* stand: refactor overlay loading a little bitKyle Evans2019-04-111-1/+7
| | | | | | | | | | | | | | | | | | | | | It was pointed out that manually loading a .dtb to be used rather than relying on platform-specific method for loading .dtb will result in overlays not being applied. This was true because overlay loading was hacked into fdt_platform_load_dtb, rather than done in a way more independent from how the .dtb is loaded. Instead, push overlay loading (for now) out into an fdt_platform_load_overlays. This method easily allows ubldr to pull in any fdt_overlays specified in the ub env, and omits overlay-checking on platforms where they're not tested and/or not desired (e.g. powerpc). If we eventually stop caring about fdt_overlays from ubenv (if we ever cared), this method should get chopped out in favor of just calling fdt_load_dtb_overlays() directly.

* Remove now-unused variable after r328809Kyle Evans2018-02-041-1/+0

* Centralize several variables.Warner Losh2018-02-021-1/+0
| | | | | | | | | | MK_CTF, MK_SSP, MK_PROFILE, NO_PIC, and INTERNALLIB are always the same, so set them in defs.mk. MAN= is common, so set it here too. This removes a lot of boring repetition from the Makefiles that added almost no value. Notes: svn path=/head/; revision=328769
* stand/fdt: Consolidate overlay handling a little furtherKyle Evans2018-01-281-6/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This should have been done as part of r327350, but due to lack of foresight it came later. In the different places we apply overlays, we duplicate the bits that check for fdt_overlays in the environment and supplement that with any other places we need to check for overlays to load. These "other places" will be loader specific and are not candidates for consolidation. Provide an fdt_load_dtb_overlays to capture the common logic, allow passing in an additional list of overlays to be loaded. This additional list of overlays is used in practice for ubldr to pull in any fdt_overlays passed to it from U-Boot environment, but it can be used for any other source of overlays. These additional overlays supplement loader.conf(5) fdt_overlays, rather than replace, so that we're not restricted to specifying overlays in only one place. This is a change from previous behavior where loader.conf(5) supplied fdt_overlays would cause us to ignore U-Boot environment, and this seems nonsensical- user should have sufficient control over both of these aspects, or lack of control for good reasons. A knob could be considered in the future to ignore U-Boot supplied overlays, but the supplemental treatment seems like a good start.

* stand/fdt: Consistently apply fdt_overlaysKyle Evans2017-12-291-6/+14
| | | | | | | | | | | | | | Overlays were previously not applied when U-Boot provides FDT or EFI provides FDT, only when we load FDT from /boot/dtb given name from U-Boot. Make all three paths lead to loading fdt_overlays and applying them, so that fdt_overlays can be expected to Just Work.

This, along with a change to share/mk/bsd.cpu.mk to include -mno-avx2 in CFLAGS_NO_SIMD should fix building for newer machines (eg with CPUTYPE=haswell) where clang was generating avx2 instructions.
