74673ca705 arm64: zynqmp: Do not include psu_init to U-Boot by default
The commit ed35de6170 ("Convert CONFIG_ZYNQMP_PSU_INIT_ENABLED to
Kconfig") converted CONFIG_ZYNQMP_PSU_INIT_ENABLED symbol and enabled it by
default which is not correct configuration.
Intention of this config was to have it enabled by default for SPL and
provide an option to users to also do low level initialization directly
from U-Boot.
That's why it is necessary to define second symbol with SPL marking in it
and properly use symbols depends on usage in Makefile.
Also disable ZYNQMP_PSU_INIT_ENABLED from boards which enables it by
default. CONFIG_SPL_ZYNQMP_PSU_INIT_ENABLED is enabled by default when SPL
is enabled.

83d2941fe9 arm64: zynqmp: Fix dependencies around ZYNQMP_PSU_INIT_ENABLED
ZYNQMP_PSU_INIT_ENABLED is called only when BOARD_EARLY_INIT_F is defined
that's why cover this dependency in Kconfig.
 board_early_init_f() is only part related to
CONFIG_ZYNQMP_PSU_INIT_ENABLED which is disabled now that's why disable
BOARD_EARLY_INIT_F and also build board_early_init_f() only when
CONFIG_BOARD_EARLY_INIT_F is enabled.

398a74ae33 zynqmp: restore the jtag interface
When boot.bin is configured for secure boot the CSU will disable the
JTAG interface on all cases.

Some boards might rely on this interface for flashing to QSPI in which
case those systems might end up bricked during development.

This commit will restore the interface under CSU control

01c7714a7b zynqmp: spl: support DRAM ECC initialization
Use the ZDMA channel 0 to initialize the DRAM banks. This avoid
spurious ECC errors that can occur when accessing unitialized memory.

The feature is enabled by setting the option
CONFIG_SPL_ZYNQMP_DRAM_ECC_INIT and providing the following data:

 SPL_ZYNQMP_DRAM_BANK1_BASE: start of memory to initialize
 SPL_ZYNQMP_DRAM_BANK1_LEN : len of memory to initialize (hex)
 SPL_ZYNQMP_DRAM_BANK2_BASE: start of memory to initialize
 SPL_ZYNQMP_DRAM_BANK2_LEN : len of memory to initialize (hex)

Setting SPL_ZYNQMP_DRAM_BANK_LEN to 0 takes no action.

de79ca9512 arm64: zynqmp: Add board_boot_order for MMC boot extension
In past SPL_ZYNQMP_TWO_SDHCI symbol was introduced to handle boards with
two sdhci controllers. The problem was that U-Boot is registering
controllers based on aliases in DT but bootmode targets specific controller
ID. That's why on boards with one "second" sdhci controller bootmode was
pointing to second controller(MMC2) but alias was setup to mmc0 (the first
controller). And SPL requires to point to mmc0 in this case.

Long time ago commit f101e4bd37
("spl: add support for alternative boot device") added support for handling
multiple bootmodes in SPL. Use this functionality and setup second sdhci
controller as backup boot device.

Below is table with behavior:
HW/bootmode  bootorder
sd0/sd0      mmc0/mmc1 (mmc1 never called)
sd1/sd1      mmc1/mmc0 (mmc0 fails and mmc1 is called)
sd0+sd1/sd0  mmc0/mmc1 (mmc1 never called)
sd0+sd1/sd1  mmc1/mmc0 (mmc0 never called)

All other bootmodes are not affected but order can be extended to cover
advance boot flows.

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)
  Loading PMUFW cfg obj (2008 bytes)

Origin symbols were used in full u-boot but with moving to distro boot
