Define this variable to enable hw flow control in serial driver.
Current user of this option is drivers/serial/nsl16550.c driver
-- Console Interface:
- Depending on board, define exactly one serial port
- (CONFIG_8xx_CONS_SMC1 or CONFIG_8xx_CONS_SMC2),
- or switch off the serial console by defining
- CONFIG_8xx_CONS_NONE
-
- Note: if CONFIG_8xx_CONS_NONE is defined, the serial
- port routines must be defined elsewhere
- (i.e. serial_init(), serial_getc(), ...)
-
- Console Baudrate:
CONFIG_BAUDRATE - in bps
Select one of the baudrates listed in
CONFIG_SYS_BAUDRATE_TABLE, see below.
- CONFIG_SYS_BRGCLK_PRESCALE, baudrate prescale
-
-- Console Rx buffer length
- With CONFIG_SYS_SMC_RXBUFLEN it is possible to define
- the maximum receive buffer length for the SMC.
- This option is actual only for 8xx possible.
- If using CONFIG_SYS_SMC_RXBUFLEN also CONFIG_SYS_MAXIDLE
- must be defined, to setup the maximum idle timeout for
- the SMC.
- Autoboot Command:
CONFIG_BOOTCOMMAND
CONFIG_CMD_RUN run command in env variable
CONFIG_CMD_SANDBOX * sb command to access sandbox features
CONFIG_CMD_SAVES * save S record dump
- CONFIG_SCSI * SCSI Support
CONFIG_CMD_SDRAM * print SDRAM configuration information
(requires CONFIG_CMD_I2C)
CONFIG_CMD_SF * Read/write/erase SPI NOR flash
Default is 32bit.
- SCSI Support:
- At the moment only there is only support for the
- SYM53C8XX SCSI controller; define
- CONFIG_SCSI_SYM53C8XX to enable it.
-
CONFIG_SYS_SCSI_MAX_LUN [8], CONFIG_SYS_SCSI_MAX_SCSI_ID [7] and
CONFIG_SYS_SCSI_MAX_DEVICE [CONFIG_SYS_SCSI_MAX_SCSI_ID *
CONFIG_SYS_SCSI_MAX_LUN] can be adjusted to define the
maximum numbers of LUNs, SCSI ID's and target
devices.
- CONFIG_SYS_SCSI_SYM53C8XX_CCF to fix clock timing (80Mhz)
The environment variable 'scsidevs' is set to the number of
SCSI devices found during the last scan.
