Hi Wolfgang,

I have been playing around with gcc's -fpic and ld's -PIE and I think that I can get 'proper' relocation happening on the i386 port. I've get the basics down, and I've been looking at /lib_ppc/board.c for how the PPC relocation scheme works and would like to replicate it (i.e. board_init_f, board_init_r and relocate_code.

Unfortunately this leaves two options:

1. Tangle the i386 port up in a heap of #ifdefs, or;
2. Do a clean re-write for the eNET and break the other i386 boards

(sc520_cdp and sc520_spunk).

Actually, I have a 3rd (better) plan - I'll create new source files for the relocatable version and conditionally compile based on a new #define in the board header.

Looking forward to getting into it :)

The other two i386 boards are OLD and i have my doubts as to if they ever did work completely, and have really strong doubts as to them working now

I would really like to just throw all the old code out and do it all cleanly, but not without strong support from the community.

What are your thoughts?

Regards,

G
