The new controller framebuffer (different from what is in clipv1/clipv2 and some clip+) has 128 columns, the old has 132 columns and is centered on the screen.

There was a stupid bug in endpoint listing which caused random cancelling of EP0 transfers. The new scheme to handle EP0 transfers should avoid an unexpected setup packet which might cause a deadlock or confuse the core.
There is still an issue with the cancel_transfers function is still.

There is still a problem after the set address request which makes the driver working randomly.
I still didn't manage do get a proper disconnect interrupt.
From time to time, when unplugging cable, neither rockbox nor usb driver reports disconnect even.

On tx underruns, a write is aborted early, leaving the dma channel active.
We didn't explicitly disable it, so there were still 4 words in the dma
controller fifo, corrupting the retried write.
To chase this bug I added verify after write, if no one sees write errors in
the next week or so this can be removed.

We always need to write MCI_ARGUMENT register so if the command expects
no argument just set the function argument to 0
Code is now similar to as3525v2
hint: merging the 2 and/or all the SD drivers would be nice

Maybe it's not possible to change NAK while the DMA engine is active.
Burst probably can't hurt.

test_disk says everything is alright but playback is buggy, especially
when playing lossless files
git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27044 a1c6a512-1295-4272-9138-f99709370657
This caused mounting of µSD to fail on Fuzev2 in some cases, although
the card is detected properly
This might be the cause of playback glitches (more frequent for lossless
files) on clipv2
Trying to set the main PLL at 384MHz and FCLK at 240MHz didn't work, so
there might be some problems not understood yet

- cpufreq is now the same than AMSv1
- audio playback frequency should be more accurate
- adjust pclk (24.8MHz on clipv2/clip+, 41.333..MHz on fuzev2) : it is
still lower than the AMSv1 which use 62MHz on every model

We can't pop into pc on ARMv4t when using thumb: the T bit won't be
modified if we are returning to a thumb function
Code running on ARMv4t should use the new ldrpc / ldmpc macros instead
of ldr pc, [sp], #4 and ldm(cond) sp!, {regs, pc}

This lead to freezes under various conditons (bug report: FS#11267)
Battery life is almost not (if at all) affected:
- between 4 and 8 minutes less runtime for fuzev1
- 9 minutes less runtime for c200v2 (2 minutes difference on a 2 hours run)
Additional verifications of the runtime (including on other models) wouldn't hurt

this removes workaround for spurious interrupts added in r26316
side effect: make keyclicks work correctly when used intensively (with
the scrollwheel for example), the clicks should be inserted fast enough
for the PCM fifo to not become empty.
PL190 can cause spurious interrupts if an interrupt is triggered by a
peripheral shortly before the interrupt for this peripheral is cleared
from VIC registers.
As an effect we should only write in VIC_INT_EN_CLEAR after having
disabled the source of the interrupt in the peripheral.
