f8c987f8f1 lib: Add hexdump
Often during debugging session it's very interesting to see
what data we were dealing with. For example what we write or read
to/from memory or peripherals.

This change introduces functions that allow to dump binary
data with one simple function invocation like:
------------------->8----------------
print_hex_dump_bytes("", DUMP_PREFIX_OFFSET, buf, len);
------------------->8----------------

which gives us the following:
------------------->8----------------

65c3d25a6a ubi: fastmap: Implement produce_free_peb()
Since 'commit f82290afc8 ("mtd: ubi: Fix worker handling")',
when booting from NAND, on a fresh NAND just after being flashed (and
only in this case), we got the following log:

ubi0: default fastmap pool size: 200
ubi0: default fastmap WL pool size: 100
ubi0: attaching mtd2
ubi0: scanning is finished
ubi0 error: ubi_update_fastmap: could not find any anchor PEB
ubi0 error: ubi_update_fastmap: could not find any anchor PEB
ubi0 error: ubi_wl_get_peb: Unable to get a free PEB from user WL pool
ubi0 error: autoresize: cannot auto-resize volume 1
UBI error: cannot attach mtd2UBI error: cannot initialize UBI, error
-28UBI init error 28

After analysis, in ubi_wl_init(), when performing schedule_erase(),
thread_enabled flag is not yet set to 1, which forbids ubi_do_worker()
to execute pending works.

This has to effect to not populate ubi->free with free physical
eraseblocks.

Following Richard Weinberger's advice, this patch has been
backported from kernel tree :
'commit 1cb8f9776c7d ("ubi: fastmap: Implement produce_free_peb()")'

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

f82290afc8 mtd: ubi: Fix worker handling
Fixes a bug found on thuban boards, which were for 2 years in

Reason is, that accidentially the U-Boot implementation
from __schedule_ubi_work() did not check the flag
ubi->thread_enabled and started with wearleveling work,
but ubi did not have setup all structures at this point
and crashes.

Solve this problem by splitting work scheduling and processing.

68fc449033 mtd, ubi: set free_count to zero before walking through erase list
Set free_count to zero before walking through ai->erase list
in wl_init().

As U-Boot has no workqueue/threads, it immediately calls
erase_worker(), which increase for each erased block
free_count. Without this patch, free_count gets after
this initialized to zero in wl_init(), so the free_count
variable always has the maybe wrong value 0.

Detected this behaviour on the dxr2 board, where the
UBI fastmap gets not written when attaching/dettaching
on an empty NAND. It drops instead the error message:

could not find any anchor PEB

With this patch, fastmap gets written on dettach.

84b8bf6d5d bug.h: move BUILD_BUG_* defines to include/linux/bug.h
BUILD_BUG_* macros have been defined in several headers.  It would
be nice to collect them in include/linux/bug.h like Linux.

This commit is cherry-picking useful macros from include/linux/bug.h
of Linux 4.4.

I did not import BUILD_BUG_ON_MSG() because it would not work if it
is used with include/common.h in U-Boot.  I'd like to postpone it
until the root cause (the "error()" macro in include/common.h causes
the name conflict with "__attribute__((error()))") is fixed.

3b61297024 kbuild: force to define __UBOOT__ in all the C sources
U-Boot has imported various source files from other projects,
mostly Linux.

Something like

  #ifdef __UBOOT__
    [ modification for U-Boot ]
  #else
    [ original code ]
  #endif

is an often used strategy for clarification of adjusted parts,
that is, easier re-sync in future.

Instead of defining __UBOOT__ in each source file,
passing it from the top Makefile would be easier.

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.

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:

d63894654d UBI: init eba tables before wl when attaching a device
This fixes that u-boot gets stuck when a bitflip was detected
during "ubi part <ubi_device>". If a bitflip was detected UBI tries
to copy the PEB to a different place. This needs that the eba table
are initialized, but this was done after the wear levelling worker
detects the bitflip. So changes the initialisation of these two
tasks in u-boot.

This is a u-boot specific patch and not needed in the linux layer,
because due to commit 1b1f9a9d00
UBI: Ensure that "background thread" operations are really executed
we schedule these tasks in place and not as in linux after the inital
task which schedule this new task is finished.

6d8962e814 Switch from archive libraries to partial linking
Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils.  As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o".  This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols.  Known such cases include:
- disabling CMD_NET but not CMD_NFS;

ceeba00308 UBI: initialise update marker
UBI: initialise update marker

The in kernel copy of a volume's update marker is not initialised from the
volume table. This means that volumes where an update was unfinnished will
not be treated as "forbidden to use". This is basically that the update
functionality was broken.

1b1f9a9d00 UBI: Ensure that "background thread" operations are really executed
The current U-Boot UBI implementation is copied from Linux. In this
porting the UBI background thread was not handled correctly. Upon write
operations ubi_wl_flush() makes sure, that all queued operations, like
page-erase, are completed. But this is missing for read operations.

This patch now makes sure that such operations (like scrubbing upon
bit-flip errors) are not queued, but executed directly.

d318d0c44d UBI: Fix build problem noticed on Apollon (arm/testing repo)
This patch fixes a build problem noticed on Apollon by using
mtd_dev_by_eb() instead of "/" as done in the Linux UBI version.
So this brings the U-Boot UBI version more in sync with the Linux
version again.

60cfe87bd3 UBI: Add compile-time check for correct malloc area configuration
UBI is quite memory greedy and requires at least approx. 512k of malloc
area. This patch adds a compile-time check, so that boards will not
build with less memory reserved for this area (CONFIG_SYS_MALLOC_LEN).

c91a719daa UBI: Add basic UBI support to U-Boot (Part 5/8)
This patch adds basic UBI (Unsorted Block Image) support to U-Boot.
It's based on the Linux UBI version and basically has a "OS"
translation wrapper that defines most Linux specific calls
(spin_lock() etc.) into no-ops. Some source code parts have been
uncommented by "#ifdef UBI_LINUX". This makes it easier to compare
this version with the Linux version and simplifies future UBI
ports/bug-fixes from the Linux version.
