Are these NFC revision numbers for Freescale Power Architecture devices, such
as MPC5121?
This is how the Freescale kernel names the NFC for different i.MX devices:
CONFIG_ARCH_MXC_HAS_NFC_V2_1 (For MX25 and MX35)
CONFIG_ARCH_MXC_HAS_NFC_V3_1 (For MX37)
CONFIG_ARCH_MXC_HAS_NFC_V3_2 (For MX51)
CONFIG_ARCH_MXC_HAS_NFC_V1 (For MX27 and MX31)
Regards,
Fabio Estevam
