Hi Macpaul,

The size of device tree node secmon (bl31_secmon_reserved) was
incorrect. It should be increased to 2MiB (0x200000).

192K should work when the patch(6147314aeedc) was accepted.
Does the trusted-firmware-a get larger now, so we need to
increase the size to 2MiB?

thanks,
Miles

When mt8195-demo.dts sent to the upstream, at that time the size of
BL31 was small. Because supported functions and modules in BL31 are 
basic sets when the board was under early development stage.

Now BL31 includes more firmwares of coprocessors and maturer functions
so the size has grown bigger in real applications. According to the 
value reported by customers, we think reserved 2MiB for BL31 might be 
enough for maybe the following 2 or 3 years.

Thanks for your explanation,
please add this to the commit message and submit next version.

With that, feel free to add:
