Hi Folks

Been working on getting u-boot's reset command to work correctly on my RPXlite. Kept on getting bus failures around line 181 of cpu/mpc8xx/cpu_init.c (version 1.1.1). I finally tried commenting out the following lines (figuring that I wasn't an 850 and wasn't rev A silicon) and am now able to perform a reset successfully at u-boot's command prompt.

/************************************************************** * The following causes the RPXlite 823 with rev b2(?) silicon * to generate a bus fault when executing u-boot reset command.

/* perform BR0 reset that MPC850 Rev. A can't guarantee * reg = memctl->memc_br0; reg &= BR_PS_MSK; /* Clear everything except Port Size bits * reg |= BR_V; /* then add just the "Bank Valid" bit * memctl->memc_br0 = reg;

***************************************************************/
