vsprintf: Support phys_addr_t specifier unconditionally

2019-04-12T02:10:05+00:00

When phys_addr_t printf specifier support was first introduced in commit
1eebd14b7902 ("vsprintf: Add modifier for phys_addr_t"), it was enabled
only if CONFIG_CMD_NET was selected. Since physical addresses are not
unique to networking support it doesn't make sense to conditionally add
it in those cases only. Move support for it outside of the CMD_NET guard
so that the specifier is always supported.

lib: vsprintf: avoid overflow printing UTF16 strings

2019-02-13T08:40:06+00:00

We have to ensure while printing UTF16 strings that we do not exceed the
end of the print buffer.

lib: vsprintf: correct printing of Unicode strings

2018-09-23T19:55:29+00:00

The width and precision of the printf() function refer to the number of
characters not to the number of bytes printed.

efi_loader: rename utf16_strlen, utf16_strnlen

2018-09-23T19:55:29+00:00

The function names utf16_strlen() and utf16_strnlen() are misnomers.
The functions do not count utf-16 characters but non-zero words.
So let's rename them to u16_strlen and u16_strnlen().

In utf16_dup() avoid assignment in if clause.

vsprintf: Handle NULL with %pU

2018-07-25T12:57:44+00:00

At present a NULL pointer passed to printf for a %pU argument will cause
U-Boot to access memory at 0. Fix this by adding a check, and print
"(null)" instead.

lib: Add hexdump

2018-06-13T11:49:12+00:00

Often during debugging session it's very interesting to see
what data we were dealing with. For example what we write or read
to/from memory or peripherals.

This change introduces functions that allow to dump binary
data with one simple function invocation like:
------------------->8----------------
print_hex_dump_bytes("", DUMP_PREFIX_OFFSET, buf, len);
------------------->8----------------

which gives us the following:
