What is OTP in OneNAND?
The device includes,
1. one block-sized OTP (One Time Programmable) area and
2. user-controlled 1st block OTP(Block 0)
that can be used to increase system security or to provide
identification capabilities.What is done?
In OneNAND, one block of the NAND Array is set aside as an OTP
memory area, and 1st Block (Block 0) can be used as OTP area.
This area, available to the user, can be configured and locked
with secured user information. The OTP block can be read,
programmed and locked using the same operations as any other NAND
Flash Array memory block. After issuing an OTP-Lock, OTP block
cannot be erased. OTP block is fully-guaranteed to be a good
block.Why it is done?
Locking the 1st Block OTP has the effect of a 'Write-protect' to
guard against accidental re-programming of data stored in the 1st
block and OTP Block.Which problem it solves?
OTP support is provided in the existing implementation of
OneNAND/Flex-OneNAND driver, but it is not working with OneNAND
devices. Have observed the following in current OTP OneNAND Implmentation,
1. DataSheet specific sequence to lock the OTP Area is not followed.
2. Certain functions are quiet generic to cope with OTP specific activity.
This patch re-implements OTP support for OneNAND device.How it is done?
For all blocks, 8th word is available to the user.
However, in case of OTP Block, 8th word of sector 0, page 0 is reserved as
OTP Locking Bit area. Therefore, in case of OTP Block, user usage on this
area is prohibited. Condition specific values are entered in the 8th word,
sector0, page 0 of the OTP block during the process of issuing an OTP-Lock.
The possible conditions are:
1. Only 1st Block Lock
2. Only OTP Block Lock
3. Lock both the 1st Block and the OTP BlockWhat Other feature additions have been done in this patch?
This patch adds feature for:
1. Only 1st Block Lock
2. Lock both the 1st Block and the OTP BlocksRe-implemented OTP support for OneNAND
Added following features to OneNAND
1. Lock only 1st Block in OneNAND
2. Lock BOTH 1st Block and OTP Block in OneNAND[comments were slightly tweaked by Artem]

Remove the ARM dependency from the generic "onenand" platform device
driver. This change makes the driver useful for other architectures as
well. Needed for the SuperH kfr2r09 board.Apart from the obvious Kconfig bits, the most important change is the move
away from ARM specific includes and platform data. Together with this
change the only in-tree board code gets an update, and the driver name is
also changed gracefully break potential out of tree drivers.The driver is also updated to allow NULL as platform data together with a
few changes to make use of resource_size() and dev_name().Signed-off-by: Magnus Damm

This patch fixes the bug reported in
http://bugzilla.kernel.org/show_bug.cgi?id=11681."Lots of device drivers register a 'struct device_driver' with
the '.bus' member set to '&platform_bus_type'. This is wrong,
since the platform_bus functions expect the 'struct device_driver'
to be wrapped up in a 'struct platform_driver' which provides
some additional callbacks (like suspend_late, resume_early).
The effect may be that platform_suspend_late() uses bogus data
outside the device_driver struct as a pointer pointer to the
device driver's suspend_late() function or other hard to
reproduce failures."(Lothar Wassmann)Signed-off-by: Ming Lei

This patch replaces some legacy OMAP GPIO calls with the "new" (not
really, any more!) calls that work on most platforms.The calls addressed by this patch are the simple ones to get and set
values ... for code that's in mainline, including the implementations
of those calls.Except for the declarations and definitions of those calls, all of
these changes were performed by a simple SED script. Plus, a few
"if() set() else set()" branches were merged by hand.Signed-off-by: David Brownell

MTD internal API presently uses 32-bit values to represent
device size. This patch updates them to 64-bits but leaves
the external API unchanged. Extending the external API
is a separate issue for several reasons. First, no one
needs it at the moment. Secondly, whether the implementation
is done with IOCTLs, sysfs or both is still debated. Thirdly
external API changes require the internal API to be accepted
first.Note that although the MTD API will be able to support 64-bit
device sizes, existing drivers do not and are not required
to do so, although NAND base has been updated.In general, changing from 32-bit to 64-bit values cause little
or no changes to the majority of the code with the following
exceptions:
- printk message formats
- division and modulus of 64-bit values
- NAND base support
- 32-bit local variables used by mtdpart and mtdconcat
- naughtily assuming one structure maps to another
