[U-Boot] ARM mach-types.h new procedure

[Jean-Christophe PLAGNIOL-VILLARD]

Hi all,

	I'll announce how mach-types.h will be update on arm.

	The mach-types.h will be sync with the kernel on each kernel's
	release. If you need a sync between two kernel's release please send
	a request as this

	Subject:	ARM mach-types.h sync request
	Body:		comment

	In most of the case, this will be not needed.

Best Regards,
J.
