From 11450469830f2481a9e7cb181609288d40f41323 Mon Sep 17 00:00:00 2001 From: Matias Bjørling Date: Mon, 16 Nov 2015 15:34:37 +0100 Subject: lightnvm: update bad block table format MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The specification was changed to reflect a multi-value bad block table. Instead of bit-based bad block table, the bad block table now allows eight bad block categories. Currently four are defined: * Factory bad blocks * Grown bad blocks * Device-side reserved blocks * Host-side reserved blocks The factory and grown bad blocks are the regular bad blocks. The reserved blocks are either for internal use or external use. In particular, the device-side reserved blocks allows the host to bootstrap from a limited number of flash blocks. Reducing the flash blocks to scan upon super block initialization. Support for both get bad block table and set bad block table is added.
