The "remap" bits in the evaluation board -are configured in order to boot from the internal ROM memory (in -secure mode). - -The boot process as defined by the manufacturer executes external code -(loaded from NAND or OneNAND) that that disables such "security" in -order to run u-boot and later the kernel without constraints. Such -code is a proprietary initial boot loader, called "X-Loader" (in case -anyone wonders, it has no relations with other loaders with the same -name and there is no GPL code inside the ST X-Loader). - -SDRAM configuration, PLL setup and initial loading from NAND is -implemented in the X-Loader, so U-Boot is already running in SDRAM -when control is handed over to it. - -The Makefile offers two different configurations to be used if you -boot from Nand or OneNand. - - make nhk8815_config - make nhk8815_onenand_config - -Both support OneNand and Nand.
