Hi Qemu-devel,

This is my first attempt in Qemu.
Please let me know am doing correct or not.
SoC is cortex M3 based so no bootrom stuff and unlike other
SoCs Qemu need not load dtb and kernel in DDR. Hence am using
u-boot (supplied with -kernel) as bootloader in eNVM and it loads
kernel from SPI flash to DDR same like real hardware scenario.
Also let me know any other Maintainers need to be CCed.

Thank you,
Sundeep
