2018-01-10drivers/misc: Share qbman init between archsAhmed Mansour
This patch adds changes necessary to move functionality present in PowerPC folders with ARM architectures that have DPAA1 QBMan hardware - Create new board/freescale/common/fsl_portals.c to house shared device tree fixups for DPAA1 devices with ARM and PowerPC cores - Add new header file to top includes directory to allow files in both architectures to grab the function prototypes - Port inhibit_portals() from PowerPC to ARM. This function is used in setup to disable interrupts on all QMan and BMan portals. It is needed because the interrupts are enabled by default for all portals including unused/uninitialised portals. When the kernel attempts to go to deep sleep the unused portals prevent it from doing so Signed-off-by: Ahmed Mansour <ahmed.mansour@nxp.com> Reviewed-by: York Sun <york.sun@nxp.com>

According current code base, CONFIG_LS1012A should be CONFIG_ARCH_LS1012A, or function fsl_fdt_disable(blob) will be wrongly called to disable all dwc3 USB nodes on LS1012A, which cause Linux USB function stop working at all.

2017-08-26ARMv8/sec_firmware : Update chosen/kaslr-seed with random numberRuchika Gupta
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. Signed-off-by: Ruchika Gupta <ruchika.gupta@nxp.com>

2017-01-18armv8/ls1043a: fixup GIC offset for ls1043a rev1Wenbin Song
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.
