本source code 為s3c4510的bootloader

1.  ROM and RAM startup tests (with S3C4530 support).
1.1 Build test using ADS v1.1 development tools.

Project must include foolowing files:

    init.s
    isr.c
    memory.c
    pollio.c
    timer.c
    uart.c
    main.c
    iic.c
    dma.c
    iop.c
    mac.c
    macinit.c
    system.c
    Hdlcmain.c
    Hdlc100init.c
    crctab.c
    zmodem.c
    zmodemt.c
    zmodemr.c
    zmutil.c
    zmport.c

    Assembler Command Line (ROM Startup) (ADS v1.1):
    -keep -PD "ROM_AT_ADDRESS_ZERO SETL {TRUE}" -liston -g 
    -width 120 -fpu None

    C Compiler Command Line(ROM & RAM Startup) (ADS v1.1):
    -fpu None -O0 -Ono_inline -g+ -apcs /ropi -W+gitu -D_S3C4530_ 
    -D__TARGET_FPU_NONE -DLITTLE -D__APCS_ROPI

    Linker Command Line (ROM Startup) (ADS v1.1):
    -noremove  -info totals -info unused -ro-base 0x0 -mangled -map -symbols 
    -verbose -first init.o(Init) -info veneers -info sizes -xref

    Assembler Command Line (RAM Startup) (ADS v1.1):
    -keep -liston -g -width 120 -fpu None

    Linker Command Line (RAM Startup) (ADS v1.1):
    -noremove  -info totals -info unused -ro-base 0x00800000 -mangled -map 
    -symbols -verbose -first init.o(Init) -info veneers -info sizes -xref

1.2 Build test using GNU development tool 

    gnu/test/Makefile 		- GNU make file 
    gnu/test/evm50100.lds	- GNU linker script 

	init_gnu.S  		- test startup code for GNU assembler
	init_gnu.h   		- include file for init_gnu.S

    Other "C" files are the same:

	isr.c
	memory.c
	pollio.c
	timer.c
	uart.c, 
	main.c
	iic.c
	dma.c
	iop.c
	mac.c
	macinit.c
	system.c
	Hdlcmain.c
	Hdlc100init.c
	crctab.c
	zmodem.c
	zmodemt.c
        zmodemr.c
	zmutil.c
	zmport.c

    To compile test using GNU development tools type:
	cd ./gnu/test
        make 

2.  Monitor (smon-1.x.rom) (with S3C4530 support)
2.1 Compile monitor using ADS v1.1 development tools.

    Project include foolowing files:
    init.s
    load.c

    Assembler Command Line (Monitor) (ADS v1.1):
    -keep -PD "ROM_AT_ADDRESS_ZERO SETL {TRUE}" -liston -g 
    -width 120 -fpu None -PD "LED_ONLY SETL {TRUE}"

    C Compiler Command Line (Monitor) (ADS v1.1):
    -fpu None -O0 -Ono_inline -g+ -W+gilstu -D_S3C4530_ -D__TARGET_FPU_NONE 
    -DLITTLE

    Linker Command Line (Monitor) (ADS v1.1):
    -noremove  -info totals -info unused -ro-base 0x0 -mangled -map -symbols 
    -rw-base 0x3FE0000 -first init.o(Init) -info veneers -info sizes -xref

2.2 Build monitor using GNU development tools 

    gnu/loader/Makefile		- GNU make file 
    gnu/loader/loader.lds	- GNU linker script 
    
	init_gnu.S  		- startup code for GNU assembler
	init_gnu.h   	 	- include file for init_gnu.S

    File load.c is the same.

    To compile loader using GNU development tools type:
	cd ./gnu/loader
        make 

3.  To port test to you board modify hardware settings in 
    file evm50100.a (ADS development tools) or in init_gnu.h
    (GNU development tool). 
    
    If in you board PHY device has address other then 0x01, then  
    modify constant PHYHWADDR in file mac.h, bits 9:5 of this 
    constant contain the 5-bit address of the PHY device.
