Commit 90fbee3e4051 ("cmd_fdt: Actually fix fdt command in sandbox")
changed the format(from hex address to unsigned long) in which "fdtaddr"
is saved . However do_fdt continues reads the "fdtaddr" assuming it to
be in hex format. This may lead to fdt being either loaded or attempted
to load at erroneous address generating fault if the address is out of
memory.
This patch changes back the format to hex while saving the "fdtaddr"
as it was done before.

much work than just enabling CAR, it cannot read the configuration
data from device tree at that time. Now we want to move it a little
bit later as part of init_sequence_f[] being called by board_init_f().
This way it looks and works better in the U-Boot initialization path.
Due to FSP's design, after calling FspInitEntry it will not return to
its caller, instead it jumps to a continuation function which is given
by bootloader with a new stack in system memory. The original stack in
the CAR is gone, but its content is perserved by FSP and described by
a bootloader temporary memory HOB. Technically we can recover anything
we had before in the previous stack, but that is way too complicated.
To make life much easier, in the FSP continuation routine we just
simply call fsp_init_done() and jump back to car_init_ret() to redo
the whole board_init_f() initialization, but this time with a non-zero
HOB list pointer saved in U-Boot's global data so that we can bypass

stm32f4: fix MAINTAINERS file
When "scripts/get_maintainer.pl" parses "board/.../MAINTAINERS",
it uses the line containing board name as delimiter.
Without this line, the script happily mixes the lines from current
board MAINTAINERS file with lines from another file.
Fix it by adding a reasonable board name.
Tested by comparing output of:
cat board/st/stm32f429-discovery/MAINTAINERS
./scripts/get_maintainer.pl -f board/st/stm32f429-discovery

siemens,am33x: adjust mtd partition
Use one mtd partition for rootfs and configuration by
means of ubi volumes and get rid of configuration partition.
We can use partition layout for both 256MB and 512MB flash.

ARM: beagle_x15: prevent DCAN1 _wait_target_disable failure in kernel
If board is booted with transitions happening on DCAN1 pins then
the following warning is seen in the kernel at boot when the
hwmod layer initializes.
"omap_hwmod: dcan1: _wait_target_disable failed"
This is because DCAN1 module's SWAKEUP mechanism is broken
and it fails to correctly turn OFF if it sees a transition on the
DCAN1 pins. Suggested workaround is to keep DCAN1 pins in safe mode
while enabling/disabling DCAN1 module.
The hwmod layer enables and disables all modules at boot
and we have no opportunity to put the DCAN1 pins in safe mode
at that point.
DCAN1 is not used by u-boot so it doesn't matter to it if these
pins are in safe mode. The kernel driver correctly configures
the right mode when DCAN1 is active.

Makefile:Add GCC flag -fno-delete-null-pointer-checks
-fdelete-null-pointer-checks flag controls global dataflow analyses and
eliminate useless checks for null pointers; It assume that if a pointer is
checked after it has already been dereferenced, it cannot be null.
This flag is enabled by default.
gcc v4.9 has more optimizations added to this option. Hence it is very
aggressive with GCC v4.9 series. Add -fno-delete-null-pointer-checks to
disable the optimization
