* image: Don't detect XIP images as overlapping.Stephen Warren2011-12-01-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | bootm_load_os() detects when it writes the decompressed image over the top of the compressed image. If this happens, the original image is corrupted. When the original image is a multi-component legacy image, or a (potentially multi-component) FIT image, this implies that other components may be corrupted. In turn, this means that booting is unlikely to be successful. However, in the case of no image compresssion coupled with an image with load address equal to where the image is already located (e.g. an XIP kernel, or IH_TYPE_KERNEL_ANYLOAD), there has been no copy and hence no corruption, no matter whether it's a single-component legacy image, a multi-component legacy image, or a FIT image. In this case, disable the overlap detection, and allow boot to continue. Without this change, when booting a single-component legacy image that contains an IH_TYPE_KERNEL_ANYLOAD, bootm_load_os() would have returned BOOTM_ERR_OVERLAP, but the caller ignores this, and boot continues and succeeds. Now, the false error is no longer even returned. Without this change, when booting a FIT image that contains an IH_TYPE_KERNEL_ANYLOAD, bootm_load_os() would have returned BOOTM_ERR_OVERLAP, which would then cause the caller to reset the board. Now, the false error is no longer returned, and boot succeeds. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Stefan Roese <sr@denx.de>
* image: Implement IH_TYPE_KERNEL_NOLOADStephen Warren2011-12-01-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Flush cache after the OS image is loaded into the memory.Diana CRACIUN2011-09-05-0/+3
| | | | | | | | | | | | | | | | Since we are loading an executable image into memory we need flush it out of the cache to possible maintain coherence on CPUs with split instruction and data caches. We do this for other executable image loading command. On PowerPC once we do this we no longer need to explicitly flush the dcache on multi-core systems in the BOOTM_STATE_OS_PREP phase. We now treat the BOOTM_STATE_OS_PREP as a no-op to maintain backwards compatibility with the bootm subcommand.

| | | | | | | | | The previous patch makes u-boot use the full accessible size of ram as the default boot mapped size if CONFIG_SYS_BOOTMAPSZ is not defined, which means boot_relocate_fdt() can be changed to depend solely on CONFIG_OF_LIBFDT. Signed-off-by: Grant Likely <grant.likely@linaro.org>

| | | | | | | | | | | | | | | | | | | | | | | | All arches except nios2 and microblaze call boot_get_fdt from bootm_start in common/cmd_bootm.c. Having nios2 and microblaze do so as well removes code from their respective do_bootm_linux routines and allows removal of a nasty ifdef from bootm_start. In the case where boot_get_fdt returns an error bootm_start returns and the platform specific do_bootm_linux routines will never get called. Also only check argv[3] for an fdt addr if argc > 3 first. This is already the case for nios2.

| | | | | | | | | | | | | | | | | | | This patch simplifies the use of CONFIG_SYS_MAX_FLASH_BANKS_DETECT. By moving these optional variables and defines into the common code, board specific code is minimized. Currently only the following board use this feature: APC405, IDS8247, TQM834x And IDS8247 doesn't seem to really need this feature, since its not updating the bank number variable at all. So this patch removes the definition of CONFIG_SYS_MAX_FLASH_BANKS_DETECT from this board port. This new framework will be used by the upcoming lwmon5 update as well.

* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-22/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hush shell dynamically allocates (and re-allocates) memory for the argument strings in the "char *argv[]" argument vector passed to commands. Any code that modifies these pointers will cause serious corruption of the malloc data structures and crash U-Boot, so make sure the compiler can check that no such modifications are being done by changing the code into "char * const argv[]". This modification is the result of debugging a strange crash caused after adding a new command, which used the following argument processing code which has been working perfectly fine in all Unix systems since version 6 - but not so in U-Boot: int main (int argc, char **argv) { while (--argc > 0 && **++argv == '-') { /* ====> */ while (*++*argv) { switch (**argv) { case 'd': debug++; break; ... default: usage (); } } } ... } The line marked "====>" will corrupt the malloc data structures and usually cause U-Boot to crash when the next command gets executed by the shell. With the modification, the compiler will prevent this with an error: increment of read-only location '*argv' N.B.: The code above can be trivially rewritten like this: while (--argc > 0 && **++argv == '-') { char *arg = *argv; while (*++arg) { switch (*arg) { ...
