This patch allows user to simply select which GPIOs he wants to use
and access them via /dev/gpio_a0 or similar device with standard
gpio driver.
By default gpio names match pin names printed on the board. So when
enabling A3 pin, it will show as /dev/gpio_a3 in runtime. This name
can be changed in kconfig.
User can also select pin function (input, output, interrupt) as well
as standard pin settings like, pull up/down, output type
pushpull/open drain etc.
All pins that are exposed via boards goldpins are listed in Kconfig.
Extra pins that are supported by chiip but are not exposed for easy
usage are not listed.
To have this nice Kconfig configuration and for things to be easily
debugable/understandable it requires code to have big Kconfig and
header file with all possible definitions
Because of file sizes I decided to split gpio related kconfig and
header into separate files. Otherwise it would really make original
files hard to read and find anything.

This is copy of raspberrypi-pico with all occurences of raspberrypi replaced by
w5500-evb. Only the usbnsh defconfig is available, which is based on the
raspberrypi-pico:usbnsh defconfig, but enables the WIZnet W5500 Ethernet chip.
TCP/IP for IPv4 and IPv6 is enabled.

The DS1307 was used as board specific, but it is better move it to
stm32/common to be easily used by other boards as well.

This patch add support to use buttons example on raspberrypi-pico.
Note: unfortunately the raspberry-pico board doesn't have usables
buttons, then you need to add external buttons connected to GPIO16
and GPIO17.

Purpose: make the the os crash when busyloop with interrupt disable
Follow the arm gicv2 spec, if we want to use the IRQ and FIQ
simultaneously when not using the processor Security Externsions.
We should:
1. IRQ to Group 1 and FIQ to Group 0;
2. Set CICC_CTLR.FIQEn to 1;
Then in NuttX:
1. implement the arm_decodefiq and directly crash in it;
2. provide interface to change the IRQ to FIQ, e.g. change the
watchdog IRQ to FIQ, so the watchdog can trigger even with the
interrupt disabled (up_irq_save() called);

Current `CONFIG_PAGING` refers to an experimental implementation
to enable embedded MCUs with some limited RAM space to execute
large programs from some non-random access media.
On-demand paging should be implemented for the kernel mode with
address environment implementation enabled.
This commit adds support to autoleds and userleds for
raspberrypi-pico board. It uses the board LED connected
to GPIO 25.

As long as the GNSS feature is not used, GNSS RAM can be used as general memory.
This memory is 640KByte total, which is lower performance than the application RAM.
It is possible to locate text, data and bss into GNSS RAM and to use as heap area.
Since there were some cases in which the current modem reset
sequence did not reset the modem, the reset was ensured by
executing power off and power on of the modem.
This change adds support for the USB Transport Layer as described
in the bluetooth spec. Isochronous endpoints are not yet supported.
Because of limitations in the NuttX bluetooth stack, only one USB
device can be used. This driver will only allow one USB dongle to
use bluetooth.
A Laird USB BT4.2 dongle (from Mouser) was used for testing:
M/N BT851 1.0 1829, FCC ID:SQGBT850
lsusb: 04b4:f901 Cypress Semiconductor Corp. CYW20704A2
The following commands were used to test from the nsh prompt:
bt bnep0 scan start
bt bnep0 scan stop
bt bnep0 scan get
bt bnep0 info
The Linux gatttool was used to connect over wireless.
With the BDAddr found by "bt bnep0 info", start gatttool using:
gatttool -b BDAddr -I
Connect to the device using:
connect
Read the device name using the GAP device name UUID:
char-read-uuid 2a00
Part of the response is:
value: 41 70 61 63 68 65 20 4e 75 74 74 58
which is the string "Apache NuttX"
Usually the startup script is placed under /etc. The contents of the etc directory
are compiled and linked with Nuttx binary in the form of romfs. After startup,
it will be mounted by Nsh.
etc is generated by the different boards, that use genromfs and xxd tools to generate
and compile it into the Nuttx, for example: boards/arm/at32/at32f437-mini/tool/mkromfs.sh
The more common method is etc image generated from the content in the corresponding
board/arch/board/board/src/etc directory, and added by Makefile for example:
boards/sim/sim/sim/src/etc.
But in kernel/protected mode, Nuttx kernel and apps are run in different privileged/
non-privileged mode or the isolated binarys, so as that nsh should use syscall to
access Nuttx kernel by exported API. In this scenario, nsh can not mount the etc image
content, because that is generated in board and as a part of Nuttx kernel.
changes:
- move etc romfs mount from nsh to Nuttx, but keep the script to parse and execute.
- move and rename the related CONFIG, move customized nsh_romfsimg.h to etc_romfs.c
in boards, and no need declaration for romfs_img/romfs_img_len.
This commit changes and updates all configurations in Nuttx arch/board as much as possible,
but if any missing, please refer to the following simple guide:
- rename CONFIG_NSH_ROMFSETC to CONFIG_ETC_ROMFS, and delete CONFIG_NSH_ARCHROMFS in defconfig
- rename the etc romfs mount configs, for example CONFIG_NSH_FATDEVNO to CONFIG_ETC_FATDEVNO
- move customized nsh_romfsimg.h to etc_romfs.c in board/arch/board/board/src and no need
declaration for romfs_img/romfs_img_len.
- delete default nsh_romfsimg.h, if ROMFSETC is enabled, should generate and compile etc_romfs.c
in board/arch/board/board/src.
