* image: Implement IH_TYPE_KERNEL_NOLOADStephen Warren2011-12-01-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | 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_NOLOAD 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. v2: Rename from IH_TYPE_KERNEL_ANYLOAD to IH_TYPE_KERNEL_NOLOAD.

* checkpatch whitespace cleanupsStephen Warren2011-10-22-28/+28
| | | | | | | | | | | | | | | | | | | | | | This avoids the following checkpatch warning in later patches: ERROR: "(foo*)" should be "(foo *)" ERROR: space required before the open brace '{' ERROR: space prohibited before that close parenthesis ')' ERROR: spaces required around that '||' (ctx:WxV) WARNING: space prohibited between function name and open parenthesis '(' WARNING: line over 80 characters This fixes all the white-space warnings/errors in my subsequent patch, and within this current patch. A number of other checkpatch warnings and errors are still present in this patch itself, but are beyond simple whitespace fixes, so are not solved by this patch. v2: New patch Signed-off-by: Stephen Warren <swarren@nvidia.com> Tested-by: Simon Glass <sjg@chromium.org> Tested-by: Simon Glass <sjg@chromium.org>
* tools: mkimage: split code into core, default and FIT image specificPrafulla Wadaskar2009-09-10-0/+149
This is a first step towards reorganizing the mkimage code to make it easier to add support for additional images types. Current mkimage code is specific to generating uImage and FIT image files, but the same framework can be used to generate other image types like Kirkwood boot images (kwbimage-TBD). For this, the mkimage code gets reworked: Here is the brief plan for the same:- a) Split mkimage code into core and image specific support b) Implement callback functions for image specific code c) Move image type specific code to respective C files Currently there are two types of file generation/list supported (i.e uImage, FIT), the code is abstracted from mkimage.c/.h and put in default_image.c and fit_image.c; all code in these file is static except init function call d) mkimage_register API is added to add new image type support All above is addressed in this patch e) Add kwbimage type support to this new framework (TBD) This will be implemented in a following commit.
