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.

2016-10-07ARM: vf610: use strcpy for soc environment variableStefan Agner
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.

2016-10-06ARM: OMAP5+: Override switch_to_hypervisor functionKeerthy
Override the switch_to_hypervisor function to switch cpu to hypervisor mode using the available ROM code hook early in the boot phase before the boot loader checks for HYP mode.

2016-10-06ARM: Introduce function to switch to hypervisor modeKeerthy
On some of the SoCs one cannot enable hypervisor mode directly from the u-boot because the ROM code puts the chip to supervisor mode after it jumps to boot loader. Hence introduce a weak function which can be overridden based on the SoC type and switch to hypervisor mode in a custom way.

2016-10-06ARM: Respect CONFIG_SPL_STACK define in lowlevel_init.SSiarhei Siamashka
The SPL and U-Boot proper may use different initial stack locations, which are configured via CONFIG_SPL_STACK and CONFIG_SYS_INIT_SP_ADDR defines. The lowlevel_init.S code needs to handle this in the same way as crt0.S Without this fix, setting the U-Boot stack location to some place, which is not safely accessible by the SPL (such as the DRAM), causes a very early SPL deadlock.

2016-10-06armv8/fsl-lsch2: Implement workaround for PIN MUX erratum A010539Hou Zhiqiang
Pin mux logic has 2 options in priority order, one is through RCW_SRC and then through RCW_Fields. In case of QSPI booting, RCW_SRC logic takes the priority for SPI pads and do not allow RCW_BASE and SPI_EXT to control the SPI muxing. But actually those are DSPI controller's pads instead of QSPI controller's, so this workaround allows RCW fields SPI_BASE and SPI_EXT to control relevant pads muxing.
