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.

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

Merge branch 'master' into lenny

Typo fixes/consistency.

[ARM9] Cache code optimizations.

Updated NDMA documentation.

Introducing superhax.

Fixed ARM9 panic/exception/assert not displaying anything on screen.

Renamed members of _uX types.

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

Added typedefs for >64 bit types to types.h.

Use sizeof() instead of hardcoding the increment of data in SHA_update().

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