In list "super_blocks" ubifs collects allocated super_block
structs. U-Boot frees on unmount the allocated struct,
so the pointer stored in this list is free after the umount.
On a new ubifs mount, the new allocated super_block struct
get inserted into the super_blocks list ... which contains
now a freed pointer, and the list_add_tail() corrupts the
freed memory ...
2 solutions are possible:
- remove the super_block from the super_blocks list
on umount
- as U-Boot does not use the super_blocks list ...
remove it complete for U-Boot.
Both solutions should not introduce problems for porting
to newer linux version, so this patch removes the unused
super_blocks list, as it saves code size and execution
time.

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.

At present malloc.h is included everywhere since it recently was added to
common.h in this commit:
4519668 mtd/nand/ubi: assortment of alignment fixes
This seems wasteful and unnecessary. We have been trying to trim down
common.h and put separate functions into separate header files and that
change goes in the opposite direction.
Move malloc_cache_aligned() to a new header so that this can be avoided.
The header would perhaps be better named as alignmem.h but it needs to be
included after common.h and people might be confused by this. With the name
memalign.h it fits nicely after malloc() in most cases.

U-Boot has imported various utility macros from Linux
scattering them to various places without consistency.
In include/common.h are min, max, min3, max3, ARRAY_SIZE, ALIGN,
container_of, DIV_ROUND_UP, etc.
In include/linux/compat.h are min_t, max_t, round_up, round_down,
etc.
We also have duplicated defines of min_t in some *.c files.
Moreover, we are suffering from too cluttered include/common.h.
This commit moves various macros that originate in
include/linux/kernel.h of Linux to their original position.
Note:
This commit simply moves the macros; the macros roundup,
min, max, min2, max3, ARRAY_SIZE are different
from those of Linux at this point.

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.

When we tell the compiler to optimize for ARMv7 (and ARMv6 for that
matter) it assumes a default of SCTRL.A being cleared and unaligned
accesses being allowed and fast at the hardware level. We set this bit
and must pass along -mno-unaligned-access so that the compiler will
still breakdown accesses and not trigger a data abort.
To better help understand the requirements of the project with respect
to unaligned memory access, the
Documentation/unaligned-memory-access.txt file has been added as
doc/README.unaligned-memory-access.txt and is taken from the v3.14-rc1
tag of the kernel.

Now we are ready to switch over to real Kbuild.
This commit disables temporary scripts:
scripts/{Makefile.build.tmp, Makefile.host.tmp}
and enables real Kbuild scripts:
scripts/{Makefile.build,Makefile.host,Makefile.lib}.
This switch is triggered by the line in scripts/Kbuild.include
-build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj
+build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj
We need to adjust some build scripts for U-Boot.
But smaller amount of modification is preferable.
Additionally, we need to fix compiler flags which are
locally added or removed.
In Kbuild, it is not allowed to change CFLAGS locally.
Instead, ccflags-y, asflags-y, cppflags-y,
CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o
are prepared for that purpose.

This commit changes the working directory
where the build process occurs.
Before this commit, build process occurred under the source
tree for both in-tree and out-of-tree build.
That's why we needed to add $(obj) prefix to all generated
files in makefiles like follows:
$(obj)u-boot.bin: $(obj)u-boot
Here, $(obj) is empty for in-tree build, whereas it points
to the output directory for out-of-tree build.
And our old build system changes the current working directory
with "make -C <sub-dir>" syntax when descending into the
sub-directories.
On the other hand, Kbuild uses a different idea
to handle out-of-tree build and directory descending.
The build process of Kbuild always occurs under the output tree.
When "O=dir/to/store/output/files" is given, the build system
changes the current working directory to that directory and
restarts the make.
Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>"
syntax for descending into sub-directories.
(We can write it like "make $(obj)=<sub-dir>" with a shorthand.)
This means the current working directory is always the top
of the output directory.

UBI can mount volumes by name or number The current code forces you
to name the volume by prepending every name with "ubi:".
>From fs/ubifs/super.c
* There are several ways to specify UBI volumes when mounting UBIFS:
* o ubiX_Y - UBI device number X, volume Y;
* o ubiY - UBI device number 0, volume Y;
* o ubiX:NAME - mount UBI device X, volume with name NAME;
* o ubi:NAME - mount UBI device 0, volume with name NAME.
Now any name passed in any of the above forms are allowed.
Also update the configs that referenced ubifsmount.

Using ZLIB compression with UBIFS fails if last data node is not a size of
UBIFS_BLOCK_SIZE (4096 bytes).
Easiest way to test this is trying to read a file smaller than 4k:

Loading file '/etc/fstab' to addr 0x41000000 with size 704 (0x000002c0)...

This patch fixes an issue when ubifs reads a bad superblock. Later it

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;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.
