"Private data is created when the device is probed and freed when the
device is removed.
Platform data is created when the device is bound, and survives

Strictly speaking, platform data should be used to hold the decoded

arm/arm64: zynq/zynqmp: pass the PS init file as a kconfig variable
U-Boot needs to link ps7_init_gpl.c on Zynq or psu_init_gpl.c on
ZynqMP (PS init for short). The current logic to locate this file for
both platforms is:
1. if a board-specific file exists in
board/xilinx/zynq[mp]/$(CONFIG_DEFAULT_DEVICE_TREE)/ps?_init_gpl.c
then use it
2. otherwise use board/xilinx/zynq/ps?_init_gpl.c
In the latter case the file does not exist in the U-Boot sources and
must be copied in the source tree from the outside before starting the
build. This is typical when it is generated from Xilinx tools while
developing a custom hardware. However making sure that a
board-specific file is _not_ found (and used) requires some trickery
such as removing or overwriting all PS init files (e.g.: the current
meta-xilinx yocto layer).
This generates a few problems:
* if the source tree is shared among different out-of-tree builds,
they will pollute (and potentially corrupt) each other
* the source tree cannot be read-only
* any buildsystem must add a command to copy the PS init file binary
* overwriting or deleting files in the source tree is ugly as hell
Simplify usage by allowing to pass the path to the desired PS init
file in kconfig variable XILINX_PS_INIT_FILE. It can be an absolute
path or relative to $(srctree). If the variable is set, the
user-specified file will always be used without being copied
around. If the the variable is left empty, for backward compatibility
fall back to the old behaviour.
Since the issue is the same for Zynq and ZynqMP, add one kconfig
variable in a common place and use it for both.
Also use the new kconfig help text to document all the ways to give
U-Boot the PS init file.
Build-tested with all combinations of:
- platform: zynq or zynqmp
- PS init file: from XILINX_PS_INIT_FILE (absolute, relative path,
non-existing), in-tree board-specific, in board/xilinx/zynq[mp]/
- building in-tree, in subdir, in other directory

sunxi: Enable eMMC on Libre Computer Board ALL-H3-CC boards
The Libretech ALL-H3-CC has a high density connector for attaching
an eMMC module. The module form factor and connection is specific
to Libretech, and has provisions for split vmmc/vqmmc (core and I/O)
voltage supplies, but this board does not wire the vqmmc side. The
H2+/H3/H5 SoCs do not support alternate I/O voltages for eMMC either.
Only 3.3V is supported. A specific module that ties vqmmc to vmmc,
with both at 3.3V, must be used.
Given that a) eMMC is not designed to be hotplugged, b) power is
always provided on the pins, and c) MMC controllers can deal with
missing cards, we can enable this by default. If a module is attached
it will be picked up by the system.

has already been queued up for 4.19.

Commit 5dfd5607af2114047bd ("ARM: socfpga: Pull DRAM size from DT") get
memory size from DT. So, we need to update memory size in memory node.
Otherwise, it cause U-boot hang.

lpi2c: Add bus busy error handling
When doing "i2c dev 4; i2c probe" with ENET daughter card connected
on iMX8QXP MEK board, we met a i2c bus busy issue, that the BBF of
lpi2c always show busy, but the master is idle, and stop is detected
(SDF set).
This patch addes a handling to re-init the lpi2c master for this
case. Then the issue can be worked around.

lpi2c: Fix bus stop problem in xfer
In xfer function, both bus_i2c_read and bus_i2c_write will
send a STOP command. This causes a problem when reading register
data from i2c device.
Generally two operations comprise the register data reading:
1. Write the register address to i2c device.
START | chip_addr | W | ACK | register_addr | ACK |
2. Read the Data from i2c device.
START | chip_addr | R | ACK | DATA | NACK | STOP
The STOP command should happen at the end of the transfer, otherwise
we will always get data from register address 0

imx: lpi2c: fix clock issue when NACK detected
For LPI2C IP, NACK is detected by the rising edge of the ninth clock.
In current uboot driver, once NACK is detected, it will reset and then
disable LPI2C master. As a result, we can never see the falling edge
of the ninth clock.

ARM: socfpga: Assure correct ACTLR configuration
Make sure the ARM ACTLR register has correct configuration, otherwise
the Linux kernel refuses to boot. In particular, the "Write Full Line
of Zeroes" bit must be cleared.
