We probably don't want to reduce the sizes of the heaps that were larger than 512KB. You should probably look through the last patch for those files and pull in the changes to their Kconfigs that were removed.

Looking at the state of things before the patch this is replacing, you probably want to add the line:

```
default 0x100000 if FLATTENED_DEVICE_TREE
```
