This package add support for imx-mkimage for iMX8M.
Currently the only hardware it's tested for.
Signed-off-by: Erik Larsson <karl.erik.larsson@gmail.com>

---
v6: Moved back to version v1 where imx-mkimage only build mkimage_imx8
and copy it together with mkimage_fit_atf.sh into host binaries.
(suggested by Thomas P.)
v5: Build with HDMI support
Add patch to use host mkimage instead of ./mkimage_uboot in soc.mk
Add host dependencies to dtc package
Add host configuration options in build
Add patch to make use of LDFLAGS in soc.mk (fixes build error with libz)
v4: No changes
v3: Use BR2_TARGET_UBOOT_FORMAT_CUSTOM_NAME in U-Boot so we don't
need to copy u-boot.bin to u-boot-nodtb.bin (suggested by Baruch)
Update license to GPL-2.0+ (suggested by Marcus F.)
v2: Moved package from package/freescale-imx to package (suggested by Thomas P.)
Add upstread URL in Config.in (suggested by Thomas P.)
Fix install syntax in imx-mkimage.mk (suggested by Thomas P.)
Use Makefile in imx-mkimage to build imx-boot-imx8mqevk-sd.bin instead of doing that in the post-script.sh (suggested Baruch)

Thanks, I've applied to master, after doing a few changes. I also have
one request. See below.

You forgot to add an entry in the DEVELOPERS file for this new package,
so I've done so.

This commit log really needs to be extended. What was the need to add
LDFLAGS ? It seems like a very simple program, which could be built
without special LDFLAGS. What was the issue that lead you to add this
patch ?

We prefer a complete destination path that includes the name of the
file to install. Indeed, with the way you have written the commands, if
$(HOST_DIR)/bin doesn't exist as a directory, mkimage_imx8 will be
installed as a file called "bin" in $(HOST_DIR). I've also fixed this
when applying.
Thanks!

If LDFLAGS is not added it will use the host machine libz, and fail if
not available, but by adding LDFLAGS it will build using Buildroot
compiled libz. Do you want me to update the patch information in a new
patch?

Hum, indeed, we're building a host package here, so we need to
explicitly pass -L$(HOST_DIR)/lib, otherwise we link against the
system-provided libraries.

Yes, that would be nice. Thanks!

I'm a bit unhappy with the division of work between this .mk file and
the post-image script. Why are you doing the padding here, and then the
concatenation in the post-image script?
I think it should be done in just one place. Perhaps this package is
the most logical location. Also, use $(...) instead of ${...} in shell
to refer to variables.
So, perhaps:
define FIRMWARE_IMX_PREPARE_LPDDR4_FW
(cd $(@D)/firmware/ddr/synopsys/ && \
$(TARGET_OBJCOPY) -I binary -O binary --pad-to 0x8000 --gap-fill=0x0 \
lpddr4_pmu_train_$(1)_imem.bin \
lpddr4_pmu_train_$(1)_imem_pad.bin
$(TARGET_OBJCOPY) -I binary -O binary --pad-to 0x4000 --gap-fill=0x0 \
lpddr4_pmu_train_$(1)_dmem.bin \
lpddr4_pmu_train_$(1)_dmem_pad.bin
cat lpddr4_pmu_train_$(1)_imem_pad.bin lpddr4_pmu_train_$(1)_dmem_pad.bin > \
lpddr4_pmu_train_$(1)_fw.bin
)
endef
define FIRMWARE_IMX_INSTALL_IMAGES_CMDS
$(call FIRMWARE_IMX_PREPARE_LPDDR4_FW,1d)
$(call FIRMWARE_IMX_PREPARE_LPDDR4_FW,2d)
cat $(@D)/firmware/ddr/synopsys/lpddr4_pmu_train_1d_fw.bin \
$(@D)/firmware/ddr/synopsys/lpddr4_pmu_train_2d_fw.bin > \
$(BINARIES_DIR)/lpddr4_pmu_train_fw.bin
...
endef
And then the post-image script can use
$(BINARIES_DIR)/lpddr4_pmu_train_fw.bin.
Best regards,
Thomas

v6: Generate imx-boot-imx8mqevk-sd.bin in post-image.sh using tools built
with package imx-mkimage. (suggested by Thomas P.)
Fix minor type in readme.txt (suggested by Fabio E.)
Add BR2_TARGET_UBOOT_NEEDS_DTC to defconfig
v5: Added readme.txt in board/freescale/imx8mqevk (suggested by Fabio E.)
Change version tags to rel_imx_4.9.51_8mq_beta_patch
for kernel, u-boot and atf (suggested by Baruch S.)
Remove generation of rootfs.tar
v4: Change to Buildroot toolchain from external toolchain
v3: Change commit message (suggested by Thomas P.)
Make sure to use tags instead of branches in kernel,bootloader and ATF repositorires (Arnout V.)
Use BR2_LINUX_KERNEL_USE_ARCH_DEFAULT_CONFIG instead of copy kernel defconfig to board folder (suggested by Arnout V.)
Split v2 commit into two commits

+***************************
+Freescale i.MX8mq EVK board
+***************************
+
+This file documents the Buildroot support for the Freescale i.MX8mq EVK board.
+
+Hardware support
+================
+
+Currently only basic support for hardware is avialable, currently no
+support for GPU, VPU and other HW features.
+
+Build
+=====
+
+First, configure Buildroot for the i.MX8mq EVK board:
+
+ make freescale_imx8mqevk_defconfig
+
+Build all components:
+
+ make
+
+You will find in output/images/ the following files:
+ - bl31.bin
+ - boot.vfat
+ - fsl-imx8mq-evk.dtb
+ - Image
+ - imx-boot-imx8mqevk-sd.bin
+ - lpddr4_pmu_train_1d_dmem.bin
+ - lpddr4_pmu_train_1d_imem.bin
+ - lpddr4_pmu_train_2d_dmem.bin
+ - lpddr4_pmu_train_2d_imem.bin
+ - rootfs.ext2
+ - rootfs.ext4
+ - rootfs.tar
+ - sdcard.img
+ - signed_hdmi_imx8m.bin
+ - u-boot.bin
+ - u-boot.imx
+ - u-boot-nodtb.bin
+
+Create a bootable SD card
+=========================
+
+To determine the device associated to the SD card have a look in the
+/proc/partitions file:
+
+ cat /proc/partitions
+
+Buildroot prepares a bootable "sdcard.img" image in the output/images/
+directory, ready to be dumped on a SD card. Launch the following
+command as root:
+
+ dd if=output/images/sdcard.img of=/dev/<your-sd-device>
+
+*** WARNING! This will destroy all the card content. Use with care! ***
+
+For details about the medium image layout, see the definition in
+board/freescale/common/imx/genimage.cfg.template_imx8.
+
+Boot the i.MX8mq EVK board
+==========================
+
+To boot your newly created system:
+- insert the SD card in the SD slot of the board;
+- put a micro USB cable into the Debug USB Port and connect using a terminal
+ emulator at 115200 bps, 8n1;
+- power on the board.
+
+Enable HDMI output
+==================
+
+To enable HDMI output at boot you must provide the video kernel boot argument.
+To set the video boot argument from U-Boot run after stoping in U-Boot prompt:
+
+setenv mmcargs 'setenv bootargs console=${console} root=${mmcroot} video=HDMI-A-1:1920x1080-32 at 60'
+saveenv
+reset
+
+Change screen resolution to suit your connected display.
+
+Enjoy!

Those two changes could be in a patch reworking post-image.sh to be

Shouldn't this logic be moved to a specialized post-image script ? And
then you do:
BR2_ROOTFS_POST_IMAGE_SCRIPT="board/freescale/common/imx/imx8-bootloader-prepare.sh board/freescale/common/imx/post-image.sh"
or something like that ? Fabio, what do you think ?
Also, could you split the i.MX8 stuff from the support of the i.MX8 EVK board itself ?
I.e adding the genimage.cfg file, and adding imx8-bootloader.prepare.sh
should be one patch, and then adding the i.MX8 EVK defconfig and
readme.txt should be another patch.
Could you rework the last two patches according to those comments ?
Thanks a lot!

I've started to rework this and have something that at least works.
I've moved the generation of imx-boot-imx8mqevk-sd.bin to a separate
prepare script and tried to separate what is iMX8 general and what is
imx8mqevk specific in that script. So the gen_imx8_boot() function can
be removed from post-script.sh. I still need to keep the selection of
genimage.cfg.template in post-script.sh but instead of checking for
IMX8M it can check if it's a IMX8 platform. Is it something like that
you hade in mind?

How are you going to check if it's an IMX8 platform ? For me, the test
on BR2_PACKAGE_FREESCALE_IMX_PLATFORM_IMX8M to decide which genimage
file to use was fine. What I wanted is:
(1) Split in different commits the introduction of i.MX8 support and
the addition of the i.MX8 EVK support. A first commit should
change the post-image.sh script to add i.MX8 stuff, and separate
commit should add the defconfig and board/ stuff related to the
i.MX8 EVK board.
(2) Split the i.MX8 specific bootloader preparation logic outside of
the common post-image into a separate script called as a
post-image script.
Best regards,
Thomas

Okay, maybe I over complicated it a bit then. I used
BR2_PACKAGE_FREESCALE_IMX_PLATFORM to check if it's equal to "IMX8"
when selecting genimage file to use. But if you are okay with
BR2_PACKAGE_FREESCALE_IMX_PLATFORM_IMX8M then I think it will be much
more clearer. I'll look this over one more time.

Any comments on this? I think this serie was missed by Patchwork a
couple of weeks ago. I've also been a bit quiet due to the fact that
I'm on my honeymoon and was not allowed to bring my iMX8 board. But
I'm back on track in a couple of days.
