This change adds back support for the resource allocator using
multiple ranges as originally landed in CB:39486(commit hash 3b02006)
and reverted in CB:41413(commit hash 6186cbc). The new resource
allocator can be selected by Kconfig option RESOURCE_ALLOCATOR_V4. It
was identified that there are some AMD chipsets in the tree that do
not really work well with the dynamic resource allocation. Until these
chipsets are fixed, old (v3) and new (v4) of the resource allocator
need to live side-by-side in the tree. There were some other chipsets
in the tree which originally demonstrated problems with the new
resource allocator, but have been since fixed in the tree.
This change picks up the same additions as performed in CB:39486 along
with the following changes:
1. Changes to avoid fixed resources in the entire tree. Use of
search_bus_resources() is replaced with a walk of the entire tree
in avoid_fixed_resources(). This is required to ensure that all fixed
resources added to any device (including domain) are taken into
consideration to avoid overlap during dynamic resource allocation.
2. Changes to set up alignment for memranges when initializing
them. This is done to ensure that the right granularity is used for
IORESOURCE_IO(no special alignment) and IORESOURCE_MEM(4KiB) resource
requests.
3. mark_resource_invalid() is dropped as the resource no longer needs
to be marked in any special way if allocation is not being
done. Instead setting of IORESOURCE_ASSIGNED flag is skipped in this
case.
4. initialize_memranges() is updated to check IORESOURCE_ASSIGNED
instead of base == limit.
Original commit message:
This change updates the resource allocator in coreboot to allow using
multiple ranges for resource allocation rather than restricting
available window to a single base/limit pair. This is done in
preparation to allow 64-bit resource allocation.
Following changes are made as part of this:
a) Resource allocator still makes 2 passes at the entire tree. The
first pass is to gather the resource requirements of each device
under each domain. It walks recursively in DFS fashion to gather the
requirements of the leaf devices and propagates this back up to the
downstream bridges of the domain. Domain is special in the sense that
it has fixed resource ranges. Hence, the resource requirements from
the downstream devices have no effect on the domain resource
windows. This results in domain resource limits being unmodified after
the first pass.
b) Once the requirements for all the devices under the domain are
gathered, resource allocator walks a second time to allocate resources
to downstream devices as per the requirements. Here, instead of
maintaining a single window for allocating resources, it creates a
list of memranges starting with the resource window at domain and then
applying constraints to create holes for any fixed resources. This
ensures that there is no overlap with fixed resources under the
domain.
c) Domain does not differentiate between mem and prefmem. Since they
are allocated space from the same resource window at the domain level,
it considers all resource requests from downstream devices of the
domain independent of the prefetch type.
d) Once resource allocation is done at the domain level, resource
allocator walks down the downstream bridges and continues the same
process until it reaches the leaves. Bridges have separate windows for
mem and prefmem. Hence, unlike domain, the resource allocator at
bridge level ensures that downstream requirements are satisfied by
taking prefetch type into consideration.
e) This whole 2-pass process is performed for every domain in the
system under the assumption that domains do not have overlapping
address spaces.
Noticeable differences from previous resource allocator:
a) Changes in print logs observed due to flows being slightly
different.
b) Base, limit and size of domain resources are no longer updated
based on downstream requirements.
c) Memranges are used instead of a single base/limit pair for
determining resource allocation.
d) Previously, if a resource request did not fit in the available
base/limit window, then the resource would be allocated over DRAM or
any other address space defeating the principle of "no overlap". With
this change, any time a resource cannot fit in the available ranges,
it complains and ensures that the resource is effectively disabled by
setting base same as the limit.
e) Resource allocator no longer looks at multiple links to determine
the right bus for a resource. None of the current boards have multiple
buses under any downstream device of the domain. The only device with
multiple links seems to be the cpu cluster device for some AMD
platforms.

have a zero size. This change removes the setting of resource flags to
IORESOURCE_ASSIGNED when the resource is not really allocated any
space by the allocator. It also drops the setting of base to limit
since that is not required anymore.

This change moves the resource allocator functions out of device.c
and into two separate files:
1. resource_allocator_v3.c: This is the old implementation of
resource allocator that uses a single window for resource
allocation. It is required to support some AMD chipsets that do not
provide an accurate map of allocated resources by the time the
allocator runs. They work fine with the old allocator since it
restricts itself to allocations in a single window at the top of the
4G space.
2. resource_allocator_common.c: This file contains the functions that can
be shared by the old and new resource allocator.
Entry point into the resource allocation is allocate_resources() which
can be implemented by both old and new allocators. This change also
adds a Kconfig option RESOURCE_ALLOCATOR_V3 which enables the old
resource allocator. This config option is enabled by default
currently, but in the following CLs this will be enabled only for the
broken boards.
Reason for this split: Both the old and new resource allocators need
to be retained in the tree until the broken chipsets are fixed.

This change updates find_pci_tolm() to not consider any unassigned
resources. This is achieved by adding the following checks:
1. Call search_bus_resources() with mask set to IORESOURCE_MEM |
IORESOURCE_ASSIGNED.
2. In the callback tolm_test, check that the new resource selected has
a non-zero size.
This change is being made so that the resource allocator does not have
to set the IORESOURCE_ASSIGNED flag for marking a resource as
invalid.

The I/O windows of PCI bridges can be disabled individually by
setting their limit lower than their base. Always do this if a
resource wasn't assigned a value.
