2018-12-26arm: K3: Fix usage of CONFIG_SYS_K3_KEYLokesh Vutla
For signing the tiboot3.bin image, an optional KEY file can be passed using CONFIG_SYS_K3_KEY. Right now, Makefile scripts directly takes the config value and uses it for signing. This is okay if the build directory is a sub-directory of source tree, otherwise it fails. Fix it by using the path relative to the source tree.

2018-11-26armv7r: K3: Allow SPL to run only on core 0Lokesh Vutla
Based on the MCU R5 efuse settings, R5F cores in MCU domain either work in split mode or in lock step mode. If efuse settings are in lockstep mode: ROM release R5 cores and SPL continues to run on the R5 core is lockstep mode. If efuse settings are in split mode: ROM releases both the R5 cores simultaneously and allow SPL to run on both the cores. In this case it is bootloader's responsibility to detect core 1 and park it. Else both the core will be running bootloader independently which might result in an unexpected behaviour. Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com>

2018-11-16ram: Introduce K3 AM654 DDR Sub System driverLokesh Vutla
K3 based AM654 devices has DDR memory subsystem that comprises Synopys DDR controller, Synopsis DDR phy and wrapper logic to intergrate these blocks into the device. This DDR subsystem provides an interface to external SDRAM devices. Adding support for the initialization of the external SDRAM devices by configuring the DDRSS registers and using the buitin PHY routines.

2018-10-10arm: K3: am654: Add support for getting boot modeAndrew F. Davis
Read the boot mode register to find the boot mode. Only use eMMC boot0 mode when the mode is eMMC boot (called BOOT_DEVICE_MMC1 currently due to current conflating of boot mode and boot device), and not iff the boot device is MMC port 0.

2018-10-10arm: K3: am654: Choose MMC boot device based on boot portAndrew F. Davis
For most devices the boot mode maps directly to the boot device. For MMC this is not the case as we have two MMC boot modes and two MMC boot devices (ports). Check the boot port to determine which MMC device was our boot device. Make this change for both primary and secondary boot modes. Signed-off-by: Andrew F.

AM654 allows for booting from primary or backup boot media. Both media can be chosen individually based on switch settings. ROM looks for a valid image in primary boot media, if not found then looks in backup boot media. In order to pass this boot media information to boot loader, ROM stores a value at a particular address. Add support for reading this information and determining the boot media correctly.
