config SERIAL_SH_SCI_NR_UARTS
int "Maximum number of SCI(F) serial ports" if EXPERT
depends on SERIAL_SH_SCI
default "3" if H8300
default "10" if SUPERH
default "18" if ARCH_RENESAS
Doh, if test compiling for non-H8300/SUPERH/ARCH_RENESAS, "int" doesn't
assign a sane numerical default value to the symbol, but an empty string :-(
So we do need e.g.
default "2"
at the bottom.
Greg: Do you want a v2, or an incremental patch?
Thanks, and sorry for missing this.
