RE: [microblaze-uclinux] Adding kernel support for more UARTs

["Douglas Bruey" <dougb@xxxxxxxx>]

Thanks John. That worked wonderfully.

The only other thing I did was add the additional device nodes to the romfs
by following the instructions in the Petalinux User Guide.

Thanks again,
Doug

Line 23 of drivers/serial/uartlite.c, ULITE_NR_UARTS

If you go to more than 6 devices you will also need to add more entries 
in the xilinx_uartlite_device[] table around line 45 of

/arch/microblaze/platform/common/xuartlite.c
