- In ARMv8 NXP Layerscape platforms we also need to make use of CONFIG_SYS_RELOC_GD_ENV_ADDR now, do so. - On ENV_IS_IN_REMOTE, CONFIG_ENV_OFFSET is never used, drop the define to 0. - Add Kconfig entry for ENV_ADDR. - Make ENV_ADDR / ENV_OFFSET depend on the env locations that use it. - Add ENV_xxx_REDUND options that depend on their primary option and SYS_REDUNDAND_ENVIRONMENT - On a number of PowerPC platforms, use SPL_ENV_ADDR not CONFIG_ENV_ADDR for the pre-main-U-Boot environment location. - On ENV_IS_IN_SPI_FLASH, check not for CONFIG_ENV_ADDR being set but rather it being non-zero, as it will now be zero by default. - Rework the env_offset absolute in env/embedded.o to not use CONFIG_ENV_OFFSET as it was the only use of ENV_OFFSET within ENV_IS_IN_FLASH. - Migrate all platforms.

Overview ========= C29XPCIE board is a series of Freescale PCIe add-in cards to perform as public key crypto accelerator or secure key management module. It includes C293PCIE board, C293PCIE board and C291PCIE board. The Freescale C29x family is a high performance crypto co-processor. It combines a single e500v2 core with necessary SEC engines. (maximum core frequency 1000/1200 MHz). The C29xPCIE board features are as follows: Memory subsystem: - 512Mbyte unbuffered DDR3 SDRAM discrete devices (32-bit bus) - 64 Mbyte NOR flash single-chip memory - 4 Gbyte NAND flash memory - 1 Mbit AT24C1024 I2C EEPROM - 16 Mbyte SPI memory Interfaces: - 10/100/1000 BaseT Ethernet ports: - eTSEC1, RGMII: one 10/100/1000 port - eTSEC2, RGMII: one 10/100/1000 port - DUART interface: - DUART interface: supports two UARTs up to 115200 bps for console display Board connectors: - Mini-ITX power supply connector - JTAG/COP for debugging Physical Memory Map on C29xPCIE =============================== Address Start Address End Memory type 0x0_0000_0000 - 0x0_1fff_ffff 512MB DDR 0xc_0000_0000 - 0xc_8fff_ffff 256MB PCIE memory 0xf_ec00_0000 - 0xf_efff_ffff 64MB NOR flash 0xf_ffb0_0000 - 0xf_ffb7_ffff 512KB SRAM 0xf_ffc0_0000 - 0xf_ffc0_ffff 64KB PCIE IO 0xf_ffdf_0000 - 0xf_ffdf_0fff 4KB CPLD 0xf_ffe0_0000 - 0xf_ffef_ffff 1MB CCSR Serial Port Configuration on C29xPCIE ===================================== Configure the serial port of the attached computer with the following values: -Data rate: 115200 bps -Number of data bits: 8 -Parity: None -Number of Stop bits: 1 -Flow Control: Hardware/None Settings of DIP-switch ====================== SW5[1:4]= 1111 and SW5[6]=0 for boot from 16bit NOR flash SW5[1:4]= 0110 and SW5[6]=0 for boot from SPI flash Note: 1 stands for 'off', 0 stands for 'on' Build and program U-Boot to NOR flash ================================== 1. Build u-boot.bin image example: export ARCH=powerpc export CROSS_COMPILE=/your_path/powerpc-linux-gnu- make C293PCIE 2. Program u-boot.bin into NOR flash => tftp $loadaddr $uboot => protect off eff40000 +$filesize => erase eff40000 +$filesize => cp.b $loadaddr eff40000 $filesize 3. Check SW5[1:4]= 1111 and SW5[6]=0, then power on. Alternate NOR bank ================== There are four banks in C29XPCIE board, example to change bank booting: 1. Program u-boot.bin into alternate NOR bank => tftp $loadaddr $uboot => protect off e9f40000 +$filesize => erase e9f40000 +$filesize => cp.b $loadaddr e9f40000 $filesize 2. Switch to alternate NOR bank => cpld_cmd reset altbank [bank] - [bank] bank value select 1-4 - bank 1 on the flash 0x0000000~0x0ffffff - bank 2 on the flash 0x1000000~0x1ffffff - bank 3 on the flash 0x2000000~0x2ffffff - bank 4 on the flash 0x3000000~0x3ffffff or set SW5[7]= ON/OFF and SW5[7]= ON/OFF, then power on again. Build and program U-Boot to SPI flash ================================== 1. Build u-boot-spi.bin image make C29xPCIE_SPIFLASH_config; make Need the boot_format tool to generate u-boot-spi.bin from the u-boot.bin. 2. Program u-boot-spi.bin into SPI flash => tftp $loadaddr $uboot-spi => sf erase 0 100000 => sf write $loadaddr 0 $filesize 3. Check SW5[1:4]= 0110 and SW5[6]=0, then power on.
