Subject: [PATCH 8/8] ARM: dts: bcm283x: add compatible picked up by U-Boot
Without brcm,bcm2835-pl011 in compatible U-Boot uses the regular PL011
driver which seems to crash when enable_uart=1 is not used. Using
brcm,bcm2835-pl011 works around that and does not affect Linux since its
not using that compatible string.
