* floating pointer length + maximum length of configuration table
* ACRN uses contiguous guest memory from 0xF0000 to place floating pointer
* structure and config table. Maximum length of config table is 64K. So the
* maximum length of combined floating pointer and config table can go up to
* 64K + 16 bytes.Since we are left with only 64K from 0xF0000 to 0x100000(1MB)
* max length is limited to 64K.
