  91 Environment Variables
  92 =====================
  93 mcboottimeout:  MC boot timeout in milliseconds. If this variable is not defined
  94                 the value CONFIG_SYS_LS_MC_BOOT_TIMEOUT_MS will be assumed.
  95
  96 mcmemsize:      MC DRAM block size. If this variable is not defined, the value
  97                 CONFIG_SYS_LS_MC_DRAM_BLOCK_MIN_SIZE will be assumed.
