2016-10-30sunxi: Add support for SID e-fuses on sun9iChen-Yu Tsai
The A80 has SID e-fuses. Like other newer SoCs, the actual e-fuses are at an offset of 0x200 within the SID address space. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Acked-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com>

2016-10-30sunxi: Enable SMP mode for the boot CPU on sun9i (A80)Philipp Tomsich
Since the A80 has many cores which we intend to use in SMP fashion, we should set the SMP bit for the boot CPU. [wens@csie.org: Added commit message] Signed-off-by: Chen-Yu Tsai <wens@csie.org> Acked-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com>
2016-10-30sunxi: add gtbus-initialisation for sun9iPhilipp Tomsich
On sun9i, the GTBUS manages transaction priority and bandwidth for multiple read ports when accessing DRAM. The initialisation mirrors the settings from Allwinner's boot0 for now, even though this may not be optimal for all applications (e.g. headless systems might want to give priority to IO modules). Adding a common callout to gtbus_init() from the SPL clock init with a weakly defined implementation in sunxi/clock.c to fallback to for platforms that don't require this.

2016-10-30sunxi: DRAM initialisation for sun9iPhilipp Tomsich
This adds DRAM initialisation code for sun9i, which calculates the appropriate timings based on timing information for the supplied DDR3 bin and the clock speeds used. With this DRAM setup, we have verified DDR3 clocks of up to 792MHz (i.e. DDR3-1600) on the A80-Q7 using a dual-channel configuration.

Mostly by adding MACH_SUN50I to some existing #ifdefs enable support for the the HCI0 USB host controller on the A64. Fix up some minor 64-bit hiccups on the way. Add the bare minimum DT bits to the A64 .dtsi and enable the controllers and the PHY on the Pine64. This is limited to the first USB controller at the moment, which is connected to the lower USB socket on the Pine64 board.

2016-10-10ARM: tegra: reduce DRAM size mapped into MMU on ARM64Stephen Warren
ARM CPUs can architecturally (speculatively) prefetch completely arbitrary normal memory locations, as defined by the current translation tables. The current MMU configuration for 64-bit Tegras maps an extremely large range of addresses as DRAM, well beyond the actual physical maximum DRAM window, even though U-Boot only needs access to the first 2GB of DRAM; the Tegra port of U-Boot deliberately limits itself to 2GB of RAM since some HW modules on at least some 64-bit Tegra SoCs can only access a 32-bit physical address space. This change reduces the amount of RAM mapped via the MMU to disallow the CPU from ever speculatively accessing RAM that U-Boot will definitely not access. This avoids the possibility of the HW raising SError due to accesses to always-invalid physical addresses.
