Subject: [PATCH 2/2] mtd: spi-nor: disable 16-bit-sr for macronix
|
||
|
|
|
||
|
|
Macronix flash chips seem to consist of only one status register.
|
||
|
|
These chips will not work with the "16-bit Write Status (01h) Command".
|
||
|
|
Disable SNOR_F_HAS_16BIT_SR for all Macronix chips.
|
||
|
|
|
||
|
|
Tested with MX25L6405D.
|
||
|
|
|
||
|
|
Fixes: 39d1e3340c73 ("mtd: spi-nor: Fix clearing of QE bit on
|
||
|
|
lock()/unlock()")
