[U-Boot] [PATCH v3 0/9] pico-imx7d: Add support for BL33 case

[U-Boot] [PATCH v3 0/9] pico-imx7d: Add support for BL33 case

[Jun Nie]

Add configuration to boot U-boot as BL33 case. The boot flow
is ATF -> OPTEE -> U-boot.

Changes vs V2:
- Revise fix to UART clock ID.
- Add documentation of build and test for BL33 usage case.
- Add device tree to store public key for FIT image verfication usage.
- Add revert patch to LCD support. Pico-pi does not boot with it.
    I see it is suggested to be reverted in maillist.

Changes vs V1:
- Remove DCD file.
- Add a patch to fix uart clock root ID.
- Change file name from pico-pi-imx7d_bl33_defconfig to pico-imx7d_bl33_defconfig

It blocks boot up with default defconfig. I see it is suggested to be
reverted in mailist weeks ago. I thought you guys knew about it.

Hi Jun,

Please keep in mind that the rationale of a patch must always be provided.

In this case the issue is related to the limit of the current that the
host PC USB port can provide.

Please see the following commit for detaisl:

commit 00102ae52055e294ac37ae1380f37620f4a8bb26

    pico-imx7d: README: Recommend the usage of a USB hub

    Since commit 9e3c0174da842 ("pico-imx7d: Add LCD support") we started to
    notice some hangs in U-Boot.

    There is not an issue on such commit per se, but due to the LCD support
    the current drawn is increased and this may cause issues when powering
    pico-imx7d-pi from USB.

    Some computers may be a bit strict with USB current draw and will
    shut down their ports if the draw is too high.

    The solution for that is to use an externally powered USB hub between the
    board and the host computer.

    Add such recommendation to the README file.

Thank you very much for this info! I did not noticed this patch yet.
So power supply should be changed or disable LCD as a workaround
locally.

This drops a feature developped from someone else without any
clarification. I won't apply this.

[U-Boot] [PATCH v3 2/9] mx7_common: Share configs to skip low level init

[Jun Nie]

Share configs in mx7 to skip low level init if we are in the case where
OPTEE is loaded already (maybe by ARM Trusted Firmware) and that most of
the low level initialization is already done and that we may/should skip
it doing them here.

Fix the definition detection with size detection to decide whether to skip
it.

[U-Boot] [PATCH v3 3/9] imx: mx7: Add empty arch_cpu_init if skipped

[Jun Nie]

Add empty arch_cpu_init if low level init is skipped. So that
it does not break spl compile though spl is not needed in the
skipped case actually.

Please describe what ATF/OP-TEE initialization has done
when booting into uboot.

I think SKIP_LOWLEVEL_INIT is mostly for lowlevel_init,
not arch_cpu_init.

init_aips/init_csu/isolate_resources/init_snvs might be
done in your ATF, I am not sure, but imx_enet_mdio_fixup,
mxs_dma_init, imx_gpcv2_init, are these also done in ATF?

Regards,
Peng.

Yes, aips/csu/snvs/caam/watchdog are initialized.  Other missing stuff does
not introduce issue in my case so I just added back the empty function to
pass build. Will add them back for safe in next version. Thanks for the
reminder.

Yes. hardcoding to UART1_ROOT_CLK in imx_get_uartclk is not good.
But actually init_clk_uart configures all the uart with same root clk,
so it should work as expected.

Peng.

Right, but init_clk_uart is not called in SKIP_LOWLEVEL_INIT case.
#ifndef CONFIG_SKIP_LOWLEVEL_INIT
cpu_init_crit() ->  lowlevel_init() -> s_init() -> clock_init() ->
init_clk_uart()

Supposed so.

[U-Boot] [PATCH v3 5/9] pico-imx7d: Reserve region of memory to OPTEE

[Jun Nie]

Subtracts CONFIG_OPTEE_TZDRAM_SIZE from the available DRAM size so that
the OPTEE memory is not override during u-boot relocation.

Note the OPTEE boot process will itself subtract the DRAM region it lives
in from the memory map passed to Linux.

There is a series from Joris that does the pico-mx7d DM conversion.

When is that series expected to be merged?

Great! I will prepare my patch based on that. But I cannot find latest
pico patch on denx master repo. Did you merge it to your own repo and
pulled to denx master later, just like linux work flow? I am not
familiar with u-boot work flow yet. Thanks for point the repo in
advance!

Right.

Yes.

Because PR are rejected if not verified by Travis, I push first to
https://github.com/sbabic/u-boot-imx (-next branch). If report from
Travis is ok (this is needed in PR), I push to git.denx.de/u-boot-imx
(-master).

Stefano

+This document describes the instruction to build and flash ATF/OPTEE/U-Boot on
+pico-imx7d board. U-Boot is loaded as part of FIP image by ATF in this setup.
+The boot sequence is ATF -> OPTEE -> U-Boot -> Linux. U-Boot is in non-secure
+world in this case.
+
+- Build u-boot
+    Set environment variable of CROSS_COMPILE for your toolchain and ARCH=arm
+    $ make pico-imx7d_bl33_defconfig
+    $ make all
+
+- Download and build OPTEE
+    $ git clone git at github.com:OP-TEE/optee_os.git
+    $ make PLATFORM=imx PLATFORM_FLAVOR=mx7dpico_mbl CFG_BOOT_SECONDARY_REQUEST=y ARCH=arm
+
+- Download and build ATF
+    $ git clone https://git.linaro.org/landing-teams/working/mbl/arm-trusted-firmware.git -b linaro-imx7
+    $ make DEBUG=1 PLAT=picopi ARCH=aarch32 ARM_ARCH_MAJOR=7 \
+            CROSS_COMPILE=arm-linux-gnueabihf- LOG_LEVEL=50 V=1 \
+            CRASH_REPORTING=1 AARCH32_SP=optee all
+    Save file content in this link to file pico-imx7d.cfg:
+      http://git.linaro.org/landing-teams/working/mbl/u-boot.git/tree/board/technexion/pico-imx7d/pico-imx7d.cfg?h=linaro-imx
+    $ u-boot/tools/mkimage -n pico-imx7d.cfg -T imximage -e 0x9df00000 -d \
+            build/picopi/debug/bl2.bin bl2.imx
+
+- Create FIP image
+    Create a  fiptool_images/ folder in ATF folder, copy u-boot.bin in u-boot
+folder and tee*.bin in optee out/arm-plat-imx/core/tee/ folder to
+fiptool_images. Run below command in ATF folder to generate FIP image.
+    $ make -C tools/fiptool/
+    $ tools/fiptool/fiptool create --tos-fw fiptool_images/tee-header_v2.bin \
+          --tos-fw-extra1 fiptool_images/tee-pager_v2.bin \
+          --tos-fw-extra2 fiptool_images/tee-pageable_v2.bin \
+          --nt-fw fiptool_images/u-boot.bin \
+          fip.bin
+
+- Burn the images to eMMC for test.
+    Run below command in atf folder:
+    $ dd if=build/picopi/debug/bl2.bin.imx of=/dev/disk/by-id/usb-<your device>  bs=1024 seek=1;sync
+    $ dd if=fip.bin of=/dev/disk/by-id/usb-<your device>  bs=1024 seek=1;sync
+
+- Test
+    Just boot up your board and wait for u-boot start up after ATF's log.
+    For booting Linux in FIT image, please reference the FIT files in
+    u-boot doc/uImage.FIT/ folder.
