mbed patch for Infinity
-----------------------
Without ld script patch vector table it doesn't place vector table in binary file.
And clock setting is changed as Infinity uses internal oscillator instead of exteranl crystal.

===========================
If FSEC of flash config at 0x400-40F is changed accidentally SWD/JTAG debug access will be lost and very difficult to get back.
For example, high level adapter like stlink cannot work to get access back after FSEC is changed. To regain the chip to be programmable low level DAP inteface like JTAG, CMSIS-DAP or OpenSAD.

TAP
---
http://openocd.sourceforge.net/doc/html/TAP-Declaration.html#TAP-Declaration
jtag newtap chipname tapname configparams...
hla newtap chipname tapname configparams...
swd newtap chipname tapname configparams...
cmsis-dap newtap chipname tapname configparams...
The tapname reflects the role of that TAP, and should follow this convention:
bs – For boundary scan if this is a separate TAP;
cpu – The main CPU of the chip, alternatively arm and dsp on chips with both ARM and DSP CPUs, arm1 and arm2 on chips with two ARMs, and so forth;
etb – For an embedded trace buffer (example: an ARM ETB11);
flash – If the chip has a flash TAP, like the str912;
jrc – For JTAG route controller (example: the ICEPick modules on many Texas Instruments chips, like the OMAP3530 on Beagleboards);
tap – Should be used only for FPGA- or CPLD-like devices with a single TAP;
unknownN – If you have no idea what the TAP is for (N is a number);
when in doubt – Use the chip maker's name in their data sheet. For example, the Freescale i.MX31 has a SDMA (Smart DMA) with a JTAG TAP; that TAP should be named sdma.
-irlen NUMBER
The length in bits of the instruction register, such as 4 or 5 bits.
Target
------
http://openocd.sourceforge.net/doc/html/CPU-Configuration.html#CPU-Configuration
target create target_name type configparams...
$target_name configure configparams...
-chain-position dotted.name – names the TAP used to access this target.
-endian (big|little) – specifies whether the CPU uses big or little endian conventions
-event event_name event_body – See Target Events. Note that this updates a list of named event handlers. Calling this twice with two different event names assigns two different handlers, but calling it twice with the same event name assigns only one handler.
-work-area-backup (0|1) – says whether the work area gets backed up; by default, it is not backed up. When possible, use a working_area that doesn't need to be backed up, since performing a backup slows down operations. For example, the beginning of an SRAM block is likely to be used by most build systems, but the end is often unused.
-work-area-size size – specify work are size, in bytes. The same size applies regardless of whether its physical or virtual address is being used.
-work-area-phys address – set the work area base address to be used when no MMU is active.
-work-area-virt address – set the work area base address to be used when an MMU is active. Do not specify a value for this except on targets with an MMU. The value should normally correspond to a static mapping for the -work-area-phys address, set up by the current operating system.
-rtos rtos_type – enable rtos support for target, rtos_type can be one of auto|eCos|ThreadX| FreeRTOS|linux|ChibiOS|embKernel See RTOS Support.

flash bank name driver base size chip_width bus_width target [driver_options]
name ... may be used to reference the flash bank in other flash commands. A number is also available.
driver ... identifies the controller driver associated with the flash bank being declared. This is usually cfi for external flash, or else the name of a microcontroller with embedded flash memory. See Flash Driver List.
base ... Base address of the flash chip.
size ... Size of the chip, in bytes. For some drivers, this value is detected from the hardware.
chip_width ... Width of the flash chip, in bytes; ignored for most microcontroller drivers.
bus_width ... Width of the data bus used to access the chip, in bytes; ignored for most microcontroller drivers.
target ... Names the target used to issue commands to the flash controller.
driver_options ... drivers may support, or require, additional parameters. See the driver-specific documentation for more information.

mbed fix for Infinity
=====================
Without linker script patch it doesn't place vector table in final binary.
And clock is configured to 48MHz using internal clock reference and FLL multiplication.
mbed/targets/cmsis/TARGET_Freescale/TARGET_K20D50M/system_MK20D5.c
Fix SystemInit: clock setup for internal clock. Inifinity has no external Xtal.
mbed/targets/cmsis/TARGET_Freescale/TARGET_K20D50M/cmsis_nvic.c
Fix NVIC vector address of firmware 0x1000 instead of 0x0
mbed/targets/cmsis/TARGET_Freescale/TARGET_K20D50M/TOOLCHAIN_GCC_ARM/MK20D5.ld
Fix memory map for Infinity bootloader
Flash starts at 0x1000
No flash config bytes sector
USBDevice/USBDevice/USBHAL_KL25Z.cpp
Fix USB clock setup, see below.
2015/01/04 Based on mbed-sdk @2f63fa7d78a26.
Kinetis USB config
==================
Clock source: Internal reference clock wth FLL
SIM_SOPT[USBSRC] = 1(MCGPLLCLK/MCGFLLCLK)
SIM_SOPT[PLLSEL] = 0(MCGFLLCLK)
Clock dividor:
SIM_CLKDIV2[USBDIV] = 0
SIM_CLKDIV2[USBFAC] = 0
Clock enable:
SIM_SCGC4[USBOTG] = 1

OpenOCD config files for Kinetis
================================
http://nemuisan.blog.bai.ne.jp/?eid=192848#OPENOCD
These are needed for SWD debug and programing bootloader. To flash keyboard firmware use 'dfu-util'.
Flash security of Freescale kinetis
-----------------------------------
If FSEC of flash config is changed accidentally SWD/JTAG you can't get debug access until doing 'mdm mass_erase' with JTAG, CMSIS-DAP or OpenSAD adapter. HLA(high level adapter) like stlink doesn't work for this.
Example
-------
Debug:
$ openocd -s tool -f tool/openocd.cfg
$ arm-none-eabi-gdb build/infinity.elf -ex "target remote localhost:3333"
Flash bootloader:
$ openocd -s tool -f tool/openocd.cfg -c "mt_flash kiibohd_bootloader.bin"
Infinity SWD pinout
-------------------
SWD pins are placed next to reset button; SWD_CLK, SWD_DIO, GND, VCC from top.
Note that RESET is also needed to get full control with OpenOCD.
