d06ba5cc71 arm: mvebu: dts: armada-375.dtsi: Add timer0 & timer1
Add the DT bindings / descriptions for timer0 & timer1, exactly as done
in mainline Linux.

5d4d1212f7 arm: mvebu: Remove redundant u-boot, dm-pre-reloc from all 32-bit Armada SoCs
Replace it by including of mvebu-u-boot.dtsi file. When board does not use
-u-boot.dtsi then mvebu-u-boot.dtsi is included automatically by makefile
scripts/Makefile.lib.

204b8707cd arm: mvebu: Fix compatible string for nand controller
Linux kernel uses compatible string "marvell,armada370-nand-controller" for
nand controllers on Armada 370/XP/38x. U-Boot currently uses mix of
"marvell,armada370-nand" and "marvell,mvebu-pxa3xx-nand".

So unify it and use just Linux kernel compatible string.

94c30f9c8f arm: mvebu: a38x: serdes: Move non-serdes PCIe code to pci_mvebu.c
As explained in commit 3bedbcc3aa ("arm: mvebu: a38x: serdes: Don't
overwrite read-only SAR PCIe registers") it is required to set Maximum Link
Width bits of PCIe Root Port Link Capabilities Register depending of number
of used serdes lanes. As this register is part of PCIe address space and
not serdes address space, move it into pci_mvebu.c driver.

Read number of PCIe lanes from DT property "num-lanes" which is used also
by other PCIe controller drivers in Linux kernel. If this property is
absent then it defaults to 1. This property needs to be set to 4 for every
mvebu board which use PEX_ROOT_COMPLEX_X4 or PEX_BUS_MODE_X4.

Enabling of PCIe port needs to be done afer all registers in PCIe address
space are properly configure. For this purpose use new mvebu-reset driver
(part of system-controller) and remove this code from serdes code.

Because some PCIe ports cannot be enabled individually, it is required to
first setup all PCIe ports and then enable them.

This change contains also all required "num-lanes" and "resets" DTS
properties, to make pci_mvebu.c driver work correctly.

35e29e89a3 arm: mvebu: Implement simple mvebu-reset driver for enabling/disabling PCIe ports
Enabling and disabling PCIe ports is done via address space of system
controller. All 32-bit Armada SoCs use low 4 bits in SoC Control 1 Register
for enabling and disabling some or more PCIe ports. Correct mapping needs
to be set in particular DTS files.

DT API for mvebu-reset is prepared for implementing resets also for other
HW blocks, but currently only PCIe is implemented via index 0.

Currently this driver is not used as PCIe ports are automatically enabled
by SerDes code executed by U-Boot SPL. But this will change in followup
patches.

6f139becf6 arm: mvebu: armada-xp/37x.dtsi: Sync PCIe DT nodes with Linux v4.20
This patch sync's the PCIe DT nodes with the recent Linux v4.20 version.
This change makes it easier to reference specific PCIe nodes in the
board dts files to e.g. enable a PCIe port as this is now necessary with
the new DM PCI driver for these platforms.

606576d54b arm: mvebu: Add basic support for Armada 375 eval board db-88f6720
This patch adds basic support for the Marvell A375 eval board. Tested
are the following interfaces:
- I2C
- SPI
- SPI NOR
- Ethernet (mvpp2), port 0 & 1

Currently the A375 SerDes and DDR3 init code is not intergrated. So
the SPL U-Boot is not fully functional.

Right now, this A375 mainline U-Boot can only be used by chainloading
it via the original Marvell U-Boot. This can be done via this
command:

=> tftpboot 00800000 a375/u-boot-dtb.bin;go 00800000
