+- CONFIG_ARCH_MAP_SYSMEM
+               Generally U-Boot (and in particular the md command) uses
+               effective address. It is therefore not necessary to regard
+               U-Boot address as virtual addresses that need to be translated
+               to physical addresses. However, sandbox requires this, since
+               it maintains its own little RAM buffer which contains all
+               addressable memory. This option causes some memory accesses
+               to be mapped through map_sysmem() / unmap_sysmem().

 - CONFIG_USE_ARCH_MEMCPY
   CONFIG_USE_ARCH_MEMSET
                If these options are used a optimized version of memcpy/memset will
                be used if available. These functions may be faster under some
                conditions but may increase the binary size.
 
-- CONFIG_X86_NO_RESET_VECTOR
-               If defined, the x86 reset vector code is excluded. You will need

-- CONFIG_X86_NO_REAL_MODE
-               If defined, x86 real mode code is omitted. This assumes a
-               32-bit environment where such code is not needed. You will
-               need to do this when U-Boot is running from Coreboot.
