EmbeddedPkg/AndroidBoot: boot android kernel from storage
Add an android kernel loader that could load kernel from storage device. This android boot image BDS add addtitional cmdline/dtb/ramfs support besides kernel that is introduced by Android boot header. This patch is derived from Haojian's code as below link. https://patches.linaro.org/patch/94683/ Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Jun Nie <jun.nie@linaro.org> Reviewed-by: Leif Lindholm <leif.lindholm@linaro.org>
