df21fff504 Provide __bss_start and _end symbols in grub-mkimage.
For this ensure that all bss sections are merged.

We need this to correctly prelink non-PE relocatable images.

73a9c742fe Encapsulate image layout into a separate structure.
Currently we pass around a lot of pointer. Instead put all relevant data
into one structure.

dd3969e7ec mkimagexx: Split PE and generic part for relocations.
As a preparation for U-Boot relocations, split emitting PE-relocations
from parsing source ELF-relocations.

36212460d3 mkimage.c: Split into separate files.
util/grub-mkimagexx.c is included in a special way into mkimage.c.
Interoperation between defines makes this very tricky. Instead
just have a clean interface and compile util/grub-mkimage*.c separately
from mkimage.c

2ebef43cf6 bsd: Ensure that kernel is loaded before loading module.
kernel_type may be set to the type of failed kernel. This patching-up is
easier than to reflow kernel loading routines.

b00e4c2bd9 efidisk: prevent errors from diskfilter scan of removable drives
Map EFI_NO_MEDIA to GRUB_ERR_OUT_OF_RANGE that is ignored by diskfilter. This
actually matches pretty close (we obviously attempt to read outside of media)
and avoids adding more error codes.

This affects only internally initiated scans. If read/write from removable is
explicitly requested, we still return an error and text explanation is more
clear for user than generic error.

eb9f401fc1 net: fix ipv6 routing
ipv6 routing in grub2 is broken, we cannot talk to anything outside our local
network or anything that doesn't route in our global namespace.  This patch
fixes this by doing a couple of things

1) Read the router information off of the router advertisement.  If we have a
router lifetime we need to take the source address and create a route from it.

2) Changes the routing stuff slightly to allow you to specify a gateway _and_ an
interface.  Since the router advertisements come in on the link local address we
need to associate it with the global address on the card.  So when we are
processing the router advertisement, either use the SLAAC interface we create
and add the route to that interface, or loop through the global addresses we
currently have on our interface and associate it with one of those addresses.
We need to have a special case here for the default route so that it gets used,
we do this by setting the masksize to 0 to mean it encompasses all networks.
The routing code will automatically select the best route so if there is a
closer match we will use that.

With this patch I can now talk to ipv6 addresses outside of my local network.
Thanks,

bc220962e3 ieee1275: prevent buffer over-read
Prevent buffer over-read in grub_machine_mmap_iterate. This was
causing phys_base from being calculated properly. This then
caused the wrong value to be placed in ramdisk_image within
struct linux_hdrs. Which prevented the ramdisk from loading on
boot.

Newer SPARC systems contain more than 8 available memory entries.

For example on a T5-8 with 2TB of memory, the memory layout could
look like this:

625934ec0f menu_entry: Disable cursor during update_screen()
When running grub in a VGA console of a KVM pseries guest on PowerPC,
you can see the cursor sweeping over the whole line when entering a
character in editor mode. This is visible because grub always refreshes
the whole line when entering a character in editor mode, and drawing
characters is quite a slow operation with the firmware used for the
powerpc pseries guests (SLOF).
To avoid this ugliness, the cursor should be disabled when refreshing
the screen contents during update_screen().
