aab616e31d mtd: kill the nand_ecclayout struct
Now that all MTD drivers have moved to the mtd_ooblayout_ops model we can
safely remove the struct nand_ecclayout definition, and all the remaining
places where it was still used.

abbbc60a0c mtd: pmc551: add __init attribute
Add __init attribute on a function that is only called from other __init
functions and that is not inlined, at least with gcc version 4.8.4 on an
x86 machine with allyesconfig.  Currently, the function is put in the
.text.unlikely segment.  Declaring it as __init will cause it to be put in
the .init.text and to disappear after initialization.

The result of objdump -x on the function before the change is as follows:

00000000000000c6 l     F .text.unlikely 000000000000091c fixup_pmc551

And after the change it is as follows:

0000000000000000 l     F .init.text	0000000000000917 fixup_pmc551

Done with the help of Coccinelle.  The semantic patch checks for local
static non-init functions that are called from an __init function and are
not called from any other function.

025ce02d92 mtd: maps: make uclinux.c driver more explicitly non-modular
The Kconfig for this support is currently declared with:

config MTD_UCLINUX
        bool "Generic uClinux RAM/ROM filesystem support"

...meaning that it currently is not being built as a module by anyone.
Lets remove as much of the modular evidence that we can, so that when
reading the driver there is less doubt it is builtin-only.

Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.

We also replace module.h with moduleparam.h since the file does use
a module_param,  and leaving it as such is currently the easiest way
to remain compatible with existing boot arg use cases.

We also delete the MODULE_LICENSE tag etc. since all that information
was (or is now) contained at the top of the file in the comments.

c5f9d6b137 physmap_of: ensure versatile code is reachable
With the newly added physmap_of_versatile code, we get a build error
when physmap_of is in a module, because of_flash_probe_versatile
is not exported:

ERROR: "of_flash_probe_versatile" [drivers/mtd/maps/physmap_of.ko] undefined!

This adds the export, and changes the Makefile so that the code is
also put into a loadable module rather than built-in when physmap_of
itself is a module.

adbbc3bc82 mtd: create an mtd_ooblayout_ops struct to ease ECC layout definition
ECC layout definitions are currently exposed using the nand_ecclayout
struct which embeds oobfree and eccpos arrays with predefined size.
This approach was acceptable when NAND chips were providing relatively
small OOB regions, but MLC and TLC now provide OOB regions of several
hundreds of bytes, which implies a non negligible overhead for everybody
even those who only need to support legacy NANDs.

Create an mtd_ooblayout_ops interface providing the same functionality
(expose the ECC and oobfree layout) without the need for this huge
structure.

The mtd->ecclayout is now deprecated and should be replaced by the
equivalent mtd_ooblayout_ops. In the meantime we provide a wrapper around
the ->ecclayout field to ease migration to this new model.
