annotate packages/kernel/current/tests/kclock0.c @ 1717:faaea4243d52
* cdl/redboot.cdl: Fixed the type of CYGNUM_REDBOOT_FLASH_BASE
* src/flash.c (fis_[un]lock): Fix compiler warnings
* src/flash.c (do_flash_init): Removed the MIPS br0ken condition
which i wrongly added. My problem was actually a / 0. This roundup
is needed otherwise the workspace goes off the end of the RAM.
