2015-08-13image-fdt.c: store returned error valueMax Krummenacher

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.

2015-04-18common: Make sure arch-specific map_sysmem() is definedJoe Hershberger
In the case where the arch defines a custom map_sysmem(), make sure that including just mapmem.h is sufficient to have these functions as they are when the arch does not override it. Also split the non-arch specific functions out of common.h Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Reviewed-by: Simon Glass <sjg@chromium.org>

2014-12-08fdt: Allow non-FDT kernels to boot when CONFIG_OF_LIBFDT is definedSuriyan Ramasami
The boot commands - bootz/bootm mandate a third argument which is the address to the FDT blob. In cases where this argument is not specified, boot fails with a message indicating a missing FDT. This causes non-FDT kernels to fail to boot. This patch allows both FDT and non-FDT kernels to boot by making the third parameter to the bootm/bootz optional.

It has been found that this change breaks the case of an appended device tree file, so for the problem in question some other solution must be found.

make the use of legacy image format configurable through the config define CONFIG_IMAGE_FORMAT_LEGACY. When relying on signed FIT images with required signature check the legacy image format should be disabled. Therefore introduce this new define and enable legacy image format if CONFIG_FIT_SIGNATURE is not set. If CONFIG_FIT_SIGNATURE is set disable per default the legacy image format.

2013-07-12bootm: Use selected configuration for ramdisk and fdtSimon Glass
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().

2013-06-26Clarify bootm OS argumentsSimon Glass
At present the arguments to bootm are processed in a somewhat confusing way. Sub-functions must know how many arguments their calling functions have processed, and the OS boot function must also have this information. 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. This means that all functions can know that argv[0] is the first argument of which they need to take notice. Signed-off-by: Simon Glass <sjg@chromium.org>

2013-05-14image: Add device tree setup to image librarySimon Glass
