From c32c8dc8af9e971f91feaee145f1e8d6f114cad6 Mon Sep 17 00:00:00 2001 From: Nico Huber Date: Sun, 16 Jun 2019 19:46:46 +0200 Subject: layout: Introduce flashrom_layout_new() It initializes an empty layout. Currently the maximum number of entries has to be specified, which will vanish once we use dynamic allocation per entry. We replace the two special cases `single_layout` and `ich_layout` with dynamically allocated layouts. As a result, we have to take care to release the `default_layout` in a flashctx once we are done with it.
