  This is an optional hook that platforms can implement in order

  This is an optional hook that platforms can implement in order

If any of these interfaces are overridden by the platform, it is
recommended that all of them are.

By default `ENABLE_PSCI_STAT` is disabled.  If `ENABLE_PSCI_STAT`
is set but `ENABLE_PMF` is not set then an alternative PSCI stat
collection backend must be provided.  If both are set, then default
weak definitions of these functions are provided, using PMF to
calculate the residency.

NOTE: Previously, platforms did not have to explicitly set
`ENABLE_PMF` since this was automatically done by the top-level

Introduce unified API to zero memory

Introduce zeromem_dczva function on AArch64 that can handle unaligned
addresses and make use of DC ZVA instruction to zero a whole block at a
time. This zeroing takes place directly in the cache to speed it up
without doing external memory access.

Remove the zeromem16 function on AArch64 and replace it with an alias to
zeromem. This zeromem16 function is now deprecated.

Remove the 16-bytes alignment constraint on __BSS_START__ in
firmware-design.md as it is now not mandatory anymore (it used to comply
with zeromem16 requirements).

Change the 16-bytes alignment constraints in SP min's linker script to a
8-bytes alignment constraint as the AArch32 zeromem implementation is now
more efficient on 8-bytes aligned addresses.

Introduce zero_normalmem and zeromem helpers in platform agnostic header
that are implemented this way:
* AArch32:
* zero_normalmem: zero using usual data access
* zeromem: alias for zero_normalmem
* AArch64:
* zero_normalmem: zero normal memory  using DC ZVA instruction
                  (needs MMU enabled)
* zeromem: zero using usual data access

Usage guidelines: in most cases, zero_normalmem should be preferred.

There are 2 scenarios where zeromem (or memset) must be used instead:
* Code that must run with MMU disabled (which means all memory is
  considered device memory for data accesses).
* Code that fills device memory with null bytes.

Optionally, the following rule can be applied if performance is
important:
* Code zeroing small areas (few bytes) that are not secrets should use
  memset to take advantage of compiler optimizations.

  Note: Code zeroing security-related critical information should use
  zero_normalmem/zeromem instead of memset to avoid removal by
  compilers' optimizations in some cases or misbehaving versions of GCC.

    something like v1.3-233-gbcc2bf0 instead of v0.2-1713-gbcc2bf0.

  --dirty

With this commit, the welcome string

7 years agofiptool: support --align option to add desired alignment to image offset
Masahiro Yamada [Sun, 25 Dec 2016 04:52:22 +0000 (13:52 +0900)]
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.

fiptool: embed fip_toc_entry in struct image

The struct image has "uuid" and "size" to memorize the field values
they had in the TOC entry.  So, parse_fip() copies them from struct
fip_toc_entry to struct image, then pack_images() copies them back
to struct fip_toc_entry.

The next commit (support --align option) will require to save the
"offset" field as well.  This makes me realize that struct image
can embed struct fip_toc_entry.

This commit will allow the "flags" field to persevere the "update"
command.  At this moment, the "flags" is not used in a useful way.
(Yet, platforms can save their own parameters in the flags field.)
It makes sense to save it unless users explicitly replace the image.

Let's say you have an FIP with BL2, BL31, BL32, BL33.  If you update

with BL2, BL31, BL33, BL32, in this order.

It happens like this; remove_image() removes the old image from the
linked list, add_image() adds the new image at the tail of the list,
then images are packed in the new order.  Prior to that commit,
images were updated by replace_image(), but it was deleted by the

Use *_END instead of *_LIMIT for linker derived end addresses

The usage of _LIMIT seems odd here, so rename as follows:
  BL_CODE_LIMIT     --> BL_CODE_END
  BL_RO_DATA_LIMIT  --> BL_RO_DATA_END

  *_SIZE + *_MAX_SIZE = *_LIMIT
  *_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.

7 years agofiptool: fix add_image() and add_image_desc() implementation
Masahiro Yamada [Sat, 14 Jan 2017 14:22:02 +0000 (23:22 +0900)]
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().
