[U-Boot] [PATCH v2] gpio: spear_gpio: Fix gpio_set_value() implementation
by Axel Lin 04 Jul '14

04 Jul '14

In current gpio_set_value() implementation, it always sets the gpio control bit no matter the value argument is 0 or 1. Thus the GPIOs never set to low. This patch fixes this bug. The address bus is used as a mask on read/write operations, so that independent software drivers can set their GPIO bits without affecting any other pins in a single write operation. Thus we don't need a read-modify-write to update the register.

[U-Boot] [PATCH v7 00/26] pmic: Redesign PMIC framework to support multiple instances of devices
by Lukasz Majewski 18 Apr '14

18 Apr '14

PMIC framework has been redesigned to support multiple instances of power related devices (e.g. fuel gauge, PMICs, chargers, micro USB IC, battery). Due to that, code at other architectures and boards have been adjusted properly. New power_init_board() method at ./lib/board.c file has been introduced. It is meant to be an architecture dependent function to support advanced power management. Since PMIC framework uses lists internally to link different devices, its initialization must be done just after malloc initialization. Please consider commits from this patch set as the example of advanced power management for a particular HW (Trats board in this case). In the new approach PMICs are selected with their names (e.g. 'pmic dump MAX8997_PMIC') Presented patch set is a first step to change 'pmic' command to more generic (i.e. power) to provide control for multiple devices. Moreover device's battery is treated as an oridinary "power" device (like PMIC). Due to that, framework unification is possible. For even more versalite design, each power device instance can specify its parent. For trats one can build a following scheme (it can de different for other boards): ----------------- --------| BAT |------------ | | | | | ----------------- | | | | \|/ \|/ \|/ ----------- ----------------- --------- |FG | |MUIC | |CHRG | | | | | | | ----------- ----------------- --------- Finally, this patch series also comprises of a "namespace" cleanup - an attempt to rename "pmic" to "power" to better reflect generality of this framework. Test HW: - Exynos4210 Trats development board - Exynos3 (C110) Goni development board Lukasz Majewski (26): pmic:i2c: Handle PMIC I2C transmission comprising of two bytes pmic:i2c: Add I2C sensor byte order (big/little) to PMIC framework pmic:max8997: Switch the MAX8997 PMIC to be used with multibus I2C pmic: Extend PMIC framework to support multiple instances of PMIC devices pmic: Introduce power_init_board() method at ./lib/board.c file pmic: Enable power_board_init() support at TRATS pmic:chrg: Common information about charger and battery (power_chrg.h) pmic: Move pmic related code to ./drivers/power directory pmic: Extend struct pmic to support battery and charger related operations pmic:battery: Support for Trats Battery at PMIC framework pmic:muic: Support for MUIC built into MAX8997 device pmic:fuel-gauge: Support for MAX17042 fuel-gauge pmic:max8997: Function for calculating LDO internal register value arm:trats:pmic: Default PMIC(MAX8997) initialization for Samsung's TRATS board arm:trats:pmic: Enable MUIC (MAX8997) at Samsung's TRATS board arm:trats:pmic: Enable fuel-gauge (MAX17042) at Samsung's TRATS board arm:trats:pmic: Enable battery support at Samsung's TRATS board pmic:max8997: Support for MAX8997 internal charger control arm:trats:pmic: Power consumption reduction state for Samsung's TRATS board arm:trats:pmic: Support for charging battery at Samsung's TRATS board pmic: Extend PMIC framework to support battery related commands power:pmic: Rename ./drivers/power/pmic_* to ./drivers/power/power_* files power:pmic: Rename CONFIG_PMIC* defines to CONFIG_POWER power:pmic: Rename CONFIG_DIALOG_PMIC defines to CONFIG_DIALOG_POWER arm:goni:pmic: Adjust GONI target platform board to new PMIC framework arm:universal_c210:pmic: Adjust C210 Universal target platform board to new PMIC framework Makefile | 5 +- arch/arm/lib/board.c | 8 + board/davedenx/qong/qong.c | 12 +- board/freescale/mx31pdk/mx31pdk.c | 12 +- board/freescale/mx35pdk/mx35pdk.c | 14 +- board/freescale/mx51evk/mx51evk.c | 12 +- board/freescale/mx53evk/mx53evk.c | 12 +- board/freescale/mx53loco/mx53loco.c | 21 +- board/genesi/mx51_efikamx/efikamx.c | 12 +- board/hale/tt01/tt01.c | 14 +- board/samsung/goni/goni.c | 22 +- board/samsung/trats/trats.c | 292 +++++++++++++++++++- board/samsung/universal_c210/universal.c | 27 ++- board/ttcontrol/vision2/vision2.c | 12 +- drivers/misc/Makefile | 7 -

[U-Boot] [PATCH 00/10] Add Marvell Dove and SolidRun CuBox
by Sebastian Hesselbarth 04 Mar '14

04 Mar '14

This patch set add support for the Marvell Dove 88AP510 SoC and the SolidRun CuBox board based on that SoC. The patch set is divided into the four following sections: (1) Patches 1-5: Add support for the Dove SoC and related drivers. Where possible drivers from Marvell Kirkwood are reused (mvsata, mvgbe), or forked to allow more generic usage (SPI, GPIO). The SDHCI driver is different and a new driver is added for it. The forked drivers can also be reused on Kirkwood but that would have required patching existing boards. (2) Patches 6-8: Allow mvgbe to use the phylib API, add support for 88E1310 PHY and allow Dove to use the driver. (3) Patch 9 Add the SolidRun CuBox as the first board based on Marvell Dove SoC. (4) Patch 10 Add support for different UART boot mode found on Dove.

[U-Boot] [PATCH 2/2] ARM: OMAP4/5: Remove dead code against CONFIG_SYS_ENABLE_PADS_ALL
by Jassi Brar 24 Jan '14

24 Jan '14

The commit f3f98bb0 : "ARM: OMAP4/5: Do not configure non essential pads, clocks, dplls" removed the config option aimed towards moving that stuff into kernel, which renders some code unreachable. Remove that code.

[U-Boot] [PATCH 1/2] ARM: OMAP4/5: Remove dead code against CONFIG_SYS_CLOCKS_ENABLE_ALL
by Jassi Brar 24 Jan '14

24 Jan '14

The commit f3f98bb0 : "ARM: OMAP4/5: Do not configure non essential pads, clocks, dplls" removed the config option aimed towards moving that stuff into kernel, which renders some code unreachable. Remove that code. Signed-off-by: Jassi Brar <jaswinder.singh(a)linaro.org> --- Hi, The commit f3f98bb0 seems to suggest we want to move these settings into the kernel, but perhaps we should also evaluate the option of making these inits fully board specific but in u-boot?

[U-Boot] U-boot for 64bit ARMv8
by Richard Schmitt 24 Jan '14

24 Jan '14

Is anyone considering porting/supporting uboot for ARMv8. Our initial investigation of boot loader support for ARMv8 indicates that the only boot loader currently being targeted is UEFI. The decisions we need to make are: - Do we move to UEFI on ARM? - Can we leverage someone else's enablement of ARMv8? - Do we provide our own enablement of ARMv8? Any opinions? Rich

[U-Boot] Boot Linux kernel with initramfs fails
by Axel Lin 17 Jan '14

17 Jan '14

Hi, When I boot Linux kernel with FIT Image, the kernel does not unpacking initramfs. ( The root cause is "initrd_start is NULL".) The initramfs is built-in with kernel, so I don't specify ramdisk in my kernel.its file. Is this a known issue or do I need special setting to boot a Linux kernel with initramfs? BTW, bootm shows below messages: => bootm ## Loading kernel from FIT Image at 00400000 ...
