[U-Boot-Users] TRAB: Flash Am29LV320DB confusion

[triloksoni <trilok.soni@emuzed.com>]

Hi All,

I was just going through the "flash.c" code of TRAB board. Which is having
AM29LV320D (2M x 16bit)  flash chip. We are also going to use the same chip
for our new board in 16bit mode.

Confusion is in flash_init(...) code. As per the sector architecture 
mentioned in
the datasheet : Eight 8 Kbytes sector and Sixty Three 64Kbytes sectors. 
Then why this code has
mentioned remaining sector size as 128Kbytes :

board/trab/flash.c:
--------------snip-------------------------
                        switch (info->flash_id & FLASH_TYPEMASK) {
                        case (FLASH_AM320B & FLASH_TYPEMASK):
                        case (FLASH_MXLV320B & FLASH_TYPEMASK):
                                /* Boot sector type: 8 x 8 + N x 128 kB */
                               /* Why N x 128 kB?? It should be N x 64 
kB. */
                                flashbase += (j < 8) ? 0x4000 : 0x20000;
                                break;

Am I missing something ???
