building lilo, grub or PPCBoot for a custom board

Hi !

I' succedded in building denx-eldk from rpm packages on my RedHat 8.0 (thanks wolfgang !), and then a 1st linux kernel that I'd like to download via the VME into the FLash ROM.

So I'm trying to build a cute boot loader (for linux of course !) for my custom board :

- VME64x based
- PCC755 without L2 cache
- no PCI bus
- 2Mo Flash 29DL163 at 0xFFE00000
- 128 Mo SDRAM at 0x0000000
- a simple UART
- some analog I/Os

the UART, VME and Flash drivers source code is ok, but I still have somme questions :

- where and how to introduce the arch dependent source code in the source
tree of those boot loaders ?
- how to configure the Makefile to build a light exe ?
- how to configure the linker command file or ld swithes for a particular
mapping ?

Thanks,

Regards, JC.
