Add support for reading out the MAC address from SoC fuses on DH STM32MP1 DHSOM.
The DH STM32MP1 DHSOM may contain external ethernet MACs, which benefit from the
MAC address stored in SoC fuses as well, handle those consistently. This however
means the architecture setup_mac_address() cannot be used and instead a simpler
local fuse read out is implemented in the board file.

This patch series adds basic support for the boards based on Airoha
EN7523/EN7529/EN7562 SoCs. Due to ATF restrictions these boards are
able to run 32-bit OS only.
This patch series adds support for the following hardware:
* console UART
* ethernet controller/switch
* spinand flash (in non-dma mode)
The following issues may be expected:
* Extra slow UBI attaching in U-Boot (up to 20 sec with fastmap enabled).
This is caused by the lack of DMA support in the U-Boot airoha-snfi driver.
* Linux airoha-snfi driver in some cases might damage you flash data
(see: https://lore.kernel.org/lkml/20251012121707.2296160-15-mikhail.kshevetskiy@iopsys.eu/)
* Latest linux kernel is recommended to properly support flashes
with more than one plane per lun
(see: https://lore.kernel.org/lkml/20251012121707.2296160-7-mikhail.kshevetskiy@iopsys.eu/)
* It's NOT recommended to use flashes working in continuous mode because
U-Boot airoha-snfi driver does not support such flashes properly.
The patches was tested on the board:
- SoC: Airoha EN7562
- RAM: 512 MB
- SPI NAND: 4 Gbit, made by Toshiba
- Linux boot: was NOT tested
The U-Boot was chain-loaded from the running U-Boot. Airoha ATF-2.3 does
not allow easily chain-loading of U-Boot from U-Boot, so a special FIT
image (mimic linux kernel) was created
1) Create u-boot.its file with the following contents:
=== cut here ===
/dts-v1/;

#address-cells = <1>;

TI's AM6254atl (or AM62x SiP for short) provides the existing AM62x SoC
with 512MiB of DDR integrated in a single package.
This patch adds the necessary U-Boot devie tree files, the required
defconfigs along with the documentation for the AM62x SiP EVM.
AM62x SiP differs from the already supported AM62x in following ways:
- OP-TEE for the AM62x resides from 0x9e800000 to 0xa0000000 which needs
to be moved to 0x80080000 to free up space at end of DDR in AM62x SiP
with 512MiB of memory. This is required to allow U-Boot to relocate to
end of DDR before booting to the kernel.
- Changes to the env:
1. splashimage address updated from 0x80200000 to 0x81a00000
2. DFU addresses updated to match updated TEXT_BASE for SPL and U-Boot

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.

Anbernic RG353M is hardware compatible with RG353P. Only the form-factor

"Anbernic RG353P" as default model. If a RG353M is detected, the model
should be overwritten with the correct name.
Actually, it's overwritten with "Anbernic" only making the process of
machine detection a little harder.
However, to determine the size of the string "Anbernic RG353M", it is
sizeof() which is used resulting in obtaining the size of the pointer
(which is 8 bytes on ARM64) not the size of the pointed string.
strlen() should be used instead.
