用于TM1300/PNX1300系列DSP（主要用于视频处理）的flash文件系统的程序源码。

This directory contains a number of sample flash drivers for use with the
TriMedia flash file system manager. A user has various options when it comes 
to using the Flash File System drivers. A user can use the BSP, or flash 
specific driver.

It is STRONGLY recommended that users use the BSP as the Flash driver, and
only use the specific Flash Drivers for boot purposes.

A user can use the BSP for all Flash File System operations. However if a 
user wishes to boot by reading from Flash, the boot code must be 2K or less. 
In this case the BSP will not be small enough to use, so a Flash driver will 
be required. If the Flash driver is only used for booting, then the following 
function must be defined :-

FLASH_read()
FLASH_block_read()

The Flash driver must also declare and initialize the following variables :-

Int     SZOF_FLASH_BLOCK;
Int     NROF_FLASH_BLOCKS;


A user can either use a flash driver for all Flash File System operations. 
In this cace, at the very least the flash driver must write the following
functions :-

FLASH_init()
FLASH_read()
FLASH_write()
FLASH_block_erase()
FLASH_block_read()
FLASH_block_write()

The Flash driver must also declare and initialize the following variables :-
Int     SZOF_FLASH_BLOCK;
Int     NROF_FLASH_BLOCKS;
