[PATCH openEuler-5.10 14/29] habanalabs/gaudi: fix LBW RR configuration

15 Nov 2021

From: Oded Gabbay ogabbay@kernel.org
stable inclusion
from stable-5.10.72
commit 6a4aaf1d84f75fc86961d5982f2b43d1897de1d3
bugzilla: 182982 https://gitee.com/openeuler/kernel/issues/I4I3L1
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit 0a5ff77bf0a94468d541735f919a633f167787e9 ]
Couple of fixes to the LBW RR configuration:
1. Add missing configuration of the SM RR registers in the DMA_IF.
2. Remove HBW range that doesn't belong.
3. Add entire gap + DBG area, from end of TPC7 to end of entire
   DBG space.
