2018-02-01board: colibri_imx7: avoid using DDR reserved for Cortex-M42015.04-toradex-next2015.04-toradexStefan Agner
Using linux,usable-memory the board code carves out 1MiB of memory for the Cortex-M4 core at the end of the 256MiB block. However, in case a board has 256MiB of memory (Colibri iMX7S), that is the area where U-Boot gets relocated to... Use board_get_usable_ram_top to avoid using that area as relocation target.

2018-02-01board: colibri_imx7: reserve DDR memory for Cortex-M4Stefan Agner
i.MX 7's Cortex-M4 core can run from DDR and uses DDR memory for the rpmsg communication. Both use cases need a fixed location of memory reserved. For the rpmsg use case the reserved area needs to be in sync with the kernel's hardcoded vring descriptor location. Use the linux,usable-memory property to carve out 1MB of memory in case the M4 core is running. Also make sure that the i.MX 7 specific rpmsg driver does not get loaded in case we do not carve out memory.

2018-02-01Revert "colibri_imx7: print warning about upcoming NAND change"Stefan Agner
This reverts commit 34fcaeec51fa3f519a13eb8d127abea1853e77e5. If you have this version of U-Boot running, the change we warned about has already been applied. No need to warn anymore. Signed-off-by: Stefan Agner <stefan.agner@toradex.com> Acked-by: Marcel Ziswiler <marcel.ziswiler@toradex.com>
2016-09-29colibri_imx7: print warning about upcoming NAND changeStefan Agner
We plan to no longer support the work-around for errata e9609 since it does not allow to detect factory bad blocks. Print a warning to prepare customers of the upcoming change. Signed-off-by: Stefan Agner <stefan.agner@toradex.com> Acked-by: Marcel Ziswiler <marcel.ziswiler@toradex.com>
2016-09-29colibri_imx7: disable DCDC2 dischargeStefan Agner
Disable DCDC2 discharge as this leads to higher power consumption when turning off DCDC2 on Colibri iMX7S. This is likely due to backfeeding the DCDC2 through the VFB2 pin. Signed-off-by: Stefan Agner <stefan.agner@toradex.com> Acked-by: Marcel Ziswiler <marcel.ziswiler@toradex.com>
