This fixes the most obvious 64-bit problems, but it is still very very
broken in other aspects. It is bad enough that I feel irresponsible
turning it on in the 64-bit build.
For example, it takes an ioremap()'d value, and accesses it as a
regular cpu pointer which will explode on many architectures since
all such accesses should go through asm/io.h accessors.
Specifically I'm talking about dev->seg_ram, it is initialized like
this:
base = ioremap(real_base,iadev->pci_map_size); /* ioremap is not resolved ??? */
...
iadev->seg_ram = base + ACTUAL_SEG_RAM_BASE;
...
Then used like this:
desc1 = *(u_short *)(dev->seg_ram + dev->host_tcq_wr);
and this:
*(u_short *) (dev->seg_ram + dev->host_tcq_wr) = 0;
and this:
*(u_short *)(dev->seg_ram + dev->ffL.tcq_rd) = i+1;
and this:
desc_num = *(u_short *)(dev->seg_ram + dev->ffL.tcq_rd);
and this:
desc_num = *(u_short *)(dev->seg_ram + dev->ffL.tcq_rd);
and this:
SchedTbl = (u16*)(dev->seg_ram+CBR_SCHED_TABLE*dev->memSize);
...
TstSchedTbl = (u16*)(SchedTbl+testSlot); //set index and read in value
...
memcpy((caddr_t)&cbrVC,(caddr_t)TstSchedTbl,sizeof(cbrVC));
...
memcpy((caddr_t)TstSchedTbl, (caddr_t)&vcIndex,sizeof(TstSchedTbl));
Really, this driver has a ton of unresolved portability problems.
