I am trying to boot a RPI4 with the 5.6 kernel from unstable, but it
fails to boot (while it worked with 5.5 from unstable).

What I'm seeing with 5.5, but not with 5.6, is:
[    4.500333] mmc1: SDHCI controller on fe340000.emmc2 [fe340000.emmc2] using ADMA
[    4.500585] mmc0: queuing unknown CIS tuple 0x80 (3 bytes)
[    4.577842] mmc0: new high speed SDIO card at address 0001
[    4.610694] mmc1: new ultra high speed DDR50 SDHC card at address aaaa
[    4.618812] mmcblk1: mmc1:aaaa SC16G 14.8 GiB
[    4.629268]  mmcblk1: p1 p2

Did you also see that issue? Was it fixed by enabling
CONFIG_PCIE_BRCMSTB, or is that a different issue?

Thanks,

Lucas
