Hallo All!
My new IXDP425 board has only 128Mb of RAM, but native IXDP425 has 256Mb
of RAM.
What changes i need does, for porting redboot from IXDP425 with 256Mb of
RAM, to IXDP425 with 128Mb of RAM.

There are two places, I believe. First, the SDRAM controller needs to be
properly setup. The SDRAM controller setup is defined in:
hal/arm/xscale/ixdp425/current/include/ixdp425.h
Next are ram-size entries in the mem config files in:
hal/arm/xscale/ixdp425/current/include/pkgconf/*.{h,ldi}

Has there been any discussion on support for the IXP465 processor - the new
version of the IXP425. On preliminary reading, the interesting features are
a) DDR RAM
b) Integrated USB host controller
c) integrated ethernet MACs
http://www.intel.com/design/network/products/npfamily/ixp465.htm
Thanks
Krishna

I did change in
hal/arm/xscale/ixdp425/current/include/ixdp425.h:
#define CYGMEM_REGION_ram_SIZE (0x8000000)
#define CYGMEM_SECTION_heap1_SIZE (0x8000000 - (size_t)
CYG_LABEL_NAME (__heap1))
hal/arm/xscale/ixdp425/current/include/ixdp425.ldi:
ram : ORIGIN = 0, LENGTH = 0x8000000
hal/arm/xscale/ixdp425/current/include/ixdp425.h:
#define SDRAM_SIZE 0x8000000
Next macros i doesn't change in
.hal/arm/xscale/ixdp425/current/include/ixdp425.h:
#define SDRAM_PHYS_BASE 0x00000000
#define SDRAM_BASE 0x00000000
#define SDRAM_ALIAS_BASE 0x10000000
#define SDRAM_UNCACHED_BASE 0x20000000
#define SDRAM_DC_BASE 0x30000000
Maybe i need change something here?

I have a port to the IXDP465 development platform. I intend to commit
it to CVS in the near future.
