Re: [PATCH 0/4] Add a pcd PcdBootManagerInBootOrder to control whether BootManager is in BootOrder

["Gao, Zhichao" <zhichao.gao@intel.com>]

Ray,

You are right. I didn't view the implementation of BmGetFreeOptionNumber. Only use it base on its comments.
If new options are added after BootManagerMenuApp with the pcd's value FALSE then it would be overwriten.

3/4 would remove the BootManagerMenuApp option from Boot#### and BootOrder. But adding it to BootMenu (i.e. BootOrder) is done by platform code, platform usually add it at PlatformBootManagerAfterConsole function. So I think we are able to choose whether to add it or not. Both changing the pcd or do not add it in the platform (actually PlatformBootManagerLib) can match this requirement.

So I think the requirement is keeping all the features of BootMenuApp (such as hotkey boot, boot next and so on) except showing it in the BootMenu.

This patch is inappropriate. But firstly, did I misunderstand the requirement?

Thanks,
Zhichao
