What is size and NAND_BLOCK_MASK at this time?

i use the code uboot/cpu/arm920t/s3c24x0/nand_read.c.
i write this in my code: nand_read_ll(buf,0x32000000,sizeof(buf));
this part of nand_read_ll:
for (i=start_addr; i < (start_addr + size);) {
if (i % NAND_BLOCK_SIZE == 0) {
if (is_bad_block(i) ||
is_bad_block(i + NAND_PAGE_SIZE)) {
orange_on(1);-----------------------------it's always run here code.
i += NAND_BLOCK_SIZE;
size += NAND_BLOCK_SIZE;
continue;
}
}
blue_on(1);------------------------------------never execute here code.
j = nand_read_page_ll(buf, i);
i += j;
/* buf += j;*/
}
the orange_on(1) and blue_on(1) write by me, that mean orange led on the
parameter is blink times.
For serial console debug, it's still a question about how to write to
the serial device?
i want use serial console debug, but i still have no ideas about serial
console ,
later will be better :-)
