Description: embed-it dpu
============================================================================
CPU: MCF52259, ??MHz
SRAM: 64K
FLASH: 512K

This is a embed-it board that uses the MCF52258 Coldfire CPU. 
This board is running at ??MHz scaled from the internal relocation 8MHz oscillator.



OLD-STUFF from MCF52235 EVB ... we have to change it ...
============================================================================
NOTES:

Currently this BSP must be configured with most RTEMS features turned
off as RAM usage is too high.

Configure as follows:
configure --target=m68k-rtems4.9 --enable-rtemsbsp=mcf52235 \
          --disable-networking --disable-posix --disable-itron --disable-cxx \
          --disable-tests

To get the tests to compile (but not run) change the linkcmds to specify
a larger sram memory region (256K works).  This of course will let you 
compile all tests, but many or most of them wont run.

See testsuites/samples/minumum for an example of what type of config flags
you need for this BSP!

In you project before you include confdefs.h, define some or all of the
following:

#define CONFIGURE_DISABLE_CLASSIC_API_NOTEPADS
#define CONFIGURE_DISABLE_CLASSIC_NOTEPADS
#define CONFIGURE_INIT_TASK_STACK_SIZE x
#define CONFIGURE_MINIMUM_TASK_STACK_SIZE x
#define CONFIGURE_INTERRUPT_STACK_SIZE x

Note that the default stack size is 1K
Note that the default number of priorities is 15

============================================================================
TODO:

*) Add drivers for I2C, ADC, FEC
*) Support for LWIP
*) Update the coverhd.h (calling overheads) page 21 of the BSP guide
*) Recover the 1K stack space reserved in linkcmds used for board startup.
