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.

This partially reverts commit 1696e6bc
("mtd: nand: kill NAND_NO_READRDY").

In that patch I overlooked a few things.

The original documentation for NAND_NO_READRDY included "True for all
large page devices, as they do not support autoincrement." I was
conflating "not support autoincrement" with the NAND_NO_AUTOINCR option,
which was in fact doing nothing. So, when I dropped NAND_NO_AUTOINCR, I
concluded that I then could harmlessly drop NAND_NO_READRDY. But of
course the fact the NAND_NO_AUTOINCR was doing nothing didn't mean
NAND_NO_READRDY was doing nothing...

So, NAND_NO_READRDY is re-introduced as NAND_NEED_READRDY and applied
only to those few remaining small-page NAND which needed it in the first
place.

According to its documentation, the NAND_NO_READRDY option is always used
when autoincrement is not supported. Autoincrement support was recently
dropped, so we can drop this options as well (defaulting to "no read ready
check").

Toshiba does not use ONFI for their NAND flash. So we have to continue
to add new IDs used by Toshiba devices as well as heuristic detection
for scanning the 2nd page for a BBM. This is a relatively harmless
start at supporting many of them.

These chips mostly follow the same ID fields of previous generations,
but there is a need for a tweak.

These chips introduce a strange 576 byte OOB (that's 36 bytes per
512 bytes of page). In the preliminary data, Toshiba has not
defined exactly how their ID strings should decode. In the future,
a new tweak must be added.

Data is taken from, among others, Toshiba TC58TxG4S2FBAxx

Included the basic size info for NAND chips with ID of 0xAD or
0xD7. The first can be found in Hynix HY27SF161G2M, while the
second can be found in Micron MT29F64G08 and the Samsung K9LBG08U0D
(among others). Also, some 64 Gbit (or larger) chips identify as
0xD7 because they contain multiple smaller 32 Gbit chips. I
assume it's safe to classify these under the 32 Gbit listing.

The nand driver has a superflous read ready / command
delay in the read functions. This was added to handle
chips which have an automatic read forward. Newer
chips do not have this functionality anymore. Add this
option to avoid the delay / I/O operation. Mark all
large page chips with the new option flag.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
