Dear coreboot and flashrom folks,
Carl-Daniel asked me on IRC to relay the following information to you list subscribers.
In summary Carl-Daniel is trying to get the HP 635 laptop supported by flashrom and to port coreboot to it. In this message you will find the information/data/specifications [1] Carl-Daniel found out until now attached and the URL of the file in flashrom’s file upload service.
The HP 635 is a laptop with a AMD E-350 CPU and costs inclusive shipping 269 € (price comparison: [2]).
flashrom runs on the system but does not find a chip [3].
Found chipset "AMD SB700/SB710/SB750/SB850" with PCI ID 1002:439d Super I/O ID 0x8518 is not on the list of flash capable controllers
“This means we not only have a really well-supported chipset (AMD RS880M/A50M) the EC in that laptop ITE IT8518 is well-documented as well. I have the IT8512 docs and they are quite extensive. Does anyone have ITE IT8518 docs?”
“Ah yes, indeed an ITE EC: The BIOS image contains "EC-V11 Copyright ITE Tech. Inc.. This also means we can ask ITE nicely for distribution rights without worrying about some closed bios vendor having a copyright on that EC image.”
Output of `lspci` [4] and of `superiotool` [5] are also available.
The forced dump of the BIOS image [6] has a size of 2 MB and probably contains some garbage. The access is restricted to a few though. The executable of the BIOS upgrade file [7, probably different version] can be extracted using `cabextract` [8].
Uwe noted the following.
SCH5317 is LPC, so unlikely to be the match, yes. SMSC _does_ have some ECs though IIRC
Carl-Daniel will probably not have any Internet access during the next two weeks. But I guess when getting back he would be delighted if he receives some answer from other interested people porting the HP 635 and he could get the documentation of the EC he asked for.
I do not know if he starts hacking and for example already works on the flashrom support. Please join the channels #flashrom or #coreboot to get a hold of him and discuss these issues with Carl-Daniel and the rest of the coreboot/flashrom folks.
Thanks,
Paul
PS: Stefan, Uwe, I hope this message is what Carl-Daniel expected. If not please correct my mistakes.
