There are already two FIT options in Kconfig but the CONFIG options are still in the header files. We need to do a proper move to fix this. Move these options to Kconfig and tidy up board configuration: CONFIG_FIT CONFIG_OF_BOARD_SETUP CONFIG_OF_SYSTEM_SETUP CONFIG_FIT_SIGNATURE CONFIG_FIT_BEST_MATCH CONFIG_FIT_VERBOSE CONFIG_OF_STDOUT_VIA_ALIAS CONFIG_RSA Unfortunately the first one is a little complicated. We need to make sure this option is not enabled in SPL by this change. Also this option is enabled automatically in the host builds by defining CONFIG_FIT in the image.h file. To solve this, add a new IMAGE_USE_FIT #define which can be used in files that are built on the host but must also build for U-Boot and SPL. Note: Masahiro's moveconfig.py script is amazing.

/*

* Memory layout for where various images get loaded by boot scripts:
|
|
*
|
|
* I suspect address 0 is used as the SMP pen on the RPi2, so avoid this.
|
|
*
|
|
* fdt_addr_r simply shouldn't overlap anything else. However, the RPi's
|
|
* binary firmware loads a DT to address 0x100, so we choose this address to
|
|
* match it. This allows custom boot scripts to pass this DT on to Linux
|
|
* simply by not over-writing the data at this address. When using U-Boot,
|
|
* U-Boot (and scripts it executes) typicaly ignore the DT loaded by the FW
|
|
* and loads its own DT from disk (triggered by boot.scr or extlinux.conf).
|
|
*
|
|
* pxefile_addr_r can be pretty much anywhere that doesn't conflict with
|
|
* something else. Put it low in memory to avoid conflicts.
|
|
*
|
|
* kernel_addr_r must be within the first 128M of RAM in order for the
|
|
* kernel's CONFIG_AUTO_ZRELADDR option to work. Since the kernel will
|
|
* decompress itself to 0x8000 after the start of RAM, kernel_addr_r
|
|
* should not overlap that area, or the kernel will have to copy itself
|
|
* somewhere else before decompression. Similarly, the address of any other
|
|
* data passed to the kernel shouldn't overlap the start of RAM. Pushing
|
|
* this up to 16M allows for a sizable kernel to be decompressed below the
|
|
* compressed load address.
|
|
*
|
|
* scriptaddr can be pretty much anywhere that doesn't conflict with something
|
|
* else. Choosing 32M allows for the compressed kernel to be up to 16M.
|
|
*
|
|
* ramdisk_addr_r simply shouldn't overlap anything else. Choosing 33M allows
|
|
* for any boot script to be up to 1M, which is hopefully plenty.
