u-boot-imx_2020.04_2.3.2-phy7.bb from dunfell is not buildable against poky/oe-core about meta-phytec

[smk-embedded]

Yes, this seems to be broken, as the receipt depends on python2 which got removed in dunfell. We currently test the Polis board only on zeus, which is the older NXP bsp and hardknott, which is the upcoming release. You can see all the build pipelines for the products on the correct soc branch in this repo:
https://git.phytec.de/phy2octo/
For the receipt: as u-boot 2020.04 should be already fully python3 compatible, changing this to python3 dependency should just work (without warranty, not tested)
Never the less, porting our NXP BSP to an upstream BSP on dunfell is quite the task. If you need more help, please get in contact. Regards, Stefan

My attempts look promising so far. Changes I had to do for a polis device:

PREFERRED_PROVIDER:virtual/kernel ?= "linux-imx"
DEPENDS:remove:pn-u-boot-imx = " python"
DEPENDS:append:pn-u-boot-imx = " bc-native python3"
ATF_MACHINE_NAME:pn-imx-boot = "bl31-imx8mm.bin"
ATF_MACHINE_NAME:pn-imx-boot-phytec = "bl31-imx8mm.bin"
PLATFORM:pn-imx-atf = "imx8mm"
SOC_TARGET:pn-imx-boot = "iMX8MM"
SOC_TARGET:pn-imx-boot-phytec = "iMX8MM"
IMXBOOT_TARGETS = "flash_evk"

I copied the imx-atf and imx-mkimage from dynamic-layers/fsl-bsp-release. I had to remove the dependency to imx-seco in the imx-mkimage recipe.

Currently I'm adapting u-boot-imx for my own boot scripts. As far as I can see, at least I don't really need the fsl-bsp-release layer.

One more thing: I have a a phytec polis device which doesnt match the MACHINE configuration exactly. I use phyboard-polis-imx8mm-4.conf for a "PB-02820-001.A1" device. Can you confirm that I use the correct one? The description of phyboard-polis-imx8mm-4.conf states that it is for PB-02820.A2 with 16GB emmc. I seem to have a 8GB emmc.

We have a initial Yocto master branch setup for i.MX8MP where we also don't use the fsl-bsp-release layer by moving the imx-atf and imx-mkimage to dynamic-layers/freescale-layer. So this has been done for newer branches of meta-phytec.

Using phyboard-polis-imx8mm-4.conf is save with PB-02820-001.A1. eMMC size is don't care for the machine. The first prototypes had 16GB. We are aware that the description is outdated and working on an update. At least for the upcoming hardknott based release.
