[U-Boot-Users] help,copy vector--->ram

[apciy]

hello everyone:)
    i am learning the u-boot-1.1.3 .
    i got a question about copying the vector to the ram,the following is the piece of code.
the path :u-boot/u-boot-1.1.3/cpu/s3c44b0/start.s

****************************************************************
/*
    now copy to sram the interrupt vector
*/
    adr    r0, real_vectors
    add    r2, r0, #1024
    ldr    r1, =0x0c000000
    add    r1, r1, #0x08
vector_copy_loop:
    ldmia    r0!, {r3-r10}
    stmia    r1!, {r3-r10}
    cmp    r0, r2
    ble    vector_copy_loop
*****************************************************************

a) "add r2,r0,#1024"
    is the real_vectors size 1024 byte? how and where to define it?

b) what will happend if there is not the command "add r1,r1,#0x08"? the first ASM command of real_vectors in the ram begin from 0x0c000000 or 0x0c000008? i think it should be at the 0x0c000000,but it looks the 0x0c000008 is correct...so i lost :(

thanks all of you:)
