If CONFIG_CMD_TFTPPUT is not enabled, we want minimal code size impact
on the tftp code. This introduces a few more #ifdefs.

This commit reduces code size a little by making the ICMP handler only
available to tftpput. This is reasonable since it is the only user at

ATTR_VFAT condition requires multiple bits to be set but the present

In some cases, saving data in RAM as a file with FAT format is required.
This patch allows the file to be written in FAT formatted partition.

The usage is similar with reading a file.
First, fat_register_device function is called before file_fat_write function
in order to set target partition.
Then, file_fat_write function is invoked with desired file name,
start ram address for writing data, and file size.

This adds support for a new environment variable called 'fdtcontroladdr'. If
defined, the hex address is used as the address of the control fdt for U-Boot.

Note: I have not changed CONFIG_PRAM section as I already have an
outstanding patch on that.

This locates the device tree either embedded within U-Boot or attached to the
end as a separate binary.

When CONFIG_OF_CONTROL is defined, U-Boot requires a valid fdt. A check is
provided for this early in initialisation.
Signed-off-by: NSimon Glass <sjg@chromium.org>

This library provides useful functions to drivers which want to use
the fdt to control their operation. Functions are provided to:

- look up and enumerate a device type (for example assigning i2c bus 0,
     i2c bus 1, etc.)
- decode basic types from the fdt, like addresses and integers

While this library is not strictly necessary, it helps to minimise the
changes to a driver, in order to make it work under fdt control. Less
code is required, and so the barrier to switch drivers over is lower.

Additional functions to read arrays and GPIOs could be made available
here also.

This adds support for an FDT to be build as a separate binary file called
u-boot.dtb. This can be concatenated with the U-Boot binary to provide a
device tree located at run-time by U-Boot. The Makefile is modified to
provide this file in u-boot-dtb.bin.
Signed-off-by: NSimon Glass <sjg@chromium.org>

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.

competition.

ICMP packets can tell you when there is no server at the other end. It
is useful for tftp to figure this out, so that a quick error can be
displayed, rather than pointlessly retrying.

Currently part_efi.c allocates buffers for the gpt_header, the

incorrectly aligned for DMA operations.

This patch uses ALLOC_CACHE_ALIGN_BUFFER for the stack allocated
buffers and memalign to replace the malloc of the pte.

Currently the mmc_change_freq and mmc_startup functions allocates
buffers on the stack that are passed down to the MMC device driver.
These buffers could be unaligned to the L1 dcache line size.  This
causes problems when using DMA and with caches enabled.

This patch correctly cache alignes the buffers used for reading the
ext_csd data from an MMC device.

Currently, if a device read request is done that does not begin or end
on a sector boundary a stack allocated bounce buffer is used to perform
the read, and then just the part of the sector that is needed is copied
into the users buffer.  This stack allocation can mean that the bounce
buffer will not be aligned to the dcache line size.  This is a problem
when caches are enabled because unaligned cache invalidates are not
safe.

This patch uses ALLOC_CACHE_ALIGN_BUFFER to create a stack allocated
cache line size aligned bounce buffer.

Commit dc8bbea0 removed a local variable that is used in most ARM boards.
