-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.
