c692fbe091 At great personal risk, add a __packed and __aligned(x) define that 
expand to __attribute__((packed)) and __attribute__((aligned(x)))
respectively.  Replace the handful of gcc-ism's that use
__attribute__((aligned(16))) etc around the kernel with __aligned(16).

There are over 400 __attribute__((packed)) to deal with, that can come
later.  I just want to use __packed in new code rather than add more
gcc-ism's.

296c758b66 Disable loader ufs support. It causes the loader to crash on the Itanium2 
box that I have.  We have no EFI disk drivers yet anyway (maybe that is the
problem).

92caa29d8e Add boot_serial and boot_multicons variables to set RB_SERIAL and 
RB_MULTIPLE since this seems to be the easiest way to add these flags
for non-forth loaders etc.

23c12a63cf o Remove namespace pollution from param.h: 
-  Don't include ia64_cpu.h and cpu.h
   -  Guard definitions by  _NO_NAMESPACE_POLLUTION
   -  Move definition of KERNBASE to vmparam.h

o  Move definitions of IA64_RR_{BASE|MASK} to vmparam.h
o  Move definitions of IA64_PHYS_TO_RR{6|7} to vmparam.h

o  While here, remove some left-over Alpha references.

46f8fdc34e Removed now unused INTERNALSTATICLIB. 
INTERNALLIB now implies NOPIC and NOPROFILE.
Removed gratuitous NOMAN.

95cfc25d0d Back out last commit. I expect our bsd.*.mk gods to remove the need for 
defining so many extra things in addition to INTERNALLIB.  We don't like
repetitive C code and we shouldn't for make code either.

3bf8b9cee3 NOPIC, NOPROFILE, NOMAN, and INTERNALSTATICLIB are redundant when using 
INTERNALLIB now.

d1bdfb40fd -ffreestanding is the word. 
(also resort some CFLAGS such that the more "important" value are first so
they are easier to see)

77de753f65 Improve self-relocation: 
o  We don't expect the PLT relocations to follow the .rela section
   anymore. We still assume that PLT relocations are long formed,
o  Document register usage,
o  Improve ILP,
o  Fix the FPTR relocation by creating unique OPDs per function.
   Comparing functions is valid now,
o  The IPLT relocation naturally handles the addend. Deal with it.
   We ignore the addend for FPTR relocations for now. It's not at
   all clear what it means anyway.

Fix ABI misinterpretation:
o  For Elf_Rela relocations, the addend is explicit and should not
   be loaded from the memory address we're relocating. Only do that
   for Elf_Rel relocations (ie the short form).
o  DIR64LSB is not the same as REL64LSB. DIR64LSB applies to a
   symbol (S+A), whereas REL64LSB applies to the base address (BD+A),

c21ab46789 We must not let install(1) strip loader.efi when installing it, or the

402e50591a Do not add the ficl/alpha subdir to the ia64 include path. Try ficl/ia64 
instead.

5459842c5e Do not assume that ${OBJCOPY} variable exists. It was hidden by the 
fact that the 'ia64-make' wrapper explicitly set it.

a6d81d83a2 Fix self hosted loader building. When you use a self configured gcc, it 
detects and uses the gas section merge support.  As a result, a whole bunch
of new sections arrive, including .rodata.str1.8, which was not included
in our custom ldscript.ia64.  The result was a loader binary that EFI
rejected.

While here, collect the loader shell commands linker set and include it
in the data area rather than having its own section.

/boot/loader.efi was the last holdout for having a 100% self built ia64
system.

or may have the wrong header files.

16ed9fd6bb Only install the help file if we can find it. Use ${BASE}.help 
in both the condition and for the install. We expect to find
the help file in ${.OBJDIR}.

cd2c8e3ef6 Pass the address of the bootinfo block to the kernel in register 
r8. Keep it at the hardwired address for now. Bump the version.
 2002-03-30 23:52:34 +00:00
Marcel Moolenaar
c459265de7 Pass the physical address of the bootinfo block to the kernel in 
register r8. We continue to write the bootinfo block at the same
hardwired address, because the kernel still expects it there.
It is expected that future kernels use register r8 to get to the
bootinfo block and don't depend on the hardwired address anymore.

Bump the loader version once again due to the interface change.

a918e110c4 Add a quick and dirty way to determine where we're loaded from. We 
only care if it's network or not at this time. If we're loaded from
the network, we set currdev (=loaddev) so that the kernel is loaded
from the network as well. In all other cases we initialize to disk.
This makes netbooting more convenient and can easily be enhanced to
do more elaborate checking.

4e357dbc58 The EFI loader has been improved a lot since it was first added. 
Most significantly (from an interfacing point of view) is the
support for the FPSWA pointer passing. Even though that was added
4 months ago, it's probably not a bad idea to bump the version
number to reflect this.

ede9f03a1a Fix the beforeinstall target. We install ${PROG}.help if loader.help 
exists, otherwise we install it anyway. I interpret this as a very
high desire to install ${PROG}.help. Alas, ${PROG}.help doesn't exist
at the moment and neither does loader.help, so in practice this just
doesn't work, no matter how you interpret it. The compromise is to
install ${PROG}.help IFF it exists. I realize we lost creativity with
this commit, but style should have been preserved, AFAICT :-)

95c0f344ee o Add -L${DESTDIR}${LIBDIR} on the link line for -lstand. 
o  Add -j .dynstr to objcopy. This makes .efi binaries work
   when built with a 3.x based toolchain.

24ffe931b9 Lookup the EFI_FPSWA driver and pass the interface pointer through to the 
kernel before we call ExitBootServices().  I've typed the definitions
in efifpswa.h from the Intel FPSWA manual (urk).

de76c8189e Remove bootinfo.bi_kernel. It isn't used by the kernel. struct bootinfo 
should go away on ia64, we should be loader metadata based since that is
the only way we can boot (loader, skiload).

4abfff1e2e Call ExitBootServices and disable interrupts before we start hacking 
the VM registers. This ought to make things slightly more reliable here.

7d5af294dc Add the two sections used for PLT entries to the text and sdata sections 
respectively. This makes IPLTLSB relocations work properly (these are
generated for weak symbols, particularly for _longjmp).

88f5f7ac50 Try to get the self-relocator to work with IPLTLSB relocations. Doesn't

6544e18249 Tidy up a little - don't try to print anything or enable interrupts after

3a19b480c8 Add a version of the loader which runs under SKI, the HP ia64 simulator.

faf8077790 Move the first section up one page. The firmware bogusly uses the first 
page of the image to load section headers and if we let the text section
start at zero, it corrupts the section table when its loaded. With this
change, the loader gets as far as the 'ok' prompt.
