Fixed the bootrom/OTP dumping issue properly.

Corrected a few small bugs/cleanup.

Port back changes from open_agb_firm. Now with proper screen init.

Hardware code cleanup + new documentaion/findings.

Use udf pseudo instruction to trap unused exception vectors.

Don't disable vfp (no harm in leaving it on). Lots of small, mostly style changes.

Added GPU reset code (unused because it works as is). Disabled tag RAM and L1 parity checking on ARM11. Don't rely on code overhead at SD card init for the 74 clock pulses. Implemented new cycle accurate delay function.

More code improvements/documentation.

Improved RSA code a bit. Now uses interrupts.

A few code optimizations.

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.
