Alexey Dobriyan f284ce7269 PTRACE_POKEDATA consolidation Identical implementations of PTRACE_POKEDATA go into generic_ptrace_pokedata() function. AFAICS, fix bug on xtensa where successful PTRACE_POKEDATA will nevertheless return EPERM.

README

This port to the NEC V850E processor supports the following platforms:

   "sim"
	The gdb v850e simulator (CONFIG_V850E_SIM).

   "rte-ma1-cb"
	The Midas labs RTE-V850E/MA1-CB and RTE-V850E/NB85E-CB evaluation
	boards (CONFIG_RTE_CB_MA1 and CONFIG_RTE_CB_NB85E).  This support
	has only been tested when running with the Multi-debugger monitor
	ROM (for the Green Hills Multi debugger).  The optional NEC
	Solution Gear RTE-MOTHER-A motherboard is also supported, which
	allows PCI boards to be used (CONFIG_RTE_MB_A_PCI).

   "rte-me2-cb"
	The Midas labs RTE-V850E/ME2-CB evaluation board (CONFIG_RTE_CB_ME2).
     	This has only been tested using a kernel downloaded via an ICE
     	connection using the Multi debugger.  Support for the RTE-MOTHER-A is
     	present, but hasn't been tested (unlike the other Midas labs cpu
     	boards, the RTE-V850E/ME2-CB includes an ethernet adaptor).

   "as85ep1"
	The NEC AS85EP1 V850E evaluation chip/board (CONFIG_V850E_AS85EP1).

   "anna"
	The NEC `Anna' (board/chip) implementation of the V850E2 processor
	(CONFIG_V850E2_ANNA).

   "sim85e2c", "sim85e2s"
   	The sim85e2c and sim85e2s simulators, which are verilog simulations
	of the V850E2 NA85E2C/NA85E2S cpu cores (CONFIG_V850E2_SIM85E2C and
	CONFIG_V850E2_SIM85E2S).

   "fpga85e2c"
	A FPGA implementation of the V850E2 NA85E2C cpu core
	(CONFIG_V850E2_FPGA85E2C).

To get a default kernel configuration for a particular platform, you can
use a <platform>_defconfig make target (e.g., "make rte-me2-cb_defconfig");
to see which default configurations are possible, look in the directory
"arch/v850/configs".

Porting to anything with a V850E/MA1 or MA2 processor should be simple.
See the file <asm-v850/machdep.h> and the files it includes for an example of
how to add platform/chip-specific support.
