xtensa: enable building of all dtbs (99085704) · Commits · 戴 / test

Enable building all dtb files when CONFIG_OF_ALL_DTBS is enabled. The dtbs are not really dependent on a platform being enabled or any other kernel config, so for testing coverage it is convenient to build all of the dtbs. This builds all dts files in the tree, not just targets listed. Signed-off-by:
