[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 2/2] T1040QDS: Add support of 2 stage SPI bootloader
by Priyanka Jain 26 Mar '14

26 Mar '14

Add support of 2-stage T1040QDS SPI bootloader using SPL framework. In this, PBL (hardware) initializes SRAM (256K) and copy SPL (192K) from SPI flash to SRAM and transfer control to SPL. This SPL bootloader furthur initializes DDR using SPD and environment and copy final u-boot image (512K) from SPI flash to DDR and transfer control to final u-boot.

[U-Boot] [RFC] ARM: U-boot and 2 GiB of ram with get_ram_size only being long
by Oliver Schinagl 24 Mar '14

24 Mar '14

Hey all, I just yesterday received my CubieTruck (cubieboard3) with 2 GiB of Ram and added support for it to the sunxi-u-boot branch. While I know this isn't merged into the main u-boot tree (yet), I ran into the following problem. At the end of the dram init code, it is customary to call get_ram_size() and return its value. This is then used to print the DRAM size and also is passed to the Linux kernel. However the return size of get_ram_size() is a long. While I don't understand why not unsigned long or even u64 was chosen, this causes get_dram_size to overflow when having a ramsize of 2 GiB. While only printing of the value isn't hugely important, this does indicate u-boot seems to be somewhat artificially limited to 2 GiB of Ram? This only seems to affect the SPL as, if I understood correctly, there it stores the ram_size into the gd struct which I think is unsigned long. I've started working on a patch to convert common/memsize.c's get_ram_size(), to be completely unsigned long, however there seems to be quite a lot of code that calls this. So my question is now before going over all drivers and change that and submit a big patch-set, did I overlook anything and are my conclusions correct, get_ram_size should return unsigned long. Finally, a long is 32 bits on x86 and armv7, but how will that relate to 64bits armv8? As I understood, Windows treats long's as 4 bytes no matter if it's 32 bit or 64 bit. Linux is better and a long is 4 bytes on 32 bits, and 8 bytes on 64 bits versions. So how will u-boot work on armv8? Will the long datatype work well, or should I consider changing things more future proof? (u32 and u64 come to mind). Thank you for any input regarding that issue. Oliver

[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 v2 00/13] ARMv7: add PSCI support to u-boot
by Marc Zyngier 26 Feb '14

26 Feb '14

PSCI is an ARM standard that provides a generic interface that supervisory software can use to manage power in the following situations: - Core idle management - CPU hotplug - big.LITTLE migration models - System shutdown and reset It basically allows the kernel to offload these tasks to the firmware, and rely on common kernel side code. More importantly, it gives a way to ensure that CPUs enter the kernel at the appropriate exception level (ie HYP mode, to allow the use of the virtualization extensions), even across events like CPUs being powered off/on or suspended. The main idea here is to turn some of the existing u-boot code into a separate section that can live in secure RAM (or a reserved page of memory), containing a secure monitor that will implement the PSCI operations. This code will still be alive when u-boot is long gone, hence the need for a piece of memory that will not be touched by the OS. This patch series contains 4 parts: - the first four patches are just bug fixes - the next three refactor the HYP/non-secure code to allow relocation in secure memory - the next three contain the generic PSCI code and DT infrastructure - the last three implement the CPU_ON method of the Allwinner A20 (aka sun7i). I realize the A20 u-boot code is not upstream yet (BTW is anyone actively working on that?), but hopefully that should give a good idea of how things are structured so far. The patches are against the sunxi u-boot tree as of today, and the first 10 patches will directly apply to mainline u-boot. As for using this code, it goes like this: sun7i# ext2load mmc 0:1 0x40008000 zImage ; ext2load mmc 0:1 0x60000000 sun7i-a20-cubietruck.dtb 2270120 bytes read in 117 ms (18.5 MiB/s) 9138 bytes read in 3 ms (2.9 MiB/s) sun7i# fdt addr 0x60000000 ; fdt resize ; fdt set ethernet0 mac-address "[5a fe b0 07 b0 07]" sun7i# setenv bootargs console=ttyS0,115200 earlyprintk ip=dhcp root=/dev/nfs nfsroot=/backup/a20_root,tcp sun7i# bootz 0x40008000 - 0x60000000 The kernel now boots in HYP mode, finds its secondary CPU without any SMP code present in the kernel, and runs KVM out of the box. Hopefully, the Xen/ARM guys can do the same fairly easily. This code has also been tested on a VExpress TC2, running KVM with all 5 CPUs, in order to make sure there was no obvious regression. I'm wildly cross-posting this patch series, including to lists I'm not subscribed to. Please keep me on Cc for any comment you may have. Cheers, M.

[U-Boot] [PATCH v5] Makefile: add a new script to check -fstack-usage support
by Masahiro Yamada 25 Feb '14

25 Feb '14

If -fstack-usage option is given to crosstools that do not support it, gcc displays a warning message but still exits with status 0. This means we can not rely on $(call cc-option,...) to detect if -fstack-usage option is supported or not. Signed-off-by: Masahiro Yamada <yamada.m(a)jp.panasonic.com> --- Some crosstools currently do not support -fstack-usage option. For example, bfin-uclinux-gcc, which is available at https://www.kernel.org/pub/tools/crosstool/ If -fstack-usage option is given to such crosstools, gcc displays a warning message as follows: warning: -fstack-usage not supported for this target [enabled by default] But it still exits with status 0. So, $(call cc-option,-fstack-usage) does not work as we expect because cc-option checks exit status to judge whether the given option is supported or not.
