[U-Boot] [PATCH v2 0/3] fix apalis_t30 optional pcie operation

[Marcel Ziswiler <marcel@ziswiler.com>]

This series addresses a PCIe reliability issue as observed on Apalis T30
related to a PCIe reset timing violation.

This series depends on Simon's work available at u-boot-dm/master plus
my previous series "move apalis t30/tk1, colibri t20/t30 to livetree"
and "fix apalis-tk1 pcie gigabit ethernet operation".

This series is available at http://git.toradex.com/cgit/u-boot-toradex.git/log/?h=for-next

Changes in v2:
- Leave resp. enable all port 0 pins input drivers as a customer may
  optionally want to use some of those MXM3 pins as inputs as well.
- Stick to struct tegra_pcie_port as suggested by Stephen.
- Introduce proper CONFIG_APALIS_T30_PCIE_EVALBOARD_INIT Kconfig option
  as suggested by Stephen.
- Improved the ifdef vs. if curly braces sequencing as suggested by
  Stephen.
- Keep PCIe port reset status in order to safeguard for future changes
  to the port reset order or even allow for re-initialisation should
  that ever be implemented in the higher levels of the driver model.
