Angus Gratton 9faf9c9416 newlib locks: Fix _lock_init() & _lock_init_recursive() failing to initialise a lock 
If scheduler was running, and lock was an auto variable initialised at runtime by _lock_init*, initialisation could fail
if the lock variable held non-zero stack memory (and lock would be left invalid).

In other cases the lock is statically initialised to zero by __LOCK_INIT*

Angus Gratton 6fa47125b5 freertos: Fix crash when waking task on CPU1 with scheduler disabled 
xPendingReadyList[1] was never initialised correctly, so if a task is added to this list (ie by xSemaphoreGiveFromISR()
or similar) while scheduler is disabled, then it causes a null pointer dereference.

Bug produces stack traces similar to:

Wangjialin 2fbc62f986 feature(psram): add 80Mhz mode for psram. Since we have flash rom code patch now, we can fix the compatibility issue between SPI APIs and psram. 
1. add qio enable option in bootloader for GD25LQ32C flash.
2. add option for psram mode: 40m+40m, 80m+40m, 80m+80m.
3. fix bugs in spi_flash_rom_patch

Jeroen Domburg 671787a966 After rebasing, it was found out that flushing the cache drops the writeback-pending psram cache lines on the ground. We now evict these by reading 64/128K of memory before flushing the cache. Also fixes a snafu in psram cache mode (inverted hi/lo and even/odd selectors) as well as an option to not let the heap allocator touch the psram. 2017-05-16 13:11:59 +08:00
