1 Subject: mtd: spi-nor: add mx25l25635f with SECT_4K
2
3 This patch fixes an issue with the creation of the
4 ubi volume on the AVM FRITZ!Box 4040. The mx25l25635f
5 and mx25l25635e support SECT_4K which will set the
6 erase size to 4K. This is used by ubi to calculate
7 VID header offsets. Without this, uboot and linux
8 disagrees about the layout and refuse to attach
9 the ubi volume created by the other.
