| 12 | Flash Layout |
| 13 | ============ |
| 14 | A typical layout of various images (including Linux and other firmware images) |
| 15 | is shown below considering a 32MB NOR flash device: |
| 16 | |
| 17 | ------------------------- |
| 18 | | linux | |
| 19 | ------------------------- ----> 0x0120_0000 |
| 20 | | Debug Server | |
| 21 | ------------------------- ----> 0x00C0_0000 |
| 22 | | AIOP SW | |
| 23 | ------------------------- ----> 0x0070_0000 |
| 24 | | MC FW | |
| 25 | ------------------------- ----> 0x006C_0000 |
| 26 | | MC Data Path Layout | |
| 27 | ------------------------- ----> 0x0020_0000 |
| 28 | | BootLoader | |
| 29 | ------------------------- ----> 0x0000_1000 |
| 30 | | PBI | |
| 31 | ------------------------- ----> 0x0000_0080 |
| 32 | | RCW | |

| 37 | Environment Variables |
| 38 | ===================== |
| 39 | mcboottimeout: MC boot timeout in milliseconds. If this variable is not defined |
| 40 | the value CONFIG_SYS_LS_MC_BOOT_TIMEOUT_MS will be assumed. |
| 41 | |
| 42 | mcmemsize: MC DRAM block size. If this variable is not defined, the value |
| 43 | CONFIG_SYS_LS_MC_DRAM_BLOCK_MIN_SIZE will be assumed. |
