Thomas reported U-Boot failed to build host tools if libfdt-devel package is installed because tools include libfdt headers from /usr/include/ instead of using internal ones. This commit moves the header code: include/libfdt.h -> include/linux/libfdt.h include/libfdt_env.h -> include/linux/libfdt_env.h and replaces include directives: #include <libfdt.h> -> #include <linux/libfdt.h> #include <libfdt_env.h> -> #include <linux/libfdt_env.h> Reported-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> |

Overview -------- - BSC9131 is integrated device that targets Femto base station market. It combines Power Architecture e500v2 and DSP StarCore SC3850 core technologies with MAPLE-B2F baseband acceleration processing elements. - It's MAPLE disabled personality is called 9231. The BSC9131 SoC includes the following function and features: . Power Architecture subsystem including a e500 processor with 256-Kbyte shared L2 cache . StarCore SC3850 DSP subsystem with a 512-Kbyte private L2 cache . The Multi Accelerator Platform Engine for Femto BaseStation Baseband Processing (MAPLE-B2F) . A multi-standard baseband algorithm accelerator for Channel Decoding/Encoding, Fourier Transforms, UMTS chip rate processing, LTE UP/DL Channel processing, and CRC algorithms . Consists of accelerators for Convolution, Filtering, Turbo Encoding, Turbo Decoding, Viterbi decoding, Chiprate processing, and Matrix Inversion operations . DDR3/3L memory interface with 32-bit data width without ECC and 16-bit with ECC, up to 400-MHz clock/800 MHz data rate . Dedicated security engine featuring trusted boot . DMA controller . OCNDMA with four bidirectional channels . Interfaces . Two triple-speed Gigabit Ethernet controllers featuring network acceleration including IEEE 1588. v2 hardware support and virtualization (eTSEC) . eTSEC 1 supports RGMII/RMII . eTSEC 2 supports RGMII . High-speed USB 2.0 host and device controller with ULPI interface . Enhanced secure digital (SD/MMC) host controller (eSDHC) . Antenna interface controller (AIC), supporting three industry standard JESD207/three custom ADI RF interfaces (two dual port and one single port) and three MAXIM's MaxPHY serial interfaces . ADI lanes support both full duplex FDD support and half duplex TDD support . Universal Subscriber Identity Module (USIM) interface that facilitates communication to SIM cards or Eurochip pre-paid phone cards . TDM with one TDM port . Two DUART, four eSPI, and two I2C controllers . Integrated Flash memory controller (IFC) . TDM with 256 channels . GPIO . Sixteen 32-bit timers The e500 core subsystem within the Power Architecture consists of the following: . 32-Kbyte L1 instruction cache . 32-Kbyte L1 data cache . 256-Kbyte L2 cache/L2 memory/L2 stash . programmable interrupt controller (PIC) . Debug support . Timers The SC3850 core subsystem consists of the following: . 32 Kbyte 8-way level 1 instruction cache (L1 ICache) . 32 Kbyte 8-way level 1 data cache (L1 DCache) . 512 Kbyte 8-way level 2 unified instruction/data cache (M2 memory) . Memory management unit (MMU) . Enhanced programmable interrupt controller (EPIC) . Debug and profiling unit (DPU) .

NAND Flash 2. SPI Flash Default Boot Method -------------------- NAND boot Building U-Boot -------------- To build the U-Boot for BSC9131RDB: 1. NAND Flash with sysclk 66MHz(J16 on RDB closed, default) make BSC9131RDB_NAND 2. NAND Flash with sysclk 100MHz(J16 on RDB open) make BSC9131RDB_NAND_SYSCLK100 3. SPI Flash with sysclk 66MHz(J16 on RDB closed, default) make BSC9131RDB_SPIFLASH 4. SPI Flash with sysclk 100MHz(J16 on RDB open) make BSC9131RDB_SPIFLASH_SYSCLK100 Memory map ----------- 0x0000_0000 0x7FFF_FFFF DDR 1G cacheable 0xA0000000 0xBFFFFFFF Shared DSP core L2/M2 space 512M 0xC100_0000 0xC13F_FFFF MAPLE-2F 4M 0xC1F0_0000 0xC1F3_FFFF PA SRAM Region 0 256K 0xC1F8_0000 0xC1F9_FFFF PA SRAM Region 1 128K 0xFED0_0000 0xFED0_3FFF SEC Secured RAM 16K 0xFEE0_0000 0xFEE0_0FFF DSP Boot ROM 4K 0xFF60_0000 0xFF6F_FFFF DSP CCSR 1M 0xFF70_0000 0xFF7F_FFFF PA CCSR 1M 0xFF80_0000 0xFFFF_FFFF Boot Page & NAND Buffer 8M DDR Memory map --------------- 0x0000_0000 0x36FF_FFFF Memory passed onto Linux 0x3700_0000 0x37FF_FFFF PowerPC-DSP shared control area 0x3800_0000 0x4FFF_FFFF DSP Private area Out of 880M, passed onto Linux, 1hugetlb page of 256M is reserved for data communcation between PowerPC and DSP core.

Flashing Images --------------- To place a new U-Boot image in the NAND flash and then boot with that new image temporarily, use this: tftp 1000000 u-boot-nand.bin nand erase 0 100000 nand write 1000000 0 100000 reset Using the Device Tree Source File --------------------------------- To create the DTB (Device Tree Binary) image file, use a command similar to this: dtc -b 0 -f -I dts -O dtb bsc9131rdb.dts > bsc9131rdb.dtb Likely, that .dts file will come from here; linux-2.6/arch/powerpc/boot/dts/bsc9131rdb.dts Booting Linux ------------- Place a linux uImage in the TFTP disk area. tftp 1000000 uImage tftp 2000000 rootfs.ext2.gz.uboot tftp c00000 bsc9131rdb.dtb bootm 1000000 2000000 c00000
