This allows to concatenate spl and u-boot binaries together.
Previously, both binaries has to be flashed separately at the correct
offset (spl at offset 0 and u-boot at offset 0x8000).
With this patch, only one binary is generated (u-boot-with-spl.bin)
and has to be copied in flash at offset 0 using openocd for example
or simply copied in exported mass storage.

Replace CONFIG_SUPPORT_SPL by CONFIG_SPL_BUILD to allow
dram_init() execution when using none SPL defconfig
(stm32f746-disco_defconfig).

As stm32f46-disco, stm32f769-disco and stm32746g-eval are very similar
except their respective device tree file. These 3 boards uses the same
TARGET_STM32F746_DISCO flag (so same include/configs/stm32f746-disco.h
and same board file board/st/stm32f746-disco/stm32f746-disco.c)
To be able to compile these 3 boards, replace the hard-coded device-tree
name in include/configs/stm32f746-disco.h by CONFIG_DEFAULT_DEVICE_TREE
which is set in each board defconfig file with the correct value.

+STM32 MCU boards
+=================
+
+This is a quick instruction for setup STM32 MCU boards.
+

+
+SoCs information:
+-----------------
+STM32F4 series are Cortex-M4 MCU.
+STM32F7 and STM32H7 series are Cortex-M7 MCU.
+
+ + STM32F4 series: https://www.st.com/en/microcontrollers-microprocessors/stm32f4-series.html
+ + STM32F7 series: https://www.st.com/en/microcontrollers-microprocessors/stm32f7-series.html

+
+Currently the following boards are supported:
+
+ + stm32f429-disco.dts
+ + stm32f469-disco.dts
+ + stm32746g-eval.dts
+ + stm32f746-disco.dts
+ + stm32f769-disco.dts
+ + stm32h743i-disco.dts
+ + stm32h743i-eval.dts
+ + stm32h750i-art-pi.dts
+
+Boot Sequences
+--------------
+
+For STM32F7 series, 2 boot configurations are supported with and without SPL
+
++----------+------------------------+-------------------------+--------------+
+| **ROM** | **FSBL** | **SSBL** | **OS** |
++ **code** +------------------------+-------------------------+--------------+
+| | First Stage Bootloader | Second Stage Bootloader | Linux Kernel |
++ +------------------------+-------------------------+--------------+
+| | embedded Flash | DDR |
++----------+------------------------+-------------------------+--------------+
+
+The boot chain with SPL
+```````````````````````
+
+defconfig_file :
+ + **stm32746g-eval_spl_defconfig**
+ + **stm32f746-disco_spl_defconfig**
+ + **stm32f769-disco_spl_defconfig**
+
++-------------+------------+------------+-------+
+| ROM code | FSBL | SSBL | OS |
++ +------------+------------+-------+
+| |U-Boot SPL | U-Boot | Linux |
++-------------+------------+------------+-------+
+
+The boot chain without SPL
+``````````````````````````
+
+defconfig_file :
+ + **stm32f429-discovery_defconfig**
+ + **stm32f429-evaluation_defconfig**
+ + **stm32f469-discovery_defconfig**
+ + **stm32746g-eval_defconfig**
+ + **stm32f746-disco_defconfig**
+ + **stm32f769-disco_defconfig**
+ + **stm32h743-disco_defconfig**
+ + **stm32h743-eval_defconfig**
+ + **stm32h750-art-pi_defconfig**
+
++-------------+-----------+-------+
+| ROM code | FSBL | OS |
++ +-----------+-------+
+| |U-Boot | Linux |
++-------------+-----------+-------+
+
+Build Procedure
+---------------
+
+1. Install the required tools for U-Boot
+
+ * install package needed in U-Boot makefile
+ (libssl-dev, swig, libpython-dev...)
+
+ * install ARMv7 toolchain for 32bit Cortex-A (from Linaro,
+ from SDK for STM32MP15x, or any crosstoolchains from your distribution)
+ (you can use any gcc cross compiler compatible with U-Boot)
+
+2. Set the cross compiler::
+
+ # export CROSS_COMPILE=/path/to/toolchain/arm-linux-gnueabi-
+
+3. Select the output directory (optional)::
+
+ # export KBUILD_OUTPUT=/path/to/output
+
+ for example: use one output directory for each configuration::
+
+ # export KBUILD_OUTPUT=stm32f4
+ # export KBUILD_OUTPUT=stm32f7
+ # export KBUILD_OUTPUT=stm32h7
+
+ you can build outside of code directory::
+
+ # export KBUILD_OUTPUT=../build/stm32f4
+
+4. Configure U-Boot::
+
+ # make <defconfig_file>
+
+ For example with <defconfig_file>:
+
+ - For **stm32f429 discovery** board : **stm32f429-discovery_defconfig**
+ - For **stm32f769 discovery** board with SPL: **stm32f769-disco_spl_defconfig**
+ - For **stm32f769 discovery** board without SPL: **stm32f769-disco_defconfig**
+
+5. Configure the device-tree and build the U-Boot image::
+
+ # make DEVICE_TREE=<name> all
+
+ Examples:
+
+ a) boot with SPL on stm32f746 discovery board::
+
+ # export KBUILD_OUTPUT=stm32f746-disco
+ # make stm32f746-disco_spl_defconfig
+ # make DEVICE_TREE=stm32f746-disco all
+
+ b) boot without SPL on stm32f746 discovery board::
+
+ # export KBUILD_OUTPUT=stm32f746-disco
+ # make stm32f746-disco_defconfig
+ # make DEVICE_TREE=stm32f746-disco all
+
+ c) boot on stm32h743 discovery board::
+
+ # export KBUILD_OUTPUT=stm32h743-disco
+ # make stm32h743-disco_defconfig
+ # make DEVICE_TREE=stm32h743i-disco all
+
+ d) boot on stm32h743 evaluation board::
+
+ # export KBUILD_OUTPUT=stm32h743-disco
+ # make stm32h743-eval_defconfig
+ # make DEVICE_TREE=stm32h743i-eval all
+
+6. U-Boot Output files
+
+ So in the output directory (selected by KBUILD_OUTPUT),
+ you can found the needed U-Boot files, for example::
+
+ - stm32f746-disco_defconfig = **u-boot-dtb.bin** and **u-boot.dtb**
+
+ - FSBL = u-boot-dtb.bin
+
+ - stm32f746-disco_spl_defconfig = **u-boot-dtb.bin**, **u-boot.dtb** and **u-boot-with-spl.bin**
+
+ - FSBL + SSBL = u-boot-with-spl.bin
+ - SSBL = u-boot-dtb.bin
+
+7. Flash U-Boot files
+
+Plug STM32 MCUs board using the USB ST-Link connector, hence it will expose
+the flash area as a mass-storage. In this mass-storage you will find the
+following files:
+
+- DETAILS.TXT: give the bootrom version and build
+- MBED.HTM: shortcul to the hardware board description web page from st.com.
+
+Copy/paste the u-boot.bin to this mass-storage. The "COM" LED will
+blink alternatively red and green during the flash process.
+When done the board will reboot automatically.
+
+In case of boot with SPL, by default SPL will try to load either a Linux
+kernel (falcon mode) or, if the key "c" is maintained pressed, the main U-Boot.

>> +Build Procedure
>> +---------------
>> +
>> +1. Install the required tools for U-Boot
>> +
>> + * install package needed in U-Boot makefile
>> + (libssl-dev, swig, libpython-dev...)
>> +
>> + * install ARMv7 toolchain for 32bit Cortex-A (from Linaro,
>> + from SDK for STM32MP15x, or any crosstoolchains from your
>> distribution)
>> + (you can use any gcc cross compiler compatible with U-Boot)
>> +
>> +2. Set the cross compiler::
>> +
>> + # export CROSS_COMPILE=/path/to/toolchain/arm-linux-gnueabi-
>> +
>> +3. Select the output directory (optional)::
>> +
>> + # export KBUILD_OUTPUT=/path/to/output
>> +
>> + for example: use one output directory for each configuration::
>> +
>> + # export KBUILD_OUTPUT=stm32f4
>> + # export KBUILD_OUTPUT=stm32f7
>> + # export KBUILD_OUTPUT=stm32h7
>> +
>> + you can build outside of code directory::
>> +
>> + # export KBUILD_OUTPUT=../build/stm32f4
>> +
>> +4. Configure U-Boot::
>> +
>> + # make <defconfig_file>
>> +
>> + For example with <defconfig_file>:
>> +
>> + - For **stm32f429 discovery** board :
>> **stm32f429-discovery_defconfig**
>> + - For **stm32f769 discovery** board with SPL:
>> **stm32f769-disco_spl_defconfig**
>> + - For **stm32f769 discovery** board without SPL:
>> **stm32f769-disco_defconfig**
>> +
>> +5. Configure the device-tree and build the U-Boot image::
>> +
>> + # make DEVICE_TREE=<name> all
> it is not required as the supported device tree is selected in each
> defconfig.
>
> # make all
>
>> +
>> + Examples:
>> +
>> + a) boot with SPL on stm32f746 discovery board::
>> +
>> + # export KBUILD_OUTPUT=stm32f746-disco
>> + # make stm32f746-disco_spl_defconfig
>> + # make DEVICE_TREE=stm32f746-disco all
> # make all
>> +
>> + b) boot without SPL on stm32f746 discovery board::
>> +
>> + # export KBUILD_OUTPUT=stm32f746-disco
>> + # make stm32f746-disco_defconfig
>> + # make DEVICE_TREE=stm32f746-disco all
>
>
> # make all
>
>> +
>> + c) boot on stm32h743 discovery board::
>> +
>> + # export KBUILD_OUTPUT=stm32h743-disco
>> + # make stm32h743-disco_defconfig
>> + # make DEVICE_TREE=stm32h743i-disco all
>
> # make all
>
>> +
>> + d) boot on stm32h743 evaluation board::
>> +
>> + # export KBUILD_OUTPUT=stm32h743-disco
>> + # make stm32h743-eval_defconfig
>> + # make DEVICE_TREE=stm32h743i-eval all
>
> # make all
>
>> +
>> +6. U-Boot Output files
>> +
>> + So in the output directory (selected by KBUILD_OUTPUT),
>> + you can found the needed U-Boot files, for example::
>> +
>> + - stm32f746-disco_defconfig = **u-boot-dtb.bin** and
>> **u-boot.dtb**
>> +
>> + - FSBL = u-boot-dtb.bin
>> +
>> + - stm32f746-disco_spl_defconfig = **u-boot-dtb.bin**,
>> **u-boot.dtb** and **u-boot-with-spl.bin**
>> +
>> + - FSBL + SSBL = u-boot-with-spl.bin
>> + - SSBL = u-boot-dtb.bin
>> +
>> +7. Flash U-Boot files
>> +
>> +Plug STM32 MCUs board using the USB ST-Link connector, hence it will
>> expose
>> +the flash area as a mass-storage. In this mass-storage you will find
>> the
>> +following files:
>> +
>> +- DETAILS.TXT: give the bootrom version and build
>> +- MBED.HTM: shortcul to the hardware board description web page from
>> st.com.
>> +
>> +Copy/paste the u-boot.bin to this mass-storage. The "COM" LED will
>> +blink alternatively red and green during the flash process.
>> +When done the board will reboot automatically.
>> +
>> +In case of boot with SPL, by default SPL will try to load either a
>> Linux
>> +kernel (falcon mode) or, if the key "c" is maintained pressed, the
>> main U-Boot.
