Use the linker table mechanism to enumerate the underlying PCI I/O
APIs, to allow PCIAPI_CLOUD to become architecture-independent code.

[pci] Allow PCI configuration space access mechanism to vary by range2025-11-24T19:10:49+00:00Michael Brown2025-11-24T14:44:53+00:00urn:sha1:0cf2f8028c5468303f6f8ec7f639fdfd31d70e74
On some systems (observed on an AWS EC2 c7a.medium instance in
eu-west-2), there is no single PCI configuration space access
mechanism that covers all PCI devices. For example: the ECAM may
provide access only to bus 01 and above, with type 1 accesses required
to access bus 00.
Allow the choice of PCI configuration space access mechanism to be
made on a per-range basis, rather than being made just once in an
initialisation function.

[memmap] Rename addr/last fields to min/max for clarity2025-05-23T15:55:42+00:00Michael Brown2025-05-23T15:55:42+00:00urn:sha1:036e43334ad94125dfe212480957fd397e51a053
Use the terminology "min" and "max" for addresses covered by a memory
region descriptor, since this is sufficiently intuitive to generally
not require further explanation.

[uheap] Expose external heap region directly2025-05-22T15:28:15+00:00Michael Brown2025-05-22T10:58:11+00:00urn:sha1:11e01f0652daaf198317e2e13c8bb1d19f664ce9
We currently rely on implicit detection of the external heap region.
The INT 15 memory map mangler relies on examining the corresponding
in-use memory region, and the initrd reshuffler relies on performing a
separate detection of the largest free memory block after startup has
completed.
Replace these with explicit public symbols to describe the external
heap region.

[memmap] Use memmap_dump_all() to dump debug memory maps2025-05-16T15:18:36+00:00Michael Brown2025-05-15T16:09:35+00:00urn:sha1:a353e70800e5416c94af42f9abbf0a3b0f8564f5
There are several places where get_memmap() is called solely to
produce debug output. Replace these with calls to memmap_dump_all()
(which will be a no-op unless debugging is enabled).

[bios] Describe umalloc() heap as an in-use memory area2025-05-16T15:18:36+00:00Michael Brown2025-05-15T14:35:27+00:00urn:sha1:3812860e39faafa56d4b833030b1a8427488bd16
Use the concept of an in-use memory region defined as part of the
system memory map API to describe the umalloc() heap.
