* fdt: Add option to default to most compatible conf in a fit imageGabe Black2012-11-12-0/+127
| | | | | | | | | | | | | | | | | | | | When booting a fit image with multiple configurations, the user either has to specify which configuration to use explicitly, or there has to be a default defined which is chosen automatically. This change adds an option to change that behavior so that a configuration can be selected explicitly, or the configuration which has the device tree that claims to be compatible with the earliest item in U-Boot's device tree. In other words, if U-Boot claimed to be compatible with A, B, and then C, and the configurations claimed to be compatible with A, D and B, D and D, E, the first configuration, A, D, would be chosen. Both the first and second configurations match, but the first one matches a more specific entry in U-Boot's device tree. The order in the kernel's device tree is ignored.

* image: Support FDTs already loaded at their load addressStephen Warren2012-03-06-3/+10
| | | | | | | | | | | | | boot_get_fdt() expects a uImage-wrapped FDT to be loaded to a staging location, and then memmove()s it to the load address specified in the header. This change enhances boot_get_fdt() to detect when the image has already been loaded to the correct address, and skip this memmove(). The detection algorithm was written to match the equivalent for the kernel; see bootm_load_os()'s IH_COMP_NONE case. v2: New patch Signed-off-by: Stephen Warren <swarren@nvidia.com>
* common/image.c: align usage of fdt_high with initrd_highShawn Guo2012-02-27-7/+5
| | | | | | | | | | | | | | | | | | The commit message of a28afca (Add uboot "fdt_high" enviroment variable) states that fdt_high behaves similarly to the existing initrd_high. But fdt_high actually has an outstanding difference from initrd_high. The former specifies the start address, while the later specifies the end address. As fdt_high and initrd_high will likely be used together, it'd be nice to have them behave same. The patch changes the behavior of fdt_high to have it aligned with initrd_high. The document of fdt_high in README is updated with an example to demonstrate the usage of this environment variable.

| | | | | | | | | | | | | We already flush the kernel image after we've loaded it to ensure visiblity to the other cores. We need to do the same thing for the ramdisk and device tree images. In AMP boot scenarios we might not be HW cache coherent with the secondary core that we are loading and setting the ramdisk and device tree up for. Thus we need to ensure we've flushed the regions of memory utilized by ramdisk and device tree so the loadding and any modifications (from decompression or fdt updates) are made visible to the secondary cores.

* image: Implement IH_TYPE_KERNEL_NOLOADStephen Warren2011-12-01-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* always relocate fdt into an lmb-allocated memory blockTimur Tabi2010-10-20-55/+28
| | | | | | | | | | | | | | | | | | | | | The device tree (fdt) must always exist in within the bootmap (usually the first 16MB of RAM). If it doesn't, then boot_relocate_fdt() will allocate an LMB region in the bootmap and copy the fdt into that region. It will also increase the size of the fdt. If the fdt is already in the bootmap, then previously the memory was just reserved. There was no contingency if the reservation failed, however. By always allocating an lmb region and copying/resizing the fdt into that region, the code is simplified and the memory region is always allocated properly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | boot_relocate_fdt is called on platforms with CONFIG_SYS_BOOTMAPSZ defined to relocate the device tree blob to be inside the boot map area between bootmap_base and bootmap_base+CONFIG_SYS_BOOTMAPSZ. For the case where the blob needs to be relocated, space is allocated inside the bootmap by calling lmb_alloc_base with size passed in plus some padding: of_len = *of_size + CONFIG_SYS_FDT_PAD; For the case where the blob is already inside the bounds of the boot map area, lmb_reserve is called to reserve the the space where the blob is already residing. The calculation for this case is currently: of_len = (CONFIG_SYS_BOOTMAPSZ + bootmap_base) - (ulong)fdt_blob; This is wrong because it reserves all the space in the boot map area from the blob to the end ignoring completely the actual size. The worst case is where the blob is at the beginning and the entire boot map area get reserved. Fix this by changing the length calculation to this: of_len = *of_size + CONFIG_SYS_FDT_PAD; This bug has likely never manifested itself because bootm has never been called with the fdt blob already in the bootmap area. In my testing on an OMAP3 beagle board I initially worked around the bug by simply moving the initial location of the fdt blob. I have tested with the new calculation with the fdt blob both inside and outside the boot map area. Signed-off-by: John Rigby <john.rigby@linaro.org>

* fdt relocate: have more attention to use a bootmap or notStephan Linz2010-08-08-0/+2
| | | | | | | | | | | | | | | | Platforms with flat device tree support can use a bootmap to relocate the fdt_blob. This is not a must. That's why the relocation function boot_relocate_fdt() should be use only if CONFIG_OF_LIBFDT was defined together with CONFIG_SYS_BOOTMAPSZ (see common/cmd_bootm.c). On MicroBlaze platforms there is no need to use a bootmap to relocate a fdt blob. So we need a more precise focus on the compilation and usage of boot_relocate_fdt(). In general it is valid to exclude the function boot_relocate_fdt() if the bootmap size CONFIG_SYS_BOOTMAPSZ is not defined. Signed-off-by: Stephan Linz <linz@li-pro.net>
* Fix condition where bootm_size not set and wrong memory size reportedMatthew McClintock2010-08-07-3/+9
| | | | | | | | | | | | | | If the user sets bootm_low and does not set bootm_size, u-boot will report the memory node in the flat device tree incorrectly. Instead of reporting the remaining size of memory, it will report the total available memory which is incorrect. Specifically this fixes the situation when booting a relocatable kernel and the memory is reported as an offset and size in the device tree, and the size needs to be adjusted accordingly.

* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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) { ...
