Major layout change to the packages directory

Having one monolithic packages directory makes it hard to find things
and is generally overwhelming. This commit splits it into several
logical sections roughly based on function, recipes.txt gives more
information about the classifications used.

The opportunity is also used to switch from "packages" to "recipes"
as used in OpenEmbedded as the term "packages" can be confusing to
people and has many different meanings.

Not all recipes have been classified yet, this is just a first pass
at separating things out. Some packages are moved to meta-extras as
they're no longer actively used or maintained.

+Subject: ARM: NEON L1 cache bug workaround (erratum 451034)
+X-Git-Url: http://git.mansr.com/?p=linux-omap;a=commitdiff_plain;h=26023493baf13e0a67fd6cf08d87be5ff6f7c56d

+ARM: NEON L1 cache bug workaround (erratum 451034)
+
+On Cortex-A8 r1p0 and r1p1, executing a NEON store with an integer
+store in the store buffer, can cause a processor deadlock under
+certain conditions.
+
+Executing a DMB instruction before saving NEON/VFP registers and before
+return to userspace makes it safe to run code which includes similar
+counter-measures.  Userspace code can still trigger the deadlock, so
+a different workaround is required to safely run untrusted code.
+
+See ARM Cortex-A8 Errata Notice (PR120-PRDC-008070) for full details.
