ar71xx: Add eTactica EG-200 support
[openwrt/staging/wigyori.git] / package / boot / kobs-ng / patches / 004-fix-cal_nfc_geometry.patch
1 The Freescale downstream vendor kernel has a patch that exports the bch
2 flash geometry via a debugfs file. This is not available in mainline linux
3 kernels so the fallback method calculates the geometry based on known info
4 from the mtd partition. A bug exists in this funcion where it fails to
5 assume that block0 ECC is the same as the other blocks by default.
