Hi guys,
I compile a native gdb using linaro 2011.10 by “./configure
--host=arm-none-linux-gnueabi --target=arm-none-linux-gnueabi”, and
the gdb runs on arm target boards directly.

Hi guys,
i tried cpuhotplug on pandaboard for both
Pandroid_Froyo_L27.8.2_release_pkg and Linaro 11.11. It has failed to
work stably.
On Pandroid_Froyo_L27.8.2_release_pkg, unplugging cpu1 works well:
# echo 0 > /sys/devices/system/cpu/cpu1/online
CPU1: shutdown
if i enable the cpu1 again by "echo
ok now. the reason is the powertop depends on
CONFIG_EVENT_POWER_TRACING_DEPRECATED, after selecting it, powertop
gets to work on SiRFprimaII.
Thanks

even there are still many discussions about data model and
device/function mapping, it is basically usable to CSR SiRFprimaII.
Then i moved the old prima2 pinmux to this framework and made some
basic tests.

Hi Linus,
Looks pretty good. just some minors.

Hi all,
i am using linaro uboot(u-boot-linaro-stable.git). i have let our
prima2 board support device tree with some workaround in uboot. two
problems i have meet:
1. device tree without ramdisk
now uboot used commands like
"bootm kernel_address ramdisk_address dtb_address"
to start linux kernel

Hi All,
I am a freshman to linaro. I found people sent some patches to
linaro-dev@lists.linaro.org. Here I have 2 questions:
1. Whether will linaro send those patches based on newest tree to
Linus' mainline or not? Or developers need to send those patches to
mainline by themselves?
Is there any do
