stackprot: Make our test a bit more complex

2021-05-24T18:23:01Z

With better compiler optimizations available, a compiler may see we do nothing with our buffer after calling memset and omit the call, thus causing us to not smash the stack. Add a comment to explain why we now also have a printf call, so that the test will pass as the memset will not be omitted. Reported-by: Marek Behún Signed-off-by: Tom Rini

cmd: mvebu: Rename rx_training to mvebu_comphy_rx_training

2021-05-16T04:48:45Z

Rename the misleading cmd "rx_training" to "mvebu_comphy_rx_training" to avoid confusion and mixup with DDR3/4 training. This makes it clear, that this command is platform specific and handles the COMPHY RX training. Also depend this cmd on ARMADA_8K and not TARGET_MVEBU_ARMADA_8K to make is available for OcteonTX2 CN913x.

cmd: add support for a new "extension" command

2021-05-13T17:09:05Z

This patch adds a new "extension" command, which aims at detecting extension boards connected to the hardware platform, and apply the Device Tree overlays that describe the hardware present on those extension boards. In order to enable this mechanism, board-specific code must implement the extension_board_scan() function that fills in a linked list of "struct extension", each describing one extension board. In addition, the board-specific code must select the SUPPORT_EXTENSION_SCAN Kconfig boolean. Based on this: - "extension scan" makes the generic code call the board-specific extension_board_scan() function to retrieve the list of detected extension boards. - "extension list" allows to list the detected extension boards. - "extension apply |all" allows to apply the Device Tree overlay(s) corresponding to one, or all, extension boards The latter requires two environment variables to exist and set one variable to run: - extension_overlay_addr: the RAM address where to load the Device Tree overlays - extension_overlay_cmd: the U-Boot command to load one overlay. Indeed, the location and mechanism to load DT overlays is very setup specific. - extension_overlay_name: set by the command: the name of the DT which will be load during the execution. When calling the command described in the extension_overlay_cmd variable, the variable extension_overlay_name will be defined. So a typical extension_overlay_cmd will look like this: extension_overlay_cmd=load mmc 0:1 $extension_overlay_addr /boot/$extension_overlay_name Here is an example on how to use it: => run loadfdt => fdt addr $fdtaddr => setenv extension_overlay_addr 0x1000 => setenv extension_overlay_cmd 'load mmc 0:1 ${extension_overlay_addr} /boot/${extension_overlay_name}' => extension scan Found 1 extension board(s). => extension apply 0 519 bytes read in 3 ms (168.9 KiB/s) Signed-off-by: Kory Maincent Reviewed-by: Maxime Ripard

cmd: gpt: Add option to write GPT partitions to environment variable

2021-05-04T16:52:46Z

This change would enhance the existing 'gpt read' command to allow (optionally) writing of the read GPT partitions to an environment variable in the UBOOT partitions layout format. This would allow users to easily change the overall partition settings by editing said variable and then using the variable in the 'gpt write' and 'gpt verify' commands.

phy: marvell: add RX training command

2021-04-29T05:45:24Z

This patch adds support for running RX training using new command called "rx_training" Usage: rx_training - rx_training RX training allows to improve link quality (for SFI mode) by running training sequence between us and the link partner, this allows to reach better link quality then using static configuration.
