power management infrastructure. This app demonstrates use of the
hooks to implement Low Power State and Tickless idle power saving
policies.

There's no reason to require callers to cast their data to uint8_t *
when the data might e.g. originate in a packed struct or some other
data type. Instead, be nice to callers and let them use any pointer
they want. Additionally, declare the TX buffer as a const pointer so
unnecessary typecasts aren't needed for that either (if the data
originates in a const location).

The buffers aren't guaranteed to be aligned so that they're always
aligned for uint16_t or uint32_t data. Use the available unaligned

These were not actually used anywhere and weren't correct (at least

This only worked before because the preprocessor was

This patch adds a very simple UART sample application which demonstrates
how to use the UART APIs. This sample is also useful to quickly verify
if a given UART driver is working properly. For now, the application
tests uart_poll_in() and uart_poll_out() APIs only, but new APIs should
be added in future.

Currently the build system has hardcoded values for the -march/-mcpu
which identify what architecture should be used when compiling ARM code.
For processors such as the STM32 this will need to be defined by a per

When configured at a frequency of 2MHz, a transaction writing
3 bytes and reading 1 byte fails silently (last byte cannot be
read back from the device). Enabling CONFIG_SPI_DEBUG fixes the
issue.
Scope traces show that the transaction (from /CS assert to /CS
deassert) takes 14us and there is activity on the MOSI line
after /CS is deasserted. A transaction writing 2 bytes and reading
3 bytes take 22us.
The issue is due to the fact that completed() deasserts /CS after
the driver has put 3 bytes in the TXFIFO and taken 1 byte from RXFIFO.
Just because the last byte made it to the TXFIFO, it doesn't mean that
it was put on the MOSI line.
The fix:
For a transaction sending T bytes and expecting R bytes, let N=max(T,R).
Send exactly N bytes and wait for exactly N bytes (or an error). This
way, we are sure that all the bytes were sent to the target device.
Also:
Stop calling pull_data() after every byte sent, it might take a while
for a byte to show up in RXFIFO.
If RFS bit is set, stop sending bytes (will be really useful with a
bigger RFT).
Flushing RXFIFO in spi_intel_transceive() is not needed anymore.

bluetooth/shell and bluetooth/tester need to be disabled on
galileo and minnowboard respectively. On these platforms,
the IRQ for the UART console and the H4 are the same IRQ line.
IRQ_CONNECT() is being called on the same IRQ line twice, and
it's only through linker luck that these tests work at all
since one driver will "win" when the mapping is set up at build
time by gen_idt.
gen_idt was supposed to break the build in this situation but
was bugged. The next patch in the series fixes gen_idt.

A couple paragraphs contain ambiguous verbs that are unclear.
(For example: Line 23. Does the kernel perform a busy-wait,
or does it merely permit a task or fiber to perform a busy-wait?)
Based on original, I guess the latter and attempted to correct this
in the docs.
Also fixed spelling error.

In zsh the value of $0 depends on the FUNCTION_ARGZERO option
which is set by default. FUNCTION_ARGZERO, when it is set, sets
$0 temporarily to the name of the function/script when executing
a shell function or sourcing a script. POSIX_ARGZERO option,
when it is set, exposes the original value of $0 in spite of the
current FUNCTION_ARGZERO setting.
This patch allows to source the project environment file from
both zsh and bash. It also removes the -z option from the
basename command which is missing in OS X.
