[U-Boot] [PATCH v6 0/6] fix apalis-tk1 pcie gigabit ethernet operation

[Marcel Ziswiler]

This series addresses a gigabit Ethernet reliability issue as observed
on Apalis TK1 related to a PCIe reset timing violation.

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

Changes in v6:
- Use macro AS3722_LDO_CONTROL0_MAX_INDEX instead of the hard-coded
  number 7 in LDO index check as suggested by Jaehoon Chung.
- Updated to latest SPDX style.

Changes in v5:
- Add Stephen's acked-by.
- Updated copyright period to 2016-2018.
- Changed error() to pr_err().
- Added a blank line after declarations as warned by patman.
- Rebased and resend as series so far never got applied!

Changes in v4:
- Revert previously missed (struct tegra_pcie_port *) casts as reported
  by Stephen.

Changes in v3:
- Stick to struct tegra_pcie_port as suggested by Stephen.
- Stick to struct tegra_pcie_port as suggested by Stephen.
- Introduce proper CONFIG_APALIS_TK1_PCIE_EVALBOARD_INIT Kconfig option
  as suggested by Stephen.

Changes in v2:
- Add Simon's reviewed-by.
- New bug fix.
- Incorporate Stephen's review feedback by introducing a
  tegra_pcie_port_index_of_port() function as well as a board-specific
  reset override function.
- Add Simon's reviewed-by.
