BB ROM 29/04/21 fail

Today’s ROM (29/04/21) for the BeagleBoard seems to be broken in that both the drive lamps light solid but that’s all. Display (lamp) shows no signal and keyboard lamps don’t flash. Revert to previous ROM & all’s well.

Looks like I might have broken compressed ROM support – a local build works fine, but not if I compress it.

This should fix it: https://gitlab.riscosopen.org/RiscOS/Sources/Kernel/-/merge_requests/54

Yup!
