The machine using this device are: - axis-dev88 - tosa (via tc6393xb_init) - spitz based (akita, borzoi, terrier) $ git grep nand_init hw/arm/spitz.c:223: s->nand = nand_init(nand ? blk_by_legacy_dinfo(nand) : NULL, hw/block/nand.c:641:DeviceState *nand_init(BlockBackend *blk, int manf_id, int chip_id) hw/cris/axis_dev88.c:278: nand_state.nand = nand_init(nand ? blk_by_legacy_dinfo(nand) : NULL, hw/display/tc6393xb.c:569: s->flash = nand_init(nand ? blk_by_legacy_dinfo(nand) : NULL, > > On 8/14/20 3:21 PM, Philippe Mathieu-Daudé wrote: >> This is the QEMU equivalent of this Linux commit (but 7 years later): >> https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=f7025a43a9da2 >> >> The MTD subsystem has its own small museum of ancient NANDs >> in a form of the CONFIG_MTD_NAND_MUSEUM_IDS configuration option. >> The museum contains stone age NANDs with 256 bytes pages, as well >> as iron age NANDs with 512 bytes per page and up to 8MiB page size. >> >> It is with great sorrow that I inform you that the museum is being >> decommissioned.
