Subject: [PATCH 13/14] spi: airoha: buffer must be 0xff-ed before writing
|
|
|
|
During writing, the entire flash page (including OOB) will be updated
|
|
with the values from the temporary buffer, so we need to fill the
|
|
untouched areas of the buffer with 0xff value to prevent accidental
|
|
data overwriting.
