From 36aa285f48d55451bb2eb7a2c0f9635a3c2bbe46 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Wed, 17 Nov 2021 17:33:57 +0100 Subject: [PATCH] hw/sd/ssi-sd: Do not create SD card within controller's realize MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ssi_sd_realize() creates an "sd-card" device. This is inappropriate, and marked FIXME. Move it to the boards that create these devices. Prior art: commit eb4f566bbb for device "generic-sdhci", and commit 26c607b86b for device "pl181". The device remains not user-creatable, because its users should (and do) wire up its GPIO chip-select line.
