Subject: arm64: dts: mediatek: Increase the size BL31 reserved memory
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2d98d0d2d53720a365e0c1a2984215815337607c;p=linux.git
arm64: dts: mediatek: Increase the size BL31 reserved memory
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.
