This is the fourth version of patches for adding support for the
Turris Omnia board, a router developed by the CZ.NIC.
Modifications from last version:
- Since the new driver model API does not expose the
watchdog_reset function, only wdt_reset, the watchdog did not
get restarted and the device rebooted every 2 minutes in U-Boot.
These patches solve this problem.
- The SPI flash could not be accessed. I did not notice this since
during my testing I always uploaded the SPL image via serial
line. This is now also solved.
The first patch modifies Marvell's DDR3 training code to be more
general, so that board topology map can force 2t timing.
The second patch adds support for the hardware watchdog which
can be found on Omnia. I have modified the driver to use the new
driver model API.
The third patch adds the device tree for Turris Omnia taken from
Linux kernel and also armada-385-turris-omnia-u-boot.dtsi file
with some additions for U-Boot.
The fourth patch adds support for the I2C multiplexer found on
Turris Omnia.
The fifth patch adds support for the ATSHA204A CryptoAuthentication
chip, on which the Turris Omnia stores serial number and device MAC
address.
The sixth patch adds the proper support for the board. I have
modified config to use distro defaults as requested by Andreas
Faerber and also removed unnecessary comments.

This patch adds support for enforcing the 2t timing in struct hws_topology_map, through a new enum hws_timing, which can assume following values: HWS_TIM_DEFAULT - default behaviour, compute whether to enable 2t from the number of CSs HWS_TIM_1T - enforce 1t HWS_TIM_2T - enforce 2t This patch also sets all the board topology maps (db-88f6820-amc, db-88f6820-gp, controlcenterdc and clearfog) to have timing set to HWS_TIM_DEFAULT.

The problem is in pca954x_ofdata_to_platdata() where it does priv->width = dev_get_driver_data(dev); Which is now not the width but one of the enum values. It would work for 9457 or 9548 but I happen to be using a9544 which is 0 in the enum. I'll post a patch shortly to fix this. ^ permalink raw reply [flat|nested] 27+ messages in thread

The code is based on the Marvell/db-88f6820-gp by Stefan Roese with modifications from Tomas Hlavacek in the CZ.NIC turris-omnia-uboot repository, which can be found at https://gitlab.labs.nic.cz/turris/turris-omnia-uboot By default, the Turris Omnia uses btrfs as the main and only filesystem, and also loads kernel and device tree from this filesystem. Since U-Boot does not yet support btrfs, you should not flash your Turris Omnia board with this unless you know what you are doing.

I'm still facing trouble testing turris_omnia on latest v2018.01. First, that made me notice there's no README for how to test and deploy. I'm aware of temporary: sendbeacon /dev/ttyUSBx ./tools/kwboot -t -B 115200 /dev/ttyUSBx -b u-boot-spl.kwb -p # or without -p when s/BOOT_FROM spi/BOOT_FROM uart/ and permanent: tftpboot 0x1000000 u-boot-spl.kwb sf probe sf update 0x1000000 0 $filesize I used to have the original factory CZ.NIC U-Boot in SPI and booted test versions only via sendbeacon+kwboot. With mainline that appears to be broken - the CONFIG_ARMADA_38X code in arch/arm/mach-mvebu/spl.c seems to run into !boot_device and instead of UART tries to boot from SPI - nothing happens then and kwboot complains. I can force it to continue booting from UART by commenting out the if. So Stefan, it looks like your auto-detection is not working here and the Kconfig option to force it was dropped prematurely. When forcing UART, as soon as the progress surpasses 99%, it reboots into SPI SPL without any error message. Using the old U-Boot fork I've tried flashing u-boot-spl.kwb - similarly it gets stuck in the SPL trying to boot on from SPI. After a while it reboots, and so on in a loop. So it seems that non-SPL U-Boot 2018.01 is broken, on my 2 GB model. I also ran into a couple DDR3 training failures when booting via UART. No such training problems observed booting from SPI. Any hints appreciated.

Hmmm. Then some patch must have broken this UART boot-ability. Could you by any chance git-bisect, to check which patch broke this functionality? Perhaps some of the newer patches from Sean Nyekjaer? > When forcing UART, as soon as the progress surpasses 99%, it reboots > into SPI SPL without any error message. > Using the old U-Boot fork I've tried flashing u-boot-spl.kwb - similarly > it gets stuck in the SPL trying to boot on from SPI.

Thats strange. I have not really worked with Armada 38x for quite some time, but I don't remember any such problems that you describe here. I might need to dig up an Armada 38x board and give it a try myself... Thanks, Stefan ^ permalink raw reply [flat|nested] 27+ messages in thread

[Konstantin Porotchkin] Basically it will work with any Armada device, even with earlier KW SoCs. The difference is that 32-bit SoCs are mandating different image formats for different boot devices. We have removed this requirement from 64-bit models, so flash image format is the same for SPI, UART, or eMMC. For 32-bit devices you need to get UART image in order to use with this script. Marvell's A38x/A39x SDK build script always produces "uart recovery" image in addition to the requested boot device, so we never needed to convert the image on the fly as it is done by kwboot utility. > > Another comment: The kwboot tool is particularly handy in that -p allows > to send a binary u-boot-spl.kwb (such as from our Open Build Service) > with default of "BOOT_FROM spi" for turris_omnia here, without needing > to rebuild from sources with "BOOT_FROM uart" like I seem to need to for > mrvl_uart.sh. Are you planning to re-implement that for your script? [Konstantin Porotchkin] For supporting legacy devices we probably need to define some environment variable Something like "ARMADA_LEGACY" and if it set, the source flash image should be copied to a temporary location replacing the boot device and the checksum fields in the main header with "UART" and recalculated checksum value respectfully. Then such image could be used by the script as usual. I currently a bit busy with implementing support for the new Marvell SoC families, so cannot promise you to add legacy support shortly. I even do not have older platform boards on my work table for testing such support.
