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>

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.

Using the HRESET_REQ register does not work. This board has no NOR flash, and can only be booted via SD or SPI. This procedure is documented in Freescale Document Number AN3659 "Booting from On-Chip ROM (eSDHC or eSPI)."

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The localbus controller node in the device tree is typically a root node, even though the controller is part of CCSR. If we were to put the lbc node under the SOC node, then the 'ranges' property in the lbc node would translate through the 'ranges' property of the parent SOC node, and we don't want that. Since the lbc is a separate node, it's possible for the 'reg' property to be wrong. This happened with the original version of p1022ds.dts, which used a 32-bit value in the 'reg' address, instead of a 36-bit address.

Both the QE and the Fman use the QE Firmware binary format to package their respective microcode data, which is why the same macros are used for both. A given SOC will only have a QE or an Fman, so this is safe. Unfortunately, the current macro definition and usage has inconsistencies. For example, CONFIG_SYS_FMAN_FW_ADDR was used to define the address of Fman firmware in NOR flash, but CONFIG_SYS_QE_FW_IN_NAND contains the address of NAND. There's no way to know by looking at a variable how it's supposed to be used. In the future, the code which uploads QE firmware and Fman firmware will be merged.

| * | x86: Fix some bugs in the i8402 driver when no controller is presentGabe Black2011-11-29-1/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If no controller is present, the i8402 driver should return immediately and not attempt to operate on the missing hardware. In kbd_input_empty, the status register is checked every millisecond to see whether the input buffer is empty, up to a timeout which is tracked by decrimenting a counter each time the check is performed. The decrement is performed with a postfix -- operator, and the value of the counter is checked in place. That means that when the counter reaches zero and the loop terminates, it will actually be decrimented one more time and become -1. That value is returned as the return value of the function. That would give the right answer if it wasn't for that extra decrement because a timeout would indicate that the buffer never became empty. This change fixes both of those bugs.

| * | x86: Wrap small helper functions from libgcc to avoid an ABI mismatchGabe Black2011-11-29-0/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When gcc compiles some 64 bit operations on a 32 bit machine, it generates calls to small functions instead of instructions which do the job directly. Those functions are defined in libgcc and transparently provide whatever functionality was necessary. Unfortunately, u-boot can be built with a non-standard ABI when libgcc isn't. More specifically, u-boot uses -mregparm. When the u-boot and libgcc are linked together, very confusing bugs can crop up, for instance seemingly normal integer division or modulus getting the wrong answer or even raising a spurious divide by zero exception. This change borrows (steals) a technique and some code from coreboot which solves this problem by creating wrappers which translate the calling convention when calling the functions in libgcc. Unfortunately that means that these instructions which had already been turned into functions have even more overhead, but more importantly it makes them work properly. To find all of the functions that needed wrapping, u-boot was compiled without linking in libgcc. All the symbols the linker complained were undefined were presumed to be the symbols that are needed from libgcc. These were a subset of the symbols covered by the coreboot code, so it was used unmodified. To prevent symbols which are provided by libgcc but not currently wrapped (or even known about) from being silently linked against by code generated by libgcc, a new copy of libgcc is created where all the symbols are prefixed with __normal_. Without being purposefully wrapped, these symbols will cause linker errors instead of silently introducing very subtle, confusing bugs. Another approach would be to whitelist symbols from libgcc and strip out all the others. The problem with this approach is that it requires the white listed symbols to be specified three times, once for objcopy, once so the linker inserts the wrapped, and once to generate the wrapper itself, while this implementation needs it to be listed only twice. There isn't much tangible difference in what each approach produces, so this one was preferred. Signed-off-by: Gabe Black <gabeblack@chromium.org>

There are realmode_setup and bios_setup functions which prepare those blobs by copying them into the location they're supposed to run from, among other things. During u-boot relocation from ROM to RAM, the text and a few data segments are copied over. The realmode and bios sections are not copied, and so the only place they can be read from is their original location in the ROM. Looking specifically at the bios blob, there are symbols defined in the linker script called __bios_start and __bios_size which are defined to be the start and size of the blob in the ROM. In the bios_setup function, there seem to be two mistakes happening. First, the offset from ROM to RAM is being added to __bios_start which implies that this code expects to use the copy moved to RAM. No such copy is made, so that's wrong. More subtly, when u-boot relocates itself, it goes through all of the relocations stored in .rel.dyn and fixes them up. This has the effect of transforming the __bios_start reference in bios_setup so that it refers to the version in RAM (if one existed) instead of the one in ROM. To correct for that, the offset actually needs to be subtracted out again to translate the address back into the ROM. The net effect is that for both blobs, a + needs to be changed to a -.
