More code improvements/documentation.

Improved RSA code a bit. Now uses interrupts.

A few code optimizations.

Updated SPI code. Added unused SPICARD code.

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

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

Added SHA + NDMA prototype + some notes.

Introducing iomemcpy() and iomemset().

Forgot this define.

Cleanup sdmmc.c/h a bit.

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

Use higher clocks in MMC driver. Needs careful testing!

Timers: Use integer math on ARM9 and faster fp math on ARM11.

Updated NDMA documentation.

Minor build system stuff.

Optimized AES code and fixed a bug which prevented very large FIRMs from beeing properly decrypted from NAND.

Added function to read internal SHA engine state. Optimized SHA_update().

Reverted C++ header commit because it looks ugly. We will change this later.

Don't hardcode header location in firm_size().

Add missing C++ guards for C code.

Introducing cfg9.h and cfg11.h.

Move most inline asm to arm.h.

Introducing arm.h.

Use volatile instead of __volatile__.

Improved RSA code a bit.

Return current number of ticks on timer stop.

arm9: remove nandimage dead code

hardware.c --> system.c. Call systemInit() before main().

Remove hardwareDeinit() on ARM9 since it is not needed anymore.

Fixed the race properly on ARM11.
