treewide: Use 16-bit Unicode strings

2022-02-03T20:53:28+00:00

At present we use wide characters for Unicode but this is not necessary.
Change the code to use the 'u' literal instead. This helps to fix build
warnings for sandbox on the Raspberry Pi.

lib: printf code %pUs for GUID text representation

2022-01-19T15:16:33+00:00

In different places text representations are used for GUIDs, e.g.

* command efidebug
* command part list for GPT partitions

To allow reducing code duplication introduce a new printf code %pUs.
It will call uuid_guid_get_str() to get a text representation. If none is
found it will fallback to %pUl and print a hexadecimal representation.

global: Convert simple_strtoul() with hex to hextoul()

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

It is a pain to have to specify the value 16 in each call. Add a new
hextoul() function and update the code to use it.

Add a proper comment to simple_strtoul() while we are here.

lib/vsprintf.c: remove unused ip6_addr_string()

2021-07-15T22:44:36+00:00

There's currently no user of %p[iI]6, so including ip6_addr_string()
in the image is a waste of bytes. It's easy enough to have the
compiler elide it without removing the code completely.

The closest I can find to anybody "handling" ipv6 in U-Boot currently
is in efi_net.c which does

        if (ipv6) {
                ret = EFI_UNSUPPORTED;

As indicated in the comment, it can easily be put back, but preferably
under a config knob.

lib/vsprintf.c: implement printf() in terms of vprintf()

2021-07-15T22:44:36+00:00

This saves some code, both in terms of #LOC and .text size, and it is
also the normal convention that foo(...) is implemented in terms of
vfoo().
