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.

The default configuration is set up run from IRAM. However, the
|
|
current (2016-11-14) OpenOCD for ESP32 does not support writing to
|
|
FLASH. This option sets up the linker scripts to support execution
|
|
from IRAM. In this case, OpenOCD can be used to load directly into
|
|
IRAM.
|
|
|
|
At this stage the nuttx image is small enough to be entirely memory-
|
|
resident. Once board support is more mature you can add flash cache
|
|
mapping code to run from SPI flash after initial boot. There are at
|
|
least two possible approaches you could take: You can add the flash
|
|
cache mapping code into nuttx directly, so it is self-contained -
|
|
early nuttx initialization runs from IRAM and enables flash cache,
|
|
and then off you go. Or you can use the esp-idf software bootloader
|
|
and partition table scheme and have nuttx be an esp-idf "app" which
|
|
allows interoperability with the esp-idf system but makes you
|
|
reliant on the esp-idf design for these parts. Both are possible.
