From: Frieder Schrempf <frieder.schrempf at kontron.de>

SoMs and boards that are manufactured at Kontron Electronics
Germany (KED) get UIDs programmed to the OTP fuses. This adds support
for extracting them from the fuses and exporting them to the serial
console and Linux.

Frieder Schrempf (4):
  imx: kontron-sl-mx6ul: Enable CONFIG_BOARD_LATE_INIT to fix auto
    fastboot
  imx: kontron: Add common function to get HW UIDs from OTPs
  imx: kontron-sl-mx6ul: Add support for reading HW UIDs
  imx: kontron-sl-mx8mm: Add support for reading HW UIDs
