Most of the current implementations for FSP-based platforms
make (sometimes wrong) assumptions how FSP reorders root ports
and what is specified in the devicetree. We don't have to make
assumptions though, and can read the root-port number from the
PCIe link capapilities (LCAP) instead. This is also what we do
in ASL code for years already.
This new implementation acts solely on information read from
the PCI config space. In a first round, we scan all possible
DEVFNs and store which root port has that DEVFN now. Then, we
walk through the devicetree that still only knows devices that
were originally mentioned in `devicetree.cb`, update device
paths and unlink vanished devices.
To be most compatible, we work with the following constraints:
o Use only standard PCI config registers.
o Most notable, don't try to read the registers that
configure the function numbers. FSP has undocumented
ways to block access to non-standard registers.
o Don't make assumptions what function is assigned to
hidden devices.
The following assumptions were made, though:
o The absolute root-port numbering as documented in
datasheets matches what is read from LCAP.
o This numbering doesn't contain any gaps.
o Original root-port function numbers below a PCI
device start at function zero and also don't
contain any gaps.

So, the PCI to PCI bridge specification had a pitfall for us:
Originally, when decoding i/o ports for legacy VGA cycles, bridges
should only consider the 10 least significant bits of the port address.
This means all VGA registers were aliased every 1024 ports!
e.g. 0x3b0 was also decoded as 0x7b0, 0xbb0 etc.
However, it seems, we never reserved the aliased ports, resulting in
silent conflicts we preallocated resources. We neither use much
external VGA nor many i/o ports these days, so nobody noticed.
To avoid this mess, a bridge control bit (VGA16) was introduced in
2003 to enable decoding of 16-bit port addresses. As older systems
seem rather safe and well tested, and newer systems should support
this bit, we'll use it if possible and only warn if not.
With old (AGP era) hardware one will likely encounter a warning like
this:
found VGA at PCI: 06:00.0
A bridge on the path doesn't support 16-bit VGA decoding!
This is not generally fatal, but makes unnoticed resource conflicts
more likely.

When accessing register with multiple bit fields, the common approach is
to use clrsetbits_le32, for example:
clrsetbits(®, (1 << 0) | (0x3 << 1) | (0x7 << 10),
(1 << 0) | (0x1 << 1) | (0x5 << 10));
This hard to maintain because we have to calculate the mask values
manually, make sure the duplicated shift (offset) was set correctly.
And it may be even worse if the value to set will be based on some
runtime values (that many developers will do a if-block with two very
similar argument list), and leaving lots of magic numbers.
We want to encourage developers always giving field names, and have a
better way of setting fields. The proposed utility macros are:
DEFINE_BITFIELD(name, high_bit, low_bit)
EXTRACT_BITFIELD(value, name)
WRITE32_BITFIELDS(addr, name, value, [name2, value2, ...])
READ32_BITFIELD(addr, name)
Where a developer can easily convert from data sheet like
BITS NAME
26:24 SEC_VIO
Into a declaration
DEFINE_BITFIELD(SEC_VIO, 26, 24)
Then, a simple call can set the field as:
WRITE32_BITFIELDS(®, SEC_VIO, 2);
That is much easier to understand than
clrsetbits_le32(®, 0x7 << 24, 0x2 << 24);
And to extract the value:
READ32_BITFIELD(®, SEC_VIO)
That is equivalent to:
(read32(®) & 0x3) >> 24

Many peripheral drivers across different SoCs regularly face the same
task of piping a transfer buffer into (or reading it out of) a 32-bit
FIFO register. Sometimes it's just one register, sometimes a whole array
of registers. Sometimes you actually transfer 4 bytes per register
read/write, sometimes only 2 (or even 1). Sometimes writes need to be
prefixed with one or two command bytes which makes the actual payload
buffer "misaligned" in relation to the FIFO and requires a bunch of
tricky bit packing logic to get right. Most of the times transfer
lengths are not guaranteed to be divisible by 4, which also requires a
bunch of logic to treat the potential unaligned end of the transfer
correctly.
We have a dozen different implementations of this same pattern across
coreboot. This patch introduces a new family of helper functions that
aims to solve all these use cases once and for all (*fingers crossed*).

The effect of pointer aliasing on writes is that any data on CPU
registers that has been resolved from (non-const and non-volatile)
memory objects has to be discarded and resolved. In other words, the
compiler assumes that a pointer that does not have an absolute value
at build-time, and is of type 'void *' or 'char *', may write over
any memory object.
Using a unique datatype for MMIO writes makes the pointer to _not_
qualify for pointer aliasing with any other objects in memory. This
avoid constantly resolving the PCI MMCONF address, which is a derived
value from a 'struct device *'.

Drop the bus parameter, we do not use it.
It would still be possible to do per-bus selection
by evaluating the bus number, but currently we do
not have need for that either.

Having different signatures for the PCI config accessors
prevents them from having the same name in different
stages.
For now, work around this using __SIMPLE_DEVICE__.

These are defined for __SIMPLE_DEVICE__ when PCI
enumeration has not happened yet. These should not
really try to probe devices other than those on bus 0.
It's hard to track but there maybe cases of southbridge
being located on bus 2 and available for configuration, so
I rather leave the code unchanged. Just move these out of
arch/io.h because they cause build failures if one attempts
to include <arch/pci_ops.h> before <arch/io.h>.
There are two direct copies for ROMCC bootblocks to
avoid inlining them elsewhere.

Semantics of dev_find_slot() are ill in the sense that
it only works after device enumeration has completed in
ramstage. Plan is to declare it as deprecated.
Introduce pcidev_on_root() and pcidev_path_on_root()
functions to replace cases where this was called with
static argument bus == 0. New implementation only walks
the root bus of the PCI tree, while old one walked
the entire linked list of devices.
Introduce pcidev_path_behind() to replace cases where
argument bus != 0. The required parent node is typically
one of the PCIe root functions that you locate using
pcidev_on_root() above.
New forms are safe to use with early devicetree and
before PCI bus numbers have been assigned.

The feature is used to enable PCI MMIO accesses behind
PCIe links (or bridges) before PCI enumeration has been
completed.
Add the feature for bootblock, verstage and postcar, it
is required with add-on PCIe serial cards for early
console output. It's up to the board specific code to
configure PCIe root port prior to calling console_init()
for this to work.
Remove feature from ramstage, it bypasses any resource
allocations and bus number assignments.
For the moment PCI configuration support before ramstage
is available only on ARCH_X86.
Also switch from device_t to pci_devfn_t.

The H81 chipset is the only non-LP Lynx Point chipset with 6 PCIe root
ports, all others have 8 [1]. The existing PCIe code assumed that all
non-LP chipsets had 8 root ports, which meant that port 6 would not be
considered the last root port on H81, so `root_port_commit_config()`
would not run. Ultimately, while PCIe still worked on H81, all the root
ports would remain enabled, even if disabled in the devicetree.
Also, remove `PCI_DEVICE_ID_INTEL_LYNXPOINT_MOB_DESK_{MIN,MAX}`, as they
are unused, and the MAX constant is incorrect.
Interestingly, this fixes an issue where GRUB is unable to halt the
system.
Tested on an ASRock H81M-HDS. The root ports disabled in the devicetree
do indeed end up disabled.
