2.Run Script File Usage:
- chmod u+x *.sh
- Select the update script
  >> socflash.sh: the firmware is provided by ASPEED, AMI, Avocent
  >> socflsah_elom.sh: the firmware is provided by Quanta
- Run Script
  >> Format1:
     ++ ./socflash.sh [new image] [backup image]
  >> Format2: Update image only
     ++ ./socflash.sh -s [new image]
  >> Format3: Backup old image only
     ++ ./socflash.sh -b [backup image]
3.Run Execution File Usage: (New Command Interface)
- Format:
  >> socflash [operand]
     ++ operand list
     +++ if=the update file
     +++ of=the backup file
     +++ is=the input string
     ++++ blank is not allowed in the string and the length of the string is below than 40 bytes
     ++++ example: is=11:22:33:44:55:66
     +++ bus=PCI device bus number
     +++ cs=chip select
     ++++ AST1000/2000: 0/1 (default: 0)
     ++++ AST1100/2050/2100: 0/1/2
     +++++ default: get from SCU trapping
     ++++++ if Boot Trapping is disabled, then set to 0 for AST2100, and 2 for others
     +++ flashtype=flash chip type
     ++++ 0/1/2/3: NOR/NAND/SPI/SYS SPI Flash
     +++++ SYS SPI: AST2500/2400/1400/2300/1300/1050 only
     +++ width= NOR flash bus width
     ++++ 8/16: AST2400/1400/2300/1300/1050
     ++++ 8   : AST2100/2200
     ++++ 16  : AST2000
     +++ skip=the skip size in bytes at the start of input file (default=0)
     +++ offset=the offset in bytes at the start of the flash (default=0)
     +++ count=the size in bytes copy to the flash (default=the size of the flash)
     +++ backupcount=the size in bytes backup from the flash (default=the size of the flash)
     +++ lpcport=the LPC port number (0x2e/0x4e) (it is required for "option=l")
     +++ writeclk/readclk/eraseclk: SPI Write CLK/Read CLK/EraseCLK
     ++++ writeclk=50	; The Max. SPI Write CLK is 50MHz
     +++ gpio_cs=r2: special options for AST2500 SPI2 use GPIOR2 as CS
     +++ gpio_b/gpio_f=set gpio before/after flash update program execute
     ++++ support chips: AST1100/2050/2100/2150/2200/1300/2300/1400/2400
     ++++ limitation: max. gpio set: 10
     ++++ format:[port+pin+data ....]
     ++++ example: gpio_b=c41a71 means set GPIO C4 to 1, A7 to 1 before program execute
     ++++ example: gpio_f=c40a70 means set GPIO C4 to 0, A7 to 0 after program execute
     +++ reginit_b/reginit_f=Reg. Table File
     ++++ set ARM interface reg. before/after flash update
     ++++ command example: reginit_b=reginit.inf
     ++++ reg. file format: [addr] [mask] [data]
     +++++ ex: 0x1e6e2000 0xffffffff 0x1688a8a8	; write 0x1688a8a8 to 0x1e6e2000
     +++++ notes: skip the command if add ";" at the first of the line
     +++ comport=the com port used
     ++++ only effect for option=u
     +++ baudrate=921600/115200(default)
     ++++ only effect for option=u
     ++++ ex: comport=0
     +++ option=f|c|2|r|d|x|l|i|m
     ++++ f: skip the comparision of flash data and force to update
     ++++ c: use chip erase instead of sector erase
     ++++ r: reset scratch
     ++++ d: disable ARM after update flash
     ++++ 2: two flash update support
     +++++ AST1100/2050/2100: two SPI solution: 1st SPI is on CS2; 2nd SPI is on CS0
     +++++ AST2000: two NOR Flash Solution: 1st Flash is on CS0; 2nd Flash is on CS1
     ++++ x: low speed mode (SPI only)
     +++++ use this option if can' find SPI flash or update properly in normal mode
     ++++ l: Update firmware through LPC path
     +++++ AST2400/1400/2300/1300/1050 only
     ++++ i: Update Firmware Image to Flash only if Image and Flash Size are the same
     ++++ m: Update firmware through co-processor
     +++++ AST2400/1400 + AST1070 only
     ++++ w: Trigget WDT reset only
     ++++ u: Update firmware through UART
     +++++ AST2500 only
     +++++ Running socflash utility on client machine and connect UART port to BMC debug UART port
  >> example:
     ++ socflash if=new.bin of=old.bin option=f
     +++ update the firmware image to new.bin
     +++ bacup the old firmware to old.bin
     +++ force to update without comparision
4.Run Execution File Usage: (Legacy Interface)
- Format:
  >> Normal: SOCFlash [-options] [the update soc file*] [the backup file*] [Chip Select] [Flash Type] [Skip Size] [Programming Size]
  >> Backup Only: SOCFlash -b [the backup file*] [Chip Select] [Flash Type] [Start Offset] [Programming Size]
  >> Skip Backup: SOCFlash -s [the update soc file*] [Chip Select] [Flash Type] [Start Offset] [Programming Size]
     ++ The fields add * means must have
- Options:
  >> Chip Select:
     ++ AST1000/2000: 0/1 (default: 0)
     ++ AST1100/2050/2100: 0/1/2
     +++ default: get from SCU trapping
     ++++ if Boot Trapping is disabled, then set to 0 for AST2100, and 2 for others
  >> Flash Type: (AST1100/2050/2100)
     ++ 0/1/2: NOR/NAND/SPI
  >> Skip Size: Skip size from image start (default: 0x0)
  >> Programming Size: The size need to program to Flash
  >> options:
     ++ b: backup only
     ++ s: skip backup
     ++ f: force to update flash
     ++ 2: special for two SPI support on AST1100/2050/2100
     +++   Boot CS: 2; Secondary CS: 0
- Example: socflash all.bin old.bin
