1d1f351233 Pios Delay: Add function for measuring time difference between two cycle counts 2011-08-12 04:29:53 -05:00

8b0415d905 bl: alternate stopwatch for small bootloaders 
The small bootloaders (CC and PipX) are out of flash space
so their stopwatch implementation has been swapped out for
one based on the DELAY clock that takes about 500 bytes less
of code space.

Identical functionality is preserved.

df5569c758 Fix a stupid off-by-one that prevented this code from working. 
Update to use 32-bit microsecond values.

Remove PIOS_DELAY_DiffuS per consensus (caller can do it easily themselves).

Update the core delay logic per Stac's suggestion to a version that is
resistant to various overflows.

0df3bb2c37 Restore functions lost due to inept merging, and refactor to take advantage of them. 
Address the following review feedback items:
 - use stdint types
 - avoid the use of magic numbers (define CYCCNTENA)
 - remove expository comment about sneakiness and corresponding code, replace with something simpler based on the API
 - remove commented/#if 0 code

998ab12de4 Delays fixed. 
SD Card fixed and working, tested with 2Gb and 8Gb (SDHC) cards.
Changed startup_stm32f10x_HD.S to work with SysTick_Handler, needs to be changed back for FreeRTOS to work.
