Hello, Developers. Trying to add support of st16c554 quad uart in at91rm9200 based board. First, doing menuconfig... >From /drivers/serial/Konfig: config SERIAL_8250_EXAR_ST16C554 tristate "Support Exar ST16C554/554D Quad UART" depends on SERIAL_8250 != n && ISA && SERIAL_8250_MANY_PORTS ISA required, but isn't avaiable for at91 system type: Symbol: ISA [=n] Type : boolean Selected by: ARCH_EBSA110 [=n] && <choice> || ARCH_SA1100 [=n] && ... no AT91 Nevertheless, this message http://www.spinics.net/lists/arm-kernel/msg55077.html gives hope that it is possible. But how? If this device is not supporting, suggest me please, what better to use instead. Thanks.
