Stm32mp1 Yocto Kirkstone issues

Hi @hwintermark ,
Yes I pushed the changes. I trayed to explain in the readme what you need to do also for first flash with STMCubeProgrammer with eMMC and SD card ( I didn’t tested for SD card because my system has only eMMC).
also I added some commented ffsbl1 and fsbl2 partitions build if you need it for SD card flash layout.
There is a difference because in eMMC there a special partition for fsbl1 and 2 (boot1 and boot2) so you cannot write it with the RawImage like gptimg therefore for eMMC you need flash the fsbl1 and 2 the regular way and the gptimg starts with the metadata.bin without fsbl1,2 .
I hope it helped also i will appreciate if you will write what i need to change in readme or other places so it will be more understandable for everyone .
