| 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. |
