Arjan van de Ven 5dfe4c964a [PATCH] mark struct file_operations const 2 Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

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.
