But finally with upstream TF-A v2.7 it is correctly set to 0x970000. This change was done since the final silicium has an SRAM size of 576KB where as the pre-silicium had only 512KB. The upstream TF-A has adapt it in verion v2.5 so the BL31 blob is at the end of the SRAM. Unfortunately they had (accidental) reverted back to 0x960000 in v2.6. They noticed that and changed (again) back to 0x970000. with v2.7. This commit also adapts the documentation for the i.MX8MP-EVK to reference the upstream TF-A. The new warning should point out that we strongly recommended to use versions from v2.7 onwards, due to the version mess explained above.
