Integrate flash.sh script into image

[macpijan]

Integrate script from: 3mdeb/RteCtrl#22 into v0.8.X release

• Add recipe for flash.sh script to meta-rte and integrate it into image by default
• Remove this script from RteCtrl
• Scan Dasharo documentation references to flash.sh and remove them. Or leave a note that this flash.sh script is integrated on RTE OS v0.8.x or higher if needed, depending on the found case.
• Extend script with additional parameters/env variables, such as:
  • ability to select 1.8V vs 3.3V (currently it is hardcoded to 3.3V)
  • ability to provide some extra parameters to flashrom command (such as: -ifd -i fd -i me -i bios)

This is designed to have some working solution in a short term.

As suggested in 3mdeb/RteCtrl#22 (comment) already, this flash.sh script is not a perfect approach, and we already have something better with osfv_cli.

This can take a bit more time to discuss and implement, that is why we have a separate ticket for it here: #82

If you'd like to test the updated version of the script from: https://github.com/3mdeb/meta-rte/pull/83/files

The file can be downloaded here: https://raw.githubusercontent.com/3mdeb/meta-rte/c4c0f2b6c947061defa1b83bd585745ec0ecadb6/recipes-go/3mdeb-rtectrl/3mdeb-rtectrl/flash.sh

@wessel-novacustom did you have a chance to test this?

flashrom -p "$FLASHROM_PROGRAMMER" "$FLASHROM_PARAMS"

Is wrong.

It results in:

root@rte:~# ./flash.sh -V 3.3V probe
Setting SPI VCC to 3.3V
SPI lines ON
SPI Vcc ON
Probing ...
flashrom 1.4.0 on Linux 6.6.28 (armv7l)
flashrom is free software, get the source code at https://flashrom.org

Error: Extra parameter found.
Please run "flashrom --help" for usage info.
SPI Vcc OFF
SPI lines OFF

---

The fix would be:

flashrom -p "$FLASHROM_PROGRAMMER" $FLASHROM_PARAMS

So without the double quotes for the flashrom params.

---

I just made that change and tried:

root@rte:~# ./flash.sh -V 3.3V probe --flashrom-params "-o output.txt"

And that generated the output.txt file correctly, meaning that the flashrom params are still working, while now also without flashrom params.
