[PATCH] S5PC2XX: Rename S5pc2XX to exynos4

by Chander Kashyap

As per new conventions Samsung SoC's are named as Exynos. Cortex-A9 based Soc's are named as exynos4. s5pc2xx is cortex-A9 based, hence renamed to exynos4. This is done as per kernel naming convetions. Similerly rename the s5p-common to exynos-common and libs5p-common to libexynos-common.

linaro-unified-tracking

by Andy Green

Hi - Thanks to the work of Angus and Tushar a second Landing Team has established a tracking tree, for Samsung Origen. They're using the same lt-tools management scripts I use to handle the various trees in TI Landing Team. As I mentioned in the talk I gave at Connect about lt-tools, the fact that we're both tracking near Linus HEAD allows us to casually combine the trees for the first time if we can arrange for our basis to be relatively close. Today with the help of Angus and Tushar I gave that a try and --> http://git.linaro.org/gitweb?p=landing-teams/working/ti/kernel.git;a=shortl… this single tree builds current Landing Team tracking for both Panda (omap4_defconfig) and Origen (origen_defconfig), we confirmed the results work as expected. Its common basis is Linus HEAD from yesterday. Actually, the two trees did not tread on each others' toes at all, the rebase proceeded with zero conflicts. Angus mentioned that there are still some topics to come on his side; maybe they can create conflicts in the future. Panda tracking got battered by upstream stuff post-3.1 we're still working to clear but it's still workable for this test purpose anyway since it includes all the code footprint. So we should be able to make ongoing combined tracking releases, and if that continues to work smoothly it will naturally lead to a combined 3.2 release tree. Since we'll both be using the same linaro-androidization-tracking on these trees to create Android kernels, a single unified Android kernel should be possible to generate automatically from the unified vanilla one and I'll look at starting that after Panda tracking is in better shape. -Andy -- Andy Green | TI Landing Team Leader Linaro.org │ Open source software for ARM SoCs | Follow Linaro http://facebook.com/pages/Linaro/155974581091106 - http://twitter.com/#!/linaroorg - http://linaro.org/linaro-blog

QEMU status

by Michael Hudson-Doyle

Hi all, I've been working on testing images under QEMU with the lava-dispatcher (mostly this is preparation for testing A15 using a fast model, but it's interesting in its own right too). I think I have made the changes to the dispatcher I need (more about this in another mail) but I can't do an end-to-end test because QEMU doesn't seem to be working very well on my system (64-bit Oneiric, if that matters) -- it segfaults a few seconds into booting the beagle model. Here's what I've done today to check that it's not entirely the fault of how I'm doing things in the dispatcher: 1) Prepare images a) Latest image Dowloaded: http://snapshots.linaro.org/oneiric/linaro-o-developer/20111122/0/images/ta… http://snapshots.linaro.org/oneiric/omap3-oneiric/20111122/2/images/hwpack/… Ran: sudo linaro-media-create --hwpack ~/Downloads/hwpack_linaro-omap3_20111122-2_armel_supported.tar.gz --binary ~/Downloads/linaro-o-developer-tar-20111122-0.tar.gz --dev beagle --image_file beagle-latest.img b) 2011.10 image Downloaded: http://releases.linaro.org/11.10/ubuntu/oneiric-images/developer/linaro-o-d… http://releases.linaro.org/11.10/ubuntu/oneiric-hwpacks/hwpack_linaro-omap3… Ran: sudo linaro-media-create --hwpack ~/Downloads/hwpack_linaro-omap3_20111024-0_armel_supported.tar.gz --binary ~/Downloads/linaro-o-developer-tar-20111024-0.tar.gz --dev beagle --image_file beagle-2011.10.img --hwpack-force-yes 2) Run images $ qemu-system-arm -M beaglexm -drive if=sd,cache=writeback,file=beagle-2011.10.img -clock unix -device usb-kbd -device usb-mouse -usb -device usb-net,netdev=mynet -netdev user,id=mynet -nographic This gets into and through uboot, but segfaults soon after (full log in https://pastebin.linaro.org/327/).

Or should I be reporting all this as a bug? Cheers, mwh

U8500/Snowball how to release the second core from the trap?

by X Y

Hi, I am trying to enable the second core (For test purposes I am running my code from u-boot). For that I wrote address of routine for the second core at address U8500_BACKUPRAM0_BASE + UX500_CPU1_JUMPADDR_OFFSET and 0xA1FEED01 at U8500_BACKUPRAM0_BASE + UX500_CPU1_WAKEMAGIC_OFFSET . But nothing happened. Is there anything that I have to do in addition to that to have the second CPU jumped to the address specified in U8500_BACKUPRAM0_BASE + UX500_CPU1_JUMPADDR_OFFSET? BTW what is the address of the trap where the second core is running? Thanks

LAVA master images.

by Zygmunt Krynicki

Hi Dave. I need reference master images for our boards. Do we have an archive anywhere. I'm interested in Panda, iMX53 loco and snowball if you have them. One (panda) will do but I can use more once I can get them across the wire. Thanks ZK

[PATCH v2] ARM: OMAP2+: hwmod: Add a new state to handle hwmods left enabled at init

by Rajendra Nayak

An hwmod with a 'HWMOD_INIT_NO_IDLE' flag set, is left in enabled state by the hwmod framework post the initial setup. Once a real user of the device (a driver) tries to enable it at a later point, the hwmod framework throws a WARN() about the device being already in enabled state. Fix this by introducing a new state '_HWMOD_STATE_ENABLED_AT_INIT' to identify such devices/hwmods, so nothing but just a state change to '_HWMOD_STATE_ENABLED' can be done when the device/hwmod is requested to be enabled (the first time) by its driver/user. A good example of a such a device is an UART used as debug console. The UART module needs to be kept enabled through the boot, until the UART driver takes control of it, for debug prints to appear on the console.
