From 6919b4bf36357463b419c4b848b5778d7ba0874e Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Fri, 22 Apr 2016 11:48:49 +0200 Subject: ARM64: zynqmp: Add support for reading MAC from eeprom Add support for on board eeprom with programmed MAC for using in u-boot to have uniq address for every board. Most of the time uniq MAC address is on a label on the board. If address is not programmed use these command to program it.

The same solution was used on Xilinx Zynq. The patch also change CONFIG_SYS_INIT_SP_ADDR to the end of OCM which stays at the same location all the time. Bootrom expects starting address to be at 0xfffc0000 that's why this address is SPL_TEXT_BASE.

Based on selected bootmode boot_targets are rewritten. Patch also contains detection if variables are saved. If yes don't rewrite boot_targets variable. Also move variable setup to the end of file because SCSI needs to be defined before others macros are using it.
