bb3d71b7ef crc16-ccitt: Rename file with CRC-16-CCITT implementation to crc16-ccitt.c
U-Boot CRC-16 implementation uses polynomial x^16 + x^12 + x^5 + 1 which is
not standard CRC-16 algorithm, but it is known as CRC-16-CCITT. Rename file
crc16.c to crc16-ccitt.c to reduce confusion.

e9e87ec47c tools: mkimage: Add Allwinner TOC0 support
Most Allwinner sunxi SoCs have separate boot ROMs in non-secure and
secure mode. The "non-secure" or "normal" boot ROM (NBROM) uses the
existing sunxi_egon image type. The secure boot ROM (SBROM) uses a
completely different image type, known as TOC0.

A TOC0 image is composed of a header and two or more items. One item
is the firmware binary. The others form a chain linking the firmware
signature to the root-of-trust public key (ROTPK), which has its hash
burned in the SoC's eFuses. Signatures are made using RSA-2048 + SHA256.

The pseudo-ASN.1 structure is manually assembled; this is done to work
around bugs/quirks in the boot ROM, which vary between SoCs. This TOC0
implementation has been verified to work with the A50, A64, H5, H6,
and H616 SBROMs, and it may work with other SoCs.

e8d26e8276 tools: kwboot: Add support for backspace key in mini terminal
Marvell BootROM recognize only '\b' byte as backspace. Use terminfo
for retrieving current backspace sequence and replace any occurrence of
backspace sequence by the '\b' byte.

Reading terminfo database is possible via tigetstr() function from system
library libtinfo.so.*. So link kwboot with -ltinfo.

Normally terminfo functions are in <term.h> system header file. But this
header file conflicts with U-Boot "termios_linux.h" header file. So declare
terminfo functions manually.

913866af6c tools: kwboot: Use separate thread for sending boot message pattern
After BootROM successfully detects boot message pattern on UART it waits
until host stop sending data on UART. For example Armada 385 BootROM
requires that host does not send anything on UART at least 24 ms. If host
is still sending something then BootROM waits (possibly infinitely).

BootROM successfully detects boot message pattern if it receives it in
small period of time after power on.

So to ensure that host put BootROM into UART boot mode, host must send
continuous stream of boot message pattern with a small gap (for A385 at
least 24 ms) after series of pattern. But this gap cannot be too often or
too long to ensure that it does not cover whole BootROM time window when it
is detecting for boot message pattern.

Therefore it is needed to do following steps in cycle without any delay:
1. send series of boot message pattern over UART
2. wait until kernel transmit all data
3. sleep small period of time

At the same time, host needs to monitor input queue, data received on the
UART and checking if it contains NAK byte by which BootROM informs that
xmodem transfer is ready.

But it is not possible to wait until kernel transmit all data on UART and
at the same time in the one process to also wait for input data. This is
limitation of POSIX tty API and also by linux kernel that it does not
provide asynchronous function for waiting until all data are transmitted.
There is only synchronous variant tcdrain().

So to correctly implement this handshake on systems with linux kernel, it
is needed to use tcdrain() in separate thread.

Implement sending of boot message pattern in one thread and reading of
reply in the main thread. Use pthread library for threads.

This change makes UART booting on Armada 385 more reliable. It is possible
to start kwboot and power on board after minute and kwboot correctly put
board into UART boot mode.

Old implementation without separate thread has an issue that it read just
one byte from UART input queue and then it send 128 message pattern to the
output queue. If some noise was on UART then kwboot was not able to read
BootROM response as its input queue was just overflowed and kwboot was
sending more data than receiving.

This change basically fixed above issue too.

d9612f4426 tools: mkeficapsule: allow for specifying GUID explicitly
The existing options, "--fit" and "--raw," are only used to put a proper
GUID in a capsule header, where GUID identifies a particular FMP (Firmware
Management Protocol) driver which then would handle the firmware binary in
a capsule. In fact, mkeficapsule does the exact same job in creating
a capsule file whatever the firmware binary type is.

To prepare for the future extension, the command syntax will be a bit
modified to allow users to specify arbitrary GUID for their own FMP driver.
OLD:
   [--fit <image> | --raw <image>] <capsule file>
NEW:
   [--fit | --raw | --guid <guid-string>] <image> <capsule file>

16abff246b tools: mkeficapsule: add firmware image signing
With this enhancement, mkeficapsule will be able to sign a capsule
file when it is created. A signature added will be used later
in the verification at FMP's SetImage() call.

To do that, we need specify additional command parameters:
  -monotonic-cout <count> : monotonic count
  -private-key <private key file> : private key file
  -certificate <certificate file> : certificate file
Only when all of those parameters are given, a signature will be added
to a capsule file.

Users are expected to maintain and increment the monotonic count at
every time of the update for each firmware image.

19a91f2464 Create a new boot/ directory
Quite a lot of the code in common/relates to booting and images. Before
adding more it seems like a good time to move the code into its own
directory.

Most files with 'boot' or 'image' in them are moved, except:

- autoboot.c which relates to U-Boot automatically running a script
- bootstage.c which relates to U-Boot timing

Drop the removal of boot* files from the output directory, since this
interfers with the symlinks created by tools and there does not appear
to be any such file from my brief testing.

ad906753c2 tools: kwbimage: Remove v1 kwbimage SPL padding to CONFIG_SYS_U_BOOT_OFFS bytes
This padding depends on board config file and therefore it makes the
mkimage binary tool board specific, which is not correct. One cannot use
mkimage tool built as a result for board A to generate images for board
B, even if both A and B are on the same platform.

This CONFIG_SYS_U_BOOT_OFFS padding was needed when kwbimage v1 contained
SPL code which loaded U-Boot proper based on CONFIG_SYS_U_BOOT_OFFS,
instead of reading correct offset from kwbimage header.

Now that SPL code parses kwbimage header and deterinate correct offset,
there is no need for this CONFIG_SYS_U_BOOT_OFFS padding anymore.

By removing it we also reduce the size of SPL code and therefore also
decrease the final size of v1 kwbimage. This means there is more space
for U-Boot proper binary.

cb9faa6f98 tools: Use a single target-independent config to enable OpenSSL
Host tool features, such as mkimage's ability to sign FIT images were
enabled or disabled based on the target configuration. However, this
misses the point of a target-agnostic host tool.

A target's ability to verify FIT signatures is independent of
mkimage's ability to create those signatures. In fact, u-boot's build
system doesn't sign images. The target code can be successfully built
without relying on any ability to sign such code.

Conversely, mkimage's ability to sign images does not require that
those images will only work on targets which support FIT verification.
Linking mkimage cryptographic features to target support for FIT
verification is misguided.

Without loss of generality, we can say that host features are and
should be independent of target features.

While we prefer that a host tool always supports the same feature set,
we recognize the following
  - some users prefer to build u-boot without a dependency on OpenSSL.
  - some distros prefer to ship mkimage without linking to OpenSSL

To allow these use cases, introduce a host-only Kconfig which is used
to select or deselect libcrypto support. Some mkimage features or some
host tools might not be available, but this shouldn't affect the
u-boot build.

I also considered setting the default of this config based on
FIT_SIGNATURE. While it would preserve the old behaviour it's also
contrary to the goals of this change. I decided to enable it by
default, so that the default build yields the most feature-complete
mkimage.

e89660f5ec common: Move host-only logic in image-sig.c to separate file
image-sig.c is used to map a hash or crypto algorithm name to a
handler of that algorithm. There is some similarity between the host

purpose of this change is to remove those ifdefs.

First, copy the file to a host-only version, and remove target
specific code. Although it looks like we are duplicating code,
subsequent patches will change the way target algorithms are searched.
Besides we are only duplicating three string to struct mapping
functions. This isn't something to fuss about.

in case of bmp_logo, the video_bmp driver is used for
drawing a bmp logo. This driver supports only "full"
bmp data. Adding a logo with the bmp_logo tool to
u-boot binary adds currently only real data and drops
the bmp header.

This patch adds now the full bmp data to the u-boot
binary, so video_bmp driver works with the logo embedded
into u-boot.

In U-Boot's case it holds u-boot-tpl.bin.

Add this tool, taken from coreboot, so that we can build bootable images

This tool itself has no tests. Some amount of coverage will be provided by

Since some of these sizes are not available to make, a new host tool
'spl_size_limit' is added that dumps the resulting maximum size for
an SPL binary to stdout. This tool is used in toplevel Makefile to
implement the size check on SPL binaries.

The motivation for this is to allow distributions to distribute all
possible tools in a generic way, avoiding the need of specific tools
building for each machine.

Especially on OpenEmbedded / Yocto Project ecosystem, it is very
common each BSP to end providing their specific tools when they need
to generate images for some SoC (e.g MX23 / MX28 in meta-freescale
case).

Using this, we can package the tools doing:

$: make tools-only_defconfig
$: make tools-only

51c2345bd2 Roll CRC16-CCITT into the hash infrastructure
The CRC16-CCITT checksum function is useful for space-constrained
applications (such as obtaining a checksum across a 2KBit or 4KBit
EEPROM) in boot applications. It has not been accessible from boot
scripts until now (due to not having a dedicated command and not being
supported by the hash infrstructure) limiting its applicability
outside of custom commands.

This adds the CRC16-CCITT (poly 0x1021, init 0x0) algorithm to the
list of available hashes and adds a new crc16_ccitt_wd_buf() to make
this possible.

72239fc85f vboot: Add FIT_SIGNATURE_MAX_SIZE protection
This adds a new config value FIT_SIGNATURE_MAX_SIZE, which controls the
max size of a FIT header's totalsize field. The field is checked before
signature checks are applied to protect from reading past the intended
FIT regions.

This field is not part of the vboot signature so it should be sanity
checked. If the field is corrupted then the structure or string region
reads may have unintended behavior, such as reading from device memory.
A default value of 256MB is set and intended to support most max storage
sizes.

6915dcf359 tools: zynqmpimage: Add bif support
The officially described way to generate boot.bin files for ZynqMP is to
describe the contents of the target binary using a file of the "bif"
format.  This file then links to other files that all get packed into a
bootable image.

This patch adds support to read such a .bif file and generate a respective
ZynqMP boot.bin file that can include the normal image and pmu files, but
also supports image partitions now. This makes it a handy replacement for
the proprietary "bootgen" utility that is currently used to generate
boot.bin files with FSBL.
