2018-09-20mx6: ddr: allow 32 cycles for DQS gating calibrationEric Nelson
The DDR calibration code is only setting flag DG_CMP_CYC (DQS gating sample cycle) for the first PHY. Set the 32-cycle flag for both PHYs and clear when done so the MPDGCTRL0 output value isn't polluted with calibration artifacts.

2018-09-20colibri_imx6: apply nreset_out only if no power-onStefan Bigler
Fix the nreset_out() and only pull-down nRESET_OUT reset case was not a power-on reset. Cannot use get_imx_reset_cause() because static variable reset_cause is not initialized, normal done by get_reset_cause() much later.

2018-09-13imx: imx-common: do not zero out outside of regionsStefan Agner
There are two issues with the zeroing out code currently: The cache flush does not take the zeroed out section into account! The M4 firmware is started right after copying the firmware, and might use the memory area. Since the M4 and the A7 (where U-Boot is running) are not cache coherent, flushing cache could overwrite the M4's variable at any point in time, leading to crashes of the M4 firmware... Secondly, the program header of a Cortex-M4 firmware might look like this: LOAD off 0x00007240 vaddr 0x20000240 paddr 0x1fffdcdc align 2**12 filesz 0x000001d0 memsz 0x000055c4 flags rw- The code uses paddr as base, and zeros out everything which is beyond file size. This might overlap into the next section! It seems that memsz is in vaddr space and not paddr... Since zeroing out is not strictly necessary (the firmwares C initialization code should do that anyway) better play safe and don't initialize the empty bytes...

2018-09-13colibri_vf: Fix sdboot in vf modulesGerard Salvatella
Currently Vybrids sdboot variable tries to load the kernel from /boot of the root partition (typically second partition when using the sdcard image). However, since we moved to flash the kernel in a separate UBI volume, we no longer deploy the kernel/device tree to /boot, hence sdboot does not work in its current state. Load the kernel and device tree from the first (typically FAT) partition as customary on all Toradex modules.

2018-09-13board: toradex: turn off lcd backlight before OS handoverGerard Salvatella
U-Boot typically tears down the display controller before handing control over to Linux. On LCD displays disabling pixel clock leads to a fading out effect with vertical/horizontal lines.

2018-09-13common: add board specific hook for os pre-boot configGerard Salvatella
Some boards require specific configuration prior to booting the kernel. For instance, our boards require shutting down the display to avoid fading transitions before the drivers are reloaded by the kernel.

2018-07-27apalis/colibri_imx6/imx6ull: make sure loadaddr does not collideStefan Agner
Currently $loadaddr and $fdt_addr_r point to the same address. This might be not ideal for some distro boot scripts which make use of $loadaddr after loading the device tree. Make sure the two variables point to two different addresses. Moving $loadaddr is not entirly trivial since it is defined in mx6_common.h. Move $fdt_addr_r and $ramdisk_addr_r by 1MiB, which should be enough for scripts. Signed-off-by: Stefan Agner <stefan.agner@toradex.com> Acked-by: Marcel Ziswiler <marcel.ziswiler@toradex.com>
