The DMA base registers are available in a global named "base_addr" for every Blackfin variant. Give this a more descriptive name, and remove duplicate tables from some drivers. Signed-off-by:

theres no need to declare ram{end,start,base} in the head.S files when declaring them with the other memory related variables in setup.c is so much simpler/nicer Signed-off-by: -

Previously, init failed to do anything meaningful; it turns out that the reason is that FD-PIC has a readonly data section which can be located in the XIP filesystem, and various address checks in the kernel reject such addresses for syscall arguments. Hence, init's execve ("/bin/sh", ...) failed with error code EFAULT. There's room for improvement here: in case people want to have filesystems on flash rather than in main memory, _access_ok should be modified to allow this. This bug fix is also dedicated to Michael Hennerich. Signed-off-by: -

The function flush_switched_dcplbs was clearing the CPLB entries covering the process permission bitmasks. This means that the sequence flush_switched_dcplbs (); set_mask_dcplbs(mm->context.page_rwx_mask); has a problem: if kernel code (such as an interrupt) causes a CPLB miss before set_mask_dcplbs completes, the CPLB handler function causes a double fault, with an instantaneous reboot. This bug fix is dedicated to Michael Hennerich, the only person in the world capable of providing working JTAG hardware. Signed-off-by: -

This is a rather old performance improvement for the signal handling code, which was originally only committed on the 2007R1 branch as a workaround for what we suspected to be a hardware bug. There's no point in constructing a sigreturn stub on the stack and flushing caches; we can just make signal handlers return to a known location in the fixed code area. Signed-off-by:

[Blackfin] arch: relocate MAX_SWITCH_{D,I}_CPLBS from the header to the file where it actually gets used. relocate MAX_SWITCH_{D,I}_CPLBS from the header to the file where it actually gets used. this way when we change CONFIG_MEM_SIZE in our kconfig, we only rebuild one or two files rather than a whole bunch that implicitly include cplb.h. this will also remove the ability to clear the swapcount on the fly, but i really dont think that functionality is important. ultimate goal is for CONFIG_MEM_SIZE to go away and calculate this value on the fly based on what u-boot programmed for us.

replace implied numbers with real values so that strace is able to calculate things automatically ... the numbers are frozen in our ABI, so having them based off other __NR_xxx values really doesnt matter -- no functional changes Signed-off-by:

Bug: CONFIG_MPU doesn't seem to handle access to ASYNC/IO Memory well http://blackfin.uclinux.org/gf/project/uclinux-dist/tracker/?action=TrackerItemEdit&tracker_item_id=3912Signed-off-by:

There were a couple of problems with the way the trace buffer state is saved/restored in assembly. The DEBUG_HWTRACE_SAVE/RESTORE macros save a value to the stack, which is not immediately obvious; the CPLB exception code needed changes to load the correct value of the stack pointer. The other problem is that the SAVE/RESTORE macros weren't pushing and popping the value downwards on the stack, but rather moving it _upwards_, which is of course completely broken. We also need to make sure there's a matching DEBUG_HWTRACE_RESTORE in the error case of the CPLB handler. Signed-off-by:
