[U-Boot] TQM834x CFI flash question: Support for 1 or 2 flash banks?

[Stefan Roese <sr@denx.de>]

Hi Marian,

I'm in the process of cleaning up some of the CFI driver 
defines/implementation hacks, such as CONFIG_SYS_MAX_FLASH_BANKS_DETECT. While 
doing this I noticed that the TQM834x port uses this define and sets it to 2 
(via the tqm834x_num_flash_banks variable) if a 2nd chip is detected. But I 
fail to see how this could really work, since the board port doesn't provide a 
2nd base address via the an entry in the CONFIG_SYS_FLASH_BANKS_LIST define, 
where the probing of the 2nd bank should be done in the common CFI driver.

I know that the board port was done quite some time ago, but perhaps you do 
remember some details. Has this ever been tested with 2 banks on this board? 
If yes, how? Could be that I'm missing something. Please enlighten me. :)

Thanks.

Cheers,
Stefan
