d1faf8b39c FS#10317 - Sansa AMS 32-bit timers. Configure the timers for 32-bit mode instead of the default 16-bit mode.

426cdb1284 Commit FS#10285 - Sansa Clip alternative button driver. This driver alternates one row in the button matrix per kernel tick, avoiding the need for explicit delays between selecting a button row and reading colums.

f504153857 FS#10048 : enable MMU and data cache on Sansa AMS to give a major speed up 
- cache IRAM and DRAM
- map IRAM just next to DRAM to remove the need for -mlong-calls and reduce binsize
- tweak delays in Fuze button code
- tweak delays in Clip button code (down button sometimes doesn't respond anyway : an alternate driver is being worked on)

Before reporting any problem, please check your filesystem or format your player from the OF

2409c28f21 Sansa AMS: Revert r21177 : the timer frequency is used by the user timer (example: metronome will be twice too fast)

Comment that call_tick_tasks() will read the scrollwheel
Remove the unneeded volatile type qualifier from poll_scrollwheel

*Correct/update some comments
*Make BUTTON_REPEAT generation more relable (do it like the e200v2, but with a shorter repeat intervall)
*adjust button_delay
*remove unecessary wait for fifo empty (no lcd function returns with fifo not empty)

adb978a44d Sansa AMS: Various fixes/enhancements for clock frequencies 
Fix CGU_DBOP setting

Set PCLK to the exact frequency (62MHz, not the maximal frequency)

Use a better comment for CLK_DIV macro

Use preprocessor safety checks for clock divider sizes to avoid future mistakes (not for SD_IDENT frequency since that check is handled by mci_set_clock_divider)

Use maximal IDE frequency of 66MHz (like OF), not 90MHz like written in AS3525 datasheet. The IDE chip is somehow linked to internal storage, and a too high frequency could affect the storage driver.

Use the same DBOP frequency of 32MHz for all models (like OF, verified clip, fuze, e200v2 and m200v4), compromise between performance and battery life could be added in the future for each target
Performance increase on Sansa Fuze with DBOP freq. set to 64MHz: +12% fps for lcd_update, +1% fps for yuv

Thanks to daytona955 on the forums for his help
