Mistery of the function: static void enable_rom_caching(void)
by Zoran Stojsavljevic 08 Aug '16

08 Aug '16

Hello community, I was/got again today in Coreboot directory src/soc/intel/braswell/bootblock/bootblock.c looking at static void enable_rom_caching(void). Then, since Paul Menzel have announcement ([ANNOUNCEMENT] Support for Intel Kaby Lake), I went to look into src/soc/intel/skylake/bootblock/bootblock.c, but I did not find this function. Kaby Lake patches do not support this function as well. Then I did the following on my WIN 10 (using VMware workstation 12) VM Fedora 24: [zoran@localhost intel]$ pwd /home/zoran/projects/coreboot/coreboot/src/soc/intel [zoran@localhost intel]$ git describe 4.4-1038-gdd65ef8 [zoran@localhost intel]$ ls -al total 48 drwxrwxr-x. 12 4096 Aug 1 10:02 . drwxrwxr-x. 14 4096 Aug 1 10:02 .. drwxrwxr-x. 5 4096 Aug 1 10:02 apollolake drwxrwxr-x. 6 4096 Aug 1 10:02 baytrail drwxrwxr-x. 6 4096 Aug 1 10:02 braswell drwxrwxr-x. 6 4096 Aug 1 10:02 broadwell drwxrwxr-x. 3 4096 Aug 1 10:02 common drwxrwxr-x. 7 4096 Aug 1 10:02 fsp_baytrail drwxrwxr-x. 7 4096 Aug 1 10:02 fsp_broadwell_de drwxrwxr-x. 5 4096 Aug 1 10:02 quark drwxrwxr-x. 3 4096 Aug 1 10:02 sch drwxrwxr-x. 7 4096 Aug 1 10:02 skylake [zoran@localhost intel]$ grep -r enable_rom * baytrail/bootblock/bootblock.c:static void enable_rom_caching(void) baytrail/bootblock/bootblock.c: enable_rom_caching(); braswell/bootblock/bootblock.c:static void enable_rom_caching(void) braswell/bootblock/bootblock.c: enable_rom_caching(); broadwell/bootblock/cpu.c:static void enable_rom_caching(void) broadwell/bootblock/cpu.c: enable_rom_caching(); fsp_baytrail/bootblock/bootblock.c:static void enable_rom_caching(void) fsp_baytrail/bootblock/bootblock.c: enable_rom_caching(); [zoran@localhost intel]$ We see here that from skylake (also does not exists in apollolake) this function is dropped. Any logical explanation for this mismatch? Thank you, Zoran

How to add Medion AKOYA S2013 (google/veyron_jaq)
by Paul Menzel 08 Aug '16

08 Aug '16

Dear coreboot folks, I got the Rockchip RK3288 based Google Chromebook Medion AKOYA S2013 which is or is based on the google/veyron_jaq board. In the tree, there is currently the Haier Chromebook 11, also based on `google/veyron_jaq`. `src/mainboard/google/veyron/Kconfig.name` contains: 5 config BOARD_GOOGLE_VEYRON_JAQ 6 bool "Haier Chromebook 11 (Veyron_Jaq)" 7 select BOARD_GOOGLE_VEYRON 8 select SYSTEM_TYPE_LAPTOP How can the Medion AKOYA S2013 be added, so that it is available in the list? Just add it to the description as it’s the same board? Thanks, Paul

Re: [coreboot] Strange postcodes

@Zoran: You are right. I just didn't know where those codes mean. After adding VGA BIOS i got to see the result. @Patrick: Seems that I haven't searched well enough. Sorry for the noise. In the thread Zoran pointed me to there was a nice idea to redirect normal postcodes to different address or disable them. If something else was writting postcodes then i would be easy to confirm that. Thanks You for Your help Zoran, Patrick!

[ANNOUNCEMENT] Support for Intel Kaby Lake
by Paul Menzel 07 Aug '16

07 Aug '16

Dear coreboot folks, Intel has started to submit change sets adding support for the new chipset Intel Kaby Lake [1]. > Kaby Lake is Intel's codename for the upcoming 14 nanometer successor > to the Skylake microarchitecture. Kaby Lake began shipping to > manufacturers and OEMs in the second quarter of 2016, though volume > production for the retail channel is anticipated late-2016. > > Skylake was to be succeeded by the 10 nanometer Cannonlake, but it > was announced on July 16, 2015, that Cannonlake has been delayed > until the second half of 2017. As it’s very similar to Intel Skylake, the goal is to adapt the Intel Skylake code, so that it supports both chipsets.

07 Aug '16

Dear coreboot folks, this is just a notification, that the development boards google/rush [1] and google/rush_ruy [2] using the NVIDIA Tegra T132 chipset are going to be removed, as these development boards are not available anymore, and never made it into a product. The chipset code is also removed, as there are no users left [3]. Thanks, Paul [1] https://review.coreboot.org/16106 [2] https://review.coreboot.org/16107 [3] https://review.coreboot.org/16108

Re: [coreboot] ARM Trusted Firmware build issue

Hey, Le mercredi 03 août 2016 à 09:18 -0600, Martin Roth a écrit : > I'll get that patch tested and replace the current patch with it if it > works. I just did over the week-end (building elm, but obviously couldn't test on the device) and the patch proposed by upstream solves the issue as well. It was merged in binutils in the meantime: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=7ea12e5c3ad54da4… I'll update the patch we have in crossgcc ASAP.
