2020-08-03	f9e7a60 Browse files » gpio: get function returns masked register value ... Unlike Linux the generic driver get function returns the masked register content and not the 0 or 1 value. The consequence is that gpio_get_value returns for instance 0x10 for bit 4 instead of 1. Use the Linux normalized form instead.

2020-08-03	c667f8c Browse files » i2c: stm32: support new st,stm32mp15-i2c compatible ... Linux v5.8-rc1 has gained support for the FastMode+ registers on the stm32mp15, but those are incompatible between the stm32mp15 and the stm32f7, so a new compatible was introduced. The old compatible was replaced for the MP15 SoC, breaking I2C in barebox. Add the new compatible to fix this. Unlike Linux, we just use the same setup parameters as for the stm32f7. This is ok as long we don't want to support FastMode+.

	d46b337 Browse files » mci: imx-esdhc-pbl: Add imx8mp_esdhc_load_image() for i.MX8MP ... The image format of the i.MX8MP is different from i.MX8M, so add its own image loading function for it. Older i.MX SoCs had a IVT Offset (the offset from the start of the image to the actual data) of 1KiB. This was done to leave space for the partition table at the beginning of the device. To support GPT SoCs starting with i.MX8M an additional gap of 32KiB was added, so that the actual image started at offset 33KiB. Now starting with i.MX8MP the now superfluous 1KiB offset was removed do that the actual image now starts at 32KiB. Unfortunately the 1KiB offset is woven into the offsets of the IVT whereas the 32KiB are not, which means that we really have to handle both offsets individually instead of just handling the sum of the offsets.

According to data sheet the mode register containing the timeout can be configured only once, but I couldn't verify this on the sama5d2. Regardless, the driver takes care not to change the mode register unless necessary. Implementation that want to leave to the OS the decision which timeout to choose, can just keep pinging with the POR-default of 16 seconds and the OS will be able to set the final timeout.
