Subject: [RFC 0/2] Update RAM Bank Logic for RK3588
Date: Sat, 30 Mar 2024 00:05:13 -0500 [thread overview]
Message-ID: <20240330050515.470025-1-macroalpha82@gmail.com> (raw)
From: Chris Morgan <macromorgan@hotmail.com>
Use the ATAG info provided by the Rockchip binary TPL to identify
RAM banks on the RK3588 when using the ROCKCHIP_TPL binary.
This is needed because there are specific addresses that should not
be written to for all RK3588 based devices with >=16GB of RAM, writing
to these addresses immediately results in a crash.
I intended this to be an RFC the first time I submitted it, so I'm
correcting that mistake now. Additionally I have reduced a lot of
the ATAGS code to only focus on the few bits we need in this case.
