arm: socfpga: Allow DWC2 UDC probing from OF

2015-12-20T02:36:50+00:00

The USB gadget framework does not support DM yet, so add this bit
to let DWC2 UDC probe from OF on platforms which support it.

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: Implement vprintf

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

Implement both printf and vprintf for a bit more flexibility, e.g.
allows the panic() function to work with tiny-printf.

dm: tegra: pci: Convert tegra boards to driver model for PCI

2015-12-01T13:26:36+00:00

Adjust the Tegra PCI driver to support driver model and move all boards over
at the same time. This can make use of some generic driver model code, such
as the range-decoding logic.

dm: timer: Support 64-bit counter

2015-12-01T13:23:51+00:00

There are timers with a 64-bit counter value but current timer
uclass driver assumes a 32-bit one. Modify timer_get_count()
to ask timer driver to always return a 64-bit counter value,
and provide an inline helper function timer_conv_64() to handle
the 32-bit/64-bit conversion automatically.

lib/tiny-printf.c: Support numbers bigger than 0xffff and misc updates

2015-11-23T15:56:08+00:00

With this patch now, the tiny printf() function also supports numbers
bigger than 0xffff. Additionally the code is simplified a bit and
some static variables are moved to function parameters. Also the
upper case hex variable output support is removed, as its not really
needed in this simple printf version. And removing it reduces the
complexity and the code size again a bit.

Here the new numbers, again on the db-mv784mp-gp (Armada XP):

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.

Add a circular memory buffer implementation

2015-11-20T03:27:50+00:00

This will be used to support console recording. It provides for a circular
buffer which can be written at the head and read from the tail. It supports
avoiding data copying by providing raw access to the data.

Drop config.h header from display_options.c

2015-11-20T03:27:50+00:00

Since common.h will always include this automatically, it is not needed.
