* [PowerPC64LE] Set up powerpc.powerpc64le architectureBrandon Bergren2020-09-221-4/+4
| | | | | | | | | | | | | | | | | | This is the initial set up for PowerPC64LE. The current plan is for this arch to remain experimental for FreeBSD 13.

* [PowerPC] Remove obsolete MK_LOADER_FORCE_LEBrandon Bergren2020-09-151-6/+0
| | | | | | | | | | | | | | | | | | | | | | | | | In D12421, the ability to compile stand/ in little-endian was added, with the intention to extend loader.kboot to run in Petitboot. However, no further work was done, as the kernel then gained self-execution capabilities as Petitboot was taught to load FreeBSD kernels directly. The FreeBSD installer on powerpc64 (on POWER8 and POWER9) uses /boot/etc/kboot.conf instead of loader. As this option does nothing but cause stand/ to be miscompiled and actively causes confusion, remove it. (I have a functioning petitboot loader in my local tree, however, it turned out to be quite inconvient to use due to the current petitboot plugin design so I put it on hold.)

* Create CFLAGS_EARLY.file for boot loader.Warner Losh2020-08-281-0/+5
| | | | | | | | | | | | | | | | | | Some external code requires a specific set of include paths to work properly since it emulates the typical environment the code is used in. Enable this by creating a CFLAGS_EARLY.file variable that can be used to build this stack. Otherwise the include stack we build for stand programs may get in the way. Code that uses this feature has to tolerate the normal stack of inclues being last on the list (and presumably unused), though. Generally, it it should only be used for the specific include directories. Defines and that sort of thing should be done in the normal CFLAGS variable. There is a global CFLAGS_EARY hook as well for everything in a Makefile. Notes: svn path=/head/; revision=364924

* Really fix cleandir after r362973Mitchell Horne2020-07-141-1/+2
| | | | | | | | | | | | | | | | | | I made an attempt to fix this in r362978, but all it really did was confine the issue to the $MACHINE_CPUARCH == "riscv" case. The real problem is that LINKER_FEATURES is not defined here, so bsd.linker.mk needs to be included. This error with cleandir only occurs when META_MODE is disabled, which explains why it was missed by both CI and myself. Note that this effectively reverts r362978.

| | | | | | | | | | | | | | | | | | | | | This implementation doesn't have any major deviations from the other EFI ports. I've copied the boilerplate from arm and arm64. I've tested this with the following boot flows: OpenSBI (M-mode) -> u-boot (S-mode) -> loader.efi -> FreeBSD OpenSBI (M-mode) -> u-boot (S-mode) -> boot1.efi -> loader.efi -> FreeBSD Due to the way that u-boot handles secondary CPUs, OpenSBI >= v0.7 is required, as the HSM extension is needed to bring them up explicitly. Because of this, using BBL as the SBI implementation will not be possible. Additionally, there are a few recent u-boot changes that are required as well, all of which will be present in the upcoming v2020.07 release.

| | | | | | | | | | | | | | | | | | | | | | | Summary: This patch is to support ongoing work for replacing "GCC/BFD" by "CLANG/LLD" on target PowerPC64 [1], by proposing a way to specify and/or locate a secondary ld.bfd linker. This is necessary as LLD currently doesn't support PowerPC 32 bits, so we keep using BFD for the 32 bit stuff on PowePC64(LIB32 compatibility and STAND/slof/loader.) - creates LD_BFD variable pointing to ld.bfd - use LD_BFD as linker for LIB32/compat - Default behavior for other platforms aren't changed.

* Add flua to the base system, install to /usr/libexecKyle Evans2019-11-181-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | FreeBSDlua ("flua") is a FreeBSD-private lua, flavored with whatever extensions we need for base system operations. We currently support a subset of lfs and lposix that are used in the rewrite of makesyscall.sh into lua, added in r354786. flua is intentionally written such that one can install standard lua and some set of lua modules from ports and achieve the same effect. linit_flua is a copy of linit.c from contrib/lua with lfs and lposix added in. This is similar to what we do in stand/. linit.c has been renamed to make it clear that this has flua-specific bits. luaconf has been slightly obfuscated to make extensions more difficult. Part of the problem is that flua is already hard enough to use as a bootstrap tool because it's not in PATH- attempting to do extension loading would require a special bootstrap version of flua with paths changed to protect the innocent. src.lua.mk has been added to make it easy for in-tree stuff to find flua, whether it's bootstrap-flua or relying on PATH frobbing by Makefile.inc1.

* Extend loader(8) geli support to all architectures and all disk-like devices.Ian Lepore2018-07-131-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | This moves the bulk of the geli support from lib386/biosdisk.c into a new geli/gelidev.c which implements a devsw-type device whose dv_strategy() function handles geli decryption. Support for all arches comes from moving the taste-and-attach code to the devopen() function in libsa. After opening any DEVT_DISK device, devopen() calls the new function geli_probe_and_attach(), which will "attach" the geli code to the open_file struct by creating a geli_devdesc instance to replace the disk_devdesc instance in the open_file. That routes all IO for the device through the geli code. A new public geli_add_key() function is added, to allow arch/vendor-specific code to add keys obtained from custom hardware or other sources. With these changes, geli support will be compiled into all variations of loader(8) on all arches because the default is WITH_LOADER_GELI.
