2010-10-29debug_core,x86,blackfin: Clean up hw debug disable APIDongdong Deng
The kgdb_disable_hw_debug() was an architecture specific function for disabling all hardware breakpoints on a per cpu basis when entering the debug core. This patch will remove the weak function kdbg_disable_hw_debug() and change it into a call back which lives with the rest of hw breakpoint call backs in struct kgdb_arch.

2010-10-26m68k{nommu}/blackfin : remove old assembler-only flags bit definitionsPhilippe De Muyter
Long ago, PT_TRACESYS_OFF and friends were introduced as hard defines to avoid straight constants in assembler parts of linux m68k. They are not used anymore, and were not updated to follow changes in linux kernel. Remove them. When similar constants are needed, they are now generated using asm-offsets.c.

2010-10-22Blackfin: merge kernel init memory back into main memory regionSonic Zhang
If the kernel's init section is merged back into the main memory region during boot (which it should since that is how we've laid out the kernel linker map), we want to make sure that these aren't counted as independent regions. Otherwise, if a large mapping is attempted which starts in the init region and extends into the main memory region, the access_ok func will deny it. This leads to weird messages during runtime like "unable to map xxx library" from the ldso but upon running the application again, everything works fine. So if the address of the end of the init region is the same as the start of the main memory region, simply enlarge the memory region to include the init region.

2010-10-22Blackfin: gpio: add peripheral group checksteven miao
Many Blackfin parts group sets of pins into a single functional unit. This means you cannot use different pins within a group for different peripherals. Our resource conflict checking thus far has been limited to individual pins, so if someone tried to grab a different pin from the same group, it would be allowed while silently changing the other pins in the same group. One common example is the pin set PG12 - PG15 on BF51x parts. They may either be used with SPI0 (1st function), or they may be used with PTP/PWM/AMS3 (3rd function). Ideally, we'd like to use PG12 - PG14 for SPI0 while using PG15 with AMS3, but the hardware does not permit this. In the past, the software would allow the pins to be requested this way, but ultimately things like the Blackfin SPI driver would stop working when the hardware rerouted to a different peripheral.

2010-10-22Blackfin: add new cacheflush syscallSonic Zhang
Flushing caches sometimes requires anomaly workarounds which require supervisor-only insns. Normally we don't need to flush caches from userspace so this isn't a problem, but when gcc generates trampolines on the stack, we do. So add a new syscall for gcc to use modeled after the mips version. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-10-22Blackfin: bf548-ezkit: increase u-boot partition sizeMike Frysinger

The predefined i2c address 0x2c doesn't match the configuration of the ad5280 PINs AD0 and AD1 on the tftlcd add-on board.
