[PATCH u-boot-marvell 0/9] mvebu: Move PCIe code from serdes to PCIe driver

This patch series removes gdsys's board_pex_config() function by
converting it to spl_board_init(), adds a new mvebu-reset driver for
enabling / disabling PCIe ports and finally moves PCIe code from serdes
driver to pci_mvebu.c driver.
After all these changes, PCIe link is not initialized in serdes code
anymore, but in pci_mvebu.c driver with help of mvebu-reset driver.
I'm not sure if change for gdsys board is correct, so if somebody has
this board, please test it.
I tested this change on A385 board Turris Omnia and I verified that PCIe
links are really enabled by pci_mvebu.c driver and not before.
This patch series is based on u-boot-marvell/next branch.
Pali Rohár (9):
arm: mvebu: Convert board_pex_config() to CONFIG_SPL_BOARD_INIT
board: gdsys: a38x: Enable PCIe link 2 in spl_board_init()
pci: pci_mvebu: Fix PCIe MEM and IO resources assignment and mbus
mapping
pci: pci_mvebu: Inline mvebu_pcie_port_parse_dt() function
pci: pci_mvebu: Remove dependency on SOC_REGS_PHY_BASE macro
pci: pci_mvebu: Split initialization of PCIe ports into 3 phases
pci: pci_mvebu: Wait 100ms for Link Up in mvebu_pcie_probe()
arm: mvebu: Implement simple mvebu-reset driver for enabling/disabling
PCIe ports
arm: mvebu: a38x: serdes: Move non-serdes PCIe code to pci_mvebu.c
