powerpc/booke: Introduce new CONFIG options for advanced debug registers From: Dave Kleikamp <shaggy@linux.vnet.ibm.com> Introduce new config options to simplify the ifdefs pertaining to the advanced debug registers for booke and 40x processors: CONFIG_PPC_ADV_DEBUG_REGS - boolean: true for dac-based processors CONFIG_PPC_ADV_DEBUG_IACS - number of IAC registers CONFIG_PPC_ADV_DEBUG_DACS - number of DAC registers CONFIG_PPC_ADV_DEBUG_DVCS - number of DVC registers CONFIG_PPC_ADV_DEBUG_DAC_RANGE - DAC ranges supported Beginning conservatively, since I only have the facilities to test 440 hardware. I believe all 40x and booke platforms support at least 2 IAC and 2 DAC registers. For 440, 4 IAC and 2 DVC registers are enabled, as well as the DAC ranges.
