[meta-intel] [PATCH] intel-common: Add a README

[Darren Hart]

Add a README describing the intel-core* (intel-common) BSPs and the
Linux kernel package architecture. Includes a list of currently tested
BSPs compatible with the intel-common BSPs.

+The intel-* BSPs, also known as the intel-common BSPs, provide a few
+carefully selected tune options and generic hardware support to cover
+the majority of current Intel CPUs and devices. The naming follows the
+convention of intel-<TUNE>-<BITS>, where TUNE is the gcc cpu-type (used
+with mtune and march typically) and BITS is either 32 bit or 64 bit.
+
+intel-core2-32
+This BSP is optimized for the Core2 family of CPUs as well as all Atom
+CPUs prior to the Silvermont core.
+
+intel-corei7-64
+This BSP is optimized for Nehalem and later Core and Xeon CPUs as well
+as Silvermont and later Atom CPUs, such as the Baytrail SoCs.
+
+These BSPs use what we call the intel-common Linux kernel package
+architecture. This includes core2-32-intel-common and
+corei7-64-intel-common. These kernel packages can also be used by any of
+the BSPs in meta-intel that choose to include the
+intel-common-pkgarch.inc file. To minimize the proliferation of vendor
+trees, reduce the sources we must support, and consolidate QA efforts,
+all BSP maintainers are encouraged to make use of the intel-common Linux
+kernel package architecture.
+
+Of the BSPs presently included in meta-intel, the following have passed
+initial testing with the intel-common BSPs (rather than the named BSP):
+
+For intel-corei7-64:
+    crystalforest-server
+    crystalforest-gladden
+    haswell-wc
+    nuc (requires manual audio configuration)
+    romley
+    sugarbay
+
+For intel-core2-32:
+    crownbay-noemgd
+    emenlow
