In principle it is possible to fill in such symbols in U-Boot proper, as well. +Map files +--------- + +The -m option causes binman to output a .map file for each image that it +generates. This shows the position and size of each entry. For example: + + Position Size Name + 00000000 00000010 section@0 + 00000000 00000004 u-boot + 00000010 00000010 section@1 + 00000000 00000004 u-boot + +This shows a hierarchical image with two sections, each with a single entry. The +positions of the sections are absolute hex byte offsets within the image. The +positions of the entries are relative to their respective sections. The size of +each entry is also shown, in bytes (hex). The indentation shows the entries +nested inside their sections. + + Code coverage ------------- @@ -628,7 +647,6 @@ Some ideas: 'Access to binman entry positions at run time' above - Use of-platdata to make the information available to code that is unable to use device tree (such as a very small SPL image) -- Write an image map to a text file - Allow easy building of images by specifying just the board name - Produce a full Python binding for libfdt (for upstream) - Add an option to decode an image into the constituent binaries |
