[PATCH v1] colibri_imx7: disable HAB and CAAM support

[PATCH v1] colibri_imx7: disable HAB and CAAM support

[Igor Opaniuk]

From: Igor Opaniuk <igor.opaniuk@toradex.com>

Currently Colibri iMX7 NAND version doesn't boot at all with
HABv4 support enabled. If CSF section is included in the final
imx binary, BootROM every time switches to usb recovery mode.
However eMMC version of the same SoM works without any issues.

Disable HAB and CAAM support for now until the problem is properly
investigated and fixed.

For additional details about the problem check [2], [3], [4].

This issue is also happening with i.MX6ULL, seems that padding the
U-Boot binary to the size defined in boot data is addressing this
issue.

Please follow example below.

1. Dump boot data:

$ hexdump u-boot-dtb.imx | head
0000000 00d1 4020 0000 8780 0000 0000 f42c 877f
0000010 f420 877f f400 877f 6000 878d 0000 0000
0000020 f000 877f b000 000d 0000 0000 01d2 40e8
0000030 01cc 04e4 0c02 6840 ffff ffff 0c02 6c40

IVT self = 0x877ff400
Boot data addr = 0x877ff000
Boot data size = 0x000db000

2. Calculate image size:

Image offset = IVT self(0x877ff400) - Boot data addr(0x877ff000) = 0x400
Total image size = Boot data size(0x000db000) - Image offset(0x400) = 0xdac00

3. Pad U-Boot image:

$ objcopy -I binary -O binary --pad-to 0xdac00 --gap-fill=0x00
u-boot-dtb.imx u-boot-dtb.imx.pad

Could you please try similar in your i.MX7D board?

Thanks,
Breno Lima

Finally, it works!

Thanks a lot for your help! This should be documented (I'll create a
patch for this)
or padding should implicitly be done in makefiles when building the
final imx image,
including initial padding for 0x400, like here [1].

Regards,
Igor

I left [1] in my queue and I have always asked myself if we really need
it. Frankly speaking, I prefer that the case should be clearly
documented instead of adding an initial padding. Padding could forbid
(or makes more difficult) to pack u-boot inside another container.

Stefano

I would say that [1] is a dirty workaround. I'm currently trying to
understand if it's
possible to address both issues in tools/imximage.c, so please just ignore [1].
