powerpc/booke: Introduce new CONFIG options for advanced debug registers
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.
