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

Priyanka Jain Priyanka.Jain at freescale.com
Mon Oct 28 11:23:30 CET 2013


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
