20 in this linker script. People using GCC >= 4.2 won't run into
21 this problem, because the "build-id" support will put some data
22 into the "notes" segment (at a non-zero load address).
23
24 To work around this, we force some data into both the "dummy"
25 segment and the kernel segment, so the dummy segment will get a
26 non-zero load address. It's not enough to always create the
27 "notes" segment, since if nothing gets assigned to it, its load
28 address will be zero. */

1This port to the NEC V850E processor supports the following platforms:
2
3 "sim"
4 The gdb v850e simulator (CONFIG_V850E_SIM).
5
6 "rte-ma1-cb"
7 The Midas labs RTE-V850E/MA1-CB and RTE-V850E/NB85E-CB evaluation
8 boards (CONFIG_RTE_CB_MA1 and CONFIG_RTE_CB_NB85E). This support
9 has only been tested when running with the Multi-debugger monitor
10 ROM (for the Green Hills Multi debugger). The optional NEC
11 Solution Gear RTE-MOTHER-A motherboard is also supported, which
12 allows PCI boards to be used (CONFIG_RTE_MB_A_PCI).
13
14 "rte-me2-cb"
15 The Midas labs RTE-V850E/ME2-CB evaluation board (CONFIG_RTE_CB_ME2).
16 This has only been tested using a kernel downloaded via an ICE
17 connection using the Multi debugger. Support for the RTE-MOTHER-A is
18 present, but hasn't been tested (unlike the other Midas labs cpu
19 boards, the RTE-V850E/ME2-CB includes an ethernet adaptor).
20
21 "as85ep1"
22 The NEC AS85EP1 V850E evaluation chip/board (CONFIG_V850E_AS85EP1).
23
24 "anna"
25 The NEC `Anna' (board/chip) implementation of the V850E2 processor
26 (CONFIG_V850E2_ANNA).
27
28 "sim85e2c", "sim85e2s"
29 The sim85e2c and sim85e2s simulators, which are verilog simulations
30 of the V850E2 NA85E2C/NA85E2S cpu cores (CONFIG_V850E2_SIM85E2C and
31 CONFIG_V850E2_SIM85E2S).
32
33 "fpga85e2c"
34 A FPGA implementation of the V850E2 NA85E2C cpu core
35 (CONFIG_V850E2_FPGA85E2C).
36
37To get a default kernel configuration for a particular platform, you can
38use a <platform>_defconfig make target (e.g., "make rte-me2-cb_defconfig");
39to see which default configurations are possible, look in the directory
40"arch/v850/configs".
41
42Porting to anything with a V850E/MA1 or MA2 processor should be simple.
43See the file <asm-v850/machdep.h> and the files it includes for an example of
44how to add platform/chip-specific support.
