[PATCH v2 4/9] tests/acceptance/boot_linux: Expand SD card image to power of 2 |
Date: |
Mon, 13 Jul 2020 20:32:04 +0200 |
In few commits we won't allow SD card images with invalid size
(not aligned to a power of 2). Prepare the tests: add the
pow2ceil() and image_pow2ceil_expand() methods and resize the
images (expanding) of the tests using SD cards.
Signed-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org>

Since v1: Addressed review comments
- truncate -> expand reword (Alistair Francis)
- expand after uncompress (Niek Linnenbank)
