help
This will try to automatically determine if the current tree is a
release tree by looking for git tags that belong to the current
top of tree revision.
A string of the format -gxxxxxxxx will be added to the localversion
if a git-based tree is found. The string generated by this will be
appended after any matching localversion* files, and after the value
set in CONFIG_LOCALVERSION.
(The actual string used here is the first eight characters produced
by running the command:
$ git rev-parse --verify HEAD
which is done within the script "scripts/setlocalversion".)

support is quite experimental at the moment. There is no convenient
way to compile modules and the list of exported symbols to actually
make use of modules is short to nonexistent

With Kallsyms enabled all symbols are compiled into the barebox image.
This is useful to print a nice backtrace when an exception occurs.
config RELOCATABLE

bool "generate relocatable barebox binary"
help
A non relocatable barebox binary will run at it's compiled in
link address in RAM. This leads to smaller image sizes but may
put barebox just in the middle of RAM. With this option enabled
instead barebox can determine this address at runtime and thus
allowing it to relocate to the end of the available RAM. This
way you have the whole memory in a single piece.

bool "generic polling infrastructure"
config ANTIREBOOTLOOP
bool "Anti reboot loop feature"
help
The anti reboot loop feature is a communication protocol between the
bootloader and the kernel that allows the bootloader to determine if a
certain kernel/rootfs image is "good". The way it works is that the
bootloader writes a certain bit pattern to a previously agreed memory
location. If a userspace app decides that the kernel has booted ok and
that the user space environment is sane, it tells the kernel which then
flips a bit in DRAM to communicate to the bootloader that this image is
considered "good". Now, if the system reboots due to some failure
condition before said bit has been flipped, the bootloader is able to
detect this situation and switch back to a different kernel/rootfs
image.
