* ARM: mx6: Add function to set serial#Sean Anderson2021-03-011-0/+37
| | | | | | | | | The serial number OTP is similar to the imx7 version, except that the register names are different. This also sets serial# directly, instead of providing board_get_serial. Signed-off-by: Sean Anderson <sean.anderson@seco.com> Reviewed-by: Tom Rini <trini@konsulko.com>
* dm: Rename U_BOOT_DEVICE() to U_BOOT_DRVINFO()Simon Glass2021-01-051-1/+1
| | | | | | | | | | | | | | | | | | | | The current macro is a misnomer since it does not declare a device directly. Instead, it declares driver_info record which U-Boot uses at runtime to create a device. The distinction seems somewhat minor most of the time, but is becomes quite confusing when we actually want to declare a device, with of-platdata. We are left trying to distinguish between a device which isn't actually device, and a device that is (perhaps an 'instance'?) It seems better to rename this macro to describe what it actually is. The macros is not widely used, since boards should use devicetree to declare devices. Rename it to U_BOOT_DRVINFO(), which indicates clearly that this is declaring a new driver_info record, not a device. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: treewide: Rename 'platdata' variables to just 'plat'Simon Glass2020-12-131-1/+1
| | | | | | | | | | We use 'priv' for private data but often use 'platdata' for platform data. We can't really use 'pdata' since that is ambiguous (it could mean private or platform data). Rename some of the latter variables to end with 'plat' for consistency. Signed-off-by: Simon Glass <sjg@chromium.org>
* mx6: peripheral clock from oscillatorJorge Ramirez-Ortiz2020-11-011-1/+4
| | | | | | | | | | | | | | | | In order to be able to run the I2C bus at 400Khz, the chip errata[1] recommends that the peripheral clock runs out of the 24MHz oscillator. Systems running I2C from OP-TEE before Linux executes - for example to access a Secure Element [2] providing the cryptographic support - expect this clock to be configured by the bootloader [3]. [1] IMX6SLCE Rev. 5, 02/2019, ERR007805. [2] OP-TEE: support for NXP SE05X Plug and Trust (patch on the list). [3] OP-TEE: check the imx_i2c.c driver (imx6 patch on the list).

* imx: mx6cuboxi: Disable thermal driver in SPLSimon Glass2020-10-291-1/+1
| | | | | | | | | | | This feature is incompatble with of-platdata since it uses the U_BOOT_DEVICE() macro. With of-platdata the only devices permitted are those created by dtoc. The driver is not used in SPL anyway, so exclude it from that build. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Fabio Estevam <festevam@gmail.com>

| | | | | | | | | | Even if the HAB fuse is not set we want to be able to use the Cryptographic Accelerator and Assurance Module (CAAM) for generating random numbers. So SYS_FSL_HAS_SEC should be selected even if IMX_HAB is not set. arch_misc_init() has to be called to initialize the CAAM. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-071-2/+1
| | | | | | | | | | | | | | | | | | | | 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>
