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

We don't need these now that the tools using Python 3. Drop them. Signed-off-by: Simon Glass

binman: Support replacing data in a cbfs

2019-07-29T15:38:06Z

At present binman cannot replace data within a CBFS since it does not allow rewriting of the files in that CBFS. Implement this by using the new WriteData() method to handle the case. Add a header to compressed data so that the amount of compressed data can be determined without reference to the size of the containing entry. This allows the entry to be larger that the contents, without causing errors in decompression. This is necessary to cope with a compressed device tree being updated in such a way that it shrinks after the entry size is already set (an obscure case). It is not used with CBFS since it has its own metadata for this. Increase the number of passes allowed to resolve the position of entries, to handle this case. Add a test for this new logic.

binman: Add a prefix before CBFS hex offsets

2019-07-29T15:38:06Z

Add a 0x prefix to these errors to avoid confusion. Signed-off-by: Simon Glass

binman: Support reading from CBFS entries

2019-07-24T19:54:08Z

CBFS is a bit like a section but with a custom format. Provide the list of entries and the compression type to binman so that it can extract the data from the CBFS, just like any other part of the image. Signed-off-by: Simon Glass

binman: Use the cbfs memlen field only for uncompressed length

2019-07-24T19:54:08Z

The purpose of this badly named field is a bit ambiguous. Adjust the code to use it only to store the uncompressed length of a file, leaving it set to None if there is no compression used. This makes it easy to see if the value in this field is relevant / useful. Also set data_len for compressed fields, since it should be the length of the compressed data, not the uncompressed data.

binman: Provide the actual data address for cbfs files

2019-07-24T19:54:08Z

At present a file with no explicit CBFS offset is placed in the next available location but there is no way to find out where it ended up. Update and rename the get_data() function to provide this information. Signed-off-by: Simon Glass

binman: Add support for fixed-offset files in CBFS

2019-07-24T19:53:46Z

A feature of CBFS is that it allows files to be positioned at particular offset (as with binman in general). This is useful to support execute-in-place (XIP) code, since this may not be relocatable. Add a new cbfs-offset property to control this. Signed-off-by: Simon Glass

binman: Pad empty areas of the CBFS with files

2019-07-24T19:53:46Z

When there is lots of open space in a CBFS it is normally padded with 'empty' files so that sequentially scanning the CBFS can skip from one to the next without a break. Add support for this. Signed-off-by: Simon Glass
