[U-Boot-Users] IXDP size comments and board reset issue

[U-Boot-Users] IXDP size comments and board reset issue

[Ara Avanesyan]

Hi all,

i am confused by the following comments:
1. board/ixdp425/flash.c
 switch (value) {

 case (FPW) INTEL_ID_28F128J3A:
  info->flash_id += FLASH_28F128J3A;
  info->sector_count = 128;
  info->size = 0x02000000;
  break;  /* => 16 MB     */

the comment shows 16 mb (correctly) while it's assigned 32 mb

2. configs/ixdp425.h
/*
 * Physical Memory Map
 */
#define CONFIG_NR_DRAM_BANKS    1          /* we have 2 banks of DRAM */

defined 1 but commented 2 banks.

am i missing something?

Also I have another issue regarding to reset.
After linux reboot, it calls hardware reset (arch_reset). My board hangs. 
The same linux build resets fine with RedBoot. Is there anything specific 
here? (i do not have debugger to debug it myself :( )

Thanks!
Ara

Actually, it's the comment updating later than code.
In this case, try to believe yourself. Most cases, I
perfer to believe code itself rather than comment:-)

No, the writer was too busy to synchronize them.

Well, an uneducated hint. Could you define
CFG_RESET_ADDRESS in <YOUR-BOARD.h> ?

Oh, seems I figured out what's the problem. That is, after ixdp reset the 
flash is not resetted and is in undefined state. There is a good discussion 
about this topic at arm-linux mailing list.
One needs to manually reset flash somewhere before the arch_reset function.

Hey I got u-boot running on avila board, i'll soon write a small description 
of how i ported it.
