Updated SPI code. Added unused SPICARD code.

PXI, IPC and debug code cleanup.

Some PXI code cleanup.

Minor fixes/adjustments to SPI code. Moved spiflash code to ARM11.

Init PXI last and enable interrupts CPU side earlier to prevent hangs.

Use iomemcpy() to copy bootroms and OTP.

Removed AES_subCounter() and replaced AES_addCounter() with optimized version.

Added SHA + NDMA prototype + some notes.

Fixed warning introduced in last commit.

Introducing iomemcpy() and iomemset().

Don't use volatile to prevent reordering.

Corrected OCR register value on SD init to the one from Process9.

Cleanup sdmmc.c/h a bit.

Adjust eMMC clock to be in spec before switching to HS mode.

Set this reg to the same value Process9 does.

Optimize SD card poweron for the lowest possible powerup time.

Fixed bugs in sdmmc_send_command(). Partially implemented high speed mode.

[SDMMC] Enable 4 bit mode after switching and always clear fifo.

Disable SD pullup. Set clock back to 16 MHz since the shitty Lexar SDs don't work with 33 MHz.

Update remaining SDMMC clock comments.

Correct comments in sdmmc.c.

Fixed bootrom/OTP dumping.

Adjust SD init to be in specs.

Remove unneeded reg writes. Set card detect timeout(?) permanently to 0.

Set SD timeout to 0 for faster card detect.

Use higher clocks in MMC driver. Needs careful testing!

Remove bootrom lock code.

Added toggleSuperhax() function.

Merge branch 'master' into lenny

Increase ARM9 TIMER_sleep() accuracy because why not.
