Newer gcc's might be configured to enable autovectorization by default.
If we happen to build with one of those compilers we will get SPE
instructions in random code.
-mno-spe disables the compiler for automatically generating SPE
instructions without our knowledge.

Rename init_addr and init_ext_addr to match the docs between
85xx and 86xx. Both now use 'init_addr' and 'init_ext_addr'.

* adjust __spin_table alignment to match ePAPR v0.94 spec
* loop over all cpus when determing who is up. This fixes an issue if
the "boot cpu" isn't core0. The "boot cpu" will already be in the
cpu_up_mask so there is no harm
* Added some protection in the code to ensure proper behavior. These
changes are explicitly needed but don't hurt:
- Added eieio to ensure the "hot word" of the table is written after
all other table updates have occurred.
- Added isync to ensure we don't prefetch loading of table entries
until we a released
These issues we raised by Dave Liu.

LWMON5 DSPIC POST uses the watch-dog scratch register. So, make
the CFG_DSPIC_TEST_ADDR definition more readable.
Signed-off-by: Yuri Tikhonov <yur@emcraft.com>
Some boards (e.g. lwmon5) need rather a frequent watch-dog
kicking. Since the time it takes for the flush_cache() function
to complete its job depends on the size of data being flushed, one
may encounter watch-dog resets on such boards when, for example,
download big files over ethernet.

Since the current dflush() implementation is know to have some problems
(as seem on lwmon5 ECC init) this patch removes it completely and replaces
it by using clean_dcache_range().
Tested on Katmai with ECC DIMM.

As it seems the "old" ECC initialization routine by using dflush() didn't
write all lines in the dcache back to memory on lwmon5. This could lead
to ECC error upon Linux booting. This patch changes the program_ecc()
routine to now use clean_dcache_range() instead of dflush().
clean_dcache_range() uses dcbst which is exactly what we want in this
case.
Since dflush() is known is cause problems, this routine will be
removed completely and replaced by clean_dcache_range() with an
additional patch.

On ppc405EP and ppc405GP (at least) the ebc is directly attached to the plb
and not to the opb. This patch will try to fixup /plb/ebc if /plb/opb/ebc
doesn't exist.

Currently the timeout waiting for an ARP reply is hard set to 5 seconds.
On i.MX31ADS due to a hardware "strangeness" up to four first IP packets
to the boards get lost, which typically are ARP replies. By configuring
the timeout to a lower value we significantly improve the first network
transfer time on this board. The timeout is specified in milliseconds,
later internally it is converted to deciseconds, because it has to be
converted to hardware ticks, and CFG_HZ ranges from 900 to 27000000 on
different boards.
