From ce14710f4fdfca32123d7efd3ddcbee984ef0ae5 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Fri, 8 Mar 2019 10:46:10 +0100 Subject: [PATCH] pflash: Clean up after commit 368a354f02b, part 2 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Our pflash devices are simplistically modelled has having "num-blocks" sectors of equal size "sector-length". Real hardware commonly has sectors of different sizes. How our "sector-length" property is related to the physical device's multiple sector sizes is unclear. Helper functions pflash_cfi01_register() and pflash_cfi02_register() create a pflash device, set properties including "sector-length" and "num-blocks", and realize. They take parameters @size, @sector_len and @nb_blocs. QOMification left parameter @size unused. Obviously, @size should match @sector_len and @nb_blocs, i.e. size == sector_len * nb_blocs. All callers satisfy this. Remove @nb_blocs and compute it from @size and @sector_len.
