a specific directory layout so that the ec
makefile has access to the tpm2 source tree.
The sources are copied using rsync, the tpm2 library is a dependency
for the RO/RW elf images, and is declared to be a phony make target,
which guarantees that the tpm2 make is always run when cr50 image is
built.
Include files in board/cr50/tpm2 are necessary to be able to build
tpm2 code using the bare metal toolchain used for building ec code.
memory.h is in fact empty, it is easier to add it here than to wrap it
in conditional compilation at the source.
Make variables CROSS_COMPILE and CFLAGS are exported for the benefit
of the tpm2 makefile. ROOTDIR indicates where tpm2 library should look
for .h files not available from the toolchain.
CQ-DEPEND=CL:292946
BRANCH=none
BUG=chrome-os-partner:43025
TEST=make buildall -j succeeds;
when linked with the latest tpm2 source, the combined image
starts the tmp task and reacts to the host sending the startup
command (failing due to unplugged stubs).
