8260ADS Ethernet compilation

[pritha.bhattacharya at tcs.com]

Hi,

I have a custom board built around MPC8260ADS. I am trying to cross 
compile linux 2.4.25 for ethernet on FCC1 connected to LXT971 for the 
board. 
Installed the toolchains from Denx site. Built linux for ppc architecture. 
Then for ethernet, after selecting the proper options from the menuconfig, 
while compiling the source code gives the following error:

m8260_setup.c:62: error: `bd_t' undeclared here (not in a function)

1.I understand that bd_t is a board information structure. Which is 
defined in linux/include/asm-ppc/ppcboot.h. Somehow it is not visible to 
the linux/arch/kernel/m8260_setup.c  I dont know what I may be doing 
wrong.

2.Similarly NR_SIU_INTS, which is defined in linux/include/asm/irq.h is 
also not visible.

the third query is not on compilation errors:
3.I did not understand what __res[ ] is. I came across somewhere that it 
is the residual information which the bootloader is supposed to hand over 
to the linux. How would that be done. I could not identify in the code 
where __res is populated. 

Would be of great help to get your suggestions.


Thanks & Regards
Pritha
