Hi,
Dependency of below patch marked under --- [U-Boot] powerpc/t1040qds: Add DDR Raw Timing support http://patchwork.ozlabs.org/patch/286112/ no longer holds true as thi patch has been deferred.
But below emulator patch will work as it is with SPD method. No changes required.
Regards Priyanka

Add emulator support for T1040. Emulator has limited peripherals and interfaces. Difference between T1040QDS and emulator includes: -ECC for DDR is disabled due to procedure to load images -Depends on raw timing for DDR initialization -No board FPGA (Qixis) -No PCI -No SPI -No flash support

Changes for v2: Incorporated Wolfgang Denk's review comments
Based on u-boot-mpc85xx/next branch. This patch depends upon following patches: 1)[U-Boot] powerpc/t1040qds: Add DDR Raw Timing support http://patchwork.ozlabs.org/patch/286112/ 2)[U-Boot] powerpc/t1040qds: Correct Maintainer name in boards.cfg http://patchwork.ozlabs.org/patch/286113/

This T1040EMU.h should merge with T1040QDS.h and only host the difference, like the way we did for T4240QDS and T4240EMU.

Why do you set the size to a fixed value if using SPD?
