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.

Introduce a new .init section for initialisation code, so that it can be copied to an area which is later overwritten before calling. The stack/bss can then overwrite that code, effectively freeing the code size that the initialisation routines need. Gives a few kB ram usage back.
Only implemented for PP and as3525 so far. More targets could be added, as well as more functions.

SD_ALL_SEND_CID was using cardinfo.cid to store the response instead of the temp array used for long responses.

Compilation shows a warning for the first argument of the lcd_bitmap() call in show_logo().

Remove MCI_HCON read from init_controller() as it now appears unneccesary.
Make sd-init_card() use similar init sequence to the one in sd-as3525.

I've left in some commented out code for now as this is still a bit experimental.....

Differences remaining:
- list of peripherals reset
- CGU_PROC isn't modified on as3525v2
- CGU_PLLA bits aren't known, but we use a known setting for 240MHz

Do not use a static variable for buttons, else they're never reset
Remove unneeded code
Move GPIO_DIR setting to init function
git-svn-id: svn://svn.rockbox.org/rockbox/trunk@24855 a1c6a512-1295-4272-9138-f99709370657
check all error bits
only signal wakeup on data transfers, not on commands
trim down send_cmd
git-svn-id: svn://svn.rockbox.org/rockbox/trunk@24851 a1c6a512-1295-4272-9138-f99709370657
not touching MCI_CTYPE (leaving bus width to 1) gives data transfers
ignore the hardware locked up while error bit for now
remove printf() helper & debug code

Disable errors on response timeout since it can happen on SD_SEND_IF_COND
Disable errors on start bit error : it's ignored by the linux driver
No panic on my side with those 2 bits unchecked, but no transfer
completion either.
Note: the Linux driver doesn't implement DMA

Reset DMA before transfers and check data transfer over bit in isr
Still no error or data transfer over conditions
Read the correct status register in isr : there is a masked interrupt
status register and a general status register

Initial button driver for clip+. I've followed the steps the OF uses to read the buttons.
There is no hold button on the clip+ so for now calling button_hold() siply returns false.
The OF actually sets an additional flag for the 2nd read from D6 and not BUTTON_POWER as I have done here.

The code assumed LCD pixels were packed on 16 bits values but for the
Clip we use 8 bits values.
