According current code base, CONFIG_LS1012A should be

wrongly called to disable all dwc3 USB nodes on LS1012A, which
cause Linux USB function stop working at all.

a797f274d7 ARMv8/sec_firmware : Update chosen/kaslr-seed with random number
kASLR support in kernel requires a random number to be passed via
chosen/kaslr-seed propert. sec_firmware generates this random seed
which can then be passed in the device tree node.

sec_firmware reserves JR3 for it's own usage. Node for JR3 is
removed from device-tree.

fa18ed7658 armv8/ls1043a: fixup GIC offset for ls1043a rev1
The LS1043A rev1.1 silicon supports two types of GIC offset: 4K
alignment and 64K alignment. The bit SCFG_GIC400_ALIGN[GIC_ADDR_BIT]
is used to choose which offset will be used.

The LS1043A rev1.0 silicon only supports the CIG offset with 4K
alignment.

If GIC_ADDR_BIT bit is set, 4K alignment is used, or else 64K alignment
is used. 64K alignment is the default setting.

Overriding the weak smp_kick_all_cpus, the new impletment is able to
detect GIC offset.

The default GIC offset in kernel device tree is using 4K alignment, it
need to be fixed if 64K alignment is detected.

NXP/Freescale uses macro CONFIG_ARMV8_PSCI to enable their private PSCI
implementation in PPA firmware, but this macro naming too generic, so this
patch replaces it with a specic one CONFIG_FSL_PPA_ARMV8_PSCI.
And this macro CONFIG_ARMV8_PSCI will be used for a generic PSCI for ARMv8
which will be added in following patchs.
