0d38a5fd44 mx25: fix the offset between the USB ports' registers
The USBOH module on imx25 chips contains two USB controllers which are
called USB OTG Controller and USB Host Controller. Each one has its EHCI
root hub. The OTG Controller's EHCI registers start at offset 0, the Host
Controller's registers start at offset 0x400.

We set CONFIG_MXC_USB_PORT=0 to select the OTG Controller and 1 for the
Host Controller. Therefore, IMX_USB_PORT_OFFSET must be 0x400. Using
this setting, the Host Controller starts working on my imx25 board.

Please note that the imx25 reference manual claims that the Host
Controller's registers start at 0x200. This is not correct. The Linux
Kernel uses the correct offset 0x400 in imx25.dtsi.

bbbb50f9fd imx: i.mx6q: imx6q_logic: Migrate to SPL and enable SDP
Since the vast majority of i.MX6 boards are migrating to SPL,
this patch converts im6q_logic to SPL and enables the SDP for
loading SPL and u-boot.img over USB.  The Falcon mode only
supports NAND flash as of now due to limited space/RAM, but
all i.MX6D/Q SOM's from Logic PD have internal NAND from which
to boot.

d5b7177f91 pico-imx7d: Add SPL support
Convert pico-imx7d to SPL support.

There are two variants of pico-imx7d SOMs:
- One with 512MB of RAM
- One with 1GB of RAM

The 512MB module contains two Hynix H5TC2G63GFR-PBA.
The 1GB module contains two Hynix H5TC4G63GFR-PBA.

The RAM size is determined in runtime by reading GPIO1_12.

While at it, also add USB Serial Download mode support as it
is very helpful for loading SPL and u-boot.img via imx_usb_loader.

9ea7519383 arm, imx6: add alternative PAD_CTL_DSE constants
Not all i.MX6 pads use the same drive strength table. So far only the
240 Ohm to 34 Ohm table was available. Because the constants used have
speaking names it can be confusing to use e.g. PAD_CTL_DSE_48ohm when
according to the reference manual 52 Ohm is the correct value. This
patch adds the 260 Ohm to 37 Ohm table.

For example, the IOMUXC_SW_PAD_CTL_PAD_SD2_CLK register (SD-card clock)
uses the added table.

a89eb89b38 imx: mx7: psci: provide complete PSCI 1.0 implementation
PSCI 1.0 require PSCI_VERSION, PSCI_FEATURES, AFFINITY_INFO and
CPU_SUSPEND to be implemented. Commit 0ec3d98f76 ("mx7_common:

be PSCI 1.0 compliant but failed to implement those functions.
Especially the missing PSCI version callback was noticeable when
booting Linux:

315ded9730 rockchip: veyron: Set vcc33_sd regulator value
On the veyron board the vcc33_sd regulator is used as vmmc-supply for
the SD card. This regulator is powered in the MMC core during power on
but its value is never actually set.

In the veyron platform the reset value for the LDO output is 1.8V while
the standard (min and max) value for this regulator defined in the DTS
is 3.3V. When the MMC core enable the regulator without setting its
value, the output is automatically set to 1.8V instead of 3.3V.

With this patch we preemptively set the value to 3.3V.

c5d548a9f8 env: common: accept flags on reset to default env
The function set_default_env() sets the hashtable flags for import_r().
Formally set_default_env() doesn't accept flags from its callers. In
practice the caller can (un)set the H_INTERACTIVE flag, but it has to be
done using the first character of the function's string argument. Other
flags like H_FORCE can't be set by the caller.

Change the function to accept flags argument. The benefits are:
1. The caller will have to explicitly set the H_INTERACTIVE flag,
   instead of un-setting it using a special char in a string.
2. Add the ability to propagate flags from the caller to himport(),
   especially the H_FORCE flag from do_env_default() in nvedit.c that
   currently gets ignored for "env default -a -f" commands.
3. Flags and messages will not be coupled together. A caller will be
   able to set flags without passing a string and vice versa.

Please note:
The propagation of H_FORCE from do_env_default() does not introduce any
functional changes, because currently himport_r() is set to destroy the
old environment regardless if H_FORCE flag is set or not. More changes
are needed to utilize the propagation of H_FORCE.

12308b128f lib: fdtdec: Rename routine fdtdec_setup_memory_size()
This patch renames the routine fdtdec_setup_memory_size()
to fdtdec_setup_mem_size_base() as it now fills the
mem base as well along with size.

c7e7948924 arm64: xilinx: Setup default number of chipselects for zcu100
There is only one chipselect on each connector.
Define it directly in board dts file.
There should be an option to use more chipselects via gpios.

37e3a36a54 xilinx: zynq: Add support to secure images
This patch basically adds two new commands for loadig secure
images.
1. zynq rsa adds support to load secure image which can be both
   authenticated or encrypted or both authenticated and encrypted
   image in xilinx bootimage(BOOT.bin) format.
2. zynq aes command adds support to decrypt and load encrypted
   image back to DDR as per destination address. The image has
   to be encrypted using xilinx bootgen tool and to get only the
   encrypted image from tool use -split option while invoking
   bootgen.

6da4f67ad0 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
