Dear wolfgang denk,
please review and let me know if this is right way of posting. 
thanks for both the links. yeah sorry about top posting full quote . Now im
trying to follow those rules in the links which u have given to me.

l>ike, which commands you used, or what the error messages might have

Now im writing in detail what im trying to do. all i want to do is compile
the file in /drivers/spi/atmel_spi.c which is nothin  but initialize the SPI
controller in u-boot for my board AT91SAM9261.  so i added the lines
#define CONFIG_ATMEL_SPI 1
#define CONFIG_CMD_SPI 1
 in my config file which is located at  /include/configs/at91sam9261ek.h
but as i said i got a error  which im posting below . may i know what is
going wrong?  thanks for those links again. 
this is error i got when i was compiling uboot.

make -C drivers/spi/
make[1]: Entering directory
`/home/ravikulkarni/dasuboot_airforce/u-boot-1.3.4/drivers/spi'
/opt/timesys/toolchains/armv5l-linux/bin/armv5l-linux-gcc -g  -Os

atmel_spi.c: In function `spi_setup_slave':
atmel_spi.c:51: error: `SPI0_BASE' undeclared (first use in this function)
atmel_spi.c:51: error: (Each undeclared identifier is reported only once
atmel_spi.c:51: error: for each function it appears in.)
atmel_spi.c:73: warning: implicit declaration of function `get_spi_clk_rate'
make[1]: *** [atmel_spi.o] Error 1
make[1]: Leaving directory
`/home/ravikulkarni/dasuboot_airforce/u-boot-1.3.4/drivers/spi'
make: *** [drivers/spi/libspi.a] Error 2

 I'm thinking  we have to  write an init function in the  file
/board/atmel/at91sam9261ek/at91sam9261ek.c defining which pins and all? am i
right?

warm regards,
Ravi Kulkarni.
