[U-Boot] [PATCH 1/2] image: Implement IH_TYPE_KERNEL_ANYLOAD

[Marek Vasut]

> The legacy uImage format includes an absolute load and entry-point
> address. When bootm operates on a kernel uImage in memory that isn't
> loaded at the address in the image's load address, U-Boot will copy
> the image to its address in the header.
> 
> Some kernel images can actually be loaded and used at any arbitrary
> address. An example is an ARM Linux kernel zImage file. To represent
> this capability, IH_TYPE_KERNEL_ANYLOAD is implemented, which operates
> just like IH_TYPE_KERNEL, except that the load address header is
> ignored, and U-Boot does not copy the image to its load address, but
> rather uses it in-place.
> 
> This is useful when sharing a single (uImage-wrapped) zImage across
> multiple boards with different memory layouts; in this case, a specific
> load address need not be picked when creating the uImage, but instead
> is selected by the board-specific U-Boot environment used to load and
> boot that image.

Hi Stephen,

just a silly question, but didn't we agree on cmd_bootz? Or is this unrelated ?
