This makes a cleaner separation between the: driver, HCI UART and BT stack.
Also updated the naming to be more consistent (mp_bluetooth_hci_*).
Work done in collaboration with Jim Mussared aka @jimmo.
These addresses were initially chosen to match the nRF24 Arduino library
examples but they are byte-reversed. So change them to be on-air
compatible with the Arduino library.
Also, the data sheet for the nRF24 says that RX data pipes 1-5 must share
the same top 32-bits, and must differ only in the LSbyte. The addresses
used here (while correct because they are on TX pipe and RX pipe 0) are
misleading in this sense, because it looks like they were chosen to share
the top 32-bits per the datasheet.
With a SPI flash that has more than 16MB, 32-bit addressing is required
rather than the standard 24-bit. This commit adds support for 32-bit
addressing so that the SPI flash commands (read/write/erase) are selected
automatically depending on the size of the address being used at each
operation.
DS1822P sensors behave just like the DS18B20 except for the following:
- it has a different family code: 0x22
- it has only the GND and DQ pins connected, it uses parasitic power from
the data line

It seems that some cards do not tolerate releasing the card (by setting CS
high) after issuing CMD17 (and 18) and raising it again before reading
data. Somehow this causes the 0xfe data start marker not being read and
SDCard.readinto() is spinning forever (or until this byte is in the data).
This seems to fix weird behviour of SDCard.readblocks() returning different
data, also solved hanging os.mount() for my case with a 16GB Infineon card.

This patch renames the existing SPI flash API functions to reflect the fact
that the go through the cache:
mp_spiflash_flush -> mp_spiflash_cache_flush
mp_spiflash_read -> mp_spiflash_cached_read
mp_spiflash_write -> mp_spiflash_cached_write
