f5db6b9ce3 Sansa AMS : higher a bit the delay between acmd41 loops, needed for some microsd cards. FS#10268 by Eric Shattow

9067c915ad Use I2C2_DACNT register (number of pending i2c bytes to read/write) to determine if an ascodec i2c transfer is done. This should fix i2c problems with MMU enabled.

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

bac611868e FS#10114 - Sansa AMS : use IRAM for codecs on >2MB targets Rafaël Carré 
Activates IRAM for AMS Sansas to be used by codecs and core. Fixes Reboot-on-mp3 and gives speed up on codecs using IRAM in general.
I've made a change: the core/codec ratio is 0x20000/0x30000 instead of 0x10000/0x40000, 0x30000 is way more than codecs currently use (0x14000 at max) and the core might need more than 0x10000.

4ed387d603 Fix reds and yellows (hopefully). Some targets apparently didn't properly #ifdef lcd_enable and lcd_sleep code out, so that it got partly active in the bootloader; rename the ui simulator stub fixes most reds; for the clip: move the hook code into lcd-1bit-vert.c which should fix the bootloader red.

b7739fbf1c Rework lcd_enabled and lcd_set/call_enable hook 
a) lcd_enabled() is now lcd_active(), and is available for HAVE_LCD_SLEEP only targets (e.g. ipod video) too. It was depandent on HAVE_LCD_ENALE only before
b) rename the hook accordingly, and implement the hook for other other targets too (e.g. the clip [the only mono target with lcd_enable/lcd_sleep yet, so the code is still in the lcd driver], ipod, fuze, c200)
