This directory contains sample code for autonomous boot:

   L1 code resides in EEPROM and
   L2 code in UVEPROM at a fixed PCI address


1. For more details, please see the section on "Bootstrapping
   TriMedia in Autonomous Mode" in Part 3 of the CookBook.


2. There are two makefiles in this directory -

     makefile.unix - for making l1.mi and l1.eeprom on Sun and HP.

     makefile.win  - for making l1.mi and l1.eeprom on Windows
                     using the MKS Make facility.


3. The macros SDRAM_BASE and SDRAM_LIMIT can be modified to suit
   any customized TriMedia board design.

   To modify the macros, simply use a text editor and change the
   SDRAM_BASE value to match your board's SDRAM base address and
   the SDRAM_LIMIT value to the value of SDRAM_BASE plus the
   board's SDRAM memory size.

   NOTE: SDRAM_LIMIT should contain an address value that is
         just one byte beyond the highest SDRAM address.

         For example, if the SDRAM_BASE is 0xfe000000 and there
         are 4 mega bytes of SDRAM, then SDRAM_LIMIT should be
         set to  0xfe400000.
