The stm32mp157c-dk2 image successfully boots only once. Subsequent boot attempts fail to reach U-Boot. The root cause turns out to be in U-Boot corruption during the first boot. The stm32mp1 U-Boot stores its environment at the end of GPT partition named 'ssbl' since v2020.10-rc2. However Buildroot genimage template for stm32mp157 boards creates 'ssbl' partition w/o extra space for U-Boot primary and redundant environments. This patch explicitly specifies 'ssbl' partition size that should be enough for both u-boot.stm32 image (~1M) and both environments (16K).
