From 9d1cc1d0942b12587c9218661b78fdd7d5e508f4 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Philippe=20Mathieu-Daud=C3=A9?= Date: Mon, 14 Dec 2020 01:26:20 +0100 Subject: [PATCH] hw/block/nand: Decommission the NAND museum MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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) Reviewed-by: Richard Henderson Signed-off-by: Philippe Mathieu-Daudé Message-Id: <20201214002620.342384-1-f4bug@amsat.org> Reviewed-by: Peter Maydell Signed-off-by: Kevin Wolf --- hw/block/nand.c | 12 +----------- 1 file changed, 1 insertion(+), 11 deletions(-) diff --git a/hw/block/nand.c b/hw/block/nand.c index 1d7a48a2ec..9ed54a0a92 100644 --- a/hw/block/nand.c +++ b/hw/block/nand.c @@ -137,7 +137,7 @@ static void mem_and(uint8_t *dest, const uint8_t *src, size_t n) # define ADDR_SHIFT 16 # include "nand.c" -/* Information based on Linux drivers/mtd/nand/nand_ids.c */ +/* Information based on Linux drivers/mtd/nand/raw/nand_ids.c */ static const struct { int size; int width; @@ -147,21 +147,11 @@ static const struct { } nand_flash_ids[0x100] = { [0 ... 0xff] = { 0 }, - [0x6e] = { 1, 8, 8, 4, 0 }, - [0x64] = { 2, 8, 8, 4, 0 }, [0x6b] = { 4, 8, 9, 4, 0 }, - [0xe8] = { 1, 8, 8, 4, 0 }, - [0xec] = { 1, 8, 8, 4, 0 }, - [0xea] = { 2, 8, 8, 4, 0 }, - [0xd5] = { 4, 8, 9, 4, 0 }, [0xe3] = { 4, 8, 9, 4, 0 }, [0xe5] = { 4, 8, 9, 4, 0 }, [0xd6] = { 8, 8, 9, 4, 0 }, - - [0x39] = { 8, 8, 9, 4, 0 }, [0xe6] = { 8, 8, 9, 4, 0 }, - [0x49] = { 8, 16, 9, 4, NAND_BUSWIDTH_16 }, - [0x59] = { 8, 16, 9, 4, NAND_BUSWIDTH_16 }, [0x33] = { 16, 8, 9, 5, 0 }, [0x73] = { 16, 8, 9, 5, 0 },
