I have a Hynix SLC OneNand spec which says an erase block with an
erase failure or a write error should not be re-written or erased
again but instead just garbage collected and marked bad.
If I switch permanently to the strict erase failure handling, bad
block marking could be too sensitive for some devices expecting
If I switch permanently to the lenient mode, mtdswap would retry
failed erases which would be against chip spec of at least the one
OneNand chip I am working with.
If I remove the config option it would then mean strict handling
