Disable CORE 1 and CORE 1 cache to allocate another IRAM segment of 32k

Hello all,

I'm wondering if anyone has ventured into getting another 32k of IRAM when disabling core 1.
I'll be diving into this soon, just figured i would put out some feelers into the community.

It should happen automatically when you disable core 1 in menuconfig.

It doesn't reserve the region so it can be added to iram heap but it isn't available to the linker for iram.
