Boot Guard Support
by Javier Santos Romo
Dear Everyone,
I have seen that trying to stitch SBL binary with StitchLoader.py and boot guard enabled, produces a binary which doesn´t boot (I´m using a Leaf Hill Board). Reding documentation, I have seen that currently boot guard is not supported. Does SBL support this feature? If answer is no, do you have any timeline to add support to this feature?
Thanks,
Javier

Roadmap for support other architectures?
by Игорь Данилов
Hello!
First, do you have any roadmap for support other Intel chips (I'm currently
interested in Skylake)?
Second question: do you have plans - it's is possible at all - to support
other ISA (arm, for example).

How to update Mem info in E820 Table
by zhou_c@hoperun.com
Hi Guys,
Recently, I got an issue on UP2 boards after deploying latest SBL on it. Linux kernel only got 2G memory. But there is 8G DDR physical memory on board.
After checking dmesg:
[ 0.000000] BIOS-e820: [mem 0x0000000000000000-0x000000000008ffff] usable

And SBL log shows the same case:
Call FspSiliconInit ...

MP Init (Run)
Actually, there is another DDR memory block (mem 0x0000000100000000-0x000000027fffffff) on the board. Could any one provide some methods to update the SBL Memory Info, please?
