2019-07-24binman: Add support for CBFS entriesSimon Glass
Add support for putting CBFSs (Coreboot Filesystems) in an image. This allows binman to produce firmware images used by coreboot to boot. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-24binman: Add a utility library for coreboot CBFSSimon Glass
Coreboot uses a simple flash-based filesystem called Coreboot Filesystem (CBFS) to organise files used during boot. This allows files to be named and their position in the flash to be set. It has special features for dealing with x86 devices which typically memory-map their SPI flash to the top of 32-bit address space and need a 'boot block' ending there. Create a library to help create and read CBFS files. This includes a writer class, a reader class and associated other helpers. Only a subset of features are currently supported.

2019-07-24patman: Add a function to write ifwitoolSimon Glass
This tool has quite a few arguments and options, so put the functionality in a function so that we call it from one place and hopefully get it right. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-24binman: Pass the toolpath to testsSimon Glass
Tools like ifwitool may not be available in the PATH, but are available in the build. These tools may be needed by tests, so allow tests to use the --toolpath flag. Also use this flag with travis. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-23binman: Allow preserving test directoriesSimon Glass
Sometimes when debugging tests it is useful to keep the input and output directories so they can be examined later. Add an option for this and update the binman tests to support it. This affects both the test class and the tearDown() function called after each test. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-23binman: Allow verbosity control when running testsSimon Glass
At present the -v flag is ignored with tests, so that (for example) -v2 does not have any effect. Update binman to pass this flag through to tests so that they work just like running binman normally, except in a few special cases where we are actually testing behaviour with different levels of verbosity. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-23binman: Fix up the _DoTestFile() function -u argumentSimon Glass
This should be -u, not -up, since we don't need to preserve the output directory in this case. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-23binman: Support ELF files for TPLSimon Glass
We currenty support using the ELF file in U-Boot proper and SPL, but not TPL. Add this as it is useful both with sandbox and for CBFS to allow adding TPL as a 'stage'. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-23binman: Correct comment in u_boot_spl_elfSimon Glass
This comment mentions the wrong default filename. Fix it. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-23binman: Use tools compression function for blob handlingSimon Glass
Avoid duplicate code here by using the new compression function in the tools module. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-23binman: Drop unnecessary debug handlingSimon Glass
The -D option enables debug mode, but we only need to add -D to the command line once. Drop the duplicate code. Also drop the comment about enabling debugging since this can be done with -D. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-23binman: Use the tools.Decompress methodSimon Glass
Update the compression test to use the tools module to decompress the output data. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-23patman: Add functions to compress and decompress dataSimon Glass
Add utility functions to compress and decompress using lz4 and lzma algorithms. In the latter case these use the legacy lzma support favoured by coreboot's CBFS. No tests are provided as these functions will be tested by the CBFS tests in a separate patch. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-23binman: Allow text directly in the nodeSimon Glass
At present text entries use an indirect method to specify the text to use, with a label pointing to the text itself. Allow the text to be directly written into the node. This is more convenient in cases where the text is constant. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-23binman: Update entry.SetOffsetSize to be optionalSimon Glass
At present this function always sets both the offset and the size of entries. But in some cases we want to set only one or the other, for example with the forthcoming ifwi entry, where we only set the offset. Update the function to handle this. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-23binman: Don't assume there is an ME regionSimon Glass
At present having a descriptor means that there is an ME (Intel Management Engine) entry as well. The descriptor provides the ME location and assumes that it is present. For some SoCs this is not true. Before providing the location of a potentially non-existent entry, check if it is present. Update the comment in the ME entry also. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-23binman: Assume Intel descriptor is at the start of the imageSimon Glass
At present binman requires that the Intel descriptor has an explicit offset. Generally this is 0 since the descriptor is at the start of the image. Add a default to handle this, so users don't need to specify the offset. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-23binman: Ensure that coverage has access to site packagesSimon Glass
Code coverage tests fail on binman due to dist-packages being dropped from the python path on Ubuntu 16.04. Add them in so that we can find the elffile module, which is required by binman. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-23binman: Add a function to decode an ELF fileSimon Glass
Add a function which decodes an ELF file, working out where in memory each part of the data should be written. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-23binman: Add a function to create a sample ELF fileSimon Glass
It is useful to create an ELF file for testing purposes, with just the right attributes used by the test. Add a function to handle this, along with a test that it works correctly. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-23binman: Detect skipped testsSimon Glass
If tests are skipped we should ideally exit with an error, since there may be a missing dependency. However at present this is not desirable since it breaks travis tests. For now, just report the skips. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-23binman: Use a better error for missing Intel descriptorSimon Glass
FD is a bit confusing so write this out in full. Also avoid splitting the string so that people can grep for the error message more easily. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-23binman: Tidy up help for --indirSimon Glass
The current help is confusing. Adjust it to indicate what the flag actually does. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-23binman: Add missing comments toentrySimon Glass
At present GetOffsets() lacks a function comment. Add one. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-23binman: Add missing comments to bsectionSimon Glass
Some functions lack comments in this file. Add comments to cover this functionality. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-23binman: Add a --toolpath option to set the tool search pathSimon Glass
Sometimes tools used by binman may not be in the normal PATH search path, such as when the tool is built by the U-Boot build itself (e.g. mkimage). Provide a way to specify an additional search path for tools. The flag can be used multiple times. Update the help to describe this option. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-23patman: Add a way to set the search path for toolsSimon Glass
Sometimes tools can be located by looking in other locations. Add a way to direct the search. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-23binman: Add coverage tools info for Python 3Simon Glass
Test coverage with Python 3 requires a new package. Add details about this. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-23binman: Correct two typos in function names in ftestSimon Glass
Two functions have incorrect names. Fix them. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-23binman: Fix comment in bsection.GetEntries()Simon Glass
This comment is out of date as it does not correctly describe the return value. Fix it. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-23tools: Drop duplicate raise_on_error argumentSimon Glass
If kwargs contains raise_on_error then this function generates an error due to a duplicate argument. Fix this. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-23cbfs: Rename checksum to attributes_offsetSimon Glass
It seems that this field has been renamed in later version of coreboot. Update it. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-23cbfs: Add an enum and comment for the magic numberSimon Glass
This field is not commented in the original file. Add a comment. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-23x86: Add ifwitool for Intel Integrated Firmware ImageSimon Glass
Some Intel SoCs from about 2016 boot using an internal microcontroller via an 'IFWI' image. This is a special format which can hold firmware images. In U-Boot's case it holds u-boot-tpl.bin. Add this tool, taken from coreboot, so that we can build bootable images on apollolake SoCs. This tool itself has no tests. Some amount of coverage will be provided by the binman tests that use it, so enable building the tool on sandbox. Signed-off-by: Simon Glass <sjg@chromium.org>

2019-07-22rockchip: TPL banner should depend on CONFIG_TPL_BANNER_PRINTChris Webb
The generic code in common/spl/spl.c allows TPL/SPL banners to be silenced by unsetting CONFIG_TPL_BANNER_PRINT or CONFIG_SPL_BANNER_PRINT respectively. However, arch/arm/mach-rockchip/tpl.c prints this banner unconditionally. Fix the rockchip-specific tpl.c so that the TPL banner depends on CONFIG_TPL_BANNER_PRINT in the same way as the generic code.

2019-07-22rockchip: Fix TPL build without CONFIG_TPL_SERIAL_SUPPORTChris Webb
If CONFIG_DEBUG_UART is set but CONFIG_TPL_SERIAL_SUPPORT is not, the serial output should be available in SPL and full U-Boot, but not built in TPL. However, the rockchip tpl.c instead fails to compile with undefined references to the debug UART. Instead, initialise the debug UART and print the TPL banner only if both CONFIG_DEBUG_UART and CONFIG_TPL_SERIAL_SUPPORT are set.

The current implementation supports only binary file load. Add helpers to support ELF32 format (sanity check, and load).
