cedd48e2cd cmd: fpga: Add support to load secure bitstreams
This patch adds support to load secure bitstreams(authenticated or
encrypted or both). As of now, this feature is added and tested only
for xilinx bitstreams and the secure bitstream was generated using
xilinx bootgen tool, but the command is defined in more generic way.

Command example to load authenticated and device key
encrypted bitstream is as follows
"fpga loads 0 100000 2000000 0 1"

c90c43cda8 Merge tag 'arc-updates-for-2018.07-rc1' of git://git.denx.de/u-boot-arc
Here we do a couple of minor fixes like:
 - Move .ivt section to the very beginning of the image
   by default which allows us to use that image put right
   at reset vector (usually 0x0)

 - Improve relocation fix-up which became required once
   we moved .ivt and understood a problem with existing implementation
   where we relied on a particular placement of sections.
   Now we don't care about placement because we just explicitly
   check for .text and in case of ARCompact .ivt sections

 - Re-implemnt do_reset() such that it calls reset_cpu() which
   could implmented for a particular board

And hte most important part we introduce support for yet another
devboard from Synopsys - EMDK.

2c3f9261c8 ARC: Add support for EM Development Kit board
Synopsys DesignWare ARC EM Development Kit (ARC EMDK) is
an FPGA-based development platform from Synopsys aimed to speed-up
development of software for ARC EM cores and entire subsystems based on
ARC EM like Data Fusion, Secure and Sensor & Control subsystems.

U-Boot is supposed to be used as a primary bootloader on EMDK allowing
users to easily load and start their application from micro-SD card.

ce3071287e ARC: Improve relocation fix-ups
We used to have the one and only linker script for all ARC boards
and so we relied on a particular order of symbols there.

Because of that we used __ivt_end as the marker of the end of all the
code which won't be true any longer if we move .ivt section to any other
place. That said we'd better check for each section separately.

A couple of other improvements:
 1. There's no point to include the marker of section end in interested
    range because its address is beyond the section, i.e. we should
    compare with "<" but not "<=".

 2. .ivt section for ARCv2 cores is just an array of 32-bit ints and
    they are not swapped even on little-endia cores while in case of
    ARCompact cores .ivt contains valid code so swapping is required.

 3. Just in case add check for ARC600 which is also ARCompact
    and its .ivt is normal code.

7530bb2175 ARC: Make sure .ivt section is not purged by garbage collector
Fixes commit fac4790491 ("arc: Eliminate unused code and data with GCC's garbage collector"),
see [1].

Since in case of ARCv2 .ivt only contains addrresses of
interrupt/exception handlers linker doesn't understand that this section
actually make a lot of sense and decides to get rid of it if we use
"--gc-sections".

And KEEP does exactly this, see [2].

d0a5023a35 ARC: Cache: Don't compare I$ and D$ line lengths
We don't care much about I$ line length really as there're
no per-line ops on I$ instead we only do full invalidation of it
on occasion of relocation and right before jumping to the OS.

Also as compared to Linux kernel where we don't support different
lengths of I$ and D$ lines in U-Boot we have to deal with such an
exotic configs if the target board is not supposed to run Linux kernel.

507cef3d15 test: dm: Fix wrong aliases property names
After importing v4.17-rc1 Linux commit 9130ba884640 ("scripts/dtc:
Update to upstream version v1.4.6-9-gaadd0b65c987"), sandbox build
reports below warnings:

arch/sandbox/dts/test.dtb: Warning (alias_paths): /aliases: aliases property name must include only lowercase and '-'
arch/sandbox/dts/test.dtb: Warning (alias_paths): /aliases: aliases property name must include only lowercase and '-'
arch/sandbox/dts/test.dtb: Warning (alias_paths): /aliases: aliases property name must include only lowercase and '-'
arch/sandbox/dts/test.dtb: Warning (alias_paths): /aliases: aliases property name must include only lowercase and '-'

Silent them by applying the 's/_/-/' substitution in the names of the
'fdt_dummy0', 'fdt_dummy1', 'fdt_dummy2', 'fdt_dummy3' properties.

Similar DTC warnings have been recently fixed in Linux kernel, e.g. via
v4.17-rc1 commit d366c30d19f4 ("ARM: dts: STi: Fix aliases property name
for STi boards").

If done alone, the DTS update generates a failure of the
`ut dm fdt_translation` unit test in sandbox environment as seen below:

$ ./u-boot -d arch/sandbox/dts/test.dtb
---<-snip->---
=> ut dm fdt_translation
Test: dm_test_fdt_translation: test-fdt.c
test/dm/test-fdt.c:444, dm_test_fdt_translation(): 0 == uclass_find_device_by_seq(UCLASS_TEST_DUMMY, 0, 1, &dev): Expected 0, got -19
Test: dm_test_fdt_translation: test-fdt.c (flat tree)
test/dm/test-fdt.c:444, dm_test_fdt_translation(): 0 == uclass_find_device_by_seq(UCLASS_TEST_DUMMY, 0, 1, &dev): Expected 0, got -19
Failures: 2
---<-snip->---

Fix this issue in place, by updating the "name" string in the
UCLASS_DRIVER(fdt_dummy) definition, so that it matches the newly
updated aliases properties. After that, the test passes:

$ ./u-boot -d arch/sandbox/dts/test.dtb
---<-snip->---
=> ut dm fdt_translation
Test: dm_test_fdt_translation: test-fdt.c
Test: dm_test_fdt_translation: test-fdt.c (flat tree)

82bca3625c scripts/dtc: Re-sync with Linux 4.17-rc4
To achieve a DTC state (more or less) equivalent to Linux 4.17-rc4,
backport the DTC-specific part from below Linux commits:

b23d1a241f4eb4 ("kbuild: add %.lex.c and %.tab.[ch] to 'targets' automatically")

b24413180f5600 ("License cleanup: add SPDX GPL-2.0 license identifier to files with no license")

With this commit, the diff between Linux and U-boot common DTC files is:
$ git diff --stat --diff-filter=M v4.17-rc4 <this-commit> -- scripts/dtc
  scripts/dtc/.gitignore | 2 +-
