[PATCH 1/3 v2] ARC: nSIM: switch from ARC UART to DW UART
by Alexey Brodkin 12 Feb '20

12 Feb '20

Since v2019.06 DesingWare nSIM supports DesignWare UART simulation and so we may switch from pretty unusual ARC UART to much more standard DesignWare UART (which in case of U-Boot is just an ordinary 16650 UART). This among other things makes built dinaries compatible with our other platforms to name a few: FPGA-based HAPS boards, QEMU and even ZeBU.

[PATCH v4 1/2] menu: Add a function to set the default by matching the item data
by Schrempf Frieder 12 Feb '20

12 Feb '20

From: Frieder Schrempf <frieder.schrempf(a)kontron.de> In order to make it possible to auto select a default entry by matching the data of the menu entries by an external matching function, we add some helpers and expose the menu_set_default_by_item_data_match() function.

dm, serial: problem with using ns16550 driver before relocation on mpc83xx

12 Feb '20

Hello Bin, Simon, I just porting the mpc83xx based kmcoge5ne board support DTS and got problems using the serial ns16550 driver. I need the serial driver before rolcation, so I enabled "u-boot,dm-pre-reloc;" as usual in the device tree, but board does not boot ... I found the commit: commit 4687919684e0e4390b9fc20d1809ecaa9dc3cb81 Author: Bin Meng <bmeng.cn(a)gmail.com> Date: Wed Oct 24 06:36:36 2018 -0700 serial: Remove DM_FLAG_PRE_RELOC flag in various drivers which added to the ns16550 serial driver: diff --git a/drivers/serial/ns16550.c b/drivers/serial/ns16550.c index 04b604fa2c..1e6fc6c668 100644 --- a/drivers/serial/ns16550.c +++ b/drivers/serial/ns16550.c @@ -487,7 +487,9 @@ U_BOOT_DRIVER(ns16550_serial) = { .priv_auto_alloc_size = sizeof(struct NS16550), .probe = ns16550_serial_probe, .ops = &ns16550_serial_ops, +#if !CONFIG_IS_ENABLED(OF_CONTROL) .flags = DM_FLAG_PRE_RELOC, +#endif }; #endif #endif /* SERIAL_PRESENT */ So, as OF_CONTROL is defined for me, the flag "u-boot,dm-pre-reloc" seems not working anymore ...

May I do something wrong here? I found in mainline for example the "arch/powerpc/dts/gdsys/gazerbeam-uboot.dtsi" board, which has the exactly same dts settings than I have now. @Dirk: Can you check, if this board boots with current mainline? Shouldn;t be the logic, that in case OF_CONTROL is enabled and if flag "u-boot,dm-pre-reloc" is set in DTS for the device, the device should be bound before relocation, and we do not need to check, if the driver sets DM_FLAG_PRE_RELOC ? But may I miss here something ...

[ANN] New PGP key for Tom Rini
by Tom Rini 12 Feb '20

12 Feb '20

Hey all, I see that I've let my current PGP key expire without creating a new one, once again. I've updated my previous key to expire 6 months from today. I've also created a new key that expires in 2 years with the ID of 1A3C7F70E08FAB1707809BBF147C39FF9634B72C and have signed it with my old key and uploaded it.

[PATCH] mips: cmd: go: Flush cache before jumping to app/image
by Stefan Roese 12 Feb '20

12 Feb '20

It has been noticed on MT7628/88 platforms, that booting the RAM image does not work reliably. Sometimes it works and sometimes not. Debugging showed that this "might" be a cache related issue as very strange errors occurred (e.g. output corrupted etc). This patch adds a cache flush for the complete SDRAM area to the go cmd before jumping to the entry point for the MIPS architecture. The complete area is flushed as we don't know at this point, how big the area of the "application" really is.

[ADMIN] Change of Mailing List configuration
by Wolfgang Denk 12 Feb '20

12 Feb '20

Hi all, the disappearing entries from the Cc: list of posting have not only caused some people to miss postings they would otherwise have read, but they are apparently also the reason for a growing number of DMARC related bounces. Therefore we decided not to waitany longer and have upgraded mailman to version 2.1.30rc1 which includes the new "drop_cc" config option, which is now set to "No". >From what we see, this seems to help both issues: - Cc: entries are no longer dropped - DMARK seems to be working find now with many mail servers that used to complain before (which is no surprise, as most of our postings have a number of mailing list members on Cc:) Hope this helps. Best regards, Wolfgang Denk -- DENX Software Engineering GmbH, Managing Director: Wolfgang Denk HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: (+49)-8142-66989-10 Fax: (+49)-8142-66989-80 Email: wd(a)denx.de The only perfect science is hind-sight.

[Question] SPL_SPI Invalid bus 0. SPI Probe failed.
by dvo 12 Feb '20

12 Feb '20

Good afternoon, I'm working on a variant of IMX6UL. I'd like to create SPL Uboot and put all of them on QSPI. The board has only QSPI NOR and NAND flashes so it's complicated for me since no SD card. I've searched and read from the internet but there's no any particular guide to show how to do that. However, I managed to configure the SPL build but I'm stuck for a long time at *SPI probe failed* issue from SPL_SPI. I've got the issue shown as follows: U-Boot SPL 2019.07-00008-g68b10d7fb7-dirty (Feb 12 2020 - 15:32:55 +0100) Trying to boot from SPI uclass_find_device_by_seq: 0 0 - not found uclass_find_device_by_seq: 1 0 - not found Invalid bus 0 (err=-19) SPI probe failed. SPL: failed to boot from all boot devices ### ERROR ### Please RESET the board ### I tested all suggestions but no luck at all. I put some configurations from the .dts file. ( I tried both dm-pre-reloc and dm-spl) &{/aliases} { u-boot,dm-pre-reloc; }; &aips1 { u-boot,dm-pre-reloc; }; &aips2 { u-boot,dm-pre-reloc; }; &iomuxc { u-boot,dm-pre-reloc; }; &pinctrl_qspi{ u-boot,dm-pre-reloc; }; &pinctrl_ecspi1{ u-boot,dm-pre-reloc; }; &pinctrl_ecspi2{ u-boot,dm-pre-reloc; }; &{/soc} { u-boot,dm-pre-reloc; }; &qspi { pinctrl-names = "default"; pinctrl-0 = <&pinctrl_qspi>; status = "okay"; ddrsmp=<0>; flash0: s25fl512s@0 { u-boot,dm-pre-reloc; #address-cells = <1>; #size-cells = <1>; compatible = "spansion,s25fl512s"; spi-max-frequency = <66000000>; spi-tx-bus-width = <4>; spi-rx-bus-width = <4>; num-cs = <2>; spi-cpol; spi-cpha; fast-read; m25p; reg= <0>; }; }; I also put the aliases in imx6ul.dtsi aliases { ethernet0 = &fec1; ethernet1 = &fec2; gpio0 = &gpio1; gpio1 = &gpio2; gpio2 = &gpio3; gpio3 = &gpio4; gpio4 = &gpio5; i2c0 = &i2c1; i2c1 = &i2c2; i2c2 = &i2c3; i2c3 = &i2c4; mmc0 = &usdhc1; mmc1 = &usdhc2; serial0 = &uart1; serial1 = &uart2; serial2 = &uart3; serial3 = &uart4; serial4 = &uart5; serial5 = &uart6; serial6 = &uart7; serial7 = &uart8; sai1 = &sai1; sai2 = &sai2; sai3 = &sai3; spi0 = &qspi; spi1 = &ecspi1; spi2 = &ecspi2; spi3 = &ecspi3; spi4 = &ecspi4; usbphy0 = &usbphy1; usbphy1 = &usbphy2; usb0 = &usbotg1; usb1 = &usbotg2; }; >From the defconfig file CONFIG_SPL_FRAMEWORK=y CONFIG_SPL_BUILD=y CONFIG_SPL=y CONFIG_SPL_SERIAL_SUPPORT=y CONFIG_SPL_LIBCOMMON_SUPPORT=y CONFIG_SPL_LIBGENERIC_SUPPORT=y CONFIG_SPL_SPI_FLASH_SUPPORT=y CONFIG_SPL_SPI_SUPPORT=y CONFIG_SPL_DM=y CONFIG_SPL_OF_LIBFDT=y CONFIG_SPL_MTD_SUPPORT=y CONFIG_SPL_OPTEE=y CONFIG_SPL_SPI_LOAD=y CONFIG_SPL_PINCTRL=y CONFIG_SPL_GPIO_SUPPORT=y CONFIG_SPL_DMA_SUPPORT=y With the build with uboot (without SPL), I'm able to load it directly from qspi and use the sf probe 0 to check: - spi0, /soc/aips-bus@02100000/qspi@021e0000 spi_get_bus_and_cs: Binding new device 'spi_flash@0:0', busnum=0, cs=0, driver=spi_flash_std sf probe 0 SF: Detected s25fl512s_256k with page size 256 Bytes, erase size 256 KiB, total 64 MiB What I'm not sure is if pinctrl are enable in SPL or not.
