2.2 uboot相关日志

U-Boot 2016.092.0+g199df35 (Nov 20 2016 - 12:55:53 +0800)

CPU:   Freescale LayerScape LS1021E, Version: 2.0, (0x87081120)  CPU为飞思卡尔的layerscape LS1021E芯片，不是LS1021A吗？ print_cpuinfo(),arch/arm/cpu/armv7/ls1021xa/cpu.c,CONFIG_DISPLAY_CPUINFO,涉及到系统版本寄存器SVR(system version register),从寄存器中读取了various personality字段，字段中的值为0x11,表示LS1021A 芯片，E表示带有安全模块的LS1021A芯片

Clock Configuration:

CPU0(ARMV7):1000 MHz, CPU0的频率被配置为1000MHz,那么CPU1怎么没被配置，难道并没有使用它?需要确认 ，print_cpuinfo()

Bus:300  MHz, DDR:800  MHz (1600 MT/s data rate), 总线频率为300MHz,DDR频率为800MHz,1600 MT/s表示每秒1600兆次数据传输，反映单位时间内的传输速度，T表示Times,为什么是1600，因为HT是双向传输，所以除以2就是单向传输的速率，也就是频率800MHz,HT表示端到端总线技术，即HyperTransport print_cpuinfo()

Reset Configuration Word (RCW):   重置配置字，是芯片复位之后在程序执行过程中需要使用到的硬件配置信息，包括系统时钟、DDR时钟、serdes配置、启动方式、GPIO复用配置等,RCW存储在flash或sd卡的何处呢?这个需要查看芯片手册中的Starting Address，print_cpuinfo()，以下是RCW状态寄存器的信息，一共有16个这样的寄存器，一个寄存器4个字节，那么16个这样的寄存器就是4*16*8 = 512 bit

00000000: 0608000a 00000000 00000000 00000000

00000030: 00080000 481b7340 00000000 00000000

Model: LS1021A TWR Board  型号为LS1021A TWR Board  ,这个值是从device tree中获得，show_board_info(),获取的标记为model;

Board: LS1021ATWR 板子为LS1021ATWR checkboard(),board/freescale/ls1021/atwr/ls1021atwr.c

CPLD:  V3.0  复杂可编程逻辑器件(Complex Programmable Logic Device),cpld_show(),board/freescale/ls1021/atwr/ls1021atwr.c

PCBA:  V2.0 指已经在PCB空板上贴片好所有元器件的板子(PCB Assembly), cpld_show()

VBank: 0   vbank是一个寄存器名字，属于CPLD上的寄存器，用来表明选择的是flash的哪个bank,此处选择的是bank0,寄存器的bit[0]来表示bank的范围，因此此bit只有两个值，0表示从bank0（upper bank）启动,1表示从bank1(lower bank)启动, cpld_show()

I2C:   ready   I2C准备妥当(Inter-Integrated Circuit) ，init_func_i2c(),common/board_f.c,初始化i2c,该函数被填充到init_sequence_f数组中

DRAM:  1 GiB  内存为1GiB(Dynamic Random Access Memory)  dram_init(),board/freescale/ls1021atwr/ls1021atwr.c,“DRAM:“由announce_dram_init（）输出， show_dram_config()输出内存大小,common/board_f.c

Using SERDES1 Protocol: 48 (0x30)   使用SERDES1协议,是一种时分多路复用（TDM:Time Division Multiplexing）、点对点（P2P:Point to Point）的串行通信技术，（Serializer/Deserializer串行器解串器），serdes_init(),arch/arm/cpu/armv7/fsl_lsl_serdes.c,0x30从LS1021ARM.pdf中可以得知其表明支持的网络协议为:PCIe1(x1)、SATA1、SGMII1、SGMII2

Firmware 'Microcode version 0.0.1 for LS1021a r1.0' for 1021 V1.0  固件，u_qe_upload_firmware(),drivers/qe/qe.c 上传微代码到指令RAM的指定地址，详情查看docs/README.qe_firmware中针对QE微代码上传的信息;

QE: uploading microcode 'Microcode for LS1021a r1.0' version 0.0.1 上传微代码？什么意思?需要确认（QUICC Engine），qe_upload_microcode(),drivers/qe/qe.c,属于qe_upload_firmware中的worker函数，实际做的就是上传微代码;

Flash: 128 MiB flash大小为128MiB，这个远程开发板上还插着一个320GiB的硬盘

MMC:   FSL_SDHC: 0 插着一个容量为16GiB的sd卡，实际容量14.5 GiB
