From: Alex Sierra <alex.sierra@xxxxxxx>
Subject: tools: update test_hmm script to support SP config
Date: Fri, 15 Jul 2022 10:05:19 -0500
Add two more parameters to set spm_addr_dev0 & spm_addr_dev1 addresses.
These two parameters configure the start SP addresses for each device in
test_hmm driver. Consequently, this configures zone device type as
coherent.
