Hai all,
I'm trying to port the u-boot to the 2019.04-aspeed-openbmc,
Here trying to apply *.patch file and also applying the defconfig for the
u-boot from the specific meta-layer.

In this case, the defconfig file changes have been applied clearly to
u-boot in tmp, but those patch files are copying to the machine tmp folder
but not applied to the code!

Is there any restriction for applying patches to the 2019.04-aspeed openbmc
?
If not, is there any other suggestion for applying patches.
