Updated data against Kirkstone release

[angolini]

I'm creating the PR so we can start review it, but I see the contribution sections are not good

@angolini thanks for working on this. I added a to do list so we work on items which we need to fix:

• contributions statistics
• ensure ventana board builds (old u-boot) or remove (@Ossanes)
• ensure imx6qdl-variscite-som board builds (old u-boot) or remove (@Ossanes)
• ensure imx7d-remarkable2 board builds (old u-boot) or remove (@Ossanes)
• improve SoC tree
• add p2020rdb machine description
• add SoC field on imx8dx-mek
• add SoC field on imx8dxl-ddr3l-evk
• add SoC field on imx8dxl-lpddr4-evk
• add SoC field on imx8qm-mek

@angolini, @Ossanes did part of this in Freescale/meta-freescale#1140

[angolini]

Is there any plan on the machines ventana, imx6qdl-variscite-som and imx7d-remarkable2, @Ossanes? I'm asking because if there is no plan to update it, I can remove them

[otavio]

If build fails, I'd remove.

[angolini]

ventana and imx7d-remarkable2 fails
imx6qdl-variscite-som works

I'm preparing the PR

[otavio]

@angolini I merged the PR removing the broken boards. Could you refresh the commit so we check next steps?

[angolini]

I'm on my way, but it takes some time... @otavio

Closing this as we are not working. In case we have time to go back to this, we can reopen.
