++ Say 'Y' here to force the nF bit on. Usually this is set
++ by the bootrom. If it is not set, then the CPU core will
++ run from HCLK instead of FCLK, and performance will suffer.
++ If you see BogoMIPS of about 1/4 of your CPU clock, try
++ turning this on; your performance should double.

++ * acceleration and sleeping are defined by function pointers to OS-specific
++ * code in the struct sdcore. Minimally requires the os_sleep() callback to be
++ * implemented for proper SD card initialization and a pointer to start

++ * callback functions may be left NULL-- they are only to allow speed/CPU

++ *
++ * 3 main public functions - sdreset(), sdread() and sdwrite(). sdreset()

++ * horrible excuses for abstraction, block driver APIs required in other
++ * "modern" operating systems.
++ *
++ * Not all SD cards over the years have followed spec perfectly -- many
++ * don't even check CRC's on the CMD or DAT busses and some have problems
++ * (lock up) when reading/writing the last sectors with SD read/write multiple

++ *
++ * The TS SD hardware cores are not much more than GPIO bit-bang cores with

++ LCD-Linux provides an easy way to drive LCD displays under
++ Linux by creating a character which can be read or written.
++ It features complete VT102 emulation and recognizes
++ many escape sequences. If you want to use it you must also
++ choose an appropriate driver, otherwise it will not be
++ very useful. For more information see
++ http://lcd-linux.sourceforge.net/
++
++ To compile LCD-Linux as a module, choose M here:
