Add missing support for specifying I/O control flags during core reset, and resolve a number of siba(4)-specific reset issues: - Add missing check for target reject flags in siba_is_hw_suspended(). - Remove incorrect wait on SIBA_TMH_BUSY when modifying any target state register; this should only be done when waiting for initiated transactions to clear. - Add missing wait on SIBA_IM_BY when asserting SIBA_IM_RJ. - Overwrite any previously set SIBA_TML_REJ flag when bringing the core out of reset. This fixes a lockup that occured when we brought up a core (after reboot) that had previously been placed into RESET by siba_bwn(4).

For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information).
The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7) and https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables.
The buildkernel and installkernel targets build and install
the kernel and the modules (see below). Please see the top of
the Makefile in this directory for more information on the
standard build targets and compile-time flags.
Building a kernel is a somewhat more involved process. See build(7), config(8), and https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information.
Note: If you want to build and install the kernel with the
buildkernel and installkernel targets, you might need to build
world before. More information is available in the handbook.
The kernel configuration files reside in the sys/<arch>/conf
sub-directory. GENERIC is the default configuration used in release builds.
NOTES contains entries and documentation for all possible
