* | 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.

| | | | | | | | | | | | | | RSA provides a public key encryption facility which is ideal for image signing and verification. Images are signed using a private key by mkimage. Then at run-time, the images are verified using a private key. This implementation uses openssl for the host part (mkimage). To avoid bringing large libraries into the U-Boot binary, the RSA public key is encoded using a simple numeric representation in the device tree. Signed-off-by: Simon Glass <sjg@chromium.org>

This is useful when a single board may be stuffed with different eMMC devices, each of which has a different capacity, and you always want the environment to be stored at the very end of the device (or eMMC boot partition for example).

Fix requires PRM_RSTTIME.RSTTIME1 to be programmed with the time for which reset should be held low for the voltages and the oscillator to reach stable state. There are 3 parameters to be considered for calculating the time, which are mostly board and PMIC dependent. -1- Time taken by the Oscillator to shut + restart -2- PMIC OTP times -3- Voltage rail ramp times, which inturn depends on the PMIC slew rate and value of the voltage ramp needed. In order to keep the code in u-boot simple, have a way for boards to specify a pre computed time directly using the 'CONFIG_OMAP_PLATFORM_RESET_TIME_MAX_USEC' option. If boards fail to specify the time, use a default as specified by 'CONFIG_DEFAULT_OMAP_RESET_TIME_MAX_USEC' instead. Using the default value translates into some ~22ms and should work in all cases. However in order to avoid this large delay hiding other bugs, its recommended that all boards look at their respective data sheets and specify a pre computed and optimal value using 'CONFIG_OMAP_PLATFORM_RESET_TIME_MAX_USEC' In order to help future board additions to compute this config option value, add a README at doc/README.omap-reset-time which explains how to compute the value. Also update the toplevel README with the additional option and pointers to doc/README.omap-reset-time.

Used to implement regex operations on environment variables. Code size is ~ 3.5 KiB on PPC. To enable this code, define the CONFIG_REGEX option in your board config file. Note: There are more recent versions of the SLRE library available at http://slre.googlecode.com ; unfortunately, the new code has a heavily reorked API which makes it less usable for our purposes: - the return code is strings, which are more difficult to process - we don't get any information any more which sub-string of the data was matched by the given regex - it is much more cumbersome to work with arbitrary expressions, where for example the number of substrings for capturing are not known at compile time Also, there does not seem to be any real changes or improvements of the functionality. Because of this, we deliberately stick with the older code. Note 2: the test code (built when SLRE_TEST is defined) was modified to allow for more extensive testing; now we can test the regexp matching on all lines on a text file (instead of the whole data in the file as a single block).

* | flash: Add optional verify-after-write featureStefan Roese2013-04-22-0/+9
|/ | | | | | | | | | | | | Sometimes it might make sense to verify the written data to NOR flash. This patch adds this feature. To enable this verify-after-write, you need to define CONFIG_FLASH_VERIFY in your board config header. Please note that this option is useless in nearly all cases, since such flash programming errors usually are detected earlier while unprotecting/erasing/programming. Please only enable this option if you really know what you are doing. Signed-off-by: Stefan Roese <sr@denx.de>

* ARM: fix CONFIG_SPL_MAX_SIZE semanticsAlbert ARIBAUD2013-04-14-2/+16
| | | | | | | | | | | | | | | | | | | | Remove SPL-related ASSERT() in arch/arm/cpu/u-boot.lds as this file is never used for SPL builds. Rewrite the ASSERT() in arch/arm/cpu/u-boot-spl.lds to separately test image (text,data,rodata...) size, BSS size, and full footprint each against its own max, and make Tegra boards check full footprint. Also, output section mmutable is not used in SPL builds. Remove it. Finally, update README regarding the (now homogeneous) semantics of CONFIG_SPL_[BSS_]MAX_SIZE and add the new CONFIG_SPL_MAX_FOOTPRINT macro.
