Re: [microblaze-uclinux] EthernetLite driver

["Pavel Ivanchenko" <pi-home@xxxxxxx>]

Hello, John.
Thanks for you work!
I apply patch and it create 
uClinux-dist/linux-2.4.x/drivers/net/xilinx_emaclite/ directory with files 
and string in the menuconfig, but make no have effect with driver sources. I 
try include driver as module and integrate to kernel, after make, image size 
exactly coincides.
I try add next strings to uClinux-dist/linux-2.4.x/drivers/net/Makefile:
mod-subdirs     += xilinx_emaclite
subdir-$(CONFIG_XILINX_EMACLITE) += xilinx_emaclite
obj-$(CONFIG_XILINX_EMACLITE) += xilinx_emaclite/xilinx_emaclite.o

After "make dep" there was is created ".depend" file in /xilinx_emaclite/, 
but make unsuccessful. Last screen with error include.
