		+	== r5891: Move configuration values from romstage.c to Kconfig ==
		+
		+	Applicable if: local changes or additions to i945 based boards
		+
		+	Values were moved to Kconfig to have them available in all compilation units, not just romstage.c. In particular:
		+	* CHIPSET_I945GM -> CONFIG_I945GM
		+	* CHIPSET_I945GC -> CONFIG_I945GC
		+	* CHANNEL_XOR_RANDOMIZATION, OVERRIDE_CLOCK_DISABLE, MAXIMUM_SUPPORTED_FREQUENCY -> CONFIG_*
		+
		+	If your changes or additions use them, you'll have to adapt your changes. If you define the old variants in a romstage.c, you'll have to move them to Kconfig. See kontron/986lcd-m as a model.
		+
		+	== r5893: Split I945 northbridge to I945GC and I945GM ==
		+
		+	Applicable if: local changes or additions to i945 based boards
		+
		+	To simplify configuration, we now support two northbridges, i945GC and i945GM in the Kconfig system, instead of i945 with the GM or GC modifiers as separate attribute. The code is still shared as it's mostly the same.
		+
		+	To adapt boards, change NORTHBRIDGE_INTEL_I945 in Kconfig to NORTHBRIDGE_INTEL_I945GC or NORTHBRIDGE_INTEL_I945GM as appropriate and remove the I945GC or I945GM attribute (introduced in r5891)
		+
		+	== r5898: Rename CACHE_AS_RAM_ADDRESS_DEBUG to CONFIG_DEBUG_CAR ==
		+
		+	Applicable if: local changes or additions to AMD based boards
		+
		+	If you set CACHE_AS_RAM_ADDRESS_DEBUG in your romstage.c to get verbose output in CAR setup, you now have to select DEBUG_CAR in Kconfig instead.
		+
		+	== r5910: Move out .c includes from i945 (and some other boards) ==
		+
		+	Applicable if: local changes or additions to CAR boards
		+
		+	Instead of including sources in romstage.c, they're now compiled as separate units. r5910 does this for i945 based boards and on all CAR boards for <code>src/lib/ramtest.c</code>.
		+	To adapt, remove the corresponding includes from your romstage.c. You might have to include header files instead, as replacement to ramtest.c <code>lib.h</code> is a likely candidate.
		+
		+	== r5911: Move out usbdebug .c includes from CAR boards ==
		+
		+	Applicable if: local changes or additions to CAR boards
		+
		+	If your board supports the USB debug port, you will have to remove the related source include statements (two: one for the chipset, one for the generic code) and include <code>usbdebug.h</code> instead.

		+

		+
		+	Various build system variables are renamed, and their use has changed too:
		+	* initobjs-y is now romstage-y
		+	* objs-y is now ramstage-y
		+	* driver-y keeps the name but changes meaning
		+	* smmobj-y is now smm-y

		+	For most scenarios, it will be sufficient to change (for example) <code>initobjs-y += foo.o</code> in <code>romstage-y += foo.c</code>.
