Alin Jerpelea a1c991d921 Merged in alinjerpelea/nuttx (pull request #963)
Move boards to boards folder

* boards: rename configs folder to boards

    This is the proposed layout after the change:

    boards: - folder containing board folders
            <board>: - name of each board
                    drivers: - extra drivers specific for platform
                    include: - header files for the boars
                    scripts: - extra scripts specific for platform
                        src: - board specific code
                      tools: - extra tools specific for platform
                    <config>: - board specific configuration(s)

    Note:
    <xxx> names are dependent on platform

    This is a logical change to aim to the arch layout but this is a
    huge change it should be done in several steps to lower the risk.

prompt "Execution memory"
default METRO_M4_RUNFROMFLASH
config METRO_M4_RUNFROMFLASH
bool "Run from FLASH"
select BOOT_RUNFROMFLASH
---help---
This is the normal configuration for building METRO M4 code.
config METRO_M4_RUNFROMSRAM
bool "Run from SRAM"
select BOOT_RUNFROMISRAM
---help---
During early bring-up, it is safer to execute entirely from
SRAM until you are confident in the initialization logic.
Then you can safely switch to FLASH.
REVISIT: This auto-selects CONFIG_BOOT_RUNFROMISRAM but I have
found, with some difficulty, that that choice still defaults to
CONFIG_BOOT_RUNFROMFLASH, causing link-time failures when running
from SRAM.
endchoice # Execution memory
config METRO_M4_32KHZXTAL
bool "32.768 KHz XTAL"
default n
---help---
According to the schematic, a 32.768 KHz crystal is installed on
board. However, I have been unable to use this crystal and thought
perhaps it is missing or defective on my board (there is a metal
package that could be a crystal on board, but I am not certain).
Another, more likely option is that there is a coding error on my
part that prevents the 32.768 KHz crystal from usable(?)
The configuration defaults to using the always-on OSCULP32 as the
slow clock source. This option will select instead XOSC32 as the
slow clock source.
