vsprintf.c: Always enable CONFIG_SYS_VSNPRINTF

2016-01-19T13:31:16+00:00

Enabling this function always removes some class of string saftey issues.
The size change here in general is about 400 bytes and this seems a reasonable
trade-off.

lib: split out strtoxxxx functions out of vsprintf.c

2015-12-14T00:07:30+00:00

To allow the various string to number conversion functions to be used
when using tiny-printf,split them out into their own file which gets
build regardless of what printf implementation is used.

lib: Split panic functions out of vsprintf.c

2015-12-14T00:07:30+00:00

To allow panic and panic_str to still be used when using tiny-printf,
split them out into their own file which gets build regardless of what
printf implementation is used.

lib/tiny-printf.c: Add tiny printf function for space limited environments

2015-11-23T15:56:07+00:00

This patch adds a small printf() version that supports all basic formats.
Its intented to be used in U-Boot SPL versions on platforms with very
limited internal RAM sizes.

To enable it, just define CONFIG_USE_TINY_PRINTF in your defconfig. This
will result in the SPL using this tiny function and the main U-Boot
still using the full-blown printf() function.

This code was copied from:
http://www.sparetimelabs.com/printfrevisited
With mostly only coding style related changes so that its checkpatch
clean.

The size reduction is about 2.5KiB. Here a comparison for the db-mv784mp-gp
(Marvell AXP) SPL:

Without this patch:
  58963   18536    1928   79427   13643 ./spl/u-boot-spl

With this patch:
  56542   18536    1956   77034   12cea ./spl/u-boot-spl

Note:
To make it possible to compile tiny-printf.c instead of vsprintf.c when
CONFIG_USE_TINY_PRINTF is defined, the functions printf() and vprintf() are
moved from common/console.c into vsprintf.c in this patch.

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.
