[flashrom] Large FWH support

Sat Feb 23 22:06:31 CET 2013

Hi

I came across two problems using 2 MiB FWH flash on two different boards
with old ICH4 and ICH6 chipsets:

First, ICH3/4/5 do not implement fwh_idsel= parameter. If vendor bios
had the default map of 1 MiB, it did not even detect 2 MiB flash chips.
For this I have patches prepared already.

Before: (idsel_failure.txt)
Probing for SST SST49LF008C, 1024 kB: probe_82802ab: id1 0xbf, id2 0x5c
Probing for SST SST49LF016C, 2048 kB: probe_82802ab: id1 0xff, id2 0xff, id1 parity violation, id1 is normal flash content, id2 is normal flash content

After: (idsel_ok.txt)
Probing for SST SST49LF008C, 1024 kB: probe_82802ab: id1 0xbf, id2 0x5c
Probing for SST SST49LF016C, 2048 kB: probe_82802ab: id1 0xbf, id2 0x5c
Found SST flash chip "SST49LF016C" (2048 kB, FWH) at physical address 0xffe00000.

Second, a board with ICH6 had all except one 512 kiB range of flash
disabled by vendor bios and it would not detect 1MiB and 2MiB flash
chips. NOTE: the board actually had 512kiB flash for these logs, but you
can see where ther problem is.

Before: (decode-disabled.txt)
0xfff80000/0xffb80000 FWH decode enabled
0xfff00000/0xffb00000 FWH decode disabled
0xffe80000/0xffa80000 FWH decode disabled
0xffe00000/0xffa00000 FWH decode disabled
...
Maximum FWH chip size: 0x80000 bytes
...
Probing for SST SST49LF008C, 1024 kB: Chip size 1024 kB is bigger than supported size 512 kB of chipset/board/programmer for FWH interface, probe/read/erase/write may fail. probe_82802ab: id1 0xff, id2 0xff, id1 parity violation, id1 is normal flash content, id2 is normal flash content

I used the following as a work-around for ICH6, but this should be
derived from fwh_idsel= parameter:
  $ setpci -s 0:1f.0 0xd8.W=0xf0c0

After: (decode-enabled.txt)
0xfff80000/0xffb80000 FWH decode enabled
0xfff00000/0xffb00000 FWH decode enabled
0xffe80000/0xffa80000 FWH decode enabled
0xffe00000/0xffa00000 FWH decode enabled
