We expect the firmware to load the external payload at the second
megapage, and that there is space to put the filtered FDT at 0x2200000
past the start of memory. With a default MEM_START of 0x80000000, this
matches the standard OpenSBI values for FW_JUMP_ADDR and
FW_JUMP_FDT_ADDR of 0x80400000/0x80200000 (RV32/RV64) and 0x82200000
respectively, so payloads linked for one should work with the other.
* Added --with-abi configure option
* Revised to preserve original semantics when user specifies --with-arch but not --with-abi or when the user specifies --with-arch but not --host.
For systems where physical memory is mapped to a start address
different from 0x80000000, allow the default to be overridden
using the --with-mem-start argument to the configure script.

bbl.bin is necessary for booting on hardware and is created by
a simple objcopy line. It's much more convienent for riscv-pk to
create this file then to expect the user to know to do it or
to dig through the SDK's makefile to learn that it's required.

The riscv compiler available in Ubuntu enables stack protection and
FORTIFY source by default which breaks the build. Adding
-fno-stack-protector and -U_FORTIFY_SOURCE to the tool flags
fixes this without any side effects.
The compiler available in debian do not have these protections enabled
and work with or without the extra flag.
Fixes: #105

For now, we always compile files with -mabi option by using
soft-fp ABI. But there are some files use the header which in
toolchain, like unistd.h, stdint.h and so on. Finally, these
header files include other header files which existing depend
on ABI such as stubs-lp64.h or stubs-lp64d.h. So it causes the
header file not found when using the double-float toolchain with
soft-float ABI.
Fix up by compiling files with -march and -mabi options only if
there is specifying the --with-arch option at configure time.
If use the --with-arch option at configure time, that means your
toolchain has multi-lib support, so always building riscv-pk
by soft-float ABI is fine. Otherwise, we don't compile files with
specifying march and mabi options explicitly
Get rid of the --enable-32bit option and switch to use --with-arch,
which is more standard because it matches the GCC build.
If --with-arch is not specified, it defaults to whatever the
compiler's default is.
The --with-abi is not necessary for this project.
Unconditionally compile it with a no-float ABI.
DESTDIR is a common make idiom. As per the GNU coding standards
https://www.gnu.org/prep/standards/html_node/DESTDIR.html
"DESTDIR is a variable prepended to each installed target file, like
this:
$(INSTALL_PROGRAM) foo $(DESTDIR)$(bindir)/foo
$(INSTALL_DATA) libfoo.a $(DESTDIR)$(libdir)/libfoo.a
The DESTDIR variable is specified by the user on the make command
line as an absolute file name. For example:
make DESTDIR=/tmp/stage install
DESTDIR should be supported only in the install* and uninstall*
targets, as those are the only targets where it is useful.
If your installation step would normally install /usr/local/bin/foo
and /usr/local/lib/libfoo.a, then an installation invoked as in the
example above would install /tmp/stage/usr/local/bin/foo and
/tmp/stage/usr/local/lib/libfoo.a instead."
The current Makefile.in uses DESTDIR, but has a slightly non-standard
behavior: the target install location doesn't include "$prefix". This
breaks package managers, because stuff ends up getting installed to
the wrong location.
Unfortunately the only way I can think of to fix this involves
silently changing the behavior of DESTDIR. Hopefully nobody is using
it...?
[port of 8a2088b59162fe16c16d26ddc1cfcaaaa8c4156f in riscv-fesvr]
Now uses a modified MCPPBS. Add --host=riscv to configure path.
Front-end server now just searches PATH for riscv-pk, so just install the pk
to somewhere in your path.
