2009-06-12Blackfin: add MDMA defines to make cross-variant coding easierGraf Yang
Add some defines to make the BF538/BF561 look like most other Blackfin parts in that it has a MDMA0 channel available for low level init. Signed-off-by: Graf Yang <graf.yang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-06-12Blackfin: fix detection of cached L2 SRAMMike Frysinger
Make sure our bfin_addr_dcachable() function flags cached L2 SRAM properly else memory easily goes unflushed when working with DMA. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-06-12Blackfin: simplify BF561 coreb driver greatlyMike Frysinger
Since 90% of this driver can be handled in user space, move it to the corebld user space application. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-06-12Blackfin: simplify the do_flush macroMike Frysinger
Simplify the do_flush macro now that we don't need to take into account a second instruction being used together. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Bryan Wu <cooloney@kernel.org>
2009-06-12Blackfin: set bf51x/bf52x to 0.0 rev by default and bf54x to 0.2Mike Frysinger
Update the default revs based on what we actually support (bf54x-0.[01] is too broken to use). Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Bryan Wu <cooloney@kernel.org>
2009-06-12Blackfin: do not error if GPIO IRQ is requested already as GPIOMichael Hennerich

2009-06-12Blackfin: fix warnings with I/O port macrosMike Frysinger
The I/O port functions take ints, so we need to cast them up before passing to our read/write funcs to avoid ugly messes of warnings. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Bryan Wu <cooloney@kernel.org>

2009-06-12Blackfin: fix bug found by traps test case 21Graf Yang
The traps test case 21 "exception 0x3f: l1_instruction_access" would make the kernel panic on BF533's because we end up calling show_stack() infinitely. Signed-off-by: Graf Yang <graf.yang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Bryan Wu <cooloney@kernel.org>
2009-06-12Blackfin: fix data cache flushing when doing icache flushingMike Frysinger
Make sure we flush all data caches and their write buffers before flushing icache, otherwise random edge cases could crop up where stale data is read into icache from external memory. As fallout, punt the combined icache + dcache flush function since we cannot safely do them back to back -- the SSYNC is needed between the dcache flush and the icache flush.

2009-06-12Blackfin: fix link failure due to CONFIG_EXCEPTION_L1_SCRATCHGraf Yang

2009-06-12[S390] maccess: arch specific probe_kernel_write() implementationHeiko Carstens
Add an s390 specific probe_kernel_write() function which allows to write to the kernel text segment even if write protection is enabled. This is implemented using the lra (load real address) and stura (store using real address) instructions.

2009-06-12[S390] profile_tick called twiceMartin Schwidefsky
profile_tick is called twice for every clock comparator interrupt. The generic clock event code does it in tick_sched_timer and the s390 backend code in clock_comparator_work. That is one too many, remove the one in the arch backend code. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2009-06-12[S390] vmalloc: add vmalloc kernel parameter supportHeiko Carstens
With the kernel parameter 'vmalloc=<size>' the size of the vmalloc area can be specified. This can be used to increase or decrease the size of the area. Works in the same way as on some other architectures. This can be useful for features which make excessive use of vmalloc and wouldn't work otherwise. The default sizes remain unchanged: 96MB for 31 bit kernels and 1GB for 64 bit kernels.

2009-06-12[S390] add mini sclp driverHeiko Carstens
This adds a mini sclp device driver for very early use. The primary and probably only use will be to emit a message to the console if the cpu doesn't provide the minimum required capabilities to run the kernel. After printing the message a disabled wait will be loaded and the machine stops operating. Printing the message is also part of this patch.

2009-06-12[S390] vdso: kernel parameter syntaxMartin Schwidefsky
The syntax of the vdso kernel parameter is documented as vdso=[on|off]. The implementation uses vdso=[0|1], an invalid parameter string disables the vdso support. Fix the mismatch by adding vdso=[on|off] as additional parameter syntax. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2009-06-12x86: Provide _sdata in the vmlinux.lds.S fileCatalin Marinas

On a system where system memory (according e820) is not covered by mtrr, mtrr_trim_memory converts a portion of memory to reserved, but bootloader has already put the initrd in that range.
