Subject: [PATCH] mtd: rawnand: brcmnand: Support write protection setting from
|
|
dts
|
|
|
|
The write protection feature is controlled by the module parameter wp_on
|
|
with default set to enabled. But not all the board use this feature
|
|
especially in BCMBCA broadband board. And module parameter is not
|
|
sufficient as different board can have different option. Add a device
|
|
tree property and allow this feature to be configured through the board
|
|
dts on per board basis.
