Subject: [PATCH] mtd: spi-nor: support limiting 4K sectors support based on
|
|
flash size
|
|
|
|
Some devices need 4K sectors to be able to deal with small flash chips.
|
|
For instance, w25x05 is 64 KiB in size, and without 4K sectors, the
|
|
entire chip is just one erase block.
|
|
On bigger flash chip sizes, using 4K sectors can significantly slow down
|
|
many operations, including using a writable filesystem. There are several
|
|
platforms where it makes sense to use a single kernel on both kinds of
|
|
devices.
|
|
|
|
To support this properly, allow configuring an upper flash chip size
|
|
limit for 4K sectors support.
