lib: provide function hextoull()

2024-11-13T14:14:23+00:00

We often convert hexadecimal strings to hextoull(). Provide a wrapper
function to simple_strtoull() that does not require specifying the radix.

lib: Handle a special case with str_to_list()

2024-08-07T14:49:10+00:00

The current implementation can return an extra result at the end when
the string ends with a space. Fix this by adding a special case.

lib: Remove inclusion from these files

2023-12-21T13:54:37+00:00

After some header file cleanups to add missing include files, remove
common.h from all files in the lib directory. This primarily means just
dropping the line but in a few cases we need to add in other header
files now.

lib: Add a function to split a string into substrings

2023-01-23T23:11:39+00:00

Some environment variables provide a space-separated list of strings. It
is easier to process these when they are broken out into an array of
strings.

Add a utility function to handle this.

lib: Add a way to find the postiion of a trailing number

2022-04-25T14:00:03+00:00

At present it is not possible to find out which part of the string is the
number part and which is before it. Add a new variant which provides this
feature, so we can separate the two in the caller.

lib: Fix a few bugs in trailing_strtoln()

2022-04-25T14:00:03+00:00

At present this has a minor bug in that it reads the byte before the
start of the string, if it is empty. Also it doesn't handle a
non-numeric prefix which is only one character long.

Fix these bugs with a reworked implementation. Add a test for the second
case. The first one is hard to test.

doc: replace @return by Return:

2022-01-19T17:11:34+00:00

Sphinx expects Return: and not @return to indicate a return value.

find . -name '*.c' -exec \
sed -i 's/^\(\s\)\*\(\s*\)@return\(\s\)/\1*\2Return:\3/' {} \;

find . -name '*.h' -exec \
sed -i 's/^\(\s\)\*\(\s*\)@return\(\s\)/\1*\2Return:\3/' {} \;

lib: Allow using 0x when a decimal value is requested

2021-08-02T17:32:14+00:00

U-Boot mostly uses hex for value input, largely because addresses are much
easier to understand in hex.

But in some cases a decimal value is requested, such as where the value is
small or hex does not make sense in the context. In these cases it is
sometimes useful to be able to provide a hex value in any case, if only to
resolve any ambiguity.

Add this functionality, for increased flexibility.

lib: Move common digit-parsing code into a function

2021-08-02T17:32:14+00:00

The code to convert a character into a digit is repeated twice in this
file. Factor it out into a separate function. This also makes the code a
little easier to read.

lib: Drop unnecessary check for hex digit

2021-08-02T17:32:14+00:00

If we see 0x then we can assume this is the start of a hex value. It
does not seem necessary to check for a hex digit after that since it will
happen when parsing the value anyway.

Drop this check to simplify the code and reduce size. Add a few more test
cases for when a 0x prefix is used.
