dm: core: Add dev_get_addr_ptr() to return a pointer to the reg address
On some platforms (e.g. x86), the return value of dev_get_addr() can't
be assigned to a pointer type variable directly. As there might be a
difference between the size of fdt_addr_t and the pointer type. On
x86 for example, "fdt_addr_t" is 64bit but "void *" only 32bit. So
assigning the register base directly in dev_get_addr() results in this
compilation warning:
warning: cast to pointer from integer of different size
This patch introduces the new function dev_get_addr_ptr() that
returns a pointer to the 'reg' address that can be used by drivers
in this case.

ubifs: fix memory corruption in super.c
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

Due to incorrect placement of the clock gate cell in the ldb_di[x]_clk tree,
the glitchy parent mux of ldb_di[x]_clk can cause a glitch to enter the
ldb_di_ipu_div divider. If the divider gets locked up, no ldb_di[x]_clk is
generated, and the LVDS display will hang when the ipu_di_clk is sourced from
ldb_di_clk.
To fix the problem, both the new and current parent of the ldb_di_clk should
be disabled before the switch. This patch ensures that correct steps are
followed when ldb_di_clk parent is switched in the beginning of boot.
This patch was ported from the 3.10.17 NXP kernel

arm: mx5: Fix NAND image generation
The echo -ne "\xNN" does not work in certain bourne-compatible shells, like
dash. The recommended way of hex->char conversion is using printf(1), but
there is a pitfall here. The GNU printf does support "\xNN" format, but
according to the opengroup documentation, this is not part of POSIX. The
POSIX printf only defines "\NNN" where N is octal. Thus, for the sake of
compatibility, we use that.
