2019-04-13colibri_imx6: revert fuse value set in mfgr_fuseMax Krummenacher
We have two commands to change the bootmode fuses: mfgr_fuse which set fuse 0/5 and 0/6 and updt_fuse which burns bit 4 of 0/5. Before Image 2.6 we fused in mfgr_fuse 0x5062, which boots from the user partition of the eMMC. To workaround certain hangs we moved to fastboot mode and using the first bootpartition of the eMMC requiring a fuse value of 0x5072 which could be achived by the then added updt_fuse command. At the same time the mfgr_fuse command was changed to also fuse 0x5072, revert that second change so that one can fuse both values, one with just mfgr_fuse and the later with mfgr_fuse;updt_fuse. Note that the mfgr_fuse command is only needed at module production time, a customer might need to use updt_fuse when upgrading an older module to be compatible with a newer image. The command is integrated into the image update scripts.

2019-04-13colibri imx6: disable ri and dcd irq in uartsMax Krummenacher
If the UART is used in DTE mode the RI and DCD bits in UCR3 become irq enable bits. Both are set to enabled after reset and both likely are pending. Disable the bits also on UARTs not used in the boot loader to prevent an interrupt storm when Linux enables the UART interrupts.

2018-10-09colibri_imx7: prime get_ram_size() using imx_ddr_size()Fabio Estevam
Rather than passing a hardcoded maxsize to the generic get_ram_size() function use the i.MX 7 specific imx_ddr_size() function, which extracts the memory size at runtime by reading the DDR controller registers. This is a purely cosmetic change as the generic get_ram_size() function already took care of properly automatically detecting 256MB, 512MB or 1GB modules.

This makes sure that all Colibri iMX7 modules work with the same timing. The changes are: - Disable ODT on read (JEDEC standard JESD79-3F says in chapter 5.2.3 ODT during Reads: "As the DDR3 SDRAM can not terminate and drive at the same time, RTT must be disabled at least half a clock cycle..." and also MX7D SABRESD is disabling it) This alone fixed memory issues for two Colibri iMX7 1GB modules which showed issues before - Make sure tRFC(min) is at least 260ns - Make sure tRC is >50.625ns - tRP needs to be >13.125ns, we can lower from 18.75ns to 15ns - tFAW is not relevant, leave at reset Signed-off-by: Stefan Agner <stefan.agner@toradex.com> Acked-by: Marcel Ziswiler <marcel.ziswiler@toradex.com>

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>
