Subject: [SERIAL] AMD Alchemy UART: claim memory range
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=85835f442e5bbf9d3b8f6e574751da8db77016d2;p=openwrt%2Fstaging%2Fblogic.git

[SERIAL] AMD Alchemy UART: claim memory range

I've noticed that the 8250/Au1x00 driver (drivers/serial/8250_au1x00.c)
doesn't claim UART memory ranges and uses wrong (KSEG1-based) UART
addresses instead of the physical ones.
