Subject: [PATCH] mtd: spinand: esmt: add support for F50L1G41LC
|
|
|
|
This adds support for ESMT F50L1G41LC, which appears to be an updated
|
|
version of the already supported F50L1G41LB.
|
|
Add esmt_8c SPI_NAND manufacturer to account for the newly used vendor
|
|
ID with support for the ESMT F50L1G41LC chip.
