b9ad74d901 Revert "ARM: davinci: da850: Manual pinmux only when PINCTRL not available"
This reverts commit 877ab2423b.

The above patch was designed to shrink code by only pin-muxing items
needed for SPL in SPL and relying on driver model or SPL to mux other
items.  Unfortunately, da850evm_direct_nor doesn't use SPL so items
that were only muxed during SPL are not muxed causing the board
to no longer boot.

c28a9cfa40 arm64: zynqmp: spl: install a PMU firmware config object at runtime
Optionally allow U-Boot to load a configuration object into the Power
Management Unit (PMU) firmware on Xilinx ZynqMP.

The configuration object is required by the PMU FW to enable most SoC
peripherals. So far the only way to boot using U-Boot SPL was to hard-code
the configuration object in the PMU firmware. Allow a different boot
process, where the PMU FW is equal for any ZynqMP chip and its
configuration is passed at runtime by U-Boot SPL.

All the code for Inter-processor communication with the PMU is isolated in
a new file (pmu_ipc.c). The code is inspired by the same feature as
implemented in the Xilinx First Stage Bootloader (FSBL) and Arm Trusted
Firmware:

 * fb647e6b4c/lib/sw_apps/zynqmp_fsbl/src/xfsbl_misc_drivers.c (L295)
 * c48d02bade/plat/xilinx/zynqmp/pm_service/pm_api_sys.c (L357)

SPL logs on the console before loading the configuration object:

  U-Boot SPL 2019.07-rc1-00511-gaec224515c87 (May 15 2019 - 08:43:41 +0200)

bb4c5d6055 board: mediatek: Add pumpkin board support
The pumpkin board is made by Gossamer Engineering and is using
a MediaTek SoC. The board currently comes in two available version:
MT8516 SoC and MT8167 SoC.
The board provides the following IOs: eMMC, NAND, SD card, USB type-A,
Ethernet, Wi-Fi, Bluetooth, Audio (jack out, 2 PDM port, 1 analog in),
serial over USB, and an expansion header.

Additionally there is a HDMI port, DSI port, and camera port only
on the MT8167 version of the board.

The board can be powered by battery and/or via a USB Type-C port and
is using a PMIC MT6392.

The eMMC and NAND are sharing pins and cannot be used together.

This commit is adding the basic boot support for the Pumpkin MT8516
board on the eMMC.

67a4df9daf ARM: am3517-evm: Remove non-DM legacy code
With both SPL and U-Boot now supporting DM, we can start removing
legacy code.  This patch removes the legacy MMC initalization and
legacy I2C initialization since both are now available via DM and
device tree.

e054be5bab ARM: da850-evm: Remove repeated pinmuxing calls
arch_cpu_init() initializes the pinmuxing which is called fairly
early in the start sequences, so the board_init function doesn't
need to do it again.  This patch removes the call from board_init.

938359c570 ARM: da850-evm: Remove duplicate UART initialization
The Low Level init functions start the UART, so it doesn't need
to happen during board_init.  This patch removes it from
board_init.

9de4695f75 ARM: am3517-evm: Remove manual ethernet reset code
The reset line going to the ethernet controller is controlled
by a global reset controlling multiple peripherals.  There
is no need to manually invoke the reset.

e809285d49 net: davinci_emac: convert to using the driver model
Now that we removed all legacy boards selecting TI_EMAC we can
completely convert the driver code to using the driver model.
This patch also updates all remaining users of davinci_emac.

8782122052 Add support for the NXP LS1021A-TSN board
The LS1021A-TSN is a development board built by VVDN/Argonboards in
partnership with NXP.

It features the LS1021A SoC and the first-generation SJA1105T Ethernet
switch for prototyping implementations of a subset of IEEE 802.1 TSN
standards.

Supported boot media: microSD card (via SPL), QSPI flash.

Rev. A of the board uses a Spansion S25FL512S_256K serial flash, which
is 64 MB in size and has an erase sector size of 256KB (therefore,
flashing the RCW would erase part of U-Boot).

Rev. B and C of the board use a Spansion S25FL256S1 serial flash, which
is only 32 MB in size but has an erase sector size of 64KB (therefore
the RCW image can be flashed without erasing U-Boot).

To avoid the problems above, the U-Boot base address has been selected
at 0x100000 (the start of the 5th 256KB erase sector), which works for
all board revisions. Actually 0x40000 would have been enough, but
0x100000 is common for all Layerscape devices.

eTSEC3 is connecting directly to SJA1105 via an RGMII fixed-link, but
SJA1105 is currently not supported by uboot. Therefore, eTSEC3 is
disabled.

[Vladimir] Code taken from https://github.com/openil/u-boot (which
itself is mostly copied from ls1021a-iot) and adapted with the following
changes:

- Add a008850 errata workaround
- Converted eTSEC, MMC to DM to avoid all build warnings
- Plugged in distro boot feature, including support for extlinux.conf
- Added defconfig for QSPI boot
- Added the board/freescale/ls1021atsn/README.rst for initial setup
- Increased CONFIG_SYS_MONITOR_LEN so that the SPL malloc pool does not
  get overwritten during copying of the u-boot.bin payload from MMC to
  DDR.
