From bda21477f523622a2c904a3fa80fd6b485b22bff Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Tue, 28 Jan 2025 10:45:18 +0000 Subject: hw/sd: Remove unused legacy functions, stop killing mammoths MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The sdcard_legacy.h header defines function prototypes for the "legacy" SD card API, which was used by non-qdevified SD controller models. We've now converted the only remaining non-qdev SD controller, so we can drop the legacy API. Entirely unused functions: sd_init(), sd_set_cb(), sd_enable() Functions which now become static inside sd.c (they are the underlying implementations of methods on SDCardClass): sd_do_command(), sd_write_byte(), sd_read_byte() Removal of sd_init() means that we can also remove the me_no_qdev_me_kill_mammoth_with_rocks flag, the codepaths that were only reachable when it was set, and the inserted_cb and readonly_cb qemu_irq lines that went with that.
