The P2SB device is device 0xd and function 0. If hidden that
causes the latter pci devices on function >= 1 to not be probed
in the kernel. This is also a problem for coreboot if the P2SB
device is hidden by FSP. That means the coreboot driver won't
be ran. Therefore, provide hide and unhide functions for the
P2SB device.
The other quirk is to allow the GPIO devices to work correctly.
Those devices are ACPI devices. However, their resources are
sub-regions within the P2SB BAR. Sadly, linux doesn't handle
ACPI devices being children of PCI devices. This leads to resource
conflict errors when the P2SB device is visible. For the
time being keep the P2SB device hidden, but also ensure the

of that is the PMC and SPI device are no longer probed by the

The timer emulation works by deriving a frequency based off the

With that knowledge update the code to let the compiler perform

Instead of using platform_prog_run() for flushing programs
from L1D to L2 for code coherency purposes use arch_segment_loaded()
instead as that it's primary purpose. The arch_segment_loaded()
is called within the infrastructure at the appropriate places when
loading programs. Therefore use that to perform the L1D flush
instead of when something is just about to run.

The flush L1D to L2 operation was only being used when loading
romstage from bootblock. However, when the FSP-M component is
loaded no code coherency actions are taken. I suspect this is
because the FSP-M component is larger than the 24KiB L1D and
the entry point is early in the image. Thus, when loading
the FSP-M component the earlier part of the image is flushed
out to L2 in the process of loading the latter part of the
component. Also, once verstage is introduced the same
code coherency actions need to be taken as well. Therefore,
position the apollolake code to handle all these cases.

The current Apollolake flow has its code executing out of
cache-as-ram for the pre-DRAM stages. This is different from
past platforms where they were just executing-in-place against
the memory-mapped SPI flash boot media. The implication is
that when cache-as-ram needs to be torn down one needs to be
executing out of DRAM since the act of cache-as-ram going
away means the code disappears out from under the processor.
Therefore load and use the postcar infrastructure to bootstrap
this process for tearing down cache-as-ram and subsequently
loading ramstage.
