54ff4eeb59 board: ti: Kconfig: Correct invalid Kconfig syntax
Kconfig does not support using 'select' to select a 'choice'. A choice
can be configured by either setting the choice symbol to 'y' in a
configuration file or by setting a 'default' of the choice.

In board/ti/*/Kconfig the SOC_K3_* choice is already set to 'y' in their
corresponding configs/*_defconfig file. So remove selecting it.

6a74e2537f include: configs: am62x_evm: Add .env file for Am62x
Use .env file for setting board related environment variables,
in place of am62x_evm.h file. Except for BOOTENV settings, as
config_distro_boot.env file doesn't exist.

d5f563ccdd board: ti: am62x: evm: Add splash screen support
Splash screen function needs splash source information
to load image and display it, splash_location provides
the necessary info, Set default_splash_location to MMC
at partition 1:1. Probe DSS for splash screen display.

4c092bb306 board: ti: am62x: Account for DDR size fixups if ECC is enabled
Call into k3-ddrss driver to fixup device tree and resize
the available amount of DDR if ECC is enabled.

A second fixup is required from A53 SPL to take the fixup
as done from R5 SPL and apply it to DT passed to A53 U-boot,
which in turn passes this to the OS.

249e9f3d19 board: ti: am62x: Use fdt functions for ram and bank init
Use the appropriate fdtdec_setup_mem_size_base() call in
dram_init() and fdtdec_setup_bank_size() in dram_bank_init()
to pull these values from DT, where they are already available,
instead of hardcoding them.

2d257d9279 configs: Add configs for AM62x SK
Add am62x_evm_r5_defconfig for R5 SPL and am62x_evm_a53_defconfig for
A53 SPL and U-Boot support.

To keep the changes to minimum. Only UART And SD boot related configs
are included. This should serve as good starting point for new board
bringup with AM62x.

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.
