Subject: [PATCH] [PATCH] of_reserved_mem: Increase the number of reserved regions
Date: Sun, 4 Oct 2020 13:50:24 +0800	[thread overview]
Message-ID: <20201004055024.23542-1-phil.chang@mediatek.com> (raw)

Certain SoCs need to support large amount of reserved memory
regions, especially to follow the GKI rules from Google.
In MTK new SoC requires more than 68 regions of reserved memory
for each IP's usage, such as load firmware to specific sapce,
so that need to reserve more regisions
