Add support for trusted boot using a vTPM 2.0 on the IBM IEEE1275
PowerPC platform. With this patch grub now measures text and binary data
into the TPM's PCRs 8 and 9 in the same way as the x86_64 platform
does.
This patch requires Daniel Axtens's patches for claiming more

This was apparently 'required by some firmware': commit dc9468500919
("2007-02-12 Hollis Blanchard ").
It's not clear what firmware that was, and what platform from 14 years ago
which exhibited the bug then is still both in use and buggy now.
It doesn't cause issues on

When working on memory, it's nice to be able to test your work.
Add a memtest module. When compiled with --enable-mm-debug, it exposes
3 commands:
* lsmem - print all allocations and free space in all regions
* lsfreemem - print free space in all regions
*
).

On PowerVM, the first time we boot a Linux partition, we may only get
256MB of real memory area, even if the partition has more memory.
This isn't enough to reliably verify a kernel. Fortunately, the Power
Architecture Platform Reference (PAPR) defines a method we can call
From: Daniel Axtens
On powerpc-ieee1275, we are running out of memory trying to verify
anything. This is because:
- we have to load an entire file into memory to verify it. This is
difficult to change with appended signatures.
- We only have 32MB of heap.
- Distro kernels are now often

From: Paulo Flabiano Smorigo
This is an implementation of IBM client architecture (CAS) reboot for GRUB.
There are cases where the POWER firmware must reboot in order to support
specific features requested by a kernel. The kernel calls
ibm,client-architecture-support and it may either return or
Sometimes, when booting from a very busy SAN, the access to the
disk can fail and then grub will eventually drop to grub prompt.
This scenario is more frequent when deploying many machines at
the same time using the same SAN.
This patch aims to force the ofdisk module to retry the open or
read

grub-ofpathname doesn't work with fibre channel because there is no
function currently implemented for it.
This patch enables it by prividing a function that looks for the port
name, building the entire path for OF devices.

The grub-ofpathname and hint feature for ieee1275 are not working since there
is no code implemented to get the information needed about fibre channel
devices and device mapper.
This patch series implements the codes for both groups of devices and with them
we can get the --hint-ieee1275
From: Diego Domingos
this patch enables the device mapper discovery on ofpath.c. Currently,
when we are dealing with a device like /dev/dm-* the ofpath returns null
since there is no function implemented to handle this case.
This patch implements a function that will look into /sys/block/dm
. This close will be responsible
to request the firmware to actually close the disk.
Yet, this patch modifies the grub_ofdisk_get_block_size function, avoiding open
and close calls inside of it.
Thank you Michael Chang (mch...@suse.com) for all support.
