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?

Re: [U-Boot] [PATCH][v2] powerpc/T1040EMU: Add T1040 emulator support

2013-11-11 Thread Priyanka Jain

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

[U-Boot] [PATCH][v2] powerpc/T1040EMU: Add T1040 emulator support

2013-10-28 Thread Priyanka Jain

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
