XUP Virtex II p with Linux 2.4 - Question

[rodolfo]

Hi everybody!

I subscribe on this list today because i have some problems with linux
kernel 2.4 compilation. I'm using EDK/ISE 9.1i, crosstool-0.38 . I follow
this sites:

- http://www.cs.washington.edu/research/lis/empart/xup_ppc_linux.shtml
- http://splish.ee.byu.edu/projects/LinuxFPGA/
- http://www.crhc.uiuc.edu/IMPACT/gsrc/hardwarelab/docs/kernel-HOWTO.html

I have a lot of error like this: "can not found ...", "undeclared first in
this function...". But i could solve them! Now the problem is:

../common/ns16550.c: In function `serial_init':
../common/ns16550.c:63: error: `XPAR_UARTNS550_0_CLOCK_FREQ_HZ' undeclared
(first use in this function)
../common/ns16550.c:63: error: (Each undeclared identifier is reported only
once
../common/ns16550.c:63: error: for each function it appears in.)
make[2]: ** [../common/ns16550.o] Erro 1
make[2]: Saindo do diretório
`/home/rodolfo/Desktop/Projeto_Linux_Embedded/bk-client2.0/linux/arch/ppc/boot/simple'
make[1]: ** [zImage.initrd] Erro 2
make[1]: Saindo do diretório
`/home/rodolfo/Desktop/Projeto_Linux_Embedded/bk-client2.0/linux/arch/ppc/boot'

Anybody can help me? i'm new in this world (fpga - linux)!
