Default environment will be used for secure boot flow which can't be edited or saved. 2. Command for secure boot is predefined in the default environment which will run on autoboot (and autoboot is the only option allowed in case of secure boot) and it looks like this: #define CONFIG_SECBOOT \ "setenv bs_hdraddr 0xe8e00000;" \ "esbc_validate $bs_hdraddr;" \ "source $img_addr;" \ "esbc_halt;" #endif 3. Boot Script can contain esbc_validate commands and bootm command. Uboot source command used in default secure boot command will run the bootscript. 4. Command esbc_halt added to ensure either bootm executes after validation of images or core should just spin.

v0.10.2 From 66869f955417b89dbf6b7cbb72738b2205a26bf8 Mon Sep 17 00:00:00 2001 From: York Sun Date: Thu, 19 Mar 2015 09:30:26 -0700 Subject: drivers/ddr/fsl: Update DDR driver for DDR4 Add/update registers for DDR4, including DQ mappings. Allow raw timing method used for all controllers. Update mode_9 register to 0x500 for improved stability. Check DDR controller version number individually in case a SoC has multiple DDR controllers of different versions. Increase read-write turnaround for DDR4 high speeds.

Move them out of common header file and placed into respective board header files. Move TEXTBASE to 1MB offset to fit NOR flash with up to 1MB sector size. Enable command auto complete. Update prompt symbol. Set fdt_high to 0xa0000000 because Linux requires that the fdt be 8-byte aligned and below 512 MiB. Besides ensuring compliance with the 512 MiB limit, this avoids problems with the dtb being misaligned within the FIT image. Change the MC FW, MC DPL and Debug server NOR addresses in compliance with the NOR flash layouts for 128MB flash. Add PCIe macros. Enable "loadb" command. Disable debug server. Enable workaround for erratum A008511. Stop reset on panic for postmortem debugging.

Change ethernet interface name to DPNI. Update entry criteria for ldpaa_eth_stop. Ethernet stack first stop the device before performing next operation. At the time of Ethernet driver registration, net_dev->state is set as ETH_STATE_INIT So take care net_dev->state as ETH_STATE_INIT in ldpaa_eth_stop. Undef CONFIG_PHYLIB temorarily because ldpaa_eth driver currently does not support PHYLIB. Instead of clearing pull descriptor one time, clear it before issuing any volatile dequeue command. Volatile command does not return frame immidiately, wait till a frame is available in DQRR. This frame can be valid or expired. Flush buffer before releasing to BMan ensure the core does not have any cachelines that the WRIOP will DMA to.

RUNTIME registers are defined in PAGE1 and controls NAND and GPCM funcinality. FCM and RUNTIME structures defination is common for IFC version 1.4 and 2.0.
