Ard Biesheuvel c653fc2a91 ArmPkg/ArmLib: add accessor function for Cache Writeback Granule 
Add a function to ArmLib that provides access to the Cache Writeback
Granule (CWG) field in CTR_EL0. This information is required when
performing non-coherent DMA.

Ard Biesheuvel fbf658ebc8 ArmPkg/ArmLib: retrieve cache line length from CTR not CCSIDR 
The stride used by the cache maintenance by MVA instructions should
be retrieved from CTR_EL0.DminLine and CTR_EL0.IminLine, whose values
reflect the actual geometry of the caches. Using CCSIDR for this purpose
violates the architecture.

Also, move the line length accessors to common code, since there is no
need to keep them separate between ARMv7 and AArch64.

Ard Biesheuvel f97ab1bbf4 ArmPkg/ArmLib: remove CCSIDR based cache info routines 
The ARM architecture does not allow the actual geometries of the caches
to be inferred from the CCSIDR cache info system register, since the
geometry it reports is intended for performing cache maintenance by
set/way and nothing else. Since the ArmLib cache info routines are
based solely on CCSIDR contents, they should not be used.

AJFISH 2ef2b01e07 Adding support for BeagleBoard. 
ArmPkg - Supoprt for ARM specific things that can change as the architecture changes. Plus semihosting JTAG drivers.
EmbeddedPkg - Generic support for an embeddded platform. Including a light weight command line shell.
BeagleBoardPkg - Platform specifics for BeagleBoard. SD Card works, but USB has issues. Looks like a bug in the open source USB stack (Our internal stack works fine).
