"Synchronous Abort" handler and reboot loop on rpi

I think this one could be due to the newer u-boot - 2020.10+dfsg-1
It's coming into focal dailies because proposed is enabled there, but I also tried to boot an rpi400 with bionic on an older uboot, then enable proposed and *only* update u-boot. After updating, I get this boot loop there too.

Finally managed to replicate this and confirmed it also occurs on the Pi 4 8Gb, but *only when there's no monitor attached*. Stick a monitor on it, it works (which was the reason I having troubles reproducing this). Couldn't replicate it on the CM4, but did find another issue with the latest u-boot being unable to identify the eMMC device.

Anyway, this issue turns out to be caused by the addition of PCI support to the u-boot config; disable that and everything's fine again. I'm currently prepping a trivial patch to the hirsute version (and another one to fix the aforementioned CM4 issue), which we can then SRU if I haven't managed to break something *else* in the meantime :)

Attaching a patch against the hirsute version which fixes this (and the aforementioned CM4 failure); I'm prepping separate patches for SRU to bionic, focal, and groovy.

This bug was fixed in the package u-boot - 2020.10+dfsg-1ubuntu6

---------------
u-boot (2020.10+dfsg-1ubuntu6) hirsute; urgency=medium

  * Add d/p/rpi-8gb-pci.patch for Pi400 and Pi4-8Gb support (LP: #1906552)
  * Add d/p/rpi-cm4-sdhci.patch for CM4 eMMC support
  * Add d/p/rpi-maxargs.patch for new Core 18 boot-env (LP: #1910094)
  * Remove redundant d/targets entries

Tested on focal with rpi400. After updating, I'm now able to boot.

Confirmed bionic boots after the update to proposed on rpi400

Current uc20 candidate image has the updated uboot - this boots fine on both cm4-lite and rpi400

Worked on groovy before the update, but also works after updating to proposed
