This list should be updated when more addresses are used. IFC region map from core's view ------------------------------- During boot i.e. IFC Region #1:- 0x30000000 - 0x37ffffff : 128MB : NOR flash 0x38000000 - 0x3BFFFFFF : 64MB : Promjet 0x3C000000 - 0x40000000 : 64MB : FPGA etc After relocate to DDR i.e. IFC Region #2:- 0x5_1000_0000..0x5_1fff_ffff Memory Hole 0x5_2000_0000..0x5_3fff_ffff IFC CSx (FPGA, NAND and others 512MB) 0x5_4000_0000..0x5_7fff_ffff ASIC or others 1GB 0x5_8000_0000..0x5_bfff_ffff IFC CS0 1GB (NOR/Promjet) 0x5_C000_0000..0x5_ffff_ffff IFC CS1 1GB (NOR/Promjet) Booting Options --------------- a) Promjet Boot b) NOR boot c) NAND boot d) SD boot e) QSPI boot Environment Variables --------------------- - mcboottimeout: MC boot timeout in milliseconds. If this variable is not defined the value CONFIG_SYS_LS_MC_BOOT_TIMEOUT_MS will be assumed. - mcmemsize: MC DRAM block size. If this variable is not defined the value CONFIG_SYS_LS_MC_DRAM_BLOCK_MIN_SIZE will be assumed. Booting Linux flavors which do not support 48-bit VA (< Linux 3.18) ------------------------------------------------------------------- One needs to use appropriate bootargs to boot Linux flavors which do not support 48-bit VA (for e.g. < Linux 3.18) by appending mem=2048M, as shown below: => setenv bootargs 'console=ttyS1,115200 root=/dev/ram earlycon=uart8250,mmio,0x21c0600,115200 default_hugepagesz=2m hugepagesz=2m hugepages=16 mem=2048M' X-QSGMII-16PORT riser card ---------------------------- The X-QSGMII-16PORT is a 4xQSGMII/8xSGMII riser card with eighth SerDes interfaces implemented in PCIe form factor board. It supports followings - Card can operate with up to 4 QSGMII lane simultaneously - Card can operate with up to 8 SGMII lane simultaneously Supported card configuration - CSEL : ON ON ON ON - MSEL1 : ON ON ON ON OFF OFF OFF OFF - MSEL2 : OFF OFF OFF OFF ON ON ON ON To enable this card: modify hwconfig to add "xqsgmii" variable.
