From 306764ee3bfd312a17af1b69e5a263a2fe6e76cb Mon Sep 17 00:00:00 2001 From: Laszlo Ersek Date: Tue, 12 Sep 2023 17:55:53 +0200 Subject: [PATCH] hw/i386/pc: fix code comment on cumulative flash size MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - The comment is incorrectly indented / formatted. - The comment states a 8MB limit, even though the code enforces a 16MB limit. Both of these warts come from commit 0657c657eb37 ("hw/i386/pc: add max combined fw size as machine configuration option", 2020-12-09); clean them up. Arguably, it's also better to be consistent with the binary units (such as "MiB") that QEMU uses nowadays. Cc: "Michael S.
