e2f165c088 Sansa AMS: make the UNCACHED_ADDR macro work for any type of pointer, and only use pointers with it, not arrays

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

45711ac286 Sansa AMS: centralize clock settings in clock-target.h
Reorder system_init() to initialize peripherals not only in bootloader
Use a 65MHz PCLK (and memclk) which will be needed for realtime decoding

0b6d65b09e Sansa AMS: Use a valid PLL setting (248MHz aka maximum fclk)
Fix lcd drivers which stopped working after changing the PLL.
Move set_cpu_frequency() to a place where it is actually used.
Remove enable_irq() call already done by the bootloader

97e907538a Sansa AMS: implement set_cpu_frequency()
Use a 24MHz peripheral clock instead of 64MHz for battery life
