DuetPkg: Remove DuetPkg
DuetPkg depends on Legacy BIOS to provide a UEFI environment. It was invented in the era when UEFI environment is hard to find. Since now UEFI is very popular in PC area, we could stop the official support of this package and remove it from the master. https://bugzilla.tianocore.org/show_bug.cgi?id=1322 Cc: Ruiyu Ni <ruiyu.ni@intel.com> Cc: Hao Wu <hao.a.wu@intel.com> Contributed-under: TianoCore Contribution Agreement 1.1 Signed-off-by: Shenglei Zhang <shenglei.zhang@intel.com> Reviewed-by: Hao Wu <hao.a.wu@intel.com> Reviewed-by: Ruiyu Ni <ruiyu.ni@intel.com>

Routine Description:
|
||||
|
||||
This routine adds the PPI/Protocol Hobs that are consumed by the DXE Core.
|

Normally these come from PEI, but since our PEI was 32-bit we need an
|
||||
alternate source. That is this driver.

|
||||
This driver does not consume PEI or DXE services and thus updates the
