menuconfig TDX_CFG_BLOCK
bool "Enable Toradex config block support"
select OF_BOARD_SETUP
select SYSINFO
help
The Toradex config block stored production data on the on-module
flash device (NAND, NOR or eMMC). The area is normally preserved by
software and contains the serial number (out of which the MAC
address is generated) and the exact module type.

Specify the byte offset of the Toradex config block within the flash
device the config block is stored on.

Specify the byte offset of the 2nd instance of the Toradex config block
within the flash device the config block is stored on.
Set to 0 on modules which have no 2nd instance.

help
For each serial number two Ethernet addresses are available for dual
Ethernet carrier boards. This options enables the code to set the
second Ethernet address as environment variable (eth1addr).

adapter EEPROMs.

help
Use the Toradex product ID learned from the config block as USB
product ID. An offset of 0x4000 is added to the product ID since
inside the Toradex vendor ID (0x1b67) the range starting from
offset 0x4000 is reserved for Colibri/Apalis modules.
