Add board_pre_console_putc to deal with early console output

2011-12-09T13:44:22+00:00

This patch adds support for console output before the console is inited.
The main purpose of this is to deal with a very early panic() which would
otherwise cause a silent hang.

A new board_pre_console_putc() function is added to the board API. If
provided by the board it will be called in the event of console output
before the console is ready. This function should turn on all UARTs and
spray the character out if it possibly can.

The feature is controlled by a new CONFIG_PRE_CONSOLE_PUTC option.

DEBUG: Fix debug macros

2011-10-27T21:54:10+00:00

The current implementation of debug doesn't play well with GCC4.6.
This implementation also fixes GCC4.6 complaints about unused variables
while maintaining code size.

Also, drop the debugX() as that's not used anywhere anymore.

fdt: Add support for embedded device tree (CONFIG_OF_EMBED)

2011-10-26T19:38:59+00:00

This new option allows U-Boot to embed a binary device tree into its image
to allow run-time control of peripherals. This device tree is for U-Boot's
own use and is not necessarily the same one as is passed to the kernel.

The device tree compiler output should be placed in the $(obj)
rooted tree. Since $(OBJCOPY) insists on adding the path to the
generated symbol names, to ensure consistency it should be
invoked from the directory where the .dtb file is located and
given the input file name without the path.

This commit contains my entry for the ugliest Makefile / shell interaction
competition.

tftpput: add save_addr and save_size global variables

2011-10-26T19:35:43+00:00

We need something akin to load_addr to handle saving data.

Add setenv_ulong() and setenv_addr()

2011-10-26T19:32:42+00:00

It seems we put numbers and addresses into environment variables a lot.
We should have some functions to do this.

Move simple_itoa to vsprintf

This function is generally useful and shouldn't hide away in hush. It
has been moved as is.

buffers for use with DMA hardware.

Add getenv_ulong() to read an integer from an environment variable

This is not an uncommon operation in U-Boot, so let's put it in a common

cache: include asm/cache.h for ARCH_DMA_MINALIGN definition

2011-10-23T18:50:43+00:00

ARCH_DMA_MINALIGN will be used to allocate DMA buffers that are
aligned correctly.  In all current cases this means that the DMA
buffer will be aligned to at least the L1 data cache line size of
the configured architecture.  If the board configuration file
does not specify the architecture L1 data cache line size then the
maximum line size of the architecture is used to align DMA buffers.
