5.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dikshita Agarwal <dikshita@xxxxxxxxxxxxxx>
[ Upstream commit 255385ca433ce5ff621732f26a759211a27c8f85 ]
This patch adds a 6xx specific boot logic. The goal is to share as much
code as possible between 3xx, 4xx and 6xx silicon.
We need to do a different write to WRAPPER_INTR_MASK with an additional
write to CPU_CS_H2XSOFTINTEN_V6 and CPU_CS_X2RPMh_V6.
The other writes are the same for 6xx and non-6xx silicon albeit at
different absolute relative locations to the base of the venus address
space.
