This allows you to interact with 360af282245SSimon Glass U-Boot. 361af282245SSimon Glass 362af282245SSimon Glass The operation of the console is controlled by the -t command-line 363af282245SSimon Glass flag. In raw mode, U-Boot sees all characters from the terminal 364af282245SSimon Glass before they are processed, including Ctrl-C. In cooked mode, Ctrl-C 365af282245SSimon Glass is processed by the terminal, and terminates U-Boot. Valid options 366af282245SSimon Glass are: 367af282245SSimon Glass 368af282245SSimon Glass -t raw-with-sigs Raw mode, Ctrl-C will terminate U-Boot 369af282245SSimon Glass -t raw Raw mode, Ctrl-C is processed by U-Boot 370af282245SSimon Glass -t cooked Cooked mode, Ctrl-C terminates 371af282245SSimon Glass 372ff247b7aSMasahiro Yamadaconfig UNIPHIER_SERIAL 373b6ef3a3fSMasahiro Yamada bool "Support for UniPhier on-chip UART" 3742ea65f3eSMasahiro Yamada depends on ARCH_UNIPHIER 37585dc2fe1SMasahiro Yamada default y 376ff247b7aSMasahiro Yamada help 377b6ef3a3fSMasahiro Yamada If you have a UniPhier based board and want to use the on-chip 378b6ef3a3fSMasahiro Yamada serial ports, say Y to this option.
