Among other things, a 2GB or more board will fail 'make check' on a 32-bit host, because 'make check' tries to start all board models, and 32-bit hosts can only handle up to 2047MB of guest RAM. thanks -- PMM

The Raspberry Pi 4 uses a BCM2711 SoC (based on a BCM2838). The SoC can handle up to 8GiB of SDRAM, but we limit it to 4GiB (no 8GiB models in the market yet).
