* Add dumpimage, a tool to extract data from U-Boot imagesGuilherme Maciel Ferreira2013-12-13-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Given a multi-file image created through the mkimage's -d option: $ mkimage -A x86 -O linux -T multi -n x86 -d vmlinuz:initrd.img:System.map \ multi.img Image Name: x86 Created: Thu Jul 25 10:29:13 2013 Image Type: Intel x86 Linux Multi-File Image (gzip compressed) Data Size: 13722956 Bytes = 13401.32 kB = 13.09 MB Load Address: 00000000 Entry Point: 00000000 Contents: Image 0: 4040128 Bytes = 3945.44 kB = 3.85 MB Image 1: 7991719 Bytes = 7804.41 kB = 7.62 MB Image 2: 1691092 Bytes = 1651.46 kB = 1.61 MB It is possible to perform the innverse operation -- extracting any file from the image -- by using the dumpimage's -i option: $ dumpimage -i multi.img -p 2 System.map Although it's feasible to retrieve "data files" from image through scripting, the requirement to embed tools such 'dd', 'awk' and 'sed' for this sole purpose is cumbersome and unreliable -- once you must keep track of file sizes inside the image. Furthermore, extracting data files using "dumpimage" tool is faster than through scripting.

| * | bootcount: store bootcount var in environmentHeiko Schocher2013-11-11-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If no softreset save registers are found on the hardware "bootcount" is stored in the environment. To prevent a saveenv on all reboots, the environment variable "upgrade_available" is introduced. If "upgrade_available" is 0, "bootcount" is always 0 therefore no need to save the environment on u-boot boot, if "upgrade_available" is 1 "bootcount" is incremented in the environment and environment gets written on u-boot start. So the Userspace Applikation must set the "upgrade_available" and "bootcount" variable to 0 (for example with fw_setenv), if a boot was successfully. Signed-off-by: Heiko Schocher <hs@denx.de>

* | dfu: ram supportAfzal Mohammed2013-09-24-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DFU spec mentions it as a method to upgrade firmware (software stored in writable non-volatile memory). It also says other potential uses of DFU is beyond scope of the spec. Here such a beyond the scope use is being attempted - directly pumping binary images from host via USB to RAM. This facility is a developer centric one in that it gives advantage over upgrading non-volatile memory for testing new images every time during development and/or testing. Directly putting image onto RAM would speed up upgrade process. This and convenience was the initial thoughts that led to doing this, speed improvement over MMC was only 1 second though - 6 sec on RAM as opposed to 7 sec on MMC in beagle bone, perhaps enabling cache and/or optimizing DFU framework to avoid multiple copy for ram (if worth) may help, and on other platforms and other boot media like NAND maybe improvement would be higher. And for a platform that doesn't yet have proper DFU suppport for non-volatile media's, DFU to RAM can be used. Another minor advantage would be to increase life of mmc/nand as it would be less used during development/testing. usage: <image name> ram <start address> <size> eg. kernel ram 0x81000000 0x1000000 Downloading images to RAM using DFU is not something new, this is acheived in openmoko also. DFU on RAM can be used for extracting RAM contents to host using dfu upload. Perhaps this can be extended to io for squeezing out register dump through usb, if it is worth.

* TPL : introduce the TPL based on the SPLYing Zhang2013-08-20-0/+16
| | | | | | | | | | | | | | | | Due to the nand SPL on some board(e.g. P1022DS)has a size limit, it can not be more than 4K. So, the SPL cannot initialize the DDR with the SPD code. This patch introduces TPL to enable a loader stub that is loaded by the code from the SPL. It initializes the DDR with the SPD or other operations. The TPL's size is sizeable, the maximum size is decided by the memory's size that TPL runs. It initializes the DDR through SPD code, and copys final uboot image to DDR.

So there are two stage uboot images: * spl_boot, 96KB size. The env variables are copied to L2 SRAM, so that ddr spd code can get the interleaving mode setting in env.

* | Licenses: introduce SPDX Unique Lincense IdentifiersWolfgang Denk2013-07-24-18/+2
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Like many other projects, U-Boot has a tradition of including big blocks of License headers in all files. This not only blows up the source code with mostly redundant information, but also makes it very difficult to generate License Clearing Reports. An additional problem is that even the same lincenses are referred to by a number of slightly varying text blocks (full, abbreviated, different indentation, line wrapping and/or white space, with obsolete address information, ...) which makes automatic processing a nightmare. To make this easier, such license headers in the source files will be replaced with a single line reference to Unique Lincense Identifiers as defined by the Linux Foundation's SPDX project [1]. For example, in a source file the full "GPL v2.0 or later" header text will be replaced by a single line: SPDX-License-Identifier: GPL-2.0+ We use the SPDX Unique Lincense Identifiers here; these are available at [2]. Note: From the legal point of view, this patch is supposed to be only a change to the textual representation of the license information, but in no way any change to the actual license terms. With this patch applied, all files will still be licensed under the same terms they were before. Note 2: The apparent difference between the old "COPYING" and the new "Licenses/gpl-2.0.txt" only results from switching to the upstream version of the license which is differently formatted; there are not any actual changes to the content. Note 3: There are some recurring questions about linense issues, such as: - Is a "All Rights Reserved" clause a problem in GPL code? - Are files without any license header a problem? - Do we need license headers at all? The following excerpt from an e-mail by Daniel B. Ravicher should help with these: | Message-ID: <4ADF8CAA.5030808@softwarefreedom.org> | Date: Wed, 21 Oct 2009 18:35:22 -0400 | From: "Daniel B.
