b8da836650 image: Rename fit_image_check_hashes() to fit_image_verify()
This is the main entry point to the FIT image verification code. We will
be using it to handle image verification with signatures, so rename the
function.

b7260910dc image: Convert fit_image_hash_set_value() to static, and rename
This function doesn't need to be exported, and with verification
we want to use it for setting the 'value' property in any node,

859e92b775 image: Move timestamp #ifdefs to header file
Rather than repeat the line
 #if defined(CONFIG_TIMESTAMP) || defined(CONFIG_CMD_DATE) || \
	defined(USE_HOSTCC)

everywhere, put this in a header file and #define IMAGE_ENABLE_TIMESTAMP
to either 1 or 0. Then we can use a plain if() in most code and avoid
the #ifdefs.

The compiler's dead code elimination ensures that the result is the same.

88f95bbadd libfdt: Add fdt_next_subnode() to permit easy subnode iteration
Iterating through subnodes with libfdt is a little painful to write as we
need something like this:

for (depth = 0, count = 0,
	offset = fdt_next_node(fdt, parent_offset, &depth);
     (offset >= 0) && (depth > 0);
     offset = fdt_next_node(fdt, offset, &depth)) {
	if (depth == 1) {
		/* code body */
	}
}

Using fdt_next_subnode() we can instead write this, which is shorter and
easier to get right:

for (offset = fdt_first_subnode(fdt, parent_offset);
     offset >= 0;
     offset = fdt_next_subnode(fdt, offset)) {
	/* code body */
}

Also, it doesn't require two levels of indentation for the loop body.

a7e62be091 avr32: fix relocation address calculation
Commit 1865286466 (Introduce generic link
section.h symbol files) changed the __bss_end symbol type from char[] to
ulong. This led to wrong relocation parameters which ended up in a not working
u-boot. Unfortunately this is not clear to see cause due to RAM aliasing we
may get a 'half-working' u-boot then.

Fix this by dereferencing the __bss_end symbol where needed.

da34aae5fb bfin: Move gpio support for bf54x and bf60x into the generic driver folder.
The gpio spec for bf54x and bf60x differ a lot from the old gpio driver for bf5xx.
A lot of machine macros are used to accomodate both code in one gpio driver.
This patch split the old gpio driver and move new gpio2 support to the generic
gpio driver folder.

- To enable gpio2 driver, macro CONFIG_ADI_GPIO2 should be defined in the board's
config header file.
- The gpio2 driver supports bf54x, bf60x and future ADI processors, while the
older gpio driver supports bf50x, bf51x, bf52x, bf53x and bf561.
- All blackfin specific gpio function names are replaced by the generic gpio APIs.
