c37ade9aeb Correct NO_TIMER index value for SAMD21. 
We check validity by ensuring it's lower than the total number of
timers. 0 is a terrible number for the NO_TIMER value because its
valid even though it shouldn't be.

8157248189 Move usb read finish into interrupt. 
Having the `active_read = false` in the background function left
a chance that a new_write occurs before active_read is set to false.

In that case, we'll read the appropriate data rather than write it
and never clear the active write.

Hopefully fixes #655.

bdc875e602 drivers/memory/spiflash: Fix bugs in and clean up read/write functions. 
mp_spiflash_read had a bug in it where "dest" and "addr" were incremented
twice for a certain special case.  This was fixed, which then allowed the
function to be simplified to reduce code size.

mp_spiflash_write had a bug in it where "src" was not incremented correctly
for the case where the data to be written included the caching buffer as
well as some bytes after this buffer.  This was fixed and the resulting
code simplified.

e0bc438e4b py/obj.h: Move declaration of mp_obj_list_init to objlist.h. 
If this function is used then objlist.h is already included to get the
definition of mp_obj_list_t.

d4b55eff44 py/misc.h: Remove unused count_lead_ones() inline function. 
This function was never used for unicode/utf8 handling code, or anything
else, so remove it to keep things clean.

033c32e694 esp8266/esp_mphal.h: Fix I2C glitching by using input mode for od_high. 
Certain pins (eg 4 and 5) seem to behave differently at the hardware level
when in open-drain mode: they glitch when set "high" and drive the pin
active high for a brief period before disabling the output driver.  To work
around this make the pin an input to let it float high.

1345093401 stm32/qspi: Do an explicit read instead of using memory-mapped mode. 
Using an explicit read eliminates the need to invalidate the D-cache after
enabling the memory mapping mode, which takes additional time.

626d6c9756 stm32/storage: Introduce MICROPY_HW_ENABLE_INTERNAL_FLASH_STORAGE cfg. 
This config variable controls whether to support storage on the internal
flash of the MCU.  It is enabled by default and should be explicitly
disabled by boards that don't want internal flash storage.

d1c4bd69df stm32/storage: Remove all SPI-flash bdev cfg, to be provided per board.

1e4caf0b1e stm32/storage: Merge all misc block-dev funcs into a single ioctl func. 
It makes it cleaner, and simpler to support multiple different block

ioctl operations.

a739b35a96 drivers/memory/spiflash: Change to use low-level SPI object not uPy one. 
This patch alters the SPI-flash memory driver so that it uses the new
low-level C SPI protocol (from drivers/bus/spi.h) instead of the uPy SPI
protocol (from extmod/machine_spi.h).  This allows the SPI-flash driver to
be used independently from the uPy runtime.

58ebeca6a9 drivers/bus: Pull out software SPI implementation to dedicated driver. 
This patch takes the software SPI implementation from extmod/machine_spi.c
and moves it to a dedicated file in drivers/bus/softspi.c.  This allows the
SPI driver to be used independently of the uPy runtime, making it a more
general component.
