arch: remove blackfin port

2018-03-16T09:55:47+00:00

The Analog Devices Blackfin port was added in 2007 and was rather
active for a while, but all work on it has come to a standstill
over time, as Analog have changed their product line-up.

Aaron Wu confirmed that the architecture port is no longer relevant,
and multiple people suggested removing blackfin independently because
of some of its oddities like a non-working SMP port, and the amount of
duplication between the chip variants, which cause extra work when
doing cross-architecture changes.

move idle task point to percpu blackfin_cpudata and add smp_timer_broadcast
interface.
enable SUPPLE_1_WAKEUP and add BFIN_IPI_TIMER ipi support.

Blackfin: SMP: drop unused blackfin_cpudata.idle pointer

2011-05-25T12:13:42+00:00

Not sure when we stopped using this field, but nothing in the tree uses
this now, so punt it.

Blackfin: rewrite resync_core_{i,d}cache() SMP logic to avoid per_cpu data

2010-03-09T05:30:50+00:00

This functions are implicitly called by core functions like cpu_relax(),
and since those functions may be called early on before common code has
initialized the per-cpu data area, we need to tweak the stats gathering.
Now the statistics are maintained in common bss which makes these funcs
safe to use as soon as the C runtime env is setup.

Blackfin: mass clean up of copyright/licensing info

2009-10-07T08:36:26+00:00

Bill Gatliff & David Brownell pointed out we were missing some
copyrights, and licensing terms in some of the files in
./arch/blackfin, so this fixes things, and cleans them up.

It also removes:
 - verbose GPL text(refer to the top level ./COPYING file)
 - file names (you are looking at the file)
 - bug url (it's in the ./MAINTAINERS file)
 - "or later" on GPL-2, when we did not have that right

It also allows some Blackfin-specific assembly files to be under a BSD
like license (for people to use them outside of Linux).

Blackfin: drop per-cpu loops_per_jiffy tracking

2009-07-16T05:52:44+00:00

On Blackfin SMP, a per-cpu loops_per_jiffy is pointless since both cores
always run at the same CCLK.  In addition, the current implementation has
flaws since the main consumer for loops_per_jiffy (asm/delay.h) uses the
global kernel loops_per_jiffy and not the per_cpu one.  So punt all of the
per-cpu handling and go back to the global shared one.

Blackfin: add blackfin_invalidate_entire_icache for SMP systems

2009-06-13T11:20:07+00:00

The KGDB code uses this when switching processors to make sure the icache
is in a valid state.
