Existing format options were unclear on how much spiffs you were
getting. Also add missing 1MB App/3MB Spiffs split.
This addresses #1799

This makes it very clear what each option gives you, and also adds 2 options
to get ffat on 4MB chips..

Hi @me-no-dev @CelliesProjects you just committed 4930853 which caused a conflict with this PR which offers more and better descriptions.
I just resolved it, but can you please consider this change this does more than what you just merged?

Thanks @me-no-dev . I sent you a small tweak to extend the space allocation to the default partitions too (including the ffat one you just added)

Hello,
I'm doing tests with the new ffat partitions and I noticed an error on the default_ffat.csv partition.
This new partition causes a permanent reset.
I did not have this problem with the previous partition that contained an EEPROM partition.
It works when I replace the line:
ffat, data, fat, 0x291000,0x170000,
by :
ffat, data, fat, 0x290000,0x170000,
