rockchip: Clean up M0 Makefile, clarify float-abi
This patch shuffles the M0 Makefile flags around a bit trying to make
their purpose clearer and remove duplication. Since all three build
steps (compiling, assembling, linking) actually call GCC, remove the
misleading aliases $(AS) and $(LD) to avoid confusion that those tools
might be called directly. Split flags into a common group that has
meaning for all three steps and separate variables specific to each
step. Remove -nostartfiles which is a strict subset of -nostdlib.
Also add explicit parameters for -mfloat-abi=soft, -fomit-frame-pointer

built-in default and cause various problems if they resolve to

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

stdlib: Import timingsafe_bcmp() from FreeBSD
Some side-channel attacks involve an attacker inferring something from
the time taken for a memory compare operation to complete, for example
when comparing hashes during image authentication. To mitigate this,
timingsafe_bcmp() must be used for such operations instead of the
standard memcmp().
This function executes in constant time and so doesn't leak any timing
information to the caller.

*_SIZE + *_SIZE = *_END
The _LIMIT is generally defined by platform_def.h to indicate the
platform-dependent memory constraint. So, its typical usage is
ASSERT(. <= BL31_LIMIT, "BL31 image has exceeded its limit.")
in a linker script.
On the other hand, _END is used to indicate the end address of the
compiled image, i.e. we do not know it until the image is linked.
Here, all of these macros belong to the latter, so should be
suffixed with _END.

fiptool: fix add_image() and add_image_desc() implementation
The "make fip" shows the content of the generated FIP at the end of
the build. (This is shown by "fiptool info" command.)
Prior to commit
e0f083a09b29 ("fiptool: Prepare ground for expanding
the set of images at runtime"), the last part of the build log of
make CROSS_COMPILE=aarch64-linux-gnu- BL33=../u-boot/u-boot.bin fip
was like follows:
Trusted Boot Firmware BL2: offset=0xB0, size=0x4188, cmdline="--tb-fw"
EL3 Runtime Firmware BL31: offset=0x4238, size=0x6090, cmdline="--soc-fw"
Non-Trusted Firmware BL33: offset=0xA2C8, size=0x58B51, cmdline="--nt-fw"
With that commit, now it is displayed like follows:
Non-Trusted Firmware BL33: offset=0xB0, size=0x58B51, cmdline="--nt-fw"
EL3 Runtime Firmware BL31: offset=0x58C01, size=0x6090, cmdline="--soc-fw"
Trusted Boot Firmware BL2: offset=0x5EC91, size=0x4188, cmdline="--tb-fw"
You will notice two differences:
- the contents are displayed in BL33, BL31, BL2 order
- the offset values are wrong
The latter is more serious, and means "fiptool info" is broken.
Another interesting change is "fiptool update" every time reverses
the image order. For example, if you input FIP with BL2, BL31, BL33
in this order, the command will pack BL33, BL31, BL2 into FIP, in
this order. Of course, the order of components is not a big deal
except that users will have poor impression about this.
The root cause is in the implementation of add_image(); the
image_head points to the last added image. For example, if you call
add_image() for BL2, BL31, BL33 in this order, the resulted image
chain is:
image_head -> BL33 -> BL31 -> BL2
Then, they are processed from the image_head in "for" loops:
for (image = image_head; image != NULL; image = image->next) {
This means images are handled in Last-In First-Out manner.
Interestingly, "fiptool create" is still correct because
add_image_desc() also reverses the descriptor order and the command
works as before due to the double reverse.
The implementation of add_image() is efficient, but it made the
situation too complicated.
Let's make image_head point to the first added image. This will
add_image() inefficient because every call of add_image() follows
the ->next chain to get the tail. We can solve it by adopting a
nicer linked list structure, but I am not doing as far as that
because we handle only limited number of images anyway.
Do likewise for add_image_desc().

Currently, .d files are generated before any objects are built.
So, IS_ANYTHING_TO_BUILD flag is needed to avoid such processing for

There is a cleverer way; just create a .d file simultaneously when
the corresponding object is created. No need to have separate rules
for .d files.
This commit will also fix a bug; -D$(IMAGE) is defined for $(OBJ),
but not for $(PREREQUISITES). So, .d files are generated with
different macro sets from those for .o files, then wrong .d files
are generated.
For example, in lib/cpus/aarch64/cpu_helpers.S
#if IMAGE_BL31
#include <cpu_data.h>
#endif
<cpu_data.h> is parsed for the object when built for BL31, but the
