[PATCH v8 0/4] Add SMDK5250 board support

by Chander Kashyap

This patchset add support for Samsung's SMDK5250 board based on EXYNOS5250 based SoC. It also adds support for MMC SPL booting. The porting is done by Samsung engineers at HQ in System LSI Team. I am contributing in upstreaming the code for the board. Based upon discussions following patches are dropped in this version: Exynos: Add CONFIG_EXYNOS4 Macro to EXYNOS4 based boards Exynos: Clock.c: Replace exynos4 prefix with exynos SMDK5250: enable device tree support is squashed with EXYNOS: Add SMDK5250 board support Chander Kashyap (4): Exynos: Clock.c: Use CONFIG_SYS_CLK_FREQ macro ARM: EXYNOS: Add support for Exynos5 based SoCs EXYNOS: Add SMDK5250 board support EXYNOS: SMDK5250: Add MMC SPL support MAINTAINERS | 1 + arch/arm/cpu/armv7/exynos/clock.c | 214 +++++++++++++- arch/arm/include/asm/arch-exynos/clock.h | 326 +++++++++++++++++++++ arch/arm/include/asm/arch-exynos/cpu.h | 35 +++- arch/arm/include/asm/arch-exynos/dmc.h | 146 ++++++++++ arch/arm/include/asm/arch-exynos/gpio.h | 99 ++++++- arch/arm/include/asm/arch-exynos/tzpc.h | 52 ++++ board/samsung/smdk5250/Makefile | 58 ++++ board/samsung/smdk5250/clock_init.c | 202 +++++++++++++ board/samsung/smdk5250/dmc_init.c | 462 ++++++++++++++++++++++++++++++ board/samsung/smdk5250/lowlevel_init.S | 96 ++++++ board/samsung/smdk5250/mmc_boot.c | 58 ++++ board/samsung/smdk5250/setup.h | 451 +++++++++++++++++++++++++++++ board/samsung/smdk5250/smdk5250.c | 146 ++++++++++ board/samsung/smdk5250/tzpc_init.c | 48 +++ boards.cfg | 1 + include/configs/s5pc210_universal.h | 1 + include/configs/smdk5250.h | 197 +++++++++++++ include/configs/trats.h | 1 + tools/Makefile | 6 + tools/mksmdk5250spl.c | 119 ++++++++ 21 files changed, 2702 insertions(+), 17 deletions(-) create mode 100644 arch/arm/include/asm/arch-exynos/dmc.h create mode 100644 arch/arm/include/asm/arch-exynos/tzpc.h create mode 100644 board/samsung/smdk5250/Makefile create mode 100644 board/samsung/smdk5250/clock_init.c create mode 100644 board/samsung/smdk5250/dmc_init.c create mode 100644 board/samsung/smdk5250/lowlevel_init.S create mode 100644 board/samsung/smdk5250/mmc_boot.c create mode 100644 board/samsung/smdk5250/setup.h create mode 100644 board/samsung/smdk5250/smdk5250.c create mode 100644 board/samsung/smdk5250/tzpc_init.c create mode 100644 include/configs/smdk5250.h create mode 100644 tools/mksmdk5250spl.c -- 1.7.5.4

native gdb for Android

by Barry Song

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. # gdb GNU gdb (Linaro GDB) 7.3-2011.10 Copyright (C) 2011 Free Software Foundation, Inc. License GPLv3+: GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html> This is free software: you are free to change and redistribute it. There is NO WARRANTY, to the extent permitted by law. Type "show copying" and "show warranty" for details. This GDB was configured as "arm-none-linux-gnueabi". For bug reporting instructions, please see: <http://bugs.launchpad.net/gdb-linaro/>. (gdb) I can use it to debug native programs on target boards directly. For example, attach process, set breakpoints, check registers and memory. One issue is I can't see multi-threads, for example: PID 646 is system_server by ps "646 1000 159m S system_server" Then I use gdb to attach it: # gdb attach 646 (gdb) info threads Id Target Id Frame * 1 process 646 "system_server" __ioctl () at bionic/libc/arch-arm/syscalls/__ioctl.S:15 as you see, “info threads” only shows one thread but there are several threads in system_server. But if I compile a new program based on glibc and gnu libthread, I can see multi-threads by the gdb. So my questions are: 1. Should I compile the native gdb using android toolchain and android bionic/libthread libraries? 2. Why can’t the current gdb capture multithreads for android processes? This question is actually about the theory for gdb to know multi-threads. In my opinion, both gnu and android use clone() to fork threads and threads in one process have same tgid in kernel and all threads return same getpid() value. Why not gdb just travel process lists to find multi-threads? Thanks Barry

[PATCH V6 0/7] add a generic cpufreq driver

by Richard Zhao

The driver is based on clock and regulator APIs and support single core and multi core ARM SoCs. For multi core, it assume all cores share the same clock and voltage. Thanks Arnd, Mark, Jamie, Shawn, Rob, for your review. Changes in V6: - add scaling_available_freqs Changes in V5: - add more comments - rename trans-latency to clk-trans-latency, and it only describe clk latency. Regulator latency is got from regulator_set_voltage_time. Changes in v4: - add depends on HAVE_CLK && OF && REGULATOR - add set_cpu_freq fail check - regulator_put wehn module exit - add pr_fmt and convert all printk to pr_xxx - use voltage range - comment and doc fix - add cpu_volts value pre-check in module init - add helpfull module parameter max_freq - remove compatible string check on Arnd's comment. - remove generic-cpufreq to clk-reg-cpufreq Changes in v3: - move adjusting smp loops_per_jiffy to arm common code, and also adjust global loops_per_jiffy. - remove adjusting loops_per_jiffy in imx and omap cpufreq drivers. - check compatible "generic-cpufreq" when module_init - change printk to pr_xxx - add generic-cpufreq DT binding doc Changes in v2: - add volatage change support - change '_' in property name to '-' - use initial value to calculate loops_per_jiffy - fix reading cpu_volts property bug - let cpufreq_frequency_table_cpuinfo routines handle cpu_freq_khz_max/min - don't change freq in arm_cpufreq_exit, because every core share the same freq. - use unsigned long describe frequency as much as possible. Because clk use unsigned long, but cpufreq use unsigned int. [PATCH V6 1/7] ARM: add cpufreq transiton notifier to adjust [PATCH V6 2/7] arm/imx: cpufreq: remove loops_per_jiffy recalculate [PATCH V6 3/7] cpufreq: OMAP: remove loops_per_jiffy recalculate for [PATCH V6 4/7] cpufreq: add clk-reg cpufreq driver [PATCH V6 5/7] dts/imx6q: add cpufreq property [PATCH V6 6/7] arm/imx6q: register arm_clk as cpu to clkdev [PATCH V6 7/7] arm/imx6q: select ARCH_HAS_CPUFREQ Thanks Richard

Efika MX Smartbook + serial dongle needed at Linaro Connect

by Marcin Juszkiewicz

Hi Looks like I managed to break serial port on my Efika MX Smartbook today. As there are people in Linaro with this device I am asking for help. For this I need someone with Efika MX Smartbook and debug board to be present at conference. I will take my netbook and dongle so will be able to check is it dongle or Efika which broke for me. If you have both and have no use for them I can take it from you - will have no problems finding someone here wanting to play & hack on Efika ;)

The earliest release build for imx35 appears to be https://android-build.linaro.org/builds/~linaro-android/leb-imx53-11.07-rel… , and from a quick look that's even 2.3.4. Not sure about the kernel though, please check yourself - even though it's 2.3.4, we might have used much newer kernel than AOSP 2.3.4 (well, that's what Linaro does - leverages and tests newer technologies so vendors and community were more comfortable with adopting them). > BR > > Tugrul > -- Best Regards, Paul Linaro.org | Open source software for ARM SoCs Follow Linaro: http://www.facebook.com/pages/Linaro http://twitter.com/#!/linaroorg - http://www.linaro.org/linaro-blog

[RFC] Upcoming work view for individual engineers

by Guilherme Salgado

Hi folks, We're trying to make status.l.o more useful to engineers and the first thing we're planning to do is a new page listing the upcoming work assigned to a given person. I'm attaching a mockup of that view here and we'd like to know what you think of it... Do you think that would be useful to you? Is there any other information you'd like to see there, or maybe a different way to present/group them? Cheers, -- Guilherme Salgado <https://launchpad.net/~salgado>
