2016-10-14ARM: create .secure_stack section only for PSCIMasahiro Yamada
Jon Master reports that QEMU refuses to load a U-Boot image built with CONFIG_ARMV7_NONSEC, but without CONFIG_ARMV7_PSCI since commit 5a3aae68c74e ("ARM: armv7: guard memory reserve for PSCI with #ifdef CONFIG_ARMV7_PSCI"). It looks like only PSCI that needs the Secure stack, so move the #ifdef to guard the whole of .secure_stack allocation in order not to create the empty section.

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.

2016-10-10sunxi: Fix H3 DRAM impedance calibration on rev. A chipsJens Kuske
H3 seems to have a silicon bug breaking the impedance calibration. This is currently worked around in software by multiple steps combining the results to replace the wrong values. Revision A chips need a different workaround, which is present in the vendor bootloader too, but got overlooked in lack of information and affected boards till now. This commit adds a simplified version without correction factor, which would be 1.00 for all known boards anyway.

To create the soc environment variable we concatenate two strings on the stack. So far, strcat has been used for the first string as well as for the second string. Since the variable on the stack is not initialized, the first strcat may not start using the first entry in the character array. This then could lead to an buffer overflow on the stack.
