7171d99296 stm32mp: stpmic1: remove the debug unit request by debugger
Depending on backup register value, U-Boot SPL maintains the debug unit
powered-on for debugging purpose; only BUCK1 is required for powering
the debug unit, so revert the setting for all the other power lanes,
except BUCK3 that has to be always on.

To be functional this patch requires a modification in the debugger
,openocd for example, to update the STM32MP15 backup register when it is
required to debug SPL after reset. After deeper analysis this behavior
will be never supported in tools so the associated code, will be never
used and the associated code can be removed.

* x2 Gigabit Ethernet interfaces capable of working in Switch and MAC mode
* x1 HDMI Port with audio + x1 OLDI/LVDS Display interface for Dual Display
* x1 Headphone Jack
* x1 USB2.0 Hub with two Type A host and x1 USB Type-C DRP Port
* x1 UHS-1 capable µSD card slot
* 2.4/5 GHz WLAN + Bluetooth 4.2 through WL1837
* 512 Mbit OSPI flash
* x4 UART through UART-USB bridge
* XDS110 for onboard JTAG debug using USB
* Temperature sensors, user push buttons and LEDs
* 40-pin User Expansion Connector
* 24-pin header for peripherals in MCU island (I2C, UART, SPI, IO)
* 20-pin header for Programmable Realtime Unit (PRU) IO pins
* 15-pin CSI header

Add basic support for AM62-SK.

To keep the changes to minimum. Only UART And SD are supported at the

900349b7dd board: ti: Introduce the basic files to support AM62 SK board
Add basic support for AM62 SK. This has 2GB DDR.
Note that stack for R5 SPL is in OCRAM @ 0x7000ffff so that is away from
BSS and does not step on BSS section

Add only the bare minimum required to support UART and SD.
