lib: Add function to extract a number from the end of a string

2015-07-21T23:39:28+00:00

Split out the code in fdtdec which finds a number at the end of a string. It
can be useful in other situations.

mtd, nand: Move common functions from cmd_nand.c to common place

2015-06-29T19:10:11+00:00

Move common functions from cmd_nand.c (for calculating offset
and size from cmdline paramter) to common place, so they could
used from other commands which use mtd partitions.

For onenand the arg_off_size() is left in common/cmd_onenand.c.
It should use now the common arg_off() function, but as I could
not test onenand I let it there ...

dm: Add a panic_str() function to reduce code size

2015-04-23T15:05:52+00:00

The printf() in panic() adds about 1.5KB of code size to SPL when compiled
with Thumb-2. Provide a smaller version that does not support printf()-style
arguments and use it in two commonly compiled places.

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'.
