Keith Hui e089a3f68d northbridge/intel/i440bx: Registered SDRAM modules support and fixes 
Adds support for initializing registered SDRAM modules on
Intel 440BX northbridge.

Drops unneeded romcc-inspired programming tricks.

Only set nbxecc flags (see 440BX datasheet, page 3-16) when
a non-ECC module has been detected in a row via SPD; also
drops an unneeded intermediate variable used in setting them.

Boot tested on ASUS P2B-LS with regular and registered ECC
SDRAM under Linux and memtest86+.

i440lx We hardcode highmemory size in every northbridge! This is bad, and especially if suspend to ram is involved. Let the default be taken from cbmem.h which also handles the suspend logic. 2010-12-13 19:50:25 +00:00
