2020-08-17ARM: imx: Add support for switching primary/secondary boot mode to bmodeMarek Vasut
The i.MX6/i.MX7 is capable of booting a secondary "redundant" system image in case the primary one is corrupted. The user can force this boot mode as well by explicitly setting SRC GPR10 bit 30. This can be potentially useful when upgrading the bootloader itself. Expose this functionality to the user.

2020-08-17ARM: imx: Add bmode support for iMX7Marek Vasut
Add the basic differentiation between i.MX6 and i.MX7 into the bmode command, the mechanism really works almost the same on both platforms.

2019-11-03ARM: imx: Fix bmode detection from grp10Claudius Heine
imx6_is_bmode_from_gpr9 always returns false, because IMX6_SRC_GPR10_BMODE is 1<<28 and gets casted to u8 on return. This moves the function body into imx6_src_get_boot_mode, since that is the only one using it and it is on the same abstraction level (accessing registers directly).

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2017-11-27imx: Remove boolean parameter from wdog powerdown functionFabio Estevam
imx_set_wdog_powerdown() is always used to disable the power down enable bit, so remove the boolean parameter of the function. It is also a bit strange to write a boolean value into registers, so this new version makes explicit that we are writing 0. While at it, rename it to imx_wdog_disable_powerdown().

Clear powerdown enable bit for WDOG3 on i.MX6ULL to avoid unwanted kernel reboots. Suggested-by: Ye Li <ye.li@nxp.com> Signed-off-by: Fabio Estevam <fabio.estevam@nxp.com> Reviewed-by: Peng Fan <peng.fan@nxp.com> Reviewed-by: Stefano Babic <sbabic@denx.de>
2017-07-12imx: reorganize IMX code as other SOCsStefano Babic
Change is consistent with other SOCs and it is in preparation for adding SOMs. SOC's related files are moved from cpu/ to mach-imx/<SOC>. This change is also coherent with the structure in kernel.
