[U-Boot] [RFC] arm: dts: am33xx: Sync DTS with Linux 4.16.11
by Felix Brack 12 Jul '18

12 Jul '18

Hello, I am working on a patch to synchronize the DTS files of the am33xx SoC with those from Linux 4.16.11 (current stable). After some tiny modifications to the boards am335x-pdu001, am335x-evm, am335x-rut, am437x-gp-evm and am43x-epos-evm buildman passes without any warnings on the 46 am33xx based boards. This is required but not sufficient at all. As I'm the maintainer of the am335x-pdu001 board I will use it to illustrate a sample problem. The am335x-pdu001 board uses the ns16550 driver which reads the property <reg-shift> from the DT. This property is required and must be set to a value of 2, otherwise it would default to 0. The am33xx.dtsi file currently used by U-Boot sets this property correctly for all 6 uarts. The am33xx.dtsi file from Linux 4.16.11 however does not define this property anymore. For the am335x-pdu001 board the fix is trivial: just add the property <reg-shift> to the board and U-Boot specific am335xx-pdu001-u-boot.dtsi file. But this has a major drawback: only the am335x-pdu001 board gets fixed. What about other boards requiring the <reg-shift> property? The first idea that would probably come into mind is to put the property <reg-shift> into the SoC specific am33xx-u-boot.dtsi file. But this file is ignored if a board specific file already exists. Hence this can not be done. For the patch I'm working on there is the general question about how to proceed. Should I just fix the board I'm maintaining and then post the patch? This would most certainly break some of the remaining 45 boards which I think is a no-go. A more specific question dealing with the "missing SoC property" <reg-shift> above is about <>-u-boot.dtsi files: would it be possible, useful and hazard-free to change the build process to use, for example, SoC specific _and_ board specific files? Of course some sort of hierarchy would be necessary to make sure that properties defined in the board specific dtsi file would overwrite the same properties defined in the SoC specific file ect. I believe that keeping DT files (especially include files) in sync between U-Boot and Linux is of big importance. Maybe there is already a standard solution to problems similar to the one depicted above. Anyway, I would appreciate any feedback. regards, Felix

[U-Boot] [RFC 0/8] i.MX: Add initial CLK support
by Jagan Teki 11 Jul '18

11 Jul '18

One of the blocking area where fec_mxc is unlikely to move dm can be CLK support, this series trying to add support for it and concentrated on ENET clocking for i.MX6QDL and i.MX6UL. I've verified this on i.MX6QDL, but the reason for sending this is an 'RFC' is there are some quite few issues with existing fec_mxc driver regarding mdio handling. The dm vs non-dm code in fec_mxc looks very uncomfortable to read and add new support, so I would like create one separate dm driver to make dm related changes if all agree? know issues: - CLK driver still using enable_fec_anatop_clock function to set the clock, but if we handling this in CLK we need anatop via OF_LIVE. will try this next version - fec_mxc is passing input ref clock, ENET_50MHZ. don't know how to make this dynamic, or this based on MII or any other feature, need help. - ipu_common has legacy clk support, since may boards are using ipu_common better to handle this via CLK so-that move to CLK become easy and meaningful. patch 1, clk/kconfig ordering patch 2, sample i.MX6QDL DM CLK template patch 3, 4 Implement ENET clocks for i.MX6QDL and i.MX6UL patch 5, add generic_clk_valid function patch 6, add CLK support in fec_mxc.c patch 7,8 enable CLK support on engicam boards Jagan Teki (8): clk: Kconfig: Ascending order to sub directiory kconfigs clk: Add DM CLK driver template for i.MX6QDL clk: imx: imx6q: Implement ENET clocks clk: imx: imx6ul: Implement ENET clocks clk: Add generic_clk_valid net: fec_mxc: Add clock support via CLK imx6ul: engicam: Enable CLK_IMX configs: icorem6_rqs: Enable CLK_IMX arch/arm/mach-imx/mx6/Kconfig | 2 + configs/imx6qdl_icore_rqs_defconfig | 1 + drivers/clk/Kconfig | 9 +-- drivers/clk/Makefile | 1 + drivers/clk/imx/Kconfig | 25 ++++++++ drivers/clk/imx/Makefile | 8 +++ drivers/clk/imx/clk_imx6q.c | 89 +++++++++++++++++++++++++++ drivers/clk/imx/clk_imx6ul.c | 95 +++++++++++++++++++++++++++++ drivers/net/fec_mxc.c | 58 ++++++++++++++++++ drivers/net/fec_mxc.h | 6 ++ drivers/video/ipu_common.c | 8 +++ include/clk-uclass.h | 10 +++ 12 files changed, 308 insertions(+), 4 deletions(-) create mode 100644 drivers/clk/imx/Kconfig create mode 100644 drivers/clk/imx/Makefile create mode 100644 drivers/clk/imx/clk_imx6q.c create mode 100644 drivers/clk/imx/clk_imx6ul.c -- 2.17.1

[U-Boot] [RFC PATCH 00/20] SPI-NAND support
by Miquel Raynal 11 Jul '18

11 Jul '18

During the last months, Boris Brezillon shared his work to support serial flashes within Linux. First, he delivered (and merged) a new layer called spi-mem. He also initiated in Linux MTD subsystem the move of all 'raw' NAND related code to a raw/ subdirectory, adding at the same time a NAND core that would be shared with all NAND devices. Then, he contributed a generic SPI-NAND driver, making use of this NAND core, as well as some vendor code to drive a few chips. On top of this work, I added an 'mtd' U-Boot command to handle all sort of MTD devices. This should become the default command instead of having one per flash flavor ('sf', 'nand', 'spi-nand' ?). The series has been tested on an Ocelot board PCB123 (VSC7514), featuring a Macronix SPI NAND chip. TL;DR: the series contains: - Various fixes and re-organization of the MTD subsystem. - The introduction of the SPI-mem interface. - The addition of the generic SPI-NAND driver (and its bindings). - Several SPI NAND chip drivers (Macronix, Micron, Winbond). - A new 'mtd' command. - DT changes to make use of a SPI NAND on the Ocelot board. Any comments on the code, the organization and the respect of U-Boot driver model will be welcome.

[U-Boot] Kconfiglib documentation generation
by Ulf Magnusson 11 Jul '18

11 Jul '18

Hello, Just as an FYI, Kconfiglib 2 (https://github.com/ulfalizer/kconfiglib) can generate nice Kconfig docs. See http://docs.zephyrproject.org/reference/kconfig/index.html for example output (warning: heavy page, lots of symbols). The script that generates the RST output for those docs is at https://github.com/zephyrproject-rtos/zephyr/blob/master/doc/scripts/genres…. It deals well with symbols defined in multiple locations as well (plenty of those in Zephyr too), listing each definition with the correct properties. I just added a patch to Kconfiglib that reduces the parsing time for the U-Boot Kconfigs from about four seconds to about half a second as well (Core i7 2600k). Those symbols defined in a million locations triggered some redundant work earlier. :) Cheers, Ulf
