* ARM: dts: bcm2835-rpi: re-enable booting from SD cardRoland Hieber2017-12-071-0/+8
| | | | | | | | | | | | | | | | | | | | | | | Kernel commit a19adf8d86e822eba502486524127595372c85f6 [0] changed the RPi1 device tree from &sdhci to &sdhost, which was imported in barebox commit d14b844b08635c717fb52a294ed8d6872e260315. It seems that barebox does not have a driver for brcm,bcm2835-sdhost (yet), which resulted in barebox unable to boot from SD card. However, the driver for brcm,bcm2835-sdhci worked fine in the past. Although the upstream change was made for good reasons, the simplest change for barebox for now is to revert to using &sdhci and disable &sdhost. Thanks to Alexander Dahl for raising this issue on the DistroKit mailing list!

* ARM: boards: phytec-som-am335x: Fix SPI boot scriptDaniel Schultz2017-11-211-1/+1
| | | | | | | | | | | | Because our SPI NOR flashes are too small, we require a root filesystem in a NAND media. The kernel bootargs has a wrong parameter and lead to: VFS: Cannot open root device "ubi0:root" or unknown-block(0,0): Changed 'ubi.mtd=nand0.root' to 'ubi.mtd=root'.

| * ARM: boards: phytec-som-am335x: Add unified MLODaniel Schultz2017-11-071-18/+132
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PCM-060 modules only have one-bank RAMs populated, which allows us to find out the populated RAM size at run-time. Therefore, a new entry point was create 'PHYTEC_ENTRY_UNIFIED_MLO'. This creates a MLO for all modules of one family and all existing PCM-060 MLOs were replaced with this new entry point. To provide backward compatibility for older modules, these were not affected. In the first step generic RAM timings for the module family get loaded, because RAM accesses are only possible with an initialized controller. After that, the RAM size will be calculated and the RAM controller gets reinitialized with the correct RAM timings.

| * | usb: imx: implement support for "over-current-active-high" propertyUwe Kleine-König2017-10-271-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This property is already documented in the bindings and supported by Linux. As on i.MX25 the HW default is active high and up to now barebox didn't force this to low (which is the default for e.g. i.MX6), add the property to barebox' imx25.dtsi to keep existing behaviour. If on a board the OC pin is active low, you need to add /delete-property/ over-current-active-high; in the board.dts.

| | | | | | | | | | | If the zImage has a padding, which is less than 40 bytes (sizeof struct fdt_header) the amount of read bytes would be propagated as an error code. Fix this by only propagating real errors and treating failure to read less than the expected amount as no concatenated DT being present.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On i.MX6ul(l) (Cortex A7) We have to set the SMP bit before enabling the caches, otherwise they won't work. Add a SoC specific lowlevel_init function to be called by the i.MX6ul(l) boards. Since this is a quirk of the Cortex A7 core we put the functionality into a separate function to be reused by other Cortex A7 cores. Change existing i.MX6ul(l) boards to use the new initialisation function. It seems this is only needed when booting from USB, in other boot modes the ROM will already have done the initialisation.
