On linux kernel side, on STM32F7 and STM32H7 SoCs, DMA requires
uncachable regions. These regions are defined in DT.
Since kernel linux v4.15, on ARMv7-M Cortex, kernel is able
to configure MPU regions depending on DT settings.
As kernel is able to configure MPU, this allows to remove
MPU region settings in bootloader.
On Cortex M processors, MPU allows to use a default memory map.
(see B3.5.4 MPU Control Register, MPU_CTRL in
https://developer.arm.com/products/architecture/m-profile/docs/ddi0403/latest/armv7-m-architecture-reference-manual)
Use the default memory map as background region for all STM32 SoCs
family with an additional MPU region corresponding to the SDRAM area.

Booting a aarch64 Linux kernel requires the image to be placed
text_offset bytes from a 2MB aligned address.
See https://www.kernel.org/doc/Documentation/arm64/booting.txt
booti_setup() takes care about this alignment and will relocate the
image if not properly aligned with memmove(). This can require up
to double the size of the loaded image and therefore accidentally
overwrite content placed there (i.e ramdisk_addr_r) for large kernel
images.
By adding text_offset to the default kernel_addr_r we can prevent that
from happening for kernels larger 18MB and also save a few cycles.
We can assume a text_offset of 0x80000 for most cases, all others will be
handled by booti_setup() anyway.

* Second LAN8710A Megabit PHY
* 16MB SPI Flash memory
* eMMC card
* ATECC508 crypto device
The EVB board has:
* Debug UART
* MicroSD card connector

CONFIG_PHY_ADDR is used for old-style configuration. This makes
impossible changing the PHY address, if multiple boards share a same
config header file (for example include/configs/sunxi-common.h).
Moving this to Kconfig helps overcoming this issue. It's defined
as entry inside PHYLIB section.
After the implemention, moveconfig was run. The issues are:
- edb9315a - CONFIG_PHYLIB is not enabled. Entry is
deleted.
- ds414 - CONFIG_PHYLIB is in incompatible format:
{ 0x1, 0x0 }. This entry is also deleted.
- devkit3250 - The PHY_ADDR is in hex format (0x1F).
Manually CONFIG_PHY_ADDR=31 is added in
the defconfig.
After the changes the suspicious defconfigs passes building.
