[U-Boot-Users] [PATCH] Running from SDRAM Detection on omap1510inn

[Michael Bendzick]

Included is a patch that improves the detection scheme in platform.S that
the omap1510inn build uses to determine whether or not it is running from
SDRAM.  The result of the detection is used to determine if the SDRAM
configuration registers are safe to change.

The previous implementation only made a distinction between running from
Flash at 0x0 or SDRAM at 0x10000000.  This patch allows U-Boot to run from
internal SRAM at 0x20000000 as well and still realize that it can safely
configure external SDRAM.

Attention 1610 Innovator Users/Owners:  Please give this patch a try on your
boards as well, as it should work exactly the same.

Change log snippet:

* Patch by Michael Bendzick, 30 Aug 2004:
  - Improve platform.S code for omap1510inn that detects whether code
    is running from SDRAM or not.  Patch allows SDRAM to be configured
    if code is running out of SRAM at 0x20000000.
