Increase size of the coreboot table area
Packing a device tree into the coreboot table can easily make the table exceed the current limit of 8KB. However, right now there is no error handling in place to catch that case. Increase the maximum memory usable for all tables from 64KB to 128KB and increase the maximum coreboot table size from 8KB to 32KB.
