The main reason for having -a separate bootloader for PreP compliant firmware is that the -initial code is relocated by firmware at an unknow address -(actually 0x5000 on motorola MCP750) and that as Gabriel I -think having a relocatable bootloder code is a must. - -So the way of building a binary executable that can be booted via -hard disk or network boot goes like this : - - - make a RTEMS executable, - - put is as data section in the bootloder binary, - - relink the loader (see make-exe macros for details), - -I would like to thank Gabriel for his support and his code. -The original code can be found in form of a patch to official linux -kernel at (I insist not vger ppc kernel or Imac ppc kernels!!) : - -<ftp://vlab1.iram.es/pub/linux-2.2/> - -After applying the patch, the code is located in a new directory -called prepboot. - -(NB : note use ftp not netscape...) - -Note that the actual code differs a lot since Gabriel choose to use -a CHRP compliant mapping instead of a Prep Mapping to save -BATs. I had no time to upgrade the code to its new one allthough -I agree it should be done... - -I have also splitted the original code to have a more modular -design enabling to reuse code between the loader and RTEMS -initialization (e.g printk, ...). - -Eric Valette (valette@crf.canon.fr) - - -************************************************** -2003/5/7, Greg Menke, gregory.menke@gsfc.nasa.gov - -Reworked the pci bus 0 initialization a little and added support for -configuring an arbitrary number of other busses & their respective -bridges. Also added support for configuring IO ranges below 0x10000, -which I think is reasonable given this is a PowerPC bsp. - |
