From 2c72404687f1061d042769cc65ef90e6c3da3f96 Mon Sep 17 00:00:00 2001 From: Steve Rae Date: Tue, 7 Jun 2016 11:19:38 -0700 Subject: fastboot: sparse: implement reserve() In order to process the CHUNK_TYPE_DONT_CARE properly, there is a requirement to be able to 'reserve' a specified number of blocks in the storage media. Because of the special handling of "bad blocks" in NAND devices, this is implemented in a storage abstraction function.
