Makefile: Support totally quiet output with -s
"-s" is a command line option to the make tool, to suppress normal output,
something to the effect of prepending every line with '@' in the Makefile.
However with our V={0|1} support, we now print the shortened command line
output in any case (even with V=1, in addition to the long line!).
Normally -s helps to not miss non-fatal warnings, which tend to scroll out
of the window easily.
Introduce a new Makefile variable ECHO, to control the shortened output.
We only set it in the (current default) V=0 case, and replace every
occurence of "@echo" with that variable.
When the user specifies "-s", we set ECHO to some magic string which
changes the output line into a comment, so the output is suppressed.
Beside suppressing every output for "-s", we also avoid the redundant
short output when compiling with V=1.
This changes the output to:
==========

Makefile: use git describe for BUILD_STRING
Currently, the BUILD_STRING is just 7-digits git hash. It is true
we can identify which version is running, but we can not get a quick
idea about how new or old it is.
The command "git describe" provides us a bit more useful information
in the format of:
(tag-name)-(number of commits on top the tag)-g(7 digits hash)
I added some options:
--always
Make "git describe" work without any tag in case the upstream
ATF is cloned, but all the tags are locally dropped.
--tags
Use any tag instead of only annotated tags. In ATF, only some
tags are annotated, actually the last annotated tag is "v0.2",
whereas we are on "v1.3" tag now. This option is needed to get
something like v1.3-233-gbcc2bf0 instead of v0.2-1713-gbcc2bf0.
--dirty
The mark "-dirty" is appended if the source tree is locally
modified.
With this commit, the welcome string
NOTICE: BL1: v1.3(debug):bcc2bf0
will become like follows:
NOTICE: BL1: v1.3(debug):v1.3-233-gbcc2bf0-dirty
While we are here, let's add "2> /dev/null" as well to silently
ignore any error message from git. We should not assume that users
always work in a git repository; the ATF might be released in a
tarball form instead of a git repository. In such a case, the git
command will fail, then the ugly message "fatal: Not a git ..." will
be displayed during the build:
$ make CROSS_COMPILE=aarch64-linux-gnu-
fatal: Not a git repository (or any of the parent directories): .git

Makefile: Add ability to build dtb
This is a revamp of the original approach in:
https://github.com/ARM-software/arm-trusted-firmware/pull/747
Current build system has no means to automatically generate dtbs from
dts, instead, stores the dtbs in the fdts/ folder. While this makes
perfect sense for many reference platforms, this becomes a minor
breakage in development flow for newer platforms.
However, this can be solved by providing a rule for the dtbs while
building the ATF binaries by purely describing which dts sources we
need.
For example, with this change, we will now be able to describe the
dtbs we need for the platform in the corresponding platform.mk file:
FDT_SOURCES += fdts/abc.dts
This should be able to generate the abc.dtb appropriately.
Since device trees are specification of hardware, we don't tie the rule
to any specific BL, instead a generic rule is introduced.
Further, this approach allows us to generate appropriate dtbs which may be
need to be regenerated when a common dtsi gets updated, by just
restricting changes to the dtsi alone, instead of synchronizing all the
dtbs as well.
If dtc is not available in default paths, but is available in an
alternate location, it can be chosen by overriding the DTC variable
such as 'make DTC=~/dtc/dtc ....`
NOTE: dtbs are built only with the explicit make dtbs command. The rule
is only available if the platform defines a FDT_SOURCES variable.

fiptool: support --align option to add desired alignment to image offset
The current fiptool packs all the images without any padding between
them. So, the offset to each image has no alignment. This is not
efficient, for example, when the FIP is read from a block-oriented
device.
For example, (e)MMC is accessed by block-addressing. The block size
is 512 byte. So, the best case is each image is aligned by 512 byte
since the DMA engine can transfer the whole of the image to its load
address directly. The worst case is the offset does not have even
DMA-capable alignment (this is where we stand now). In this case,
we need to transfer every block to a bounce buffer, then do memcpy()
from the bounce buffer to our final destination. At least, this
should work with the abstraction by the block I/O layer, but the
CPU-intervention for the whole data transfer makes it really slow.
This commit adds a new option --align to the fiptool. This option,
if given, requests the tool to align each component in the FIP file
by the specified byte. Also, add a new Make option FIP_ALIGN for
easier access to this feature; users can give something like
FIP_ALIGN=512 from the command line, or add "FIP_ALIGN := 512" to
their platform.mk file.

Makefile: Add ability to build dtb
This is a revamp of the original approach in:
https://github.com/ARM-software/arm-trusted-firmware/pull/747
Current build system has no means to automatically generate dtbs from
dts, instead, stores the dtbs in the fdts/ folder. While this makes
perfect sense for many reference platforms, this becomes a minor
breakage in development flow for newer platforms.
However, this can be solved by providing a rule for the dtbs while
building the ATF binaries by purely describing which dts sources we
need.
For example, with this change, we will now be able to describe the
dtbs we need for the platform in the corresponding platform.mk file:
FDT_SOURCES += fdts/abc.dts
This should be able to generate the abc.dtb appropriately.
Since device trees are specification of hardware, we don't tie the rule
to any specific BL, instead a generic rule is introduced.
Further, this approach allows us to generate appropriate dtbs which may be
need to be regenerated when a common dtsi gets updated, by just
restricting changes to the dtsi alone, instead of synchronizing all the
dtbs as well.
If dtc is not available in default paths, but is available in an
alternate location, it can be chosen by overriding the DTC variable
such as 'make DTC=~/dtc/dtc ....`
NOTE: dtbs are built only with the explicit make dtbs command. The rule
is only available if the platform defines a FDT_SOURCES variable.
