Subject: [MIPS] Cobalt: Qube1 has no serial port so don't use it
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c43756da94863395d5ee088659676029b3ae7191;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

[MIPS] Cobalt: Qube1 has no serial port so don't use it

Because Qube1 doesn't have a serial chip waiting for transmit fifo empty
takes forever, which isn't a good idea. No prom_putchar/early console
for Qube1 fixes this.
