2 | * Device Tree file for the Linksys WRT1900AC (Mamba). | |

4 | * Note: this board is shipped with a new generation boot loader that | |
5 | * remaps internal registers at 0xf1000000. Therefore, if earlyprintk | |
6 | * is used, the CONFIG_DEBUG_MVEBU_UART0_ALTERNATE option should be | |
7 | * used. | |
