This allow for convenient use of QEMU machine to test loading of UBI filesystem. There are a couple of changes made together of this which are required:
The malloc must be at least 512 KiB to allow the use of UBI filesystem. We are going to enable it in a next patch.
MTD_DEVICE must be enabled, otherwise we get missing symbols during the build
Following configs were change:
- vexpress_aemv8a_dram_defconfig

I don't have much to say about the enabling of the UBI for some platforms that I have my doubts that QEMU emulates them correctly, but I guess it should be harmless. What I have issues here is you saying in the commit message "The malloc must be *at least* 512 KiB" but here you make it *exactly* 512KiB, ignoring the CONFIG_ENV_SIZE. Would it not be better to keep the CONFIG_SYS_MALLOC_LEN to be (CONFIG_ENV_SIZE + 512 * 1024)?
