This format will support execution of NuttX binaries located

Binary Loaders:
CONFIG_BINFMT_DISABLE - By default, support for loadable binary formats
is built.
This logic may be suppressed be defining this setting.
CONFIG_BINFMT_CONSTRUCTORS - Build in support for C++ constructors in
loaded modules.
CONFIG_SYMTAB_ORDEREDBYNAME - Symbol tables are order by name (rather
than value).
CONFIG_NXFLAT. Enable support for the NXFLAT binary format. This format
will support execution of NuttX binaries located in a ROMFS filesystem
(see examples/nxflat).
CONFIG_ELF - Enable support for the ELF binary format. This format will
support execution of ELF binaries copied from a file system and
relocated into RAM.
If CONFIG_ELF is selected, then these additional options are available:
CONFIG_ELF_ALIGN_LOG2 - Align all sections to this Log2 value: 0->1,
1->2, 2->4, etc.
CONFIG_ELF_STACKSIZE - This is the default stack size that will will
be used when starting ELF binaries.
CONFIG_ELF_BUFFERSIZE - This is an I/O buffer that is used to access
the ELF file. Variable length items will need to be read (such as
symbol names). This is really just this initial size of the buffer;
it will be reallocated as necessary to hold large symbol names).
Default: 128
CONFIG_ELF_BUFFERINCR - This is an I/O buffer that is used to access
the ELF file. Variable length items will need to be read (such as
symbol names). This value specifies the size increment to use each
time the buffer is reallocated. Default: 32
CONFIG_ELF_DUMPBUFFER - Dump various ELF buffers for debug purposes.
This option requires CONFIG_DEBUG and CONFIG_DEBUG_VERBOSE.
System Logging:
CONFIG_SYSLOG enables general system logging support.
CONFIG_SYSLOG_DEVPATH - The full path to the system logging device. Default
