[U-Boot] [PATCH v2 0/3] Enable usage of SDP for i.MX6 Sabre Auto Boards

[U-Boot] [PATCH v2 0/3] Enable usage of SDP for i.MX6 Sabre Auto Boards

[Sjoerd Simons]

Being able to upload u-boot over USB is rather useful, so ideally this
functionality should be enabled by the default config for these boards.
Currently however no USB support is built into the SPL nor is SDP
enabled for i.MX6 Sabre Auto boards.

This round only has the patches needed for SDP support, the somewhat unrelated
fixes have been been sent seperately (but without the u-boot image will
fail to boot). And ofcourse fixes the build problem reported by Fabio.

The first patch drops SPL DM support as there is no way to fit that
*and* USB support in at the momenT.

The seconds patch enabled USB & SPL SDP support for the board.

Patch three adds support for loading FIT images over SDP as that is what
is in use for the Sabre auto's main u-boot image.

Patchset tested by using uuu with the following configuration:
```
uuu_version 1.2
SDP: boot -f  SPL
SDPU: write -f u-boot-dtb.img -addr 0x10000000
SDPU: jump -addr 0x10000000
SDPU: done
```

Changes in v2:
- Fix build with CMD_USB_SDP
- Add SoB from Frieder Schrempf

[U-Boot] [PATCH v2 1/3] mx6sabreauto: Remove CONFIG_SPL_DM to decrease the SPL size

[Sjoerd Simons]

The i.mx6 SPL binary cannot be bigger then 68K, while with the current
defconfig for sabreauto it's only about 56K as soon as USB support gets
added the size will overflows.

Unfortunately, it still fails with imx_usb_loader due to the lack of IVT.

Secure boot also needs IVT, so we need to find a way to insert IVT in
the FIT image.

Tested with UUU and it worked, so this is progress :-)

Small steps right; Ooi what imx_usb_loader configuration/commands are
you using to test this? (I find its config rather tricky to grasp).

One of the next things I will need to look at is actually secure boot..
That said why does imx_usb_loader if the board isn't locked?

I simply run:

sudo ./imx_usb SPL

and then

sudo ./imx_usb u-boot-dtb.img

I suggest you to try U-Boot 2019.01 on a mx6sabreauto first.

U-Boot 2019.01 is prior to the DM / fit conversion and loading SPL +
u-boot.img with the method above works fine.

Not sure what you mean by locked.

We have been using imx_usb_loader for a long time. After DM / fit
comvesion the IVT piece is not added into the final .img.

From the main Makefile:

ifdef CONFIG_SPL_LOAD_FIT
MKIMAGEFLAGS_u-boot.img = -f auto -A $(ARCH) -T firmware -C none -O u-boot \
-a $(CONFIG_SYS_TEXT_BASE) -e $(CONFIG_SYS_UBOOT_START) \
-n "U-Boot $(UBOOTRELEASE) for $(BOARD) board" -E \
$(patsubst %,-b arch/$(ARCH)/dts/%.dtb,$(subst ",,$(CONFIG_OF_LIST)))
else
MKIMAGEFLAGS_u-boot.img = -A $(ARCH) -T firmware -C none -O u-boot \
-a $(CONFIG_SYS_TEXT_BASE) -e $(CONFIG_SYS_UBOOT_START) \
-n "U-Boot $(UBOOTRELEASE) for $(BOARD) board"
MKIMAGEFLAGS_u-boot-ivt.img = -A $(ARCH) -T firmware_ivt -C none -O u-boot \
-a $(CONFIG_SYS_TEXT_BASE) -e $(CONFIG_SYS_UBOOT_START) \
-n "U-Boot $(UBOOTRELEASE) for $(BOARD) board"
u-boot-ivt.img: MKIMAGEOUTPUT = u-boot-ivt.img.log
CLEAN_FILES += u-boot-ivt.img.log u-boot-dtb.imx.log SPL.log u-boot.imx.log
endif

we  can see that the ivt is not added for the CONFIG_SPL_LOAD_FIT case.

I tried to change this logic, but so far was not able to make it work.

Right; I've used that method on a fair few boards but none of those use
FIT.

For loading the SPL mx6_usb_sdp_spl.conf of imx_usb_loader has:
`hid,uboot_header,1024,0x10000000,1G,0x00907000,0x31000`

So my guess was that it was simply failing as a fit image doesn't have
a uboot header ;). I did have a quick look at seeing how to convince
imx_usb_loader to upload a FIT image, but failed to do so (hence my
question). uuu turned to be simpler to get to comply :)

Sorry closing the device would be the right jargon for i.mx. My point
really is, isn't it something to be fixed in imx_usb_loader if it can't
upload unsigned FIT images rather then in u-boot?

Yes, I think imx_usb_loader needs to be fixed to load FIT images.

However, since the current FIT format for i.MX6 does not contain an
IVT, this would cause issues when running secure boot.

So in my opinion if we could change the i.MX6 FIT format to also add
an IVT, then I think we could fix the imx_usb_loader and secure boot
issues.

Test HW: i.MX6Q Display5 factory setup.



However, one thing puzzles me - the VID / PID used.When I run uuu
(mfgtools: SHA1: 13d187304f4faa473d2141409419c5b6f052addb):

I see that "Build in config" has following VID/PID:
        SDPU:    SPL             0x0525  0xb4a4  [0x0000..0x04ff] [1]
        SDPV:    SPL1            0x0525  0xb4a4  [0x0500..0x9998]
        SDPU:    SPL             0x0525  0xb4a4  [0x9999..0x9999]

But to make the SDPU command working I had to adjust it to be similar
to sabreauto (CONFIG_USB_GADGET_VENDOR_NUM=0x0525
CONFIG_USB_GADGET_PRODUCT_NUM=0xa4a5). Those match to "FB" (fastboot?).

Is this a bug or just the "Build in config" information is outdated?
With VID/PID set as for [1] (and as we use SDPU command, not FB), the
uuu doesn't connect to loaded SPL.



To make it working (on host):

cat << EOF > display5_recovery.lst
uuu_version 1.2.135
SDP: boot -f /srv/tftp/SPL
SDPU: write -f /srv/tftp/u-boot-dtb.img -addr 0x10000000
SDPU: jump -addr 0x10000000
SDPU: done
EOF

sudo ./uuu/uuu display5_recovery.lst

So u-boot for the spl does (arch/arm/mach-imx/spl.c):
```
int g_dnl_bind_fixup(struct usb_device_descriptor *dev, const char *name)
{
      put_unaligned(CONFIG_USB_GADGET_PRODUCT_NUM + 0xfff, &dev->idProduct);
``

Iotw with CONFIG_USB_GADGET_PRODUCT_NUM=0xa4a5 in the config when in
the SPL the product will be 0xb4a4, which uuu recognizes.

Once in the main u-boot image in principle you shoudl be able to use
`FB:`, however it doesn't seem `FB: ucmd` is supported for mainline u-
boot so...

So when looking through how secure boot can work from the SPL i can
accross e246bfcfe. Which explains the u-boot SPL expect a signed fit
image with roughly the following layout:

--------------------------------------------------
|     |     |     |   |           |     |        |
| FIT | FIT | FIT |   | U-BOOT    | ATF | U-BOOT |
| FDT | IVT | CSF |   | nodtb.bin |     |   DTB  |
|     |     |     |   |           |     |        |
--------------------------------------------------

The code aligns the IVT at 0x1000 and the standard CSF size is
0x2000. So one has to set CONFIG_FIT_EXTERNAL_OFFSET=0x3000 (assuming the FIT FDT <= 0x1000 bytes) to make CONFIG_SECURE_BOOT work in this setup (even if HAB is off and the image isn't signed). Otherwise the SPL won't pick up the correct location for all the external data.

Seems a bit ugly that the start offset of the external data can't be
introspected from the fdt blob, but oh well. 

The way this seems to work for i.mx8 is that the SECOND_LOADER command
sticks in a IVT header into the fit image. I assume some other tooling
can then stick the CSF data in the appropriate place (anyone have a
pointer?).

Now i guess the first question becomes whether the i.mx6 should follow
the same layout. And if so how to integrate it properly (teach mkimage
about handling firmware_ivt for fit images?). 

Relatedly i was looking for a good description of using HAB for loading
the OS in FIT images, but failed to find a good document. pointers
welcome.

Thanks for looking at this issue.

We are using similar structure in NXP U-Boot for i.MX8M devices, you
can use dd tool as explained in document below:
https://source.codeaurora.org/external/imx/uboot-imx/tree/doc/imx/habv4/guides/mx8m_mx8mm_secure_boot.txt?h=imx_v2018.03_4.14.98_2.0.0_ga#n301

IMHO we should follow the same layout as in i.MX8M, as far as I know
in NXP BSP this is handled by imx-mkimage tool:
https://source.codeaurora.org/external/imx/imx-mkimage/?h=imx_4.14.98_2.0.0_ga

Perhaps we can try similar with mkimage tool included in upstream U-Boot?

For HAB API usage you can take a look in HABv4 RVT Guidelines and
Recommendations application note:
https://www.nxp.com/docs/en/application-note/AN12263.pdf

The U-Boot docs in NXP BSP U-Boot also provides an overview:
https://source.codeaurora.org/external/imx/uboot-imx/tree/doc/imx/habv4?h=imx_v2018.03_4.14.98_2.0.0_ga

THat's a quite useful document indeed to explain the mx8m setup a bit
more; Would be lovely to get that in upstream u-boot!

Though from what i can tell mx8m secure boot isn't there yet upstream,
at least judging by the fact there is no correct definition of the RVT
base address for those upstream yet ;)

Right i'd hope the i.mx8m specific bits in u-boot already do that as
well; but for i.MX6 those are overkill since there isn't one big
flash.bin but two seperate bits of data (Though from the documentation
it feels like that might be the case for i.mx8 as well? As there
doesn't seem to be a reason apart from flashing convenience to put the
SPL and the u-boot images in one big file)

Right all those assume you're using a (z)Image with the IVT/CSF
appended; None of those describe a conventional layout for a FIT image.

I do observe another issue - one of my "factory" board setup is not
using (till now) OF_CONFIG.

Without u-boot.img being a FitImage wrapped, the imx_usb_loader works
correctly (with current mainline).

After this change I do see the issue with imx_usb_loader.
Unfortunately, applying this patch doesn't help.

I will investigate this issue further tomorrow.

Does this look good to you?

Could we have this for 2019.09? It fixes the loading of U-Boot via SDP

Thanks

I have no comments, but from the discussion I felt there are still some
issues and I left it over.

Lukasz reported an issue initially, but after adjusting the VID / PID
he managed to get it to work.

Lukasz, please confirm.

I can confirm that I made it working on v2019-rc3 (on display5) after
adjusting VID/PID with NXP's 'uuu' utility to recovery i.MX6Q board.

Do you think this one could be applied?

Without it, I can not load a fit image via USB on imx6sabresd.
