Subject: [PATCH 116/203] mtd: nand: pxa3xx: Allow to set/clear the 'spare
|
|
enable' field
|
|
|
|
Some commands (such as the ONFI parameter page read) need to
|
|
clear the 'spare enable' bit. This commit allows to set/clear
|
|
depending on the prepared command, instead of having it always
|
|
set.
