[ECOS] redboot autodetect flash device ?

[ECOS] redboot autodetect flash device ?

[Manfred Gruber]

hi !

I use redboot v2.0, is there any newer code for detecting the flash device?

I want to detect several AMD flash chips. It is enough for me if only the size 
will be detected, because i want to use same types, with different size.
The flash chips will also be placed in the same way on my hardware.

Maybe there is some code or information for me in newer cvs? versions ?

thanks regards manfred

Not in the trunk, but in the flash_v2 branch there is a new AMD driver
which supports CFI. Hence it can adapt at run-time to any
AMD-compatible flash device.

hi !

ok thanks, i will try to switch to cvs version.
eric: thanks also for the point about u-boot.
i will look what is easer for me to switch :-)

what is then the best and correct way to give the start-addresse and size to 
the linux kernel, to start up physmap_configure() ? a command line, ATAG? or 
what, i don't know?
now i have enabled redboot partition parsing which works wonderfull... i have 
6 partions on my flash which i don't want to do over commandline, so redboot 
partition parsing would be fine :-)

thanks regards  manfred
