Subject: [PATCH 2/2] fdt: Fix updating the tree at H_CAS
RH-Author: David Gibson <dgibson@redhat.com>
Message-id: <20200107004037.421470-3-dgibson@redhat.com>
Patchwork-id: 93281
O-Subject: [RHEL-AV-8.2.0 SLOF PATCH 2/2] fdt: Fix updating the tree at H_CAS
Bugzilla: 1778704
RH-Acked-by: Laurent Vivier <lvivier@redhat.com>
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.
