hw/block/nand: Decommission the NAND museum
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. The MTD subsystem is out of budget for Kconfig
options and already has too many of them, and there is a general
kernel trend to simplify the configuration menu.
We remove the stone age exhibits along with closing the museum,
but some of the iron age ones are transferred to the regular NAND
depot. Namely, only those which have unique device IDs are
transferred, and the ones which have conflicting device IDs are
removed.
The machine using this device are:
- axis-dev88
- tosa (via tc6393xb_init)
- spitz based (akita, borzoi, terrier)
