3e303f748c fdt_support: Add multi-serial support for stdout fixup
Currently fdt_fixup_stdout() is using hard-coded CONFIG_CONS_INDEX
constant. With multi-serial support, the CONS_INDEX may no longer
represent actual console, so we should try to extract port number
from the current stdio device name instead of always hard-coding the
constant value.

d535a49300 fdt: Fix fdt padding issue for initrd mem_rsv
Its possible that we end up with a device tree that happens to be a
particular size that after we call fdt_resize() we don't have any
space left for the initrd mem_rsv.

Fix this be adding a second mem_rsv into the size calculation.  We
had one to cover the fdt itself and we have the potential of adding
a second for the initrd.

c088a108c7 fdt_resize(): fix actualsize calculations with unaligned blobs
The code in fdt_resize() to extend the fdt size to end on a page boundary
is wrong for fdt's not located at an address aligned on a page boundary.
What's even worse, the code would make actualsize shrink rather than grow
if (blob & 0xfff) was bigger than the amount of padding added by ALIGN(),
causing fdt_add_mem_rsv to fail.

Fix it by aligning end address (blob + size) to a page boundary instead.
For aligned fdt's this is equivalent to what we had before.

56844a22b7 powerpc: Fix bootm to boot up again with a Ramdisk
Commit 2a1a2cb6 didnt remove the dummy mem reservation in fdt_chosen,
and this stopped Linux from booting with a Ramdisk. This patch fixes
this, by deleting the useless dummy mem reservation.

When booting with a Ramdisk, a fix offset FDT_RAMDISK_OVERHEAD is now
added to of_size, so we dont need anymore a dummy mem reservation.

I measured the value of FDT_RAMDISK_OVERHEAD on a MPC8270 based
system (=0x44 bytes) and rounded it up to 0x80).

43ddd9c820 Remove deprecated CONFIG_OF_HAS_UBOOT_ENV and CONFIG_OF_HAS_BD_T
These defines embedded the u-boot env variables and/or the bd_t structure
in the fdt blob.  The conclusion of discussion on the u-boot email list
was that embedding these in the fdt blob is not useful: there are better
ways of passing the data (in fact, the fdt blob itself replaces the
bd_t struct).

The only board that enables these is the stxxtc and they don't appear
to be used by linux.
