Before the clock settings were fixed this setting actually caused the problem it now seems to solve.
Random freezups seem to be gone for clip+ at least.

We only use DMA transfers so we should not need to change/reset the FIFO configuration.
Also add comment showing what we set as the TX/RX watermarks.

XPD was being switched between SD-MMC interface and general i/o functions in the sd_enable() function similar to as3525v1.
Since the as3525v2's do not seem to use XPD as general i/o there's no need to switch it back.

It is equally fast and doesn't need an additional mask
Thanks to amiconn for pointing to it

PCLK doesn't use PLLA as a source but FCLK, so when changing FCLK with
CGU_PROC register, we must change PCLK as well with CGU_PERI register
Operate with 24MHz PCLK (and unboosted FCLK) for Clipv2/Clip+
Use 60MHz on Fuzev2 to keep the display fast enough (still slower than
Fuzev1 though)
µSD seems to function correctly now

We can write to DBOP_DOUT in 8 bits mode : bits 7..0 are mapped to the
LCD, not bits 15..12 and 3..0 like on Clipv1

1 more hour of battery life measured on Clip+ : 16h30 with mp3 @192kbps
Fuzev2 frequency isn't changed because the scrollwheel is less
responsive below 60MHz

Brightness changes on the Fuzev2 now work flawlessly
This might also explain why my Clip+ would sometimes "not boot", that
could have been because the backlight was not enabled at all.

Move scrollwheel parsing function into separate file as it's reused.

the arm926-ejs doesn't have synchronous/asynchronous/fastbus modes, so
just change CGU_PROC directly
Note: we could use a lower unboosted frequency now

Instead of modifying CGU_PROC to get 24MHz pclk, just switch to fastbus else Clip+ wouldn't boot
Tested on fuzev1/Clip+

They're all the same when charger is unplugged, but when it's plugged:
- BVDD is way too high
- RTCSUP oscillates between 2 values
- CHG_IN acts like RTCSUP on some models but seems to works fine on my Clip+

I have also made the CMD_CHECK_CRC_BIT unused for now since we do not check any response crc values yet.

The controller only needs to be reset if we had an error to clean up any leftover trash...
Move comment pertaining to retry variable so it's actually nearby.

Adjust the initial MCI_MASK value to also mask the MCI_INT_RXDR and MCI_INT_TXDR bits as it seems we don't use them for dma transfers.

Move CLKDIV macros into clock-target.h.
Only enable the necessary interfaces for the 3 clock registers used for SD.
Add MEMSTICK and SDSLOT registers to bottom of register display in View HW info debug page.

The registers value does not change so we don't need to read them
This avoids dividing by 0

We don't need the post transfer call this way. We check on TRAN state before each partial transfer.

as3525 comes with a as3517, as3525v2 with a as3543, rename specific
registers accordingly
Existing problems: FM (line out) doesn't work, volume can't go below a
certain point

We do not need a stack pointer at this step, and we are sure to not use
memory not initialized yet (like bss)
Fixes FS#11114 (tested on Fuze)

- buttonlight works
- backlight turns on (quite weak though and no brightness adjustment/backlight off functional)
- don't share drivers with e200v2/fuzev1 for now as it's not entirely clear how dbop plays into this
- deactivte scrollwheel as it's messing up the timer setup in kernel-as3525.c indicating the dbop input reading doesn't work well
- still no working bootloader/no lcd or buttons

Especially when using caches we might read the response too fast and get
the response for the previous command instead.
Now Clip+ boots fine with both instruction & data caches enabled, the
delay might need to be lowered though: boot time is a bit longer.

calc_freq(CLK_PLLA) for as3525v2 simply returns 240MHz instead of calculating until we understand how it is calculated.
Now displays 922T or 926ejs depending on version.
Remove SD and uSD info from as3525v2 as it is not useful due to different SD controller.
Increased the lines used for each page of display on clip screen size.
