As with other platforms vendors love to create their own boot header formats. Xilinx is no different and for the Zynq platform/SoC there exists the "boot.bin" which is read by the platforms bootrom. This format is described to a useful extent within the Xilinx Zynq TRM. This implementation adds support for the 'zynqimage' to mkimage. The implementation only considers the most common boot header which is un-encrypted and packed directly after the boot header itself (no XIP, etc.). However this implementation does take into consideration the other fields of the header for image dumping use cases (vector table and register initialization).

|
|
* Image Types
|
|
*
|
|
* "Standalone Programs" are directly runnable in the environment
|
|
* provided by U-Boot; it is expected that (if they behave
|
|
* well) you can continue to work in U-Boot after return from
|
|
* the Standalone Program.
|
|
* "OS Kernel Images" are usually images of some Embedded OS which
|
|
* will take over control completely. Usually these programs
|
|
* will install their own set of exception handlers, device
|
|
* drivers, set up the MMU, etc. - this means, that you cannot
|
|
* expect to re-enter U-Boot except by resetting the CPU.
|
|
* "RAMDisk Images" are more or less just data blocks, and their
|
|
* parameters (address, size) are passed to an OS kernel that is
|
|
* being started.
|
|
* "Multi-File Images" contain several images, typically an OS
|
|
* (Linux) kernel image and one or more data images like
|
|
* RAMDisks. This construct is useful for instance when you want
|
|
* to boot over the network using BOOTP etc., where the boot
|
|
* server provides just a single image file, but you want to get
|
|
* for instance an OS kernel and a RAMDisk image.
|
|
*
|
|
* "Multi-File Images" start with a list of image sizes, each
|
|
* image size (in bytes) specified by an "uint32_t" in network
|
|
* byte order. This list is terminated by an "(uint32_t)0".
|
|
* Immediately after the terminating 0 follow the images, one by
|
|
* one, all aligned on "uint32_t" boundaries (size rounded up to
|
|
* a multiple of 4 bytes - except for the last file).
|
|
*
|
|
* "Firmware Images" are binary images containing firmware (like
|
|
* U-Boot or FPGA images) which usually will be programmed to
|
|
* flash memory.
|
|
*
|
|
* "Script files" are command sequences that will be executed by
|
|
* U-Boot's command interpreter; this feature is especially
|
|
* useful when you configure U-Boot to use a real shell (hush)
|
|
* as command interpreter (=> Shell Scripts).
