I.MX6 solo/dual lite register map differs from i.mx6 dual/quad

[jfsimon]

Hi,

I was surprised to see that the register map address of I.MX6 solo/dual lite is different from I.MX6 dual/quad.

Maybe I have overlooked something in Freescale documentation, but I didn't see any mentions of that in the docs.

For example looking at the IOMUX register map for PAD SD2_DATA1, I see different addresses:

    From i.MX 6Solo/6DualLite Applications Processor Reference Manual, Rev. 0, 11/2012:

        20E_06E8 Pad Control Register          (IOMUXC_SW_PAD_CTL_PAD_SD2_DATA1)

    From i.MX 6Dual/6Quad Applications Processor Reference Manual, Rev. 0, 11/2012

        20E_0360 Pad Control Register          (IOMUXC_SW_PAD_CTL_PAD_SD2_DATA1)

As for u-boot I can see that only the I.MX6 dual/quad is supported. (from arch/arm/include/asm/arch-mx6/mx6x_pins.h)

MX6Q_PAD_SD2_DAT1__USDHC2_DAT1          = IOMUX_PAD(0x0360, 0x004C, 0, 0x0000, 0, 0),

Am I confused?

If not, is there somewhere a summary of differences? I am worried having to go through the 5000 or so pages of the manual.

Thx a lot,

U-boot supports mx6q, dual, dual-lite, solo, solo-lite variants.

Take a look at sabresd board, which supports quad and dual lite variants:

uboot-imx.git - Freescale i.MX u-boot Tree

There is also mx6sl_evk:
