uBoot iMX6 Quad versus Dual (differentiation)

[juliocruz]

Hi All,

I have two boards:

1. QUAD with 2GB DDR3
2. DUAL with 1GB DDR3

I would like to create a unified u-boot that could setup/config the RAM in SPL stage.

My question is: there is a way to know if the board have a QUAD or DUAL?

The function "get_cpu_rev" does not help too much. Additionally, the current header definitions seems no have the dual:

#define MXC_CPU_MX51		0x51
#define MXC_CPU_MX53		0x53
#define MXC_CPU_MX6SL		0x60
#define MXC_CPU_MX6DL		0x61
#define MXC_CPU_MX6SOLO		0x62
#define MXC_CPU_MX6Q		0x63

Thanks
