| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to accomodate SoCs that come with multiple watchdogs (or any other reset sources of the same kind) add a notion of "reset source instance", similar to what we already have for bootsource API.

To make functions like imx_xload() work consistently across various i.MX platforms use already existent BOOTSOURCE_SPI_NOR constant to mean booting from SPI-NOR on i.MX6 as well.

| * | | | | | ARM: i.MX: phytec-som-imx: Remove kernel and oftree partiton in NANDChristian Hemp2018-04-164-35/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We store kernel and oftree in static UBI volumes now. No need for separate partitions any more. Signed-off-by: Christian Hemp <christian.hemp@gmail.com> Acked-by: Stefan Lengfeld <s.lengfeld@phytec.de>
| * | | | | | clk: i.MX6: Fix enfc_sel for i.MX6dqpSascha Hauer2018-04-161-1/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The plus SoC variants have some differences in the clock controller. For now fix the NAND controller clock. There are more differences that might be relevant, but for now are left for a future excercise. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * | | | | | ARM: i.MX6: Add cpu type for 'plus' variantsSascha Hauer2018-04-124-11/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need to distinguish between the i.MX6d/q and the i.MX6d/q plus SoC variants. Add a cpu type for them to make that possible in the next steps. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * | | | | | ARM: i.MX6: factor out function to read si_revSascha Hauer2018-04-121-25/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The i.MX6sl has another silicon revision register offset than the other i.MX6 SoCs. Finding the register is done twice. Factor out a function to get a common place to find the register. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * | | | | | ARM: i.MX6: de-inline i.MX6 type detectionSascha Hauer2018-04-122-14/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Having the i.MX6 type detection completely inline is less then optimal in terms of binary size. Make the detection functions non-inline. While at it ask the registers only once and store the result in a variable as the i.MX6 type is unlikely to change during runtime.
