643aae1406 include: delete include/linux/config.h
Linux Kernel abolished include/linux/config.h long time ago.
(around version v2.6.18..v2.6.19)

We don't need to provide Linux copatibility any more.

This commit deletes include/linux/config.h
and fixes source files not to include this.

Moving the usb/phy code from xhci-omap to the usb/phy directory

Newer TI processors adding xHCI support will have different PHY configurations
so therefore abstracting this code away will prevent messing around with the

40462e541d mtd: driver _read() returns max_bitflips; mtd_read() returns -EUCLEAN
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
  UBI DBG: wear_leveling_worker: scrub PEB 1027 to PEB 4083

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.

dfe64e2c89 mtd: resync with Linux-3.7.1
This patch is essentially an update of u-boot MTD subsystem to
the state of Linux-3.7.1 with exclusion of some bits:

- the update is concentrated on NAND, no onenand or CFI/NOR/SPI
flashes interfaces are updated EXCEPT for API changes.

- new large NAND chips support is there, though some updates
have got in Linux-3.8.-rc1, (which will follow on top of this patch).

To produce this update I used tag v3.7.1 of linux-stable repository.

The update was made using application of relevant patches,
with changes relevant to U-Boot-only stuff sticked together
to keep bisectability. Then all changes were grouped together
to this patch.

956b03e180 mtd: nand: add driver for diskonchip g4 nand flash
This patch adds a driver for the diskonchip G4 nand flash device.  It is based
on the driver from the linux kernel.

This also includes a separate SPL driver.  A separate SPL driver is used because
the device operates in a different mode (reliable mode) when loading a boot
image, and also because the storage format of the boot image is different from
normal data (pages are stored redundantly).  The SPL driver basically mimics how
a typical IPL reads data from the device.  The special operating mode and
storage format are used to compensate for the fact that the IPL does not contain
the BCH ecc decoding algorithm (due to size constraints).  Although the u-boot
SPL *could* use ecc, it operates like an IPL for the sake of simplicity and
uniformity, since the IPL and SPL share the task of loading the u-boot image.
As a side benefit, the SPL driver is very small.

eb81955bf0 musb-new: port of Linux musb driver
Existing U-Boot musb driver has no support for the new gadget framework
and also seems to have other limitations. As gadget framework is ported
from Linux it seems pretty natural to port musb gadget driver as well.

This driver supports both host and peripheral modes.

This is not a replacement for current musb driver (at least now) as
there are still some consumers of the old UDC interface.

No DMA operation support included, CONFIG_MUSB_PIO_ONLY should be
defined.

Virtual root hub device is not implemented.

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

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.

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.

5b8e6bb517 nand: remove dead code and suspend/resume
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.

20dde48bca add lzop decompression support
Add lzop decompression support to the existing lzo bitstream handling
(think gzip versus zlib), and support it for uImage decompression if
CONFIG_LZO is enabled.

Lzop doesn't compress as good as gzip (~10% worse), but decompression
is very fast (~0.7s faster here on a slow ppc). The lzop decompression
code is based on Albin Tonnerre's recent ARM Linux lzo support patch.

The asm-arm/unaligned.h includes linux/unaligned/access_ok.h
This file is unsafe to be used on ARM, since it does an unaligned memory
accesses which fails on ARM.

Lookin at Linux the basic difference seems to be the header
"include/asm-arm/unaligned.h". The Linux version of "unaligned.h"
does *not* include "access_ok.h" at all. It includes "le_byteshift.h"
and "be_byteshift.h" instead.
