Benoît Thébaudeau 0f137e4bdd cc2538: uart: Make uart_isr() static
This function is only supposed to be used by uart.c, so it should be
static.

Oliver Schmidt 1d934db654 Reduce overlap on "scroll".
When using the 'down' button on a certain number of lines curently displayed at the bottom of the screen is redisplayed at the top of the screen. Given our usually small screen size and often large pages requiring many 'down' operations the number 'four' seems too generous so lets reduce it to 'two'.

Oliver Schmidt f6b315a17f Fixed history handling.
- The wraparound handling when using the history with the 'back' button is actually depending on history_last being unsigned (which is the default for cc65) so define it explicitly as unsigned to make it work on other targets too.
- As there's no 'forward' button it doesn't make sense to keep history entries after using them with the 'back' button. Clearing them on use on the other hand avoids an "infinite history".

Oliver Schmidt e6903e4e7e Recognize HTTPS.
Although we for sure don't support HTTPS we need to recognize it. Nowadays it has become pretty usual to redirect HTTP URLs to HTTPS URLs in order to force privacy (thanks, NSA !). So far our redirection handler didn't recognize an HTTPS URL as abslute URLs and therefore appended it to the curent URL. This led to an endless redirection loop. Now we recognize the HTTPS redirection and generate a minimal document on the fly to inform the user of (for us unrachable) the redirection target.

HTML links with HTTPS URLs are treated just like fragment-only links meaning that they get simply completely ignored.

Oliver Schmidt 448fa88ad8 Fixed handling of empty URLs.
The code to trim spaces from the end of the URL behaved undefined if the URL was empty. That scenario is far from hypothetic as i.e. pressing the 'back' button with no (more) entry in the history yields an empty URL.

Oliver Schmidt 8b0a7a697f Filter excessive newlines.
The way our HTML parser triggers newlines is a guess at best. On the other hand our screen estate is severely limited. Instead of trying to (further) improve the way we translate tags to newlines it seems more reasonable to simply never render more than two successive empty lines.

Benoît Thébaudeau b92a5afcc4 cc2538: ccm: Make it possible to use the interrupt
Using the AES interrupt allows the user process not to waste time
polling for the completion of the operation. This time can be used by
the user process to do something else, or to let the system enter PM0.

Since the system is now free to perform various operations during a
crypto operation, a protection of the crypto resource is added, and PM1+
is prohibited in order not to stall crypto operations.

George Oikonomou d28eb023ef Remove CC2530 and CC2538 dummy watchdog_stop()
The CC2538 the WDT cannot be stopped once it has been started.
The CC2530/1 WDT can be stopped if it is running in timer mode,
but it cannot be stopped once it has been started in watchdog mode.

Both platforms currently provide "dummy" implementations of `watchdog_stop()`,
one does nothing and the other one basically re-maps `_stop()` to
`_periodic()`.

This was originally done in order to provide implementations for all prototypes
declared in `core/dev/watchdog.h`. In hindsight and as per the discussion
in #1088, this is bad practice since, if the build succeeds, the caller will
expect that the WDT has in fact been stopped, when in reality it has not.

Since the feature (stopping the WDT) is unsupported by the hardware, this pull
removes those dummy implementations. Thus, we will now be able to reliably
detect - at build time - attempts at using this unsupported feature.

Oliver Schmidt cdd289a7ff Ignore fragment-only links.
We don't handle URLs with fragments exactly ;-) well - meaning we send the fragment part to the server and we don't display the document starting at the anchor tag. Instead of adding the missing capabilities and thus adding lots of code I instead opted to simply ignore fragment-only links. This approach is based on the practical knowledge that fragments are primarily used for intra-document navigation - and are as such fragment-only links. And as we ignore them anyway when displaying the document it's more ergonomic to not have those links in the first place.

Oliver Schmidt 9b9b92be06 Improved parsing of <SCRIPT> tag.
Complex script code tends to contain other tags inside strings. As we generally don't parse strings we erroneously interpreted those tags. The easiest workaround is to not interpret tags at all until the </SCRIPT> tag is found.

Oliver Schmidt 980d055f72 Allow for attributes in <li> tags.
parse_tag() is called both for attributes inside a tag and the end of the tag itself. For most tags parse_tag() doesn't distinguish both cases. This means that the "tag action" is additionally triggered for every tag attribute. When the tag "action" is setting some state this doesn't hurt. For many tags the "tag action" is to render a newline. Superfluous newlines are sort of acceptable to keep the code as small as possible. However the <li> "tag action" is to render a newline followed by an asterisk - and superfluous asterisks are ugly so we check for <li> if parse_tag() was called for the end of the tag itself.

Oliver Schmidt a56af59f40 Avoid randomly "eating" blanks.
At the time do_word() is called s.word[s.wordlen] is undefined. So it doesn't make sense to make decisions based on its value - and in fact I don't see why it was necessary/desirable in the first place.

cc2538: Fix and improve .data/.bss initialization
2015-05-23 18:50:57 +01:00
Benoît Thébaudeau 1cd3c9e7e5 cc2538: Initialize .data/.bss using ROM functions
This is safer because the previous code assumed that the start and end
VMAs of .data and .bss were word-aligned, which is not always the case,
so the initialization code could write data outside these sections. The
ROM functions support any address boundary.

This is faster because the ROM functions are ultra optimized, using
realignment and the LDM/STM instructions, which is much better than the
previous simple loops of single word accesses.

This is smaller because the ROM functions don't require to add any code
to the target device other than simple function calls.

This makes the code simpler and more maintainable because standard
functions are not reimplemented and no assembly is used.

Note that this is also faster and smaller than the corresponding
functions from the standard string library.

Benoît Thébaudeau 0de729572b cc2538: Word-align .data LMA
In order to be fast, the reset_handler() function uses word accesses to
initialize the .data output section. However, most toolchains do not
automatically force the alignment of an output section LMA to use the
maximum alignment of all its input sections. Because of that, assuming
that .data contains some words, the LMA of the .data output section was
not word-aligned in some cases, resulting in an initialization performed
using slow unaligned word accesses.

This commit forces the alignment of the LMA of the .data output section
with a word boundary in order to always use fast aligned word accesses
to read the .data load area.

Note that this solution is better than using ALIGN_WITH_INPUT, both
because the latter is a new feature incompatible with older toolchains,
and because it could create a big gap between _etext and the LMA of
.data if strongly-aligned data were added to .data, although only a word
alignment is required here.

The same considerations apply to the VMA of .data. However, it is
already automatically word-aligned, both because .data contains words,
and because the end VMA of the previous output section (.socdata) is
word-aligned. Moreover, if the VMA of .data were forcibly word-aligned,
then a filled gap could appear at the beginning of this section if
strongly-aligned data were added to it, thus wasting flash memory.
Consequently, it's better not to change anything for the VMA of .data,
all the more it's very unlikely that it does not contain any word and
that the end VMA of .socdata becomes non-word-aligned, and this would
only result in a slower initialization.

Benoît Thébaudeau 0d260f61a0 cc2538: Fix .data LMA/VMA mismatch with some toolchains
Some toolchains, like Sourcery CodeBench Lite 2013.05-23 arm-none-eabi
(http://sourcery.mentor.com/public/gnu_toolchain/arm-none-eabi/)
automatically force the alignment of an output section LMA to use the
maximum alignment of all its input sections. This toolchain uses GNU
binutils 2.23, and this automatic behavior is the same as the manual
behavior of the ALIGN_WITH_INPUT feature of GNU binutils 2.24+.

This behavior is not an issue per se, but it creates a gap between
_etext and the LMA of the .data output section if _etext does not have
the same alignment, while reset_handler() initialized this section by
copying the data from _etext to its VMA, hence an offset in the
addresses of loaded data, and missing data.

This commit fixes this issue by making reset_handler() directly use the
LMA of the .data section using LOADADDR(.data), rather than assuming
that _etext is this LMA.

Matthieu Baerts 78b6b50194 Z1: tmp102: simple: fixed wrong cast
When using this code:

    (int8_t)tmp102_read_temp_x100() / 100

Only the first value is casted into a int8_t type.

tmp102_read_temp_x100() returns the temperature in Celcius * 100. Most of
the time this value will be lower than -2^7 and higher than 2^7 (+/- 1.27°C).

The cast is not needed but a comment about this implicit cast has been added.
