[PATCH v3 1/9] MIPS: generic: Allow generating FIT image for Marduk board

From: Jiaxun Yang
Date: Tue Jul 20 2021 - 23:02:48 EST


Marduk is based on IMG pistachio SoC. The platform is using
MIPS UHI booting protocol and does have a proper devicetree
implement, thus it could be a part of generic kernel.
