[PATCH v2] can: flexcan: remove HAVE_CAN_FLEXCAN Kconfig symbol

[PATCH v2] can: flexcan: remove HAVE_CAN_FLEXCAN Kconfig symbol

[Marc Kleine-Budde]

This patch removes the Kconfig symbol HAVE_CAN_FLEXCAN from arch/{arm,powerpc}
and allowing compilation unconditionally on all arm and powerpc platforms.

This brings a bigger compile time coverage and removes the following dependency
warning found by Arnd Bergmann:

    warning: (SOC_IMX28 && SOC_IMX25 && SOC_IMX35 && IMX_HAVE_PLATFORM_FLEXCAN &&
        SOC_IMX53 && SOC_IMX6Q) selects HAVE_CAN_FLEXCAN
    which has unmet direct dependencies (NET && CAN && CAN_DEV)

Changes since v1:
- don't remove IMX_HAVE_PLATFORM_FLEXCAN, which breaks non DT imx platforms

Thanks.

An Acked-by by the powerpc people would be fine. However, if nobody
doesn't object, I'm sending this patch via linux-can and net-next upstream.

regards,
Marc

Sorry, missed it, if it's still out there, add my
