Subject: mtd: Handle 29LV800BT
X-Git-Tag: v2015.01-rc2~52
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=f3c89d9228157933cf3e34d09b54ea362a6d8838;p=oweals%2Fu-boot.git

mtd: Handle 29LV800BT

The device id makes u-boot think that this chip needs
cfi_reverse_geometry(), which is not the case.
Add it to jedec_flash, so it is handled properly.
