[v3] Improve the MT8365 SoC and EVK board support

[PATCH v3 03/17] arm64: dts: mediatek: Increase the size BL31 reserved memory

Posted by amergnat@baylibre.com 1 year, 5 months ago

From: Alexandre Bailon <abailon@baylibre.com>

The reserved size for BL31 is too small.
This has been highlighted by the MPU that now restrict access to BL31
memory to secure world only.
This increase the size of the reserved memory.
