e6149576e8 arm64: gic: Do gicv3 secure initialization based on EL level
Do gic cpu initialization based on EL level which u-boot enters.
U-Boot can't access EL3 regs when runs in EL2/EL1, etc.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

b1964c72bd armv8/gic: Fix GIC v2 initialization
Initialize all GICD_IGROUPRn registers and set up GICC_CTLR to enable
interrupts to the primary CPU. This fixes issues seen after booting a
Linux kernel from U-Boot.

40f8dec54d armv8/fsl-lsch3: Release secondary cores from boot hold off with Boot Page
Secondary cores need to be released from holdoff by boot release
registers. With GPP bootrom, they can boot from main memory
directly. Individual spin table is used for each core. Spin table
and the boot page is reserved in device tree so OS won't overwrite.

c71645ad2b arm64 patch: gicv3 support
This patch add gicv3 support to uboot armv8 platform.

Changes for v2:
  - rename arm/cpu/armv8/gic.S with arm/lib/gic_64.S
  - move smp_kick_all_cpus() from gic.S to start.S, it would be
    implementation dependent.
  - Each core initialize it's own ReDistributor instead of master
    initializeing all ReDistributors. This is advised by arnab.basu
    <arnab.basu@freescale.com>.
