b529993e02 spl: add hierarchical defaults for SPL_LDSCRIPT
With SPL_LDSCRIPT moved to Kconfig (and this being a 'string' config
node), all the lingering definitions in header files will cause
warnings/errors due to the redefinition of the configuration item.

As we don't want to pollute the defconfig files (and values should
usually be identical for entire architectures), the defaults are moved
into Kconfig.  Kconfig will always pick the first default that
matches, so please keep these values at the end of each file (to allow
any board-specific Kconfig, which will be included earlier) to
override with an unconditional default setting.

f5e46b4919 zynq: Add EFI runtime sections to linker script
When using EFI_LOADER, we add a few special sections for runtime code and
data which get relocated on demand when executing a target OS.

These runtime structures need to get annotated properly in the linker script.
While we do that properly in the generic one, we missed out on the zynq
specific linker script.

This patch adds the EFI runtime section annotations into the zynq linker script
so that the efi loader code actually works on that platform.

3b6460809c tools: mkimage: Add support for initialization table for Zynq and ZynqMP
The Zynq/ZynqMP boot.bin file contains a region for register initialization
data. Filling in proper values in this table can reduce boot time
(e.g. about 50ms faster on QSPI boot) and also reduce the size of
the SPL binary.

The table is a simple text file with register+data on each line. Other
lines are simply skipped. The file can be passed to mkimage using the
"-R" parameter.

It is recommended to add reg init file to board folder.
For example:
CONFIG_BOOT_INIT_FILE="board/xilinx/zynqmp/xilinx_zynqmp_zcu102/reg.int

2b1cdafa9f common: Pass the boot device into spl_boot_mode()
The SPL code already knows which boot device it calls the spl_boot_mode()
on, so pass that information into the function. This allows the code of
spl_boot_mode() avoid invoking spl_boot_device() again, but it also lets
board_boot_order() correctly alter the behavior of the boot process.

The later one is important, since in certain cases, it is desired that
spl_boot_device() return value be overriden using board_boot_order().

135aa95002 clk: convert API to match reset/mailbox style
The following changes are made to the clock API:
* The concept of "clocks" and "peripheral clocks" are unified; each clock
  provider now implements a single set of clocks. This provides a simpler
  conceptual interface to clients, and better aligns with device tree
  clock bindings.
* Clocks are now identified with a single "struct clk", rather than
  requiring clients to store the clock provider device and clock identity
  values separately. For simple clock consumers, this isolates clients
  from internal details of the clock API.
* clk.h is split so it only contains the client/consumer API, whereas
  clk-uclass.h contains the provider API. This aligns with the recently
  added reset and mailbox APIs.
* clk_ops .of_xlate(), .request(), and .free() are added so providers
  can customize these operations if needed. This also aligns with the
  recently added reset and mailbox APIs.
* clk_disable() is added.
* All users of the current clock APIs are updated.
* Sandbox clock tests are updated to exercise clock lookup via DT, and
  clock enable/disable.
* rkclk_get_clk() is removed and replaced with standard APIs.

Buildman shows no clock-related errors for any board for which buildman
can download a toolchain.

test/py passes for sandbox (which invokes the dm clk test amongst
others).

Due to licensing issues, the files ps7_init.c/h are not able to be
distributed with U-Boot source code.  Recent Xilinx tools also
provide the GPL variants (ps7_init_gpl.c/h), compatible with U-Boot
license.

Prior to this commit, we had to copy ps7_init files into
board/xilinx/zynq/ before the compile.

To be more user-friendly, let's include ps7_init_gpl.c/h for
Zedboard, MicroZed, ZC702, ZC706.

These init code have been taken from the hwplatform_templates
directory of Xilinx SDK 2014.4.

You can still use customized ps7_init_gpl.c/h by enabling
CONFIG_ZYNQ_CUSTOM_INIT.  The recommended directory for storing them
is now board/xilinx/zynq/custom_hw_platform, but board/xilinx/zynq
is still supported for backward compatibility.  The latter emits
a warning message to prompt users to gradually switch to the new
directory.

This commit introduces separate configuration for them, which makes
the next commit much easier.

Going forward, the recommended build commands are:

ZC702: make zynq_zc702_defconfig && make
ZC706: make zynq_zc706_defconfig && make

Although the old work flow is still supported, CONFIG_TARGET_ZC70X
has been marked as deprecated.  If used, the warning message is
shown to prompt users to switch to the new scheme.
