Murali, Ok thanks for the clarification. There are a number of ARM UEFI reference platform builds at edk2.svn.sourceforge.net so it probably make sense to host your platform there as well. This makes it easy to take in enhancements coming to edk2 like IPv6 net boot and USB 3.0 host controller support.
I have had some discussions with Olivier about different approaches to booting Linux from UEFI firmware. The current ARM code can boot into Linux directly from a customized BDS, this is the closed/embedded model where the boot firmware and OS are tightly coupled. There is also work underway to support the standard UEFI boot mechanism using UEFI Linux OS Loader, enabling open systems where the boot firmware and OS are independent. This will be a key milestone since it allows us to really take advantage of the modularity of UEFI.

I am using the BeagleBoardPkg as a starting point to customize for Soc-specific requirements. In order to sync upstream of UEFI Fw I referred the mailing list and used -- 11950 revision. the plan is to setup the UEFI FW and boot to the Linux images using ATAG list.

Or when you say bootloader do you mean a new UEFI firmware variant starting at or near the reset vector? Terminology is getting a bit confusing here since other boot systems may not make a formal distinction, but from a UEFI Spec point of view the platform firmware and OS loader are separate entities. If you're referring to a UEFI loader application I would expect this to be generic and theoretically able to boot on any ARM UEFI system. I would expect SoC-specific stuff to be handled in the UEFI firmware environment.

I started this task with BeagleBoardPkg project in tianocore . Please advice if there is anything else that I need to patch for including my updates. Regards Murali 2011/8/26 Cohen, Eugene <[email protected]<mailto:[email protected]>> Girish, Please coordinate this with Olivier Martin from ARM, I believe he is already working on a UEFI loader. My guess is that we should be able to host this in the existing sourceforge SVN repository used for edk2. I think it would make sense use of the existing build system, interfaces and libraries already in edk2. If people wanted to we could probably do some kind thing where a Liano git repo imports the edk2 svn tree. Thanks!

I am responsible for the supporting Uefi for samsung platform. Can you please let me know when the git repository will be available to upstream the UEFI.
