vsprintf: Add modifier for phys_addr_t

2014-11-23T11:49:01+00:00

Provide a new modifier to vsprintf() to print phys_addr_t variables to
avoid having to cast or #ifdef when printing them out. The %pa modifier
is used for this purpose, so phys_addr_t variables need to be passed by
reference, like so:

	phys_addr_t start = 0;

	printf("start: %pa\n", &start);

Depending on the size of phys_addr_t this will print out the address
with 8 or 16 hexadecimal digits following a 0x prefix.

include: move various macros to include/linux/kernel.h

2014-11-20T16:28:25+00:00

U-Boot has imported various utility macros from Linux
scattering them to various places without consistency.

In include/common.h are min, max, min3, max3, ARRAY_SIZE, ALIGN,
container_of, DIV_ROUND_UP, etc.
In include/linux/compat.h are min_t, max_t, round_up, round_down,
etc.
We also have duplicated defines of min_t in some *.c files.

Moreover, we are suffering from too cluttered include/common.h.

This commit moves various macros that originate in
include/linux/kernel.h of Linux to their original position.

Note:
This commit simply moves the macros; the macros roundup,
min, max, min2, max3, ARRAY_SIZE are different
from those of Linux at this point.

lib:vsprintf: reduce scope of pack_hex_byte

2014-07-18T21:53:23+00:00

pack_hex_byte is only used when CONFIG_CMD_NET is
defined so limit it to that scope. This prevents
a clang warning.

lib: fix return codes when CONFIG_SYS_VSNPRINTF is enabled

2014-01-24T21:59:07+00:00

When CONFIG_SYS_VSNPRINTF is enabled, it protects print operations
such as sprintf, snprintf, vsnprintf, etc., from buffer overflows.
But vsnprintf_internal includes the terminating NULL character in
the calculation of number of characters written. This affects sprintf
and snprintf return values. Fix this issue by setting pointer 'str'
back to the location of the '\0'.

vsprintf:fix: Change type returned by ustrtoul

2012-12-13T18:46:02+00:00

The ustrtoul shall convert string defined size (e.g. 1GiB) to unsigned
long type (as its name implies).

Up till now it had returned int, which might cause problems with large
numbers (GiB range), when interpreted as U2 signed numbers.

lib/vsprintf.c: don't special-case pointers to address null

2012-11-02T22:13:29+00:00

The %p format of printf() would print a pointer to address null as
"(null)".  This makes sense in a real OS where a NULL pointer must
never be dereferenced, but this is a bootloader, and there are cases
where accessing the data at address null makes perfect sense.

Remove the special case in lib/vsprintf.c using "#if 0" with a comment
to make clear this was an intentional change and to stop re-adding
this code.
