As of today __dc_line_op() and __dc_entire_op() support
only separate flush (OP_FLUSH) and invalidate (OP_INV) operations.
Add support of combined flush and invalidate (OP_FLUSH_N_INV)

__cache_line_loop() function was copied from Linux kernel
where per-line instruction cache operations are really used.
In U-Boot we use only entire I$ ops, so we can drop support of
per-line I$ ops from __cache_line_loop() because __cache_line_loop()
is never called with OP_INV_IC parameter.

We improve on 2 things:
1. Only ARC HS family has "dmb" instructions so do compile-time
check for automatically defined macro __ARCHS__.
Previous check for ARCv2 ISA was not good enough because ARC EM
family is v2 ISA as well but still "dmb" instaruction is not
supported in EM family.
2. Still if there's no dedicated instruction for memory barrier
let's at least insert compile-time barrier to make sure
compiler deosn't reorder critical memory operations.

Disabling relocation might be useful on ARC for 2 reasons:
a) For advanced debugging with Synopsys proprietary MetaWare debugger
which is capable of accessing much more specific hardware resources
compared to gdb. For example it may show contents of L1 and L2 caches,
internal states of some hardware blocks etc.
But on the downside MetaWare debugger still cannot work with PIE.
Even though that limitation could be work-arounded with change of ELF's
header and stripping down all debug info but with it we won't have
debug info for source-level debugging which is quite inconvenient.
b) Some platforms which might benefit from usage of U-Boot basically
don't have enough RAM to accommodate relocation of U-Boot so we
keep code in flash and use as much of RAM as possible for more
interesting things.

This commit basically reverts two commits:
1. cf628f772e ("arc: arcv1: Disable master/slave check")
2. 6cba327bd9 ("arcv2: Halt non-master cores")
With mentioned commits in-place we experience more trouble than
benefits. In case of SMP Linux kernel this is really required as
we have all the cores running from the very beginning and then we
need to allow master core to do some preparatory work while slaves
are not getting in the way.
In case of U-Boot we:
a) Don't really run more than 1 core in parallel
b) We may use whatever core for that

U-Boot is a bit special piese of software because it is being
only executed once on power-on as compared to operating system
for example. That's why we don't care much about performance
optimizations instead we're more concerned about size. And up-to-date
compilers might produce much smaller code compared to
performance-optimized routines copy-pasted from the Linux kernel.
Here's an example:
------------------------------->8--------------------------
--- size_asm_strings.txt
+++ size_c_strings.txt
@@ -1,2 +1,2 @@
text data bss dec hex filename
- 121260 3784 3308 128352 1f560 u-boot
+ 120448 3784 3308 127540 1f234 u-boot
------------------------------->8--------------------------
See we were able to shave off ~800 bytes of .text section.
Also usage of string routines implemented in C gives us an ability
to support more HW flavors for free: generated instructions will match
our target as long as correct compiler option is used.

This patch adds a new type IH_OS_TEE. This new OS type will be used for
chain-loading to Linux via a TEE.
With this patch in-place you can generate a bootable OPTEE image like this:
mkimage -A arm -T kernel -O tee -C none -d tee.bin uTee.optee
where "tee.bin" is the input binary prefixed with an OPTEE header and
uTee.optee is the output prefixed with a u-boot wrapper header.
This image type "-T kernel -O tee" is differentiated from the existing
IH_TYPE_TEE "-T tee" in that the IH_TYPE is installed by u-boot (flow
control returns to u-boot) whereas for the new IH_OS_TEE control passes to
the OPTEE firmware and the firmware chainloads onto Linux.
Andrew Davis gave the following ASCII diagram:

CONFIG_OPTEE_LOAD_ADDR is used to tell u-boot where to load the OPTEE
binary into memory prior to handing off control to OPTEE.
We need to pull this value out of u-boot in order to produce an IMX IVT/CSF

have CONFIG_OPTEE_LOAD_ADDR appear in u-boot.cfg.
