Make the necessary changes so that an ELF kernel can be built. I have successfully built, booted, and run a number of different ELF kernel configurations, including GENERIC. LINT also builds and links cleanly, though I have not tried to boot it. The impact on developers is virtually nil, except for two things. All linker sets that might possibly be present in the kernel must be listed in "sys/i386/i386/setdefs.h". And all C symbols that are also referenced from assembly language code must be listed in "sys/i386/include/asnames.h". It so happens that failure to do these things will have no impact on the a.out kernel. But it will break the build of the ELF kernel. The ELF bootloader works, but it is not ready to commit quite yet.

Put in an initial %VERSREQ field. This will cause existing config(8)'s to give a non-fatal warning about unknown directives, so there is no hurry to rebuild config(8) yet, apart from shutting up the warning.

# Which version of config(8) is required.
Bump the version of config to the latest (3 year old, so upgrade worries are long past). Also remove redundant MACHINE= declarations and passing MACHINE/MACHINE_ARCH to module builds. That's now done in common code.

Change all #includes to follow the current Berkeley style. Some of these ``changes'' are actually not changes at all, but CVS sometimes has trouble telling the difference. This also includes support for second-directory compiles. This is not quite complete yet, as `config' doesn't yet do the right thing. You can still make it work trivially, however, by doing the following: rm /sys/compile mkdir /usr/obj/sys/compile ln -s M-. /sys/compile cd /sys/i386/conf config MYKERNEL cd ../../compile/MYKERNEL ln -s /sys @ rm machine ln -s @/i386/include machine make depend make

Factor the common parts of the Makefile.foo files. This introduces two new files: kern.pre.mk, which contains most of the definitions, and kern.post.mk, which contains most of the rules. I've tested this on i386 and pc98. I have had feedback on the sparc64 port, but no reports from anybody on alpha, ia64 or powerpc. I appologize in advance if I've broken you.

Convert Freescale PowerPC platforms to FDT convention. The following systems are affected: - MPC8555CDS - MPC8572DS This overhaul covers the following major changes: - All integrated peripherals drivers for Freescale MPC85XX SoC, which are currently in the FreeBSD source tree are reworked and adjusted so they derive config data out of the device tree blob (instead of hard coded / tabelarized values). - This includes: LBC, PCI / PCI-Express, I2C, DS1553, OpenPIC, TSEC, SEC, QUICC, UART, CFI. - Thanks to the common FDT infrastrucutre (fdtbus, simplebus) we retire ocpbus(4) driver, which was based on hard-coded config data. Note that world for these platforms has to be built WITH_FDT. Reviewed by: imp Sponsored by: The FreeBSD Foundation

Create a new MACHINE_ARCH for Freescale PowerPC e500v2 Summary: The Freescale e500v2 PowerPC core does not use a standard FPU. Instead, it uses a Signal Processing Engine (SPE)--a DSP-style vector processor unit, which doubles as a FPU. The PowerPC SPE ABI is incompatible with the stock powerpc ABI, so a new MACHINE_ARCH was created to deal with this. Additionaly, the SPE opcodes overlap with Altivec, so these are mutually exclusive. Taking advantage of this fact, a new file, powerpc/booke/spe.c, was created with the same function set as in powerpc/powerpc/altivec.c, so it becomes effectively a drop-in replacement. setjmp/longjmp were modified to save the upper 32-bits of the now-64-bit GPRs (upper 32-bits are only accessible by the SPE). Note: This does _not_ support the SPE in the e500v1, as the e500v1 SPE does not support double-precision floating point. Also, without a new MACHINE_ARCH it would be impossible to provide binary packages which utilize the SPE. Additionally, no work has been done to support ports, work is needed for this. This also means no newer gcc can yet be used. However, gcc's powerpc support has been refactored which would make adding a powerpcspe-freebsd target very easy. Test Plan: This was lightly tested on a RouterBoard RB800 and an AmigaOne A1222 (P1022-based) board, compiled against the new ABI. Base system utilities (/bin/sh, /bin/ls, etc) still function appropriately, the system is able to boot multiuser.

Make 32-bit PowerPC kernels, like 64-bit PowerPC kernels, position-independent executables. The goal here, not yet accomplished, is to let the e500 kernel run under QEMU by setting KERNBASE to something that fits in low memory and then having the kernel relocate itself at runtime.
