What would happen if you realize mid-way that you cannot erase some
sector , do you end up w

This is a transitional patch: non-uniform erase maps will be used later
when initialized based on the SFDP data.
What about non-SFDP non-linear flashes ?

This patch is a first step in introducing the support of SPI memories
with non-uniform erase sizes like Spansion s25fs512s.
It introduces the memory erase map which splits the memory array into one
or many erase regions. Each erase region supports up to 4 erase commands,
