i wasn't able to reproduce this issue with the RPi 3B+ so far and i
don't have any OMAP hardware:

Linux 5.3 (bcm2835_defconfig) + FW 2019-02-12 => okay
Linux 5.3 (bcm2835_defconfig + ZONE_DMA) + FW 2019-02-12 => okay
Linux 5.5-rc1 (bcm2835_defconfig) + FW 2019-02-12 => okay
Linux 5.5-rc1 (multi_v7_defconfig) + FW 2019-02-12 => okay

So please provide more information about your RPi 3B+ setup:

- VC firmware version
- additional bootloader (U-Boot)
- boot source (SD card, USB, network)
- kernel config

Did you tested the mainline kernel or the letux kernel?

Best regards
Stefan
