Since commit 9e3c0174da842 ("pico-imx7d: Add LCD support") loading U-Boot via USB download mode causes the following hang:
SDP: initialize... SDP: handle requests... Downloading file of size 527088 to 0x877fffc0... done Jumping to header at 0x877fffc0 Header Tag is not an IMX image
U-Boot 2019.04-rc4-00047-gcfb3e102c4 (Mar 23 2019 - 10:45:10 -0300)
CPU: Freescale i.MX7D rev1.2 1000 MHz (running at 792 MHz) CPU: Commercial temperature grade (0C to 95C) at 40C Reset cause: POR Board: i.MX7D PICOSOM I2C: ready DRAM: 512 MiB
(Hangs here)
When booting from eMMC such hang does not happen and currently we don't have a proper fix for this. Also, this hang in USB download mode only happens with the older version of the board that has 512MB of memory.
As a temporary workaround, remove video support so that users do not have a negative experience in case they brick their board and want to recover from USB.
We can re-add video support later when a proper fix is in place.
