binman: Add basic support for debugging performance

2021-07-21T16:27:35Z

One of binman's attributes is that it is extremely fast, at least for a Python program. Add some simple timing around operations that might take a while, such as reading an image and compressing it. This should help to maintain the performance as new features are added. This is for debugging purposes only. Signed-off-by: Simon Glass

binman: Support multithreading for building images

2021-07-21T16:27:35Z

Some images may take a while to build, e.g. if they are large and use slow compression. Support compiling sections in parallel to speed things up. Signed-off-by: Simon Glass (fixed to use a separate test file to fix flakiness)

binman: Automatically expand phase binaries into sections

2021-03-26T04:03:09Z

When creating an entry, check for an expanded version of that entry, then use it instead. This allows, for example use of: u-boot { }; instead of having to write out in full: u-boot { type = "section"; u-boot-nodtb { }; u-boot-dtb { }; }; Add an implementaion of this and associated documentation.

binman: Use standard filenames for SPL/TPL devicetree

2021-03-26T04:03:09Z

At present, before any entry expansion is done (such as a 'files' entry expanding out to individual entries for each file it contains), we check the binman definition (i.e. '/binman' node) to find out what devicetree files are used in the images. This is a pain, since the definition may change during expansion. For example if there is no u-boot-spl-dtb entry in the definition at the start, we assume that the SPL devicetree is not used. But if an entry later expands to include this, then we don't notice. In fact the flexibility provided by the current approach of checking the definition is not really useful. We know that we can have SPL and TPL devicetrees. We know the pathname to each, so we can simply check if the files are present. If they are present, we can prepare them and update them regardless of whether they are actually used. If they are not present, we cannot prepare/update them anyway, i.e. an error will be generated. Simplify state.Prepare() so it uses a hard-coded list of devicetree files. Note that state.PrepareFromLoadedData() is left untouched, since in that case we have a complete definition from the loaded file, but cannot of course rely on the devicetree files that created it still being present. So in that case we still check the image defitions. Signed-off-by: Simon Glass

binman: Drop unnecessary field in output_fdt_info

2021-03-26T04:03:09Z

At present we store an entry as the third field in output_fdt_info[]. This is only used to get the type of the entry. Of course multiple entries may have this same type. Also the entry type is the key to this dict, so we can use that instead. Drop the field and update GetUpdateNodes() to suit. Improve the comment for output_fdt_info a little while here.

binman: Use the fake SPL/TPL only if requested

2021-03-26T04:03:09Z

At present we always use the main devicetree for SPL/TPL as well when setting up the state. But this it not needed if there is a real devicetree for SPL or TPL. In fact it confuses things since we cannot distinguish between one being provided and using the fake one. Update the code to create the fakes only when requested. Put the mapping in a constant so we can use it elsewhere. Rename 'other_fname' to 'fname' while we are here since there is nothing 'other' about it. Signed-off-by: Simon Glass

binman: Support alignment of files

2021-01-30T21:25:41Z

When packing files it is sometimes useful to align the start of each file, e.g. if the flash driver can only access 32-bit-aligned data. Provides a new property to support this. Signed-off-by: Simon Glass

patman: Move to absolute imports

2020-04-26T20:25:21Z

At present patman sets the python path on startup so that it can access the libraries it needs. If we convert to use absolute imports this is not necessary. Move patman to use absolute imports. This requires changes in tools which use the patman libraries (which is most of them). Signed-off-by: Simon Glass

binman: Move to absolute imports

2020-04-26T20:25:21Z

At present binman sets the python path on startup so that it can access the libraries it needs. If we convert to use absolute imports this is not necessary. Move binman to use absolute imports. This enables removable of the path adjusting in Entry also. Signed-off-by: Simon Glass

binman: Update state when replacing device-tree entries

2019-07-29T15:38:06Z

Since the state module holds references to all the device trees used by binman, it must be updated when the device trees are updated. Add support for this. Signed-off-by: Simon Glass
