config LOCALVERSION
string "Local version - append to U-Boot release"
help
Append an extra string to the end of your U-Boot version.
This will show up in your boot log, for example.
The string you set here will be appended after the contents of
any files with a filename matching localversion* in your
object and source tree, in that order. Your total string can
be a maximum of 64 characters.
config LOCALVERSION_AUTO
bool "Automatically append version information to the version string"
default y
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".)

Enabling this option will make U-Boot be run as a bootloader

Xen is a virtual machine monitor (VMM) or a type-1 hypervisor with support
for para-virtualization. Xen can organize the safe execution of several
virtual machines on the same physical system with performance close to
native. It is used as the basis for a number of different commercial and
open source applications, such as: server virtualization, Infrastructure
as a Service (IaaS), desktop virtualization, security applications,
embedded and hardware appliances.
Xen has a special VM called Domain-0 that runs the Dom0 kernel and allows
Xen to use the device drivers for the Domain-0 kernel by default.

config SYS_MALLOC_CLEAR_ON_INIT
bool "Init with zeros the memory reserved for malloc (slow)"
default y
help
This setting is enabled by default. The reserved malloc
memory is initialized with zeros, so first malloc calls
will return the pointer to the zeroed memory. But this
slows the boot time.
It is recommended to disable it, when CONFIG_SYS_MALLOC_LEN
value, has more than few MiB, e.g. when uses bzip2 or bmp logo.
Then the boot time can be significantly reduced.
Warning:
When disabling this, please check if malloc calls, maybe
should be replaced by calloc - if one expects zeroed memory.
config SYS_MALLOC_DEFAULT_TO_INIT
bool "Default malloc to init while reserving the memory for it"

help
It may happen that one needs to move the dynamic allocation
from one to another memory range, eg. when moving the malloc
from the limited static to a potentially large dynamic (DDR)
memory.
If so then on top of setting the updated memory aside one
needs to bring the malloc init.
If such a scenario is sought choose yes.

Normally when linking U-Boot we will look in the board directory,
the CPU directory and finally the "cpu" directory of the architecture
for the ile "u-boot.lds" and use that as our linker. However, in
some cases we need to provide a different linker script. To do so,
enable this option and then provide the location under

Some U-Boot pointers have redundant information, so we can use a
scheme where we can return either an error code or a pointer with the
same return value. The default implementation just casts the pointer
to a number, however, this may fail on platforms where the end of the
address range is used for valid pointers (e.g. 0xffffff00 is a valid
heap pointer in socfpga SPL).
For such platforms, this value provides an upper range of those error
pointer values - up to 'MAX_ERRNO' bytes below this value must be
unused/invalid addresses.
