[U-Boot] U-Boot on nyan-big via legacy boot

[SimonH]

Hi Simon,

I'm trying to boot a Linux distribution of choice on the Acer 
CB5-311-T9XM (nyan-big). I applied your patches from last Wednesday (v4, 
without the display driver) and flashed the patched uboot to the 
RW_LEGACY section after running this script with some objcopies 
(https://chromium.googlesource.com/chromiumos/overlays/chromiumos-overlay/+/master/sys-boot/chromeos-bootimage/files/build_cb_legacy_uboot.sh). 
Afterwards I jumped into the legacy section with Ctrl+L. Unfortunately 
it just resets the board after some seconds. The reset cause is: 
"reset-pin" and "hard". Find the EC UART output at the bottom. Using the 
norrin.board pinmux instead of nyan-big.board didn't change the 
behaviour (GPIO PI5).

Do you have an idea what I'm doing wrong?

Regards,
Simon Hoinkis
