Whitespace: Automated whitespace fixes (large commit) Apply the pre-commit hook whitespace fixes to all files in the repo. (Line endings, blank lines at end of file, trailing whitespace) 2020-11-10 07:40:01 +00:00			`set(srcs`
newlib: move abort to newlib 2020-02-02 15:18:29 +00:00			`"abort.c"`
cmake: some formatting fixes Do not include bootloader in flash target when secure boot is enabled. Emit signing warning on all cases where signed apps are enabled (secure boot and signed images) Follow convention of capital letters for SECURE_BOOT_SIGNING_KEY variable, since it is relevant to other components, not just bootloader. Pass signing key and verification key via config, not requiring bootloader to know parent app dir. Misc. variables name corrections 2019-06-21 06:29:32 +00:00			`"heap.c"`
