mmc: Update environment variable with active partition

2021-06-22T04:02:46+00:00

This patch allows uboot scripts make choices about where to boot from based
on the active mmc boot partition. This allows having two copies of kernel,
filesystems etc, and choosing which to boot from based off of the active
bootloader partition.

cmd: pxe_utils: sysboot: fix crash if either board or soc are not set.

2021-06-18T08:29:17+00:00

If the environment does not have "soc" or "board" set, and fdtdir
option is specified in extlinux.conf, the bootloader will crash whilst
dereferencing a null pointer. Add a guard against null soc or
board. Fixes a crash of qemu-riscv64_smode configuration, which does
not have CONFIG_SYS_SOC defined.

stackprot: Make our test a bit more complex

2021-05-24T18:23:01+00:00

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.

cmd: mvebu: Rename rx_training to mvebu_comphy_rx_training

2021-05-16T04:48:45+00:00

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

2021-05-13T17:09:05+00:00

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
