These are already-documented common bindings for NAND chips. Let's
handle them in nand_base.
If NAND controller drivers need to act on this data before bringing up
the NAND chip (e.g., fill out ECC callback functions, change HW modes,
etc.), then they can do so between calling nand_scan_ident() and
nand_scan_tail().

For most of architectures in U-Boot, virtual address is straight
mapped to physical address. So, it makes sense to have generic
defines of ioremap and friends in <linux/io.h>.
All of them are just empty and will disappear at compile time, but
they will be helpful to implement drivers which are counterparts of
Linux ones.
I notice MIPS already has its own implementation, so I added a
Kconfig symbol CONFIG_HAVE_ARCH_IOREMAP which MIPS (and maybe
Sandbox as well) can select.

The previous commit introduced a useful macro used in makefiles,
in order to reference to different variables (CONFIG_... or
CONFIG_SPL_...) depending on the build context.
Per-image config option control is a PITA in C sources, too.
Here are some macros useful in C/CPP expressions.
CONFIG_IS_ENABLED(FOO) can be used as a shorthand for
(!defined(CONFIG_SPL_BUILD) && defined(CONFIG_FOO)) || \
(defined(CONFIG_SPL_BUILD) && defined(CONFIG_SPL_FOO))
For example, it is useful to describe C code as follows,
#if CONFIG_IS_ENABLED(OF_CONTROL)
(device tree code)
#else
(board file code)
#endif
The ifdef conditional above is switched by CONFIG_OF_CONTROL during
the U-Boot proper building (CONFIG_SPL_BUILD is not defined), and by
CONFIG_SPL_OF_CONTROL during SPL building (CONFIG_SPL_BUILD is
defined).
The macro can be used in C context as well, so you can also write the
equivalent code as follows:
if (CONFIG_IS_ENABLED(OF_CONTROL)) {
(device tree code)
} else {
(board file code)
}
Another useful macro is CONFIG_VALUE().
CONFIG_VALUE(FOO) is expanded into CONFIG_FOO if CONFIG_SPL_BUILD is
undefined, and into CONFIG_SPL_FOO if CONFIG_SPL_BUILD is defined.
You can write as follows:
text_base = CONFIG_VALUE(TEXT_BASE);
instead of:
#ifdef CONFIG_SPL_BUILD
text_base = CONFIG_SPL_TEXT_BASE;
#else
text_base = CONFIG_TEXT_BASE;
#endif
This commit also adds slight hacking on fixdep so that it can
output a correct list of fixed dependencies.
If the fixdep finds CONFIG_IS_ENABLED(FOO) in a source file,
we want
$(wildcard include/config/foo.h)
in the U-boot proper building context, while we want
$(wildcard include/config/spl/foo.h)
in the SPL build context.

Enable GPMC's prefetch feature for NAND access. This speeds up NAND read
access a lot by pre-fetching contents in the background and reading them
through the FIFO address.
The current implementation has two limitations:
a) it only works in 8-bit mode
b) it only supports read access
Both is easily fixable by someone who has hardware to implement it.
Note that U-Boot code uses non word-aligned buffers to read data into, and
request read lengths that are not multiples of 4, so both partial buffers
(head and tail) have to be addressed.

The libc headers on FreeBSD and likely related projects as well contain an
header file, cdefs.h which provides similiar functionality as linux/compiler.h.
It provides compiler independent defines like __weak __packed, to allow
compiling with multiple compilers which might have a different syntax for such
extension.
Since that header file is included in multiple standard headers, like stddef.h
and stdarg.h, multiple definitions of those defines will be present if both are
included. When compiling u-boot the compiler will warn about it hundreds of
times since e.g. common.h will include both files indirectly.
commit 7ea50d5284 "compiler_gcc: do not redefine

This patch add support for BCH16_ECC to omap_gpmc driver.
*need to BCH16 ECC scheme*
With newer SLC Flash technologies and MLC NAND, and large densities, pagesizes
Flash devices have become more suspectible to bit-flips. Thus stronger
ECC schemes are required for protecting the data.
But stronger ECC schemes have come with larger-sized ECC syndromes which require
more space in OOB/Spare. This puts constrains like;
(a) BCH16_ECC can correct 16 bit-flips per 512Bytes of data.
(b) BCH16_ECC generates 26-bytes of ECC syndrome / 512B.
Due to (b) this scheme can only be used with NAND devices which have enough
OOB to satisfy following equation:
OOBsize per page >= 26 * (page-size / 512)

*Section: Bus Width Requirements*
"When the host supports a 16-bit bus width, only data is transferred at the
16-bit width. All address and command line transfers shall use only the lower
8-bits of the data bus. During command transfers, the host may place any value
on the upper 8-bits of the data bus. During address transfers, the host shall
set the upper 8-bits of the data bus to 00h."

mtd: nand: force NAND_CMD_READID onto 8-bit bus
Author: Brian Norris <computersforpeace@gmail.com> (preserving authorship)
The NAND command helpers tend to automatically shift the column address
for x16 bus devices, since most commands expect a word address, not a
byte address. The Read ID command, however, expects an 8-bit address
(i.e., 0x00, 0x20, or 0x40 should not be translated to 0x00, 0x10, or
0x20).
This fixes the column address for a few drivers which imitate the
nand_base defaults.

Changes from Prabhabkar's version (squashed into one patch to preserve

- Added _LARGE to MTD_MAX_*_ENTRIES
This makes the names match current Linux source, and resolves
a conflict between
http://patchwork.ozlabs.org/patch/280488/
and
http://patchwork.ozlabs.org/patch/284513/
The former was posted first and is closer to matching Linux, but
unlike Linux it does not add _LARGE to the names. The second adds
_LARGE to one of the names, and depends on it in a subsequent patch
(http://patchwork.ozlabs.org/patch/284512/).
- Made max oobfree/eccpos configurable, and used this on tricorder,
alpr, ASH405, T4160QDS, and T4240QDS (these boards failed to build
for me without doing so, due to a size increase).
On tricorder SPL, this saves 2576 bytes (and makes the SPL build
again) versus the new default of 640 eccpos and 32 oobfree, and
saves 336 bytes versus the old default of 128 eccpos and 8 oobfree.

Linux modified the MTD driver interface in commit edbc4540 (with the
same name as this commit). The effect is that calls to mtd_read will
not return -EUCLEAN if the number of ECC-corrected bit errors is below
a certain threshold, which defaults to the strength of the ECC. This
allows -EUCLEAN to stop indicating "some bits were corrected" and begin
indicating "a large number of bits were corrected, the data held in
this region of flash may be lost soon". UBI makes use of this and when
-EUCLEAN is returned from mtd_read it will move data to another block
of flash. Without adopting this interface change UBI on U-boot attempts
to move data between blocks every time a single bit is corrected using
the ECC, which is a very common occurance on some devices.
For some devices where bit errors are common enough, UBI can get stuck
constantly moving data around because each block it attempts to use has
a single bit error. This condition is hit when wear_leveling_worker
attempts to move data from one PEB to another in response to an
-EUCLEAN/UBI_IO_BITFLIPS error. When this happens ubi_eba_copy_leb is
called to perform the data copy, and after the data is written it is
read back to check its validity. If that read returns UBI_IO_BITFLIPS
(in response to an MTD -EUCLEAN) then ubi_eba_copy_leb returns 1 to
wear_leveling worker, which then proceeds to schedule the destination
PEB for erasure. This leads to erase_worker running on the PEB, and
following a successful erase wear_leveling_worker is called which
begins this whole cycle all over again. The end result is that (without
UBI debug output enabled) the boot appears to simply hang whilst in
reality U-boot busily works away at destroying a block of the NAND
flash. Debug output from this situation:
UBI DBG: ensure_wear_leveling: schedule scrubbing

This patch adopts the interface change as in Linux commit edbc4540 in
order to avoid such situations. Given that none of the drivers under
drivers/mtd return -EUCLEAN, this should only affect those using
software ECC. I have tested that it works on a board which is
currently out of tree, but which I hope to be able to begin
upstreaming soon.

The modelist data uses the list definition but the 'list.h' header
were not being included. The build failure is bellow:

Only the <linux/usb/gadget.h> requires error.h include. Hence, several
includes of error.h at USB gadget functions are not needed.
Moreover unnecessary malloc.h includes were also removed.

usb: gadget: use dev_get_platdata()
Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly.

gcc allows extensions to be non compiler specific by defining
__* macros for the attributes supported by gcc. Having a
different definition causes many warnings during the build
(cdefs.h on FreeBSD uses __attribute((__pure__)) where u-boot
uses __attribute__((pure)) for example). Do not redefine
these macros to suppress these warnings.
This patch ignores the checkpatch warning:
WARNING: __packed is preferred over __attribute__((packed))

Since kernel code current use many dev_xxx() instead of using printk. To
compatible, move those dev_xxx from usb driver to linux/compat.h. Then all
driver code can use dev_err, dev_info and dev_vdbg.
This patch also removed duplicated macro definitions in usb driver.

reason is that in the "struct usb_composite_dev" the
"struct usb_device_descriptor desc;" is on an odd address,
and this struct gets accessed in
drivers/usb/gadget/composite.c device_qual()
Fix it, by align this var "struct desc" fix to an aligned
address.
