+         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
