apps/modbus:  That completes a complete pass; all of the modbus files a little closer to NuttX coding style.  Still not compliant with naming conventions

Modbus: Change to more header files to make them a little more consistent with Nuttx coding stanards.  Still not very close

Modbus: Change to several header files to make them a little more consistent with Nuttx coding stanards.  Still not very close

drawline/drawLine should not take a boolean to select non lines caps or capping at both ends.  drawline/drawLine also needs to be able to put a line cap on one one end of a line

Add a 'capped' boolean parameter to all drawline/drawLine functions/methods.  The idea is that this will produce better joining between lines

More renaming: up_lcdinitialize->board_lcd_initialize, up_lcdgetdev->board_lcd_getdev, up_lcduninitialize->board_lcd_uninitialize

Rename pwm_devinit() to board_pwm_setup().  Add CONFIG_BOARDCTL_PWMTEST that will enable calling board_pwm_setup() from boardctl().  Replace calls to pwm_devinit() in apps/examples/pwm with calls to boardctl().  In all configurations that enable the apps/examples/pwm test, make sure that boardctl() suppoprt is properly enabled.

Kconfig files: If external graphics initialization is required, it depends on CONFIG_LIB_BOARDCTL and should set CONFIG_BOARDCTL_GRAPHICS

Rename up_nxdrvinit() to board_graphics_setup().  Add CONFIG_BOARDCTL_GRAPHICS that will enabled calls to board_graphics_setup() from boardctrl().  In apps/ and NxWidgts/, replace all calls to up_nxdrvinit with calls to boardctl().

Rename adc_devinit() to board_adc_setup().  Add support to the boardctl() interface so that it can call board_adc_setup() on behalf of an application.  Change apps/examples/adc to that is now calls boardctl() instead of adc_devinit() in order to initalize the ADC device.

rch_tcinitialize() and arch_tcunitinitialize() renamed to board_tsc_setup() and board_tsc_teardown().  These are not long called directly by applications but only indirectly throught the crappy boardctl() OS interface.

NSH initialization now calls boardctl(BOARDIOC_INIT) instead of board_app_initaliaze.  Modify all configurations:  Make sure that CONFIG_LIB_BOARDCTL=y appears wherever CONFIG_NSH_ARCHINIT=y appears.  Remove support for CONFIG_NSH_ARCHMAC.  It is not used and there are better ways to do that operation
