arch: remove blackfin port

2018-03-16T09:55:47Z

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.

Blackfin: Rename IRQ flags handling functions

2010-10-07T13:08:52Z

Rename h/w IRQ flags handling functions to be in line with what is expected for the irq renaming patch. This renames local_*_hw() to hard_local_*() using the following perl command: perl -pi -e 's/local_irq_(restore|enable|disable)_hw/hard_local_irq_\1/ or s/local_irq_save_hw([_a-z]*)[(]flags[)]/flags = hard_local_irq_save\1()/' `find arch/blackfin/ -name "*.[ch]"` and then fixing up asm/irqflags.h manually. Additionally, arch/hard_local_save_flags() and arch/hard_local_irq_save() both return the flags rather than passing it through the argument list. Signed-off-by: David Howells

Blackfin: MPU: handle caches for reserved memory

2010-03-09T05:30:46Z

We weren't handling the user-specified cache behavior for the reserved memory regions (via mem=/max_mem=). The no-MPU code already takes care of this, so add support to the MPU code as well. Signed-off-by: Sonic Zhang Signed-off-by: Mike Frysinger

Blackfin: fix MPU page permission masks overflow when dealing with async memory

2010-03-09T05:30:46Z

Attempting to use the MPU while doing XIP out of parallel flash hooked up to the async memory bus would often result in random crashes as the MPU slowly corrupted memory. The fallout here is that the async banks gain MPU protection from user space too. So any accesses have to go through the mmap() interface rather than just using hardcoded pointers.

Blackfin: MPU: support XIP in async flash memory

2009-12-15T05:15:54Z

The NOMPU code already supported executing in the async banks, so this brings the MPU code in line. Signed-off-by: Barry Song Signed-off-by: Mike Frysinger
