* x2 Gigabit Ethernet interfaces capable of working in switch and MAC mode
* x1 USB 3.0 Type-A port
* x1 UHS-1 capable µSD card slot
* 2.4/5 GHz WLAN + Bluetooth 4.2 through WL1837
* 512 Mbit OSPI flash
* x2 UART through UART-USB bridge
* XDS110 for onboard JTAG debug using USB
* Temperature sensors, user push buttons and LEDs
* 40-pin Raspberry Pi compatible GPIO header
* 24-pin header for peripherals in MCU island (I2C, UART, SPI, IO)
* 54-pin header for Programmable Realtime Unit (PRU) IO pins
* Interface for remote automation. Includes:
* power measurement and reset control
* boot mode change
Add basic support for AM642 SK.

Now that single defconfig can be used for booting AM64 EVM and SK,
default device tree will not work for selecting dtb for kernel.

Current BSS allocation of SPL is as below:
size spl/u-boot-spl
text data bss dec hex filename
144572 5484 1752 151808 25100 spl/u-boot-spl
But 20KB is allocated currently for BSS. Reduce it to 4KB and
save some space for stack.

Introduce support for the AM64 DDRSS controller which uses the 16bit
variation of the controller. This controller shares much functionality
with the existing J721e support, so this patch introduces only the new
code needed for am64 specific support from "_16bit_" files with headers
under "16bit/" include path/.
Also add a CONFIG_K3_AM64_DDRSS option to the choice required for use
with CONFIG_K3_DDRSS to allow selecting AM64 support.

Introduce a new version of the ddr driver which has the ability to

Create a new CONFIG_K3_DDRSS option to select the common parts of the

corresponding Kconfig as required.

The AM642 SoC belongs to the K3 Multicore SoC architecture platform,
providing advanced system integration to enable applications such as
Motor Drives, PLC, Remote IO and IoT Gateways.
Some highlights of this SoC are:
* Dual Cortex-A53s in a single cluster, two clusters of dual Cortex-R5F
MCUs, and a single Cortex-M4F.
* Two Gigabit Industrial Communication Subsystems (ICSSG).
* Integrated Ethernet switch supporting up to a total of two external
ports.
* PCIe-GEN2x1L, USB3/USB2, 2xCAN-FD, eMMC and SD, UFS, OSPI memory
controller, QSPI, I2C, eCAP/eQEP, ePWM, ADC, among other
peripherals.
* Centralized System Controller for Security, Power, and Resource
Management (DMSC).

AM64x uses a different thread mapping that existing K3 SoCs, so update
the valid thread ID list to include those used for AM64x.
Also remove the comment identifying the purpose of each thread ID. The
purpose of the thread ID is specified when describing the threads in the
device tree and the same ID can mean different things on different SoCs,
so the comment is not useful.

Change the memory attributes for the DDR regions used by the remote
