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.

sched/headers: Prepare for new header dependencies before moving code to

2017-03-02T07:42:34+00:00

We are going to split out of , which will have to be picked up from other headers and a couple of .c files. Create a trivial placeholder file that just maps to to make this patch obviously correct and bisectable. Include the new header in the files that are going to need it.

early_printk: consolidate random copies of identical code

2013-04-30T01:28:13+00:00

The early console implementations are the same all over the place. Move the print function to kernel/printk and get rid of the copies.

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: catch hardware errors earlier during booting

2009-09-17T01:31:44+00:00

Allow hardware errors to be caught during early portions of booting, and leave something in the shadow console that people can use to debug their system with (to be printed out by the bootloader on next reset). This enables the hardare error interrupts in head.S, allowing us to find hardware errors when they happen (well, as much as you can with a hardware error) and prints out the trace if it is enabled. This will catch errors (like booting the wrong image on a 533) which previously resulted in a infinite loop/hang, as well as random hardware errors before before setup_arch(). To disable this debug only feature - turn off EARLY_PRINTK. Signed-off-by: Robin Getz Signed-off-by: Mike Frysinger

Blackfin: do not configure the UART early if on wrong processor

2009-06-13T11:20:10+00:00

Before we configure the early UART, check to make sure we are running on the expected processor - otherwise, we cause problems by configuring pins that don't exist (and causing an infinite loop of faults). Signed-off-by: Robin Getz Signed-off-by: Mike Frysinger

Blackfin: convert early_printk EVT init to a loop

2009-06-12T10:12:01+00:00

The EVT registers are all contiguous in the memory map, so using a loop to initialize them all rather than hardcoding the list results in much better generated code (a hardware loop rather than a whole bunch of individual loads). Signed-off-by: Mike Frysinger
