Typically we do not enable these configs by default but would still like to
have the option to start building them in our default build flow for
testing. Also there is the added advantage of users being able to see what
is needed in case they choose to enable these features.

Add config fragment support for enabling inline ECC and/or BIST on TI K3
supported platforms.

Signed-off-by: Neha Malcom Francis <n-francis@ti.com>

Enable firmware TPM (fTPM) support via OP-TEE for K3 platforms with
MMC hardware. This provides TPM 2.0 functionality through
Microsoft's fTPM Trusted Application running in OP-TEE secure world,
using eMMC RPMB as persistent storage.

fTPM support in U-Boot provides the foundation for measured boot
and disk encryption use cases.

The ARM64 condition ensures these apply only to A53/A72 cores and the
MMC condition ensures fTPM is enabled only on platforms with eMMC
hardware support.

Prepare v2026.01-rc4

Otherwise the custom-cape eeprom (at address 57) reports NACK which
results into "i2c_write: error waiting for data ACK (status=0x116)" and
terminates further scanning.

This patch fixes a boot failure on the AM64x EVM that was introduced when the do_board_detect function was removed during a refactoring.

It restores the do_board_detect function for the AM64x, AM62x, and AM65x boards to ensure the common board detection logic is executed correctly.

This series adds EEPROM board detection support for AM62x and refactors
the board detection code across AM6x family boards to eliminate code
duplication.

The series introduces two new generic functions for AM6x boards:
- do_board_detect_am6(): Reads the on-board EEPROM with fallback logic
  to alternate I2C addresses
- setup_serial_am6(): Sets up the serial number environment variable
  from EEPROM data

Link: https://lore.kernel.org/r/20251103-am62xeeprom-v3-0-e390779c0fc5@baylibre.com

Add two new generic functions for AM6x family boards to simplify
board-specific implementations:

- do_board_detect_am6(): Generic board detection function that reads
  the on-board EEPROM. It first attempts to read at the configured
  address, and if that fails, tries the alternate address
  (CONFIG_EEPROM_CHIP_ADDRESS + 1). This provides a common
  implementation that can be used across different AM6x boards.

- setup_serial_am6(): Sets up the serial number environment variable
  from the EEPROM data. The serial number is converted from
  hexadecimal string format to a 16-character hexadecimal
  representation and stored in the "serial#" environment variable.

Both functions are protected by CONFIG_IS_ENABLED(TI_I2C_BOARD_DETECT)
and are designed to be used by AM62x, AM64x, AM65x, and other AM6x
family boards.

Add CMD_SPL to list of configs implied by TI_COMMON_CMD_OPTIONS. This
allows the use of 'spl export'[1] command for preparing a device-tree
