u-boot: remove UBOOT_MACHINE and COMPATIBLE_MACHINES
oe-core does not define any machines, so it does not make sense to
add machine specific information in the oe-core u-boot recipe and
infrastructure. Also note that COMPATIBLE_MACHINES is not easily extended due to
its regex syntax: "(machine_a|machine_b)", making it difficult to extend the
u-boot recipe in bbappend files without resorting to machine specific overrides.
Remove COMPATIBLE_MACHINES and the default UBOOT_MACHINE from the recipe and
insert some anonymous python into u-boot.inc to raise SkipPackage if
UBOOT_MACHINE is not set (this ensures 'world' still works for machines that
can't build u-boot).
UBOOT_MACHINE must now be specified in each machine config that requires u-boot.
This is an improvement over requiring machine specific overrides in every BSP
layer's u-boot_git.bbappend file. For example, a beagleboard machine config
currently contains:
UBOOT_ENTRYPOINT = "0x80008000"
UBOOT_LOADADDRESS = "0x80008000"
With this change, it must now contain:
UBOOT_MACHINE = "omap3_beagle_config"
UBOOT_ENTRYPOINT = "0x80008000"
UBOOT_LOADADDRESS = "0x80008000"
So long as the SRC_URI in the base recipe can build a working u-boot for a given
machine, there is no need to create a u-boot_git.bbappend file. If additional
patches are deemed necessary, a BSP layer creates a u-boot_git.bbappend file and
extends the SRC_URI to include general or machine specific backports.
Note: I used bb.note() instead of bb.debug() to ensure the message at least
makes it to the console. From what I could gather, bb.debug() doesn't
go anywhere during recipe parsing.
