0d4c1c91bb include/linux/compat.h: fix warning: preprocessor token {__iomem, __user} redefined

include/linux/compat.h:5:9: warning: preprocessor token __iomem redefined
include/linux/compiler.h:12:10: this was the original definition

fixup __iomem, __user definitions in compat.h code appears to be placed
there as a cover up from a code import from linux when u-boot didn't yet
have a compiler.h, introduced by commit
932394ac43 "Rewrite of NAND code based on
what is in 2.6.12 Linux kernel".

eef1cf2d5c include/linux/byteorder: import latest endian definitions from linux
u-boot's byteorder headers did not contain endianness attributions
for use with sparse, causing a lot of false positives.  Import the
kernel's latest definitions, and enable them by including compiler.h
and types.h.  They come with 'const' added for some swab functions, so
fix those up, too:

include/linux/byteorder/big_endian.h:46:2: warning: passing argument 1 of '__swab64p' discards 'const' qualifier from pointer target type [enabled by default]

Also, note: u-boot's historic __BYTE_ORDER definition has been
preserved (for the time being at least).

We also remove ad-hoc barrier() definitions, since we're including
compiler.h in files that hadn't in the past:

macb.c:54:0: warning: "barrier" redefined [enabled by default]

In addition, including compiler.h in byteorder changes the 'noinline'
definition to expand to __attribute__((noinline)).  This fixes
arch/powerpc/lib/bootm.c:

bootm.c:329:16: error: attribute '__attribute__': unknown attribute
bootm.c:329:16: error: expected ')' before '__attribute__'
bootm.c:329:25: error: expected identifier or '(' before ')' token

powerpc sparse builds yield:

include/common.h:356:22: error: marked inline, but without a definition

the unknown-reason inlining without a definition is considered obsolete
given it was part of the 2002 initial commit, and no arm version was
'fixed.'

also fixed:
ydirectenv.h:60:0: warning: "inline" redefined [enabled by default]

9aed508083 COMMON: Add __stringify() function
Copied from Linux kernel:
commit 8f7c2c37319a81ef4c2bfdec67b1ccd5744d97e4
Date:   Wed Apr 8 16:58:57 2009 +0800

Pull in the __stringify() macro from Linux kernel. This macro is usually used to
convert numbers to strings at preprocessor level, yet it is not limited only to
that. This is useful as it allows higher usage of puts() in favour of printf().

9c790a748f mtd: nand: allow NAND_NO_SUBPAGE_WRITE to be set from driver
This is based on Linux kernel -next:

commit 14f44abf1dafc20ba42ce8616a8fc8fbd1b3712b
Author: Brian Norris <computersforpeace@gmail.com>
Date:   Fri Jul 13 09:28:24 2012 -0700

    mtd: nand: allow NAND_NO_SUBPAGE_WRITE to be set from driver

    The NAND_CHIPOPTIONS_MSK has limited utility and is causing real bugs. It
    silently masks off at least one flag that might be set by the driver
    (NAND_NO_SUBPAGE_WRITE). This breaks the GPMI NAND driver and possibly
    others.

    Really, as long as driver writers exercise a small amount of care with
    NAND_* options, this mask is not necessary at all; it was only here to
    prevent certain options from accidentally being set by the driver. But the
    original thought turns out to be a bad idea occasionally. Thus, kill it.

    Note, this patch fixes some major gpmi-nand breakage.

Earlier, a driver exists in the u-boot source code for the SMI IP. However, it
was specific to spear platforms. This commit converts the same driver to a more
generic driver. As a result, the driver files are renamed to st_smi.c and
st_smi.h and moved into drivers/mtd folder for reusability by other platforms
using smi controller peripheral.

This reverts commit 4fee6c2f29.

It breaks boards that currently rely on soft-ecc, as pointed out here:
http://patchwork.ozlabs.org/patch/140872/

The reverted patch should be resubmitted with documentation, and with the
CONFIG_MTD_ECC_SOFT selected from every board that needs it.  We could
start by looking at what NAND driver the board selects, and whether
that driver ever asks for soft ECC.

93337abbfe Add isblank
Existing ctype checks are implemented using a 256 byte lookup table,
allowing each character to be in any of 8 character classes. Since there
are 8 existing character classes without the blank class, I implemented
isblank without using the lookup table.  Since there are only two blank
characters - tab and space - this is a more reasonable approach than
doubling the size of the lookup table to accommodate one more class.

1) It had a boolean logic error in checking the MMD mask, and
always checked all of them.

2) It checked devices which don't actually report link state, which
meant that it would never believe the link was fully up.

Fix the boolean logic, and then mask the MMD mask so only link-reporting
devices are checked.

5f184715ec Create PHY Lib for U-Boot
Extends the mii_dev structure to participate in a full-blown MDIO and
PHY driver scheme.  The mii_dev structure and miiphy calls are modified
in such a way to allow the original mii command and miiphy
infrastructure to work as before, but also to support a new set of APIs
which allow (among other things) sharing of PHY driver code and 10G support

The mii command will continue to support normal PHY management functions
(Clause 22 of 802.3), but will not be changed to support 10G
(Clause 45).

The basic design is similar to PHY Lib from Linux, but simplified for
U-Boot's network and driver infrastructure.

We now have MDIO drivers and PHY drivers

An MDIO driver provides:
read
write
reset

A PHY driver provides:
(optionally): probe
config - initial setup, starting of auto-negotiation
startup - waiting for AN, and reading link state
shutdown - any cleanup needed

The ethernet drivers interact with the PHY Lib using these functions:
phy_connect()
phy_config()
phy_startup()
phy_shutdown()

Each PHY driver can be configured separately, or all at once using
config_phylib_all_drivers.h (added in the patch which adds the drivers)

We also provide generic drivers for Clause 22 (10/100/1000), and
Clause 45 (10G) PHYs.

We also implement phy_reset(), and call it in phy_connect(). Because
phy_reset() is essentially the same as miiphy_reset, but:
a) must support 10G PHYs, and
b) should use the phylib primitives,

we implement miiphy_reset, using phy_reset(), but only when
CONFIG_PHYLIB is set. Otherwise, we just use the old version. In this
way, we save on compile size, even if we don't manage to save code size.

16a354f920 include/asm-offsets.h: automatically generate assembler constants
A recurrent issue is that certain C level constructs like sizeof() or
offsetof() cannot be used in assembler files, which is inconvenient
when such constructs are used in the definition of macro names etc.

To avoid duplication of such definitions (and thus another cause of
problems), we adapt the Linux way to automatically generate the
respective definitions from the respective C header files.

In Linux, this is implemented in include/linux/kbuild.h, Kbuild, and
arch/*/kernel/asm-offsets.c; we adapt the code from the Linux v2.6.36
kernel tree.

We also copy the concept of the include/generated/ directory which can
be used to hold other automatically generated files as well.

We start with an architecture-independent lib/asm-offsets.c which
generates include/generated/generic-asm-offsets.h (included by
include/asm-offsets.h, which is what will be referred to in the actual
source code).  Later this may be extended by architecture-specific
arch/*/lib/asm-offsets.c files that will generate a
include/generated/asm-offsets.h.

4ba692fb1e mtd: add an mtd method for get_len_incl_bad()
The logic to 'spread' mtd partitions needs to calculate the length in
the mtd device, including bad blocks.

This patch introduces a new function, mtd_get_len_incl_bad that can
return both the length including bad blocks and whether that length
was truncated on the device. This new function will be used by the
mtdparts spread command later in this series. The definition of the
function is #ifdef'd out in configurations that do not use the new
'mtdparts spread' command.

Get rid of the several "#if 0" sections that were keeping around Linux
code that isn't relevant to U-Boot.  Besides cluttering the code, these
sections make tracking upstream changes harder, rather than easier.
It's easy to discard obviously irrelevant diff hunks that patch rejects,
but it's not as easy to notice hunks that apply cleanly to the #if 0
section, but *are* relevant to U-Boot and require modification elsewhere.

Also remove suspend/resume, as this is not applicable to U-Boot.  Removal
saves 232 bytes on powerpc.

feeds the ECC from OOB area to the ECC hw engine and perform any
correction on the data as per the ECC status reported by the engine.

33846df28f Add wait flags to support board/chip specific delays
The NAND flash on the TQM8548_BE modules requires a short delay after
running the UPM pattern like the MPC8360ERDK board does. The TQM8548_BE
requires a further short delay after writing out a buffer. Normally the
R/B pin should be checked, but it's not connected on the TQM8548_BE.
The corresponding Linux FSL UPM driver uses similar delay points at the
same locations. To manage these extra delays in a more general way, I
introduced the "wait_flags" field allowing the board-specific driver to
specify various types of extra delay.

The U-Boot UBIFS implementation is largely a direct copy from the current
Linux version (2.6.29-rc6). As already done in the UBI version we have an
"abstraction layer" to redefine or remove some OS calls (e.g. mutex_lock()
...). This makes it possible to use the original Linux code with very
little changes. And by this we can better update to later Linux versions.

I removed some of the Linux features that are not used in the U-Boot
version (e.g. garbage-collection, write support).

b1b4e89a0f Add LZO decompressor support
This patch adds LZO decompression support to U-Boot. It is needed for
the upcoming UBIFS support, since UBIFS uses LZO as default compressor/
decompressor. Since we only support read-only in UBIFS, only the
decompressor is needed.

All this is copied with minor changes from the current Linux kernel
version (2.6.28-rc8).

This patch only implements this LZO decompressor support for PPC.
Other platforms using UBIFS will have to add the required
"include/asm/unaligned.h" as well. It should be fairly easy to copy this
from the Linux source tree as I have done it for PPC in this patch.

prevented compiling code for a board hosting both NAND and OneNAND chips.

c45912d8ab NAND: sync with 2.6.27
This brings the core NAND code up to date with the Linux kernel.

Since there were several drivers in Linux as of the last update that are
not in u-boot, I'm not bringing over new drivers that have been added
since in the absence of an interested party.

I did not update OneNAND since it was recently synced by Kyungmin Park,
and I'm not sure exactly what the common ancestor is.

cfa460adfd Update MTD to that of Linux 2.6.22.1
A lot changed in the Linux MTD code, since it was last ported from
Linux to U-Boot. This patch takes U-Boot NAND support to the level
of Linux 2.6.22.1 and will enable support for very large NAND devices
(4KB pages) and ease the compatibility between U-Boot and Linux
filesystems.

This patch is tested on two custom boards with PPC and ARM
processors running YAFFS in U-Boot and Linux using gcc-4.1.2
cross compilers.

MAKEALL ppc/arm has some issues:
 * DOC/OneNand/nand_spl is not building (I have not tried porting
   these parts, and since I do not have any HW and I am not familiar
   with this code/HW I think its best left to someone else.)

Except for the issues mentioned above, I have ported all drivers
necessary to run MAKEALL ppc/arm without errors and warnings. Many
drivers were trivial to port, but some were not so trivial. The
following drivers must be examined carefully and maybe rewritten to
some degree:
 cpu/ppc4xx/ndfc.c
 cpu/arm926ejs/davinci/nand.c
 board/delta/nand.c
 board/zylonite/nand.c

a75a57ef6e NAND FSL UPM: driver re-write using the hwcontrol callback
This is a re-write of the NAND FSL UPM driver using the more universal
hwcontrol callback (instead of the cmdfunc callback). Here is a brief
list of furher modifications:

- For the time being, the UPM setup writing the UPM array has been
  removed from the driver and must now be done by the board specific
  code.

- The bus width definition in "struct fsl_upm_nand" is now in bits to
  comply with the corresponding Linux driver and 8, 16 and 32 bit
  accesses are supported.

- chip->dev_read is only set if fun->dev_ready != NULL, which is
  required for boards not connecting the R/B pin.

- A few issue have been fixed with MxMR bit manipulation like in the
  corresponding Linux driver.

Note: I think the "io_addr" field of "struct fsl_upm" could be removed
      as well, because the address is already determined by
      "nand->IO_ADDR_[RW]", but I'm not 100% sure.

This patch has been tested on a TQM8548 modules with the NAND chip
Micron MT29F8G08FABWP.

This patch is based on the following patches posted to this list a few
minutes ago:

  PPC: add accessor macros to clear and set bits in one shot
  83xx/85xx/86xx: add more MxMR local bus definitions
