* Blackfin: replace harcoded define with proper THREAD_SIZE macroBarry Song2010-03-091-1/+1

* Blackfin: fix relocation errors with large initramfs imagesJie Zhang2010-03-091-5/+8
| | | | | | | | | | | | Since we are now discarding .exit.text at runtime instead of link time, we need to place all .text sections ahead of the .data sections. Otherwise, a really large attached initramfs may cause link errors as it pushes the PC relative relocations behind the limits of the Blackfin ISA (~16meg). The instructions in the .exit.text are unable to call back into the .text sections leading to a link failure.

* Blackfin: SMP: make core timers per-cpu clock events for HRTYi Li2010-03-097-123/+146
| | | | | | | | | | | | | | | SMP systems require per-cpu local clock event devices in order to enable HRT support. One a BF561, we can use local core timer for this purpose. Originally, there was one global core-timer clock event device set up for core A. To accomplish this feat, we need to split the gptimer0/core timer logic so that each is a standalone clock event. There is no requirement that we only have one clock event source anyways. Once we have this, we just define per-cpu clock event devices for each local core timer.

* Blackfin: fix MPU page permission masks overflow when dealing with async memoryBarry Song2010-03-093-11/+38
| | | | | | | | | | | | | 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.

This patch creates the device_lock/unlock/trylock() functions, and converts all in-tree users to them.
