[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] Chain loading an u-boot from an u-boot
by Helmut Raiger 09 Apr '14

09 Apr '14

Hi, to give you some background why we would want to do something (strange) like this: - we have a hardware design bug - we have a few hundred i.MX31 TT-01 devices in the field - the i.MX31 rom boot loader is only capable of using 1bit HW-ECC (loading the first page (2k) from the NAND) - the NAND chip specifies a requirement of 1bit ECC for the first 128kB (PEB) and 4bit ECC for the rest - our current u-boot uses 1-bit HW-ECC, the kernel uses UBIFS and 1bit HW-ECC - we face increasing bit errors in the field in the PEBs used by u-boot. Using UBIFS in the kernel mitigates the requirements of 4bit ECC for the whole NAND because it moves PEBs when bit errors show up. The real problem is the area where u-boot is located (currently approx. 450kB, including UBIFS, USB ethernet support and more ..). So the idea was: - use a small u-boot (<128kB) in the first PEB of the NAND (written with 1bit HW-ECC) that supports 4bit BCH - let it load a second u-boot (<512kB) from the next 4 PEBs (written with 4bit BCH) - jump to the second u-boot and load the kernel from an UBI volume using 1bit HW-ECC again I did all that and it seemed to work just fine, but jumping to the second u-boot almost always crashes the system. In detail we do: - romboot loads the SPL (2kb) - SPL loads the first u-boot stage (which relocates and runs nicely) - the first u-boot 'boots' the second u-boot by loading it from the NAND - the second u-boot is loaded to the link address minus 2kB (for SPL) - this is the same for the first and the second u-boot (link address 0x87e00000 - 0x800 = 0x87dff800) - it jumps to 0x87e00000 omitting the SPL for the second u-boot - the second u-boot should relocated itself again The second u-boot is verified in RAM with crc32 and it is valid. I've tested many configuration and found, that it only works if both u-boots are identical: - different builds of the same code work (different build date, but same code) - different configurations never work - it does not matter if cashes are turned on or off - I skipped the relocation of the second u-boot (actually not necessary) to no avail I also tried u-boot standalone applications which always work (after fixing a bug in u-boot r8<->r9 for gd), again independent of cashes. Using different configuration I never get any serial output of the second u-boot (board info) or debugging stuff. If I set a breakpoint in the second u-boot (after relocation) and continue from there it works until it tries to get the SPI clock (mxc_get_clock() when accessing CCM_CCMR) for the PMIC access. If I throw in a mxc_dump_clocks() earlier it hangs there. I'm pretty much running out of ideas, so any pointers are appreciated. Thx Helmut -- Scanned by MailScanner.

[U-Boot] [PATCH 00/11] arm: add Faraday A36x SoC platform support
by Kuo-Jung Su 07 Apr '14

07 Apr '14

From: Kuo-Jung Su <dantesu(a)faraday-tech.com> These patches introduce Faraday A36x SoC platform support. Here are some public documents for your reference. http://www.faraday-tech.com/html/documentation/index.html There is also a A369 QEMU emulator available at my github account: https://github.com/dantesu1218/qemu.git Here is quick start for QEMU: 1. Download the QEMU source tree $ git clone -b qemu-1.3.0 https://github.com/dantesu1218/qemu.git 2. Build & Install the QEMU: $ ./configure --target-list=arm-softmmu $ make $ make install 3. Launch u-boot with QEMU: $ qemu-system-arm -M a369 -m 512M -nographic -kernel ~/u-boot-2012.10/u-boot Kuo-Jung Su (11): arm: add MMU/d-cache support for Faraday cores net/ftgmac100: add MMU/D-cache support net: add FTMAC110 10/100Mbps ethernet support usb-ehci: add Faraday USB 2.0 EHCI controller support usb-gadget: add FOTG210 USB gadget support i2c: add FTI2C010 I2C controller support spi: add FTSPI010 SPI controller support mtd/nand: add FTNANDC021 NAND flash controller support mtd/spi: add FTSPI020 SPI Flash controller support mmc: add an alternative FTSDC010 driver support arm: add
