Subject: [PATCH 2/2] nds32: Fix the dts pointer is not passed correctly issue.
Date: Thu, 28 Jun 2018 18:49:02 +0800 [thread overview]
Message-ID: <20180628104902.9078-1-greentime@andestech.com> (raw)
We found that the original implementation will only use the built-in dtb
pointer instead of the pointer pass from bootloader. This bug is fixed
by this patch.
