Function parse_cbmem_ref

util/cbmem/devmem_drv.c:446–458

This is a work-around for a nasty problem introduced by initially having * pointer sized entries in the lb_cbmem_ref structures. This caused problems * on 64bit x86 systems because coreboot is 32bit on those systems. * When the problem was found, it was corrected, but there are a lot of * systems out there with a firmware that does not produce the right * lb_cbmem_ref structure. Hence we try

 * lb_cbmem_ref structure. Hence we try to autocorrect this issue here.
