1) Load u-boot-tpl.bin to 0xe6300000
2) Write magic number 0x1337c0de to 0xe6300020
TPL checks for this particular magic and starts JTAG recovery
if this number is present. This is not present by default.
3) Start U-Boot TPL from 0xe6300000
4) Wait for a message from TPL on UART indicating JTAG boot:
"JTAG boot detected!"

6) Load U-Boot image (u-boot.img) to 0x4fffffc0

The at24 driver allows to register I2C EEPROM chips using different vendor

when matching using the I2C table since it only has device entries.
But when matching using an OF table, both the vendor and device has to be
taken into account so the driver defines only a set of compatible strings
using the "atmel" vendor as a generic fallback for compatible I2C devices.
So add this generic fallback to the device node compatible string to make
