[PATCH]: Add raspberrypi as OpenBMC platform

[Yi Li]

Hi,

I created an initial patch to Add raspberrypi as OpenBMC platform for review.
I can build obmc images, but I don't have a raspberrypi HW to boot and test.
So this patch does not include the full meta-raspberrypi layer.
There is a README included for testing.

Please have a look and if this patch can be tested on HW I will submit a formal patch.

Thanks,
-Yi

+1. Under openbmc directory, checkout meta-raspberrrypi layer:
+# git://git.yoctoproject.org/meta-raspberrypi
+
+2. Apply meta-raspberrypi_obmc.patch
+# cd meta-raspberrypi/conf
+# patch < meta-raspberrypi_obmc.patch
+
+3. Build obmc:
+# rm -fr build/conf
+# export TEMPLATECONF=meta-raspberrypi/conf
+#  . oe-init-build-env
+# bitbake obmc-phosphor-image
+
+4. Remaining issues:
+a. No raspberrypi HW, so image not tested
+b. u-boot-fw-utils build failed. Removed the package.
