Hi,
please find in attachment an ARMv7 -default config update to fix Ethernet and HDMI output on iMX6 SABRE Lite board. It also add initial support to USB on this board.
This patch is against master branch.
Signed-off-by: Guillaume GARDET <guillaume.gardet@opensuse.org> Moving modules from =m to =y is the wrong answer usually. Why don't the modules work as modules? I do not know. Modules are loaded with no error but they do not work. The fact is switching FEC and SDMA from =m to =y fix the problems. It is true for 13.1 and master branches.
Yes, I've spent some time myself to fix FEC as a module on i.MX53 a while ago. We really don't want to even start going into the game of enabling random devices as =y on the default config, otherwise we'll end up with a 30MB kernel on all boards.
I agree, but the fact is we have no board which works really fine ATM. See: http://en.opensuse.org/openSUSE:Supported_ARM_boards#13.1 There are only RPi and Chromebook which have a correct support (and they use _downstream_ kernels). But chromebook boot only once and need a hack to boot then (I am on it, Marcus gave me some hints to fix that using kiwi hooks) and had a lot of X stability problems (random freezes, X crash when switching VT). Raspberry Pi is not booting at all as is (kiwi partitioning bug) and need a hack to get a bootable image: http://en.opensuse.org/HCL:Raspberry_Pi#Known_Issues Maybe Beaglebone or Beaglebone black have a good support? (I do not have such devices and there is no feedback on our wiki) Now, SABRE Lite is the only board where I got graphics working with upstream kernel. The last blocking problem on this board is USB which is not working, even with imx_v6_v7_defconfig. The main things to do for boards support are : 1) Get boards booting Linux (should be a minimum). 2) Have a maximum number of supported devices (USB, sound, video, etc.) on each board (even if it does mean to have '=y' instead of '=m'). 3) Clean-up / fix our kernel / kernel configs to use modules (=m) instead of built-in (=y) when it is possible. I think we should use again our Trello board or setup a wiki page or something to write down what must be done for each board and who is taking care of each task. What do you think about that?
