Now making the Fuzev2 bootloader build should be pretty easy
TODO:
- write button driver (FlynDice found all buttons already)
- find button light
- decide if lcd-ssd1303.c must be modified for Clip+ using SSP or forked
- check if backlight code works (I copied Clipv2 code)

Voltage scaling seems to be causing various problems mostly related to issues with the uSD cards.
The increased runtime benefit only amounts to ~30 minutes as currently implemented so it seems prudent to disable it once again at this time.
We still don't understand why the core voltage being lowered would impact the uSD card but in fact it does. The internal cards do not seem to have problems.
I have simply #ifdef'd the voltage scaling code with HAVE_ADJUSTABLE_CPU_VOLTAGE so if you want to use voltage scaling simply define that and the voltage scaling code should run.

Reuse some code from Clip (LCD) and a lot of code from AS3525
Add a new CPU type : AS3525v2, identical to AS3525 except it's an ARMv5 (arm926-ejs)
SD code still not working
For an unknown reason LCD doesn't work anymore (to be investigated)

If a panicf() is called while a button is still pressed, the Sansa would
reboot immediately with no chance to see the message

INT_GPIOB is not used
INT_MCI0 and INT_GPIOA are only put in the table if needed

Still disabled on all targets:
- Fuze and e200v2 see spurious interrupts with no source defined
- Clip/m200v4 deadlock instantly when starting recording (perhaps due to low memory size)
Having the code in SVN will make working on this feature easier
Also add keymaps for Fuze, and correct Frequency section of recording
options : the 22.05kHz limitation of e200v1 and c200v1 doesn't apply to
Sansa AMS (different I2S hardware, unrelated to as3514)

Reimplement voltage scaling on AMS Sansas at 1.10v during unboosted operation to improve runtimes. The voltage is now also boosted during disk access if a µSD is present. This prevents the µSD problems we saw on the last implementation.

They would previously appear like coming from the (disabled) watchdog
module

The input to the ADC is now set to CVDD inside the while loop. If the input gets changed while waiting for the voltage to be read it will now be reset to CVDD before the next read is attempted.

Lower CVDD core voltage to 1.10 volts when the frequency is less than 200 MHz.

- 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

Reorder system_init() to initialize peripherals not only in bootloader
Use a 65MHz PCLK (and memclk) which will be needed for realtime decoding
git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19330 a1c6a512-1295-4272-9138-f99709370657
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
git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19276 a1c6a512-1295-4272-9138-f99709370657
Use a 24MHz peripheral clock instead of 64MHz for battery life
git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19234 a1c6a512-1295-4272-9138-f99709370657
A button press of ~10s will trigger the hardware power off instead of ~1s

The AMS Sansa use the same AS3514 registers (except USB_UTIL which was added)
Use the register defines in AMS Sansa code instead of hardcoded values
git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19073 a1c6a512-1295-4272-9138-f99709370657
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
git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19064 a1c6a512-1295-4272-9138-f99709370657
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

init_threads() requires that they are disabled when called
anyway they are not needed at the moment, so leave them disabled

The AS3525 SoC ships with an ARM PL172 MPMC controller
Also correct the memory sizes in tools/configure
