sysutils/opensbi: fix build with clang 17

Building sysutils/opensbi with clang 17 results in the following errors:

  clang: error: unsupported option '-mno-unaligned-access' for target
'riscv64-unknown-elf'
  clang: error: unsupported option '-mno-unaligned-access' for target
'riscv64-unknown-elf'
  [... many more times...]

The target-specific option -mno-unaligned-access (which is emitted from
the compiler driver when -mstrict-align is used) did not do anything for
riscv64, but clang 17 is now more strict about reporting unsupported
options. Remove the -mstrict-align option from the Makefile's CFLAGS and
ASFLAGS to fix it.

sysutils/opensbi: update to version 1.2

With this version, stop providing the library and header files
altogether. I do not think they are useful at this time.

Bump associate u-boot port revisions.

Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Approved by:		portmgr (tcberner)

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

sysutils/opensbi: update to version v1.0

As the fu540 platform has been removed with this version, fall back to
building the generic platform only. Keep the platform logic around in
the Makefile in case we need it in the future.

Switch to building with base system clang+binutils.

Bump the PORTREVISION for sysutils/u-boot-sifive-fu540.

One more small cleanup, forgotten yesterday.

Remove # $FreeBSD$ from Makefiles.

sysutils/opensbi: update to v0.9

This change adds a patch to disable the PMP for the sifive/fu540 target,
which is a workaround to a PMP errata in the chip. The OpenSBI update
itself is quite minor.

Bump the dependent port, sysutils/u-boot-sifive-fu540.

sysutils/opensbi: update to v0.8

This brings some restructuring to the installation paths. Firmware
files are still stored under /usr/local/share, but with the new prefix
allowing for multiple ABIs to be installed (e.g. opensbi/lp64/qemu/virt).
Libraries have been moved to /usr/local/lib64.

A new "generic" platform has been added, which will produce firmware
binaries capable of running on several platforms. The qemu/virt and
spike platforms have been removed as a result.

Additionally, the fw_payload.[bin|elf] files will no longer be
installed. These are compiled with the test payload and therefore don't
offer much use as part of this port.

sysutils/opensbi: update to version 0.6

This update adds a new default option: SPIKE. This builds support for the Spike
platform. Also, the toolchain dependency has been switched from riscv64-gcc to
riscv64-none-elf-gcc.

This release has:

Relocation lottery in reference firmwares
Preferred boot HART field in fw_dynamic_info
Platform specific optional way to specify MISA
Hypervisor v0.5 specification support
SBI v0.2 TIME extension
SBI v0.2 IPI extension
SBI v0.2 RFENCE extension

New port: sysutils/opensbi: OpenSBI, a RISC-V bootloader and firmware

OpenSBI is a RISC-V bootloader and set of firmware libraries that
implement the RISC-V Supervisor Binary Interface (SBI) required for
supervisor targets, such as the FreeBSD kernel.

This port installs the OpenSBI libraries that can be used for
development of custom firmwares, as well as the firmware files for the
QEMU virt and SiFive U540 platforms.
