Igor Opaniuk 6d2c502afb feat(imx8m): obtain boot image set for imx8mn/mp ... In i.MX8MM/MQ it is possible to have two copies of bootloader in SD/eMMC and switch between them. The switch is triggered either by the BootROM in case the bootloader image is faulty OR can be enforced by the user, and there is API introduced in 9ce232fe ("feat(plat/imx8m): add SiP call for secondary boot"), which leverages this SoC feature. However neither i.MX8MP nor i.MX8MN have a dedicated bit which indicates what boot image set is currently booted. According to AN12853 [1] "i.MX ROMs Log Events", it is possible to determine whether fallback event occurred by parsing the BootROM event log. In case ROM event ID 0x51 is present,fallback event did occur and secondary boot image was booted. Knowing which boot image was booted might be useful for reliable bootloader A/B updates, detecting fallback event might be used for making decision if boot firmware rollback is required. This patche introduces implementation, that replicates the same imx_src_handler() behaviour as on i.MX8MM/MQ SoCs. The code is based on original U-Boot implementation [2].
