Overview -------- The LS2080A Development System (QDS) is a high-performance computing, evaluation, and development platform that supports the QorIQ LS2080A Layerscape Architecture processor. The LS2080AQDS provides validation and SW development platform for the Freescale LS2080A processor series, with a complete debugging environment. LS2080A SoC Overview -------------------- Please refer arch/arm/cpu/armv8/fsl-layerscape/doc/README.soc for LS2080A SoC overview. LS2080AQDS board Overview ----------------------- - SERDES Connections, 16 lanes supporting: - PCI Express - 3.0 - SGMII, SGMII 2.5 - QSGMII - SATA 3.0 - XAUI - XFI - DDR Controller - Two ports of 72-bits (8-bits ECC) DDR4. Each port supports four chip-selects and two DIMM connectors. Support is up to 2133MT/s. - One port of 40-bits (8-bits ECC) DDR4 which supports four chip-selects and two DIMM connectors. Support is up to 1600MT/s. -IFC/Local Bus - IFC rev. 2.0 implementation supporting Little Endian connection scheme. - One in-socket 128 MB NOR flash 16-bit data bus - One 512 MB NAND flash with ECC support - IFC Test Port - PromJet Port - FPGA connection - USB 3.0 - Two high speed USB 3.0 ports - First USB 3.0 port configured as Host with Type-A connector - Second USB 3.0 port configured as OTG with micro-AB connector - SDHC: PCIe x1 Right Angle connector for supporting following cards - 1/4-/8-bit SD/MMC Legacy CARD supporting 3.3V devices only - 1-/4-/8-bit SD/MMC Card supporting 1.8V devices only - 4-bit eMMC Card Rev 4.4 (1.8V only) - 8-bit eMMC Card Rev 4.5 (1.8V only) - SD Card Rev 2.0 and Rev 3.0 - DSPI: 3 high-speed flash Memory for storage - 16 MB high-speed flash Memory for boot code and storage (up to 108MHz) - 8 MB high-speed flash Memory (up to 104 MHz) - 512 MB low-speed flash Memory (up to 40 MHz) - QSPI: via NAND/QSPI Card - 4 I2C controllers - Two SATA onboard connectors - UART - Two 4-pin (HW control) or four 2-pin (SW control) serial ports at up to 115.2 Kbit/s - Two DB9 D-Type connectors supporting one Serial port each - ARM JTAG support Memory map from core's view ---------------------------- 0x00_0000_0000 .. 0x00_000F_FFFF Boot Rom 0x00_0100_0000 .. 0x00_0FFF_FFFF CCSR 0x00_1800_0000 .. 0x00_181F_FFFF OCRAM 0x00_3000_0000 .. 0x00_3FFF_FFFF IFC region #1 0x00_8000_0000 .. 0x00_FFFF_FFFF DDR region #1 0x05_1000_0000 .. 0x05_FFFF_FFFF IFC region #2 0x80_8000_0000 .. 0xFF_FFFF_FFFF DDR region #2 Other addresses are either reserved, or not used directly by U-Boot. 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.
