Those are the recommended maximal timeouts in §4.6.2
Despite that, some people still experiment problems with the SD driver since MMU and data cache were enabled

- 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)

Inline the 2 uses, and use a preprocessor sanity check for identification frequency

Fixes various storage related problems like stuttering audio, md5sum and test disk failure and Sansa Fuze's backdrop corruption by using aligned buffers. There's a speed penalty but stability has more priority.

the AMS sansas, which solves the ">2GB problem" (the problem that we could not
access data past 1GB on devices having more than 2GB internal storage).

Retry blocks transfer if a problem happened
Remove unneeded blocking API from DMA code

Add dma_retain() and dma_release() to reference count the users

* Adds a callback to be called on end of transfer
* Add a function to disable a channel
* Services the 2 channels if both are active in the isr

Reorder system_init() to initialize peripherals not only in bootloader
Use a 65MHz PCLK (and memclk) which will be needed for realtime decoding

- Make write_sectors() function fail.
- Disable interrupts while transferring data and do not yield(), so we are sure the FIFO is not overflowed
Note this solution is only temporary since it's not friendly to other threads and confuse kernel tick precision
This will be reverted when we will be using DMA to access the SD card, but for now it permits further development
- PL180: Rename the MMC_* registers into MCI_*, to not make people believe it is a MMC only controller
- Supports non aligned destination buffers when reading
- Correct the timeout units which were lamely copied from ata-sd-pp.c and were in milliseconds (note that the timeouts are disabled now)
- Higher a bit the stack size
- Use the full initialization procedure in the bootloader and the loaded firmware
- Use the CCU_IO register only when a SD slot is present
- Put some panicf() around to catch problems

Implement some of the new functions
Use as3514 rtc
Add AS3525 case in rolo.c
Copy card_get_info_target() from ata-sd-pp.c , and use the correct 32bits words order

Adds read-only SD driver, largely copied from ata-sd-pp.c
Only tested on the embedded SD, on the Clip
First steps to build a Normal firmware

Don't reset the peripherals
Don't mind about the spare register
Don't mind about MEMSTICK peripheral
Use correct clock speeds for IDE
Tested on Clip only

Rewrite a new header distributed under GPLv2 or later, and place it in
