This region was added becasue there there are definitely GX devices which have secure memory in this area, and this patch will break those devices. > ## Booting kernel from Legacy Image at 08080000 ... > Image Name: kernel > Image Type: AArch64 Linux Kernel Image (lzma compressed) > Data Size: 4657736 Bytes = 4.4 MiB > Load Address: 0f080000 > Entry Point: 0f080000 > Verifying Checksum ...
