* fixed inline functions for modern C standart * more stack for application * added library * init fatfs library * fatfs example application * Merge with current master * fix typo and delete old files * cmsis os 2 reentrance fix * Reworked dependency wait to support multiple dependency * Build FatFS on local target, syscall.c is target-specific. * run local target ok * testcase for fatfs Co-authored-by: aanper <mail@s3f.ru>
