This image combines the SPL with the i.MX header and U-Boot. This is a
convenient way of having a single image to program on some boot devices.
The i.MX header has to be added to the SPL before appending U-Boot, so that the
boot ROM loads only the SPL.

Changes in v10: None
Changes in v9: None
Changes in v8:
- Use CONFIG_SPL_PAD_TO instead of CONFIG_SPL_MAX_SIZE for padding, which
allows to pad the SPL after adding the i.MX header, which may save time when
the boot ROM loads the SPL.
- Add /u-boot-with-spl.imx to .gitignore.
Changes in v7:
- New patch.
