particular interest in (and support for) SRI International and the University of Cambridge's BERI FPGA soft-core processor. This includes micro device drivers for the Altera JTAG UART console, memory-mapped flash, and the Altera SD Card IP core in both boot2 and loader. boot2 can be written to the on-board Intel StrataFlash on the DE4 board, and loader can be placed in StrataFlash or the SD Card. Plenty of XXX comments, but works quite well locally in practice and I am using it daily. Although I had originally ported the ARM version of boot2, the current version is x86-derived as that proved more feature-complete. As we don't currently use partitions on our flash disks, support for that has been commented out relative to x86, but would be easy to add back. FDT support has not yet been hooked up, although some skeleton parts have been put in place for that. This may well be a useful starting point for ports to other 32-bit and 64-bit MIPS-ISA systems. This merge is synchronised to CheriBSD github commit e41d74fd719525d4dd7a7ee499114679165eeaf6, but with some additions of $FreeBSD. MFC after: 3 weeks Sponsored by: DARPA, AFRAL
This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ 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, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. The ``world'' target should only be used in cases where the source tree has not changed from the currently running version. See: http://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, documentation for which can be found at: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html And in the config(8) man page. 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 sample kernel configuration files reside in the sys/<arch>/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
