This is the minimal patch needed to get the bootloader prompt on VGA for PReP.--- 1.1/arch/ppc/boot/simple/misc-prep.c Mon Mar 1 17:34:28 2004 +++ edited/arch/ppc/boot/simple/misc-prep.c Fri Aug 6 17:21:00 2004@@ -89,6 +89,7 @@ } #if defined(CONFIG_VGA_CONSOLE) + serial_fixups(); vga_init((unsigned char *)0xC0000000); #endif /* CONFIG_VGA_CONSOLE */Of course that looks funny doesn't it? "serial_fixups()" just sets ISA_io, so should probably be called something else.
Curse you folks with a video display! :)
Also it's written in assembly in legacy.S (with matching chrpmap.S), which could easily become prepmap.c and chrpmap.c.
OK. So when I wrote all of this initially, there was, I could have sworn, a good reason for doing 'serial_fixups' as an asm routine, and not just a define or C func. But, I can't recall why now. So if you'd be so kind as to whip up, and test, a patch which switches us to defines, or a C func, whichever ends up being easier, I'd appreciate it. Thanks.
Even better ISA_io could have a #define that's used in misc.c and misc-prep.c...
and ns16550.c
But all of this would require more digging through makefiles and weak aliases than it's probably worth.
