[U-Boot] fsl_elbc_nand bug

[Andrei Yakimov]

Hi, 
 I just found, if NAND ONFI parameter page first copy is 
bad, u-boot will never read extra copes: 

fsl_elbc_nand.c: 
 342                 out_be32(&lbc->fbcr, 256);  
 343                 ctrl->read_bytes = 256;

this code cause "read beyond buffer" error message:
 
nand_base.c:
   chip->cmdfunc(mtd, NAND_CMD_PARAM, 0, -1);
3243         for (i = 0; i < 3; i++) {
3244                 for (j = 0; j < sizeof(*p); j++)
3245                         ((uint8_t *)p)[j] = chip->read_byte(mtd);
3246                 if (onfi_crc16(ONFI_CRC_BASE, (uint8_t *)p, 254) ==
3247                                 le16_to_cpu(p->crc)) {
3248                         break;
3249                 }
3250         }

Unfortunately I do not working with latest u-boot now,
so can not provide a patch,  read size should be increased to
at least 768 ( 3 copy mandatory for ONFI spec). Linux kernel should be
updated too.

I am also not expert for other NAND controllers drivers.

But first copy of ONFI parameter page CAN GO BAD. I seen it my self.
