Re: [U-Boot] [PATCH] ARMV7: OMAP4: Calculate SDRAM size

      Dear "V, Aneesh",

I think you are referring to SDRAM initialization. Yes, it is assumed
that SDRAM initialization(at least the DMM part of it) is done before
the call to sdram_size(). The right location for this seems
to be the initial part of sdram_init().
If you have to deal with boards which may come with different memory
sizes, these may need different initializations. I don't know your
hardware - you may or may not be able to read the needed configuration
from the hardware. Eventually you need to try out different
configurations, in which case the SDRAM initialization has to be part
of the RAM initialization code (as it has to be retried for each
possible configuration).
Best regards,
Wolfgang Denk
