x86: quark: Avoid chicken and egg problem

If we convert to use driver model pci on quark, we will encounter
some chicken and egg problems like below:

- To enable PCIe root ports, we need program some registers on the
  message bus via pci bus. With driver model, the first time to
  access pci bus, the pci enumeration process will be triggered.
  But without first enabling PCIe root ports, pci enumeration
  just hangs when scanning PCIe root ports.
- Similar situation happens when trying to access GPIO from the
  PCIe enabling codes, as GPIO requires its block base address
  to be assigned via a pci configuration register in the bridge.

To avoid such dilemma, replace all pci calls in the quark codes
to use the local version which does not go through driver model.

x86: quark: Optimize MRC execution time

Intel Quark SoC has a low end x86 processor with only 400MHz
frequency. Currently it takes about 15 seconds for U-Boot to
boot to shell and the most time consuming part is with MRC,
which is about 12 seconds. MRC programs lots of registers on
the SoC internal message bus indirectly accessed via pci bus.

To speed up the boot, create an optimized version of pci config
read/write dword routines which directly operate on PCI I/O ports.
These two routines are inlined to provide better performance too.
Now it only takes about 3 seconds to finish MRC, which is really
fast (4 times faster than before).

9 years agopinctrl: Add the concept of peripheral IDs
Simon Glass [Sun, 30 Aug 2015 22:55:13 +0000 (16:55 -0600)]
pinctrl: Add the concept of peripheral IDs

My original pinctrl patch operating using a peripheral ID enum. This was
shared between pinmux and clock and provides an easy way to specify a device
that needs to be controlled, even it is does not (yet) have a driver within
driver model.

Masahiro's new simple pinctrl gets around this by providing a
set_state_simple() pinctrl method. By passing a device to that call the
peripheral ID becomes unnecessary. If the driver needs it, it can calculate
it itself and use it internally.

However this does not solve the problem for peripheral clocks. The 'pure'
solution would be to pass a driver to the clock uclass also. But this
requires that all devices should have a driver, and a struct udevide. Also
a key optimisation of the clock uclass is allowing a peripheral clock to
be set even when there is no device for that clock.

There may be a better way to achive the same goal, but for now it seems
expedient to add in peripheral ID to the pinctrl uclass. Two methods are
added - one to get the peripheral ID and one to select it. The existing
set_state_simple() is effectively the union of these.
