From: Thomas Huth <thuth@redhat.com>
When compiling with a very recent toolchain, I get these warnings:
../../llfw/boot_abort.S: Assembler messages:
../../llfw/boot_abort.S:76: Warning: invalid register expression
and:
stage2_head.S: Assembler messages:
stage2_head.S:57: Warning: invalid register expression
The first one is using the wrong opcode, we should use "and" instead of
"andi" here. The second one is using a register instead of a constant
for load-immediate, which is non-sense, too. Fix it to use the right
constant instead.

We can select the console output, but it does not really work
Implement term-io-emit, as we have term-io-key to really
send characters to the output selected by stdout.
Resolve xt and ihandle in the output command.
Use them in the new term-io-emit function.

Bugzilla: 1655649

RH-Acked-by: David Gibson <dgibson@redhat.com>
RH-Acked-by: Serhii Popovych <spopovyc@redhat.com>
QEMU supports up the 64 SCSI IDs on the vscsi "bus", see the string
"max_target = 63" in the source file hw/scsi/spapr_vscsi.c of QEMU.
However, SLOF currently only checks the first 9 IDs on the vscsi adaptor,
so when you try to boot from a CD-ROM like this, the boot fails:
qemu-system-ppc64 ... -device spapr-vscsi,id=scsi0,reg=0x2000 \
-drive file=/path/to/cdrom.iso,format=raw,if=none,id=dr1,readonly=on \
-device scsi-cd,bus=scsi0.0,channel=0,scsi-id=63,lun=1,drive=dr1,id=scd1
Thus let's change the amount of IDs that we scan in SLOF to 64, too, to
match the ID range that QEMU provides.

Bugzilla: 1778704

RH-Acked-by: Thomas Huth <thuth@redhat.com>
RH-Acked-by: Miroslav Rezanina <mrezanin@redhat.com>
From: Alexey Kardashevskiy <aik@ozlabs.ru>
The previous approach to merge the QEMU FDT into the existing tree and
then patch it turned to be broken as we patch properties based on their
names only so we patch not just what QEMU provides (which was
the intention) but also all properties SLOF created. This breaks one of
them - "interrupt-map" - it is created by QEMU for a PHB but SLOF creates
it for PCI bridges and since they have different sizes, patching phandles
at fixed offset fails.
Rather than skipping certain nodes in the SLOF tree, this uses different
approach: now we read the QEMU FDT in 3 passes:
1. find all phandle/linux-phandle properties and store these in the SLOF
internal tree to allow phandle->node lookup later;
2. walk through all FDT properties, patch them if needed using
phandles from the SLOF tree and save patched values in SLOF properties;
3. delete phandle/linux-phandle properties created in 1. This is safe
as SLOF does not create these properties anyway.
Fixes: 44d06f9e68cf ("fdt: Update phandles after H_CAS")

fdt-fix-cas-node returns the end address after it's finished which
the caller (ibm,client-architecture-support) does not use or drop.
This renames fdt-fix-cas-node to (fdt-fix-cas-node) and adds a wrapper
on top of that which does the drop. This will be used later for 2-pass
tree patching.
While at this, exit the function if memory allocation failed.

From: Thomas Huth <thuth@redhat.com>
When compiling SLOF with GCC 8.1, I currently get a lot of these errors:
ERROR: Unhandled relocation (A) type 26
Type 26 is the "relative 32-bit" relocation. We can simply ignore it
(like the other relative relocations - REL14, REL24 and REL64) to
shut up these error messages.

them is:

copying 8 bytes from a string of the same length [-Wstringop-truncation]

The only missing parts were to manage the transfer direction in
do-bulk-command and to copy the data to the buffer before the
write operation.
This is needed as GRUB2 wants to write the grubenv file at start
and hangs because the data are not provided to the disk controller.
I've checked the file is correctly modified by modifying an environment
variable in GRUB2 with "set saved_entry=2" then "save_env saved_entry"
and checking the result in linux with "grub2-editenv list".
Fixes: Fixes: a0b96fe66fcd991b407c1d67ca842921e477a6fd
(Provide "write" function in the disk-label package)
