	u-boot: support merging .cfg files for UBOOT_CONFIG

	U-boot recipe supports .cfg files in SRC_URI, but they would be merged
	to .config during do_configure only when UBOOT_MACHINE is set, we
	should also support merging .cfg files for UBOOT_CONFIG.

The intension of 4fde8c8 looks more than append delta-config snippets to
u-boot config and should probably be rewritten to express that much better
than implicitely assume all "*.cfg" are for merging into .config.

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
