[PATCH] ARM: dts: nuvoton: Fix flash layout

[Tomer Maimon]

Hi Benjamin and Anton,

Sorry for the late reply,

The EVB FIU0-CS0 partitioning is used for testing the EVB and this is why
it is different than the OpenBMC flash layout.



Are you using the NPCM7XX EVB for OpenBMC? if yes we can consider to modify
the flash partition to OpenBMC use.
