The code for printing information about FITs is fairly old and not that
easy to maintain. It also lacks tests.

This series adds some tests, moves the code into its own file and then
adds a series of helpers to deal with the intricacies of printing each
item.

This provides a binary-size reduction of about 320 bytes on aarch64.


Simon Glass (30):
  docs: Merge .claude/README.md into CLAUDE.md
  tools: Fix debug() to avoid unused-variable warnings
  test: Increase expect_str/actual_str buffer size
  fit: Remove unused len parameter from fit_get_name()
  test: Add a test for FIT image printing
  test: Add signature-testing to the FIT-printing test
  test: fit: Test printing a FIT with multiple FDTs
  test: fit: Test the remaining features and edge cases
  test: fit: Add test for missing FIT description
  test: fit: Add pytest for mkimage output
  fit: Refactor fit_print_contents() to use new fit_print()
  fit: Move printing code to its own file
  fit: Drop showing an unused 'required' property
  fit: Add a context struct for FIT-printing
  fit: Put the indent string into print context
  fit: Create some helpers for printing
