- Seperate the image file layout and ROM layout in the internal implementation
- Remove the payload region from image layout and add it into memory configuration.
When the payload is loaded into physical memory rather than the ROM space, image-rom mapping of other regions will not be affected if payload is at the start of the image file. Signed-off-by: Jiaqi Gao <[email protected]>
As the payload is moved to the beginning part of the image and is no longer adjacent to B, so the metadata section needs to be modified according to two cases: 1. If `exec-payload-section` feature is set, load payload in `Payload` section. 2. If the feature is not set, load payload into another `BFV` section. Signed-off-by: Jiaqi Gao <[email protected]>
Add ROM layout configuration in implementation to make it easier to calculate the ROM bases and image offsets. Signed-off-by: Jiaqi Gao <[email protected]>

Maximum size of ROM space is 16MiB which limits the size of payload image that can be contained by image. Signed-off-by: Jiaqi Gao <[email protected]>
