[PATCH] Convert Geode GX2 boards to CAR
by Nils 28 Jun '10

28 Jun '10

This patch converts the Geode GX2 boards to CAR. It reduces the boot time with ~35 seconds in "Stage: loading fallback/coreboot_ram". After the conversion GCC gave a lot of build warnings in the old ROMCC code (especially in the southbridge CS5535 code used by the Lippert Frontrunner board) which i had to fix. It is ABUILD tested and boot tested on my Wyse S50. Signed-off-by: Nils Jacobs <njacobs8(a)hetnet.nl> Patch and bootlog attached. I hope someone will find some time to review this rather large patch. Thanks,Nils.

[PATCH]Build mptable bus entries from device tree
by Patrick Georgi 25 Jun '10

25 Jun '10

Hi, attached patch adds code to create bus entries in the mptable from the device tree instead of the hardcodes we do right now. It also changes kontron/986lcd-m to use the new function, where its advantage is starting to show: As we support a given riser card (with pci bridge and bus), we currently have to look for the card and add a bus and interrupt sources to the mptable. With this patch, the bus is automatically added to the table. Once interrupt sources are handled the same way, that special case could be dropped completely (and such plug-in cards that add buses will be properly supported on all boards) I didn't adapt all the mptable.c files in the tree, as I feel the code should be tested on a more diverse set of boards. Our table generation code sometimes differs only so slightly, and I don't know in all cases if the automatic handling would pick up those differences, or if they actually matter (or are correct in the first place).

How to change the device id of a VBIOS
by Bao, Zheng 25 Jun '10

25 Jun '10

Some of the VGA modules have almost same function and vgabios. The only difference is the Device ID. I am wondering, if I got a Vgabios for graphics card A, can I just change the device ID in the binary file to fit the graphics B? Is there any checksum in the vgabios.bin? Is there a tool to handle it? Zheng

AMD740G - Not supported yet?

I noticed that there is still a request for AMD740G chipset info almost a year later after I first posted some info regarding it. Is it in limbo now? Cheers, Gary

I have a couple of questions: - Can we have the option disappear in Kconfig without having to define USE_OPTION_TABLE with an #ifdef? I'd like it if that could stay in Kconfig. - Why is the prototype for read_option conditionally defined when the function is always defined? - Why is read_option inline? - How does an inlined function get called when it's compiled into an initobj? Thanks, Myles

An error when compiling FILO because of IS_PC_SLICE_TYPE_BSD
by Jiang Wang 24 Jun '10

24 Jun '10

Hi, I just found an error when compiling FILO. I used "svn co" to get the current coreboot and FILO source code ,and followed this link to compile FILO: http://www.coreboot.org/FILO However, I got an error saying "/main/grub/completions.c:204: undefined reference to IS_PC_SLICE_TYPE_BSD". After some search and help from linux_junkie from IRC, we found out that this IS_PC_SLICE_TYPE_BSD is not defined. My current hack is to copy "./fs/filesys.h:265:#define IS_PC_SLICE_TYPE_BSD_WITH_FS(type,fs) 0" to the completions.c file, and modified the line 204 to use this macro as following: && ! IS_PC_SLICE_TYPE_BSD_WITH_FS(current_slice, 0)) { Then it compiles well. Hope this information is helpful. BTW: I tried to include filesys.h directly but got lots of compiling errors. Regards, Jiang
