2018-09-26sandbox: Fix set_working_fdt_addr usersAlexander Graf
When running sandbox with the new pointer sanitization we just recently introduced, we're running into a case with FIT images where we end up interpreting pointers as addresses. What happened is that most callers of set_working_fdt_addr() simply convert pointers into addresses without taking into account that they might be 2 separate address spaces. Fix the callers up to map their pointers into addresses. This makes sandbox tests pass for me again. Signed-off-by: Alexander Graf <agraf@suse.de>
2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

2018-02-18fdt: Implement weak arch_fixup_fdt()Alexey Brodkin
Only ARM and in some configs MIPS really implement arch_fixup_fdt(). Others just use the same boilerplate which is not good by itself, but what's worse if we try to build with disabled CONFIG_CMD_BOOTM and enabled CONFIG_OF_LIBFDT we'll hit an unknown symbol which was apparently implemented in arch/xxx/lib/bootm.c. Now with weak arch_fixup_fdt() right in image-fdt.c where it is used we get both items highlighted above fixed.

2017-05-01fdt: Move fdt_fixup_ethernet to a common placeTom Rini
With 3f66149d9fb4 we no longer have a common call fdt_fixup_ethernet. This was fine to do on PowerPC as they largely had calls already in ft_cpu_fixup. On ARM however we largely relied on this call. Rather than introduce a large number of changes to ft_cpu_fixup / ft_board_fixup we recognize that this is a common enough call that we should be doing it in a central location. Do it early enough that we can do any further updates in ft_cpu_fixup / ft_board_fixup.

Commit e2f88dfd2d96 ("libfdt: Introduce new ARCH_FIXUP_FDT option") allows us to skip memory setup of DTB, but a problem for ARM is that spin_table_update_dt() and psci_update_dt() are skipped as well if CONFIG_ARCH_FIXUP_FDT is disabled. This commit allows us to skip only fdt_fixup_memory_banks() instead of the whole of arch_fixup_fdt().

2016-10-13cmd/fdt: add possibilty to have 'extrasize' on fdt resizeHannes Schmelzer
Sometimes devicetree nodes and or properties are added out of the u-boot console, maybe through some script or manual interaction. The devicetree as loaded or embedded is quite small, so the devicetree has to be resized to take up those new nodes/properties. In original the devicetree was only extended by effective 4 * add_mem_rsv. With this commit we can add an argument to the "fdt resize" command, which takes the extrasize to be added.

2016-09-22image-fit: Fix fit_get_node_from_config semanticsPaul Burton
Commit bac17b78dace ("image-fit: switch ENOLINK to ENOENT") changed fit_get_node_from_config to return -ENOENT when a property doesn't exist, but didn't change any of its callers which check return values. Notably it didn't change boot_get_ramdisk, which leads to U-Boot failing to boot FIT images which don't include ramdisks with the following message: Ramdisk image is corrupt or invalid It also didn't take into account that by returning -ENOENT to denote the lack of a property we lost the ability to determine from the return value of fit_get_node_from_config whether it was the property or the configuration node that was missing, which may potentially lead callers to accept invalid FIT images. Fix this by having fit_get_node_from_config return -EINVAL when the configuration node isn't found and -ENOENT when the property isn't found, which seems to make semantic sense. Callers that previously checked for -ENOLINK are adjusted to check for -ENOENT, which fixes the breakage introduced by commit bac17b78dace ("image-fit: switch ENOLINK to ENOENT"). The only other user of the return fit_get_node_from_config return value, indirectly, is bootm_find_os which already checked for -ENOENT. From a read-through of the code I suspect it ought to have been checking for -ENOLINK prior to bac17b78dace ("image-fit: switch ENOLINK to ENOENT") anyway, which would make it right after this patch, but this would be good to get verified by someone who knows this x86 code or is able to test it.

2016-03-14Kconfig: Move CONFIG_FIT and related options to KconfigSimon Glass
There are already two FIT options in Kconfig but the CONFIG options are still in the header files. We need to do a proper move to fix this. Move these options to Kconfig and tidy up board configuration: CONFIG_FIT CONFIG_OF_BOARD_SETUP CONFIG_OF_SYSTEM_SETUP CONFIG_FIT_SIGNATURE CONFIG_FIT_BEST_MATCH CONFIG_FIT_VERBOSE CONFIG_OF_STDOUT_VIA_ALIAS CONFIG_RSA Unfortunately the first one is a little complicated. We need to make sure this option is not enabled in SPL by this change. Also this option is enabled automatically in the host builds by defining CONFIG_FIT in the image.h file. To solve this, add a new IMAGE_USE_FIT #define which can be used in files that are built on the host but must also build for U-Boot and SPL. Note: Masahiro's moveconfig.py script is amazing.

2015-06-05fdt: Pass the device serial number through devicetreePaul Kocialkowski
Before device-tree, the device serial number used to be passed to the kernel using ATAGs (on ARM). This is now deprecated and all the handover to the kernel should now be done using device-tree. Thus, this passes the serial-number property to the kernel using the serial-number property of the root node, as expected by the kernel. The serial number is a string that somewhat represents the device's serial number. It might come from some form of storage (e.g. an eeprom) and be programmed at factory-time by the manufacturer or come from identification bits available in e.g. the SoC.

If a specific configuraion is selected by the bootm command, e.g. with 'bootm 84000000#recoveryconf' we must honour this for not just the kernel, but also the ramdisk and FDT. In the conversion to using a common fit_image_load() function for loading images from FITs (commits a51ec63 and 53f375f) this feature was lost. Reinstate it by passing the selected configuration back from fit_image_load() to boot_get_kernel(), then use this configuration (which is stored in images->fit_uname_cfg) in both boot_get_ramdisk() and boot_get_fdt().

Also it isn't obvious that 'bootm' and 'bootm start' provide arguments in the same way. Adjust the code so that arguments are removed from the list before calling a sub-function.
