microblaze: Disable heartbeat/enable emaclite in defconfigs

I need to disable heartbeat function because this features
breaks testing in Qemu.

microblaze: Support simpleImage.dts make target

2009-09-24T08:28:22+00:00

Instead of remembering to specify DTB= on the make commandline, this commit
allows the much friendlier make simpleImage.
where .dts is expected to be found in arch/microblaze/boot/dts/
The resulting vmlinux, with the compiled DTS linked in, will be copied to
boot/simpleImage.

This mirrors the same functionality as on PowerPC,
albeit achieving it in a slightly different way.

+ strip simpleImage file
The size of output file is very similar to linux.bin.

vmlinux - full elf without fdt blob
simpleImage..unstrip - full elf with fdt blob
simpleImage. - stripped elf with fdt blob

Add symlink to generic system.dts in platform folder

headers: utsname.h redux

2009-09-24T01:13:10+00:00

* remove asm/atomic.h inclusion from linux/utsname.h --
   not needed after kref conversion
 * remove linux/utsname.h inclusion from files which do not need it

NOTE: it looks like fs/binfmt_elf.c do not need utsname.h, however
due to some personality stuff it _is_ needed -- cowardly leave ELF-related
headers and files alone.

arches: drop superfluous casts in nr_free_pages() callers

2009-09-22T14:17:34+00:00

Commit 96177299416dbccb73b54e6b344260154a445375 ("Drop free_pages()")
modified nr_free_pages() to return 'unsigned long' instead of 'unsigned
int'.  This made the casts to 'unsigned long' in most callers superfluous,
so remove them.

microblaze: Fix _start symbol to physical address

2009-09-22T08:11:08+00:00

_start is setup to physical kernel start address.
This caused that when you load vmlinux (with MMU kernel)
via XMD program counter (pc) is setup correctly
and then you can write con and start kernel.
