      Update makefile to build fiptool for Windows · 88a1cf1e
      Sami Mujawar authored 
      

Although support for building fiptool on a Windows host was present,
the binary was not built when the top level makefile was invoked.

This patch makes the necessary changes to the to support building of
fiptool on a Windows host PC from the main makefile.

      Fix fiptool packaging issue on windows · cb5c08b6
      Sami Mujawar authored 
      

Windows does not have a standard getopt implementation. To address
this an equivalent implementation has been provided in win_posix.c
However, the implementation has an issue with option processing as
described below.

Long option names may be abbreviated if the abbreviation is unique
or an exact match for some defined option.
Since some options can be substring of other options e.g. "scp-fw"
option is a substring of "scp-fwu-cfg", we need to identify if an
option is abbreviated and also check for uniqueness. Otherwise if
a user passes --scp-fw as an option, the "scp-fwu-cfg" option may
get selected, resulting in an incorrectly packaged FIP.

This issue has been be fixed by:
  - First searching for an exact match.
  - If exact match was not found search for a abbreviated match.
By doing this an incorrect option selection can be avoided.

      SPM: Alter sp_gen.mk entry depending on owner of partition · 1e7528ec
      Ruari Phipps authored 
      

With recently introduced dualroot CoT for SPs where they are owned
either by SiP or by Platform. SiP owned SPs index starts at SP_PKG1_ID
while Plat owned SPs index starts at SP_PKG5_ID.

This patch modifies SP makefile generator script to take CoT as an
argument and if it is "dualroot" then generates SP_PKG in order
mentioned above, otherwise generates it sequentially.

      cert_create: add Platform owned secure partitions support · 23d5f03a
      Manish Pandey authored 
      

Add support to generate a certificate named "plat-sp-cert" for Secure
Partitions(SP) owned by Platform.
Earlier a single certificate file "sip-sp-cert" was generated which
contained hash of all 8 SPs, with this change SPs are divided into
two categories viz "SiP owned" and "Plat owned" containing 4 SPs each.

Platform RoT key pair is used for signing.

      Use abspath to dereference $BUILD_BASE · 29214e95
      Grant Likely authored 
      

If the user tries to change BUILD_BASE to put the build products outside
the build tree the compile will fail due to hard coded assumptions that
$BUILD_BASE is a relative path. Fix by using $(abspath $(BUILD_BASE))
to rationalize to an absolute path every time and remove the relative
path assumptions.

This patch also adds documentation that BUILD_BASE can be specified by
the user.

      fiptool: return zero status on help and help <command> · 4e500525
      Leonardo Sandoval authored 
      

Querying the 'fiptool' for help or help <command> should return 0
return status (success) and not 1 (failure). In the other hand, if tool is
executed with any other command (not help) where command's parameters are
either missing or wrong, then the tool should return non-zero (failure). Now,
the 'usage' function caller is the one that passes the return status.

      cert_create: add SiP owned secure partitions support · 0792dd7d
      Manish Pandey authored 
      

Add support to generate certificate "sip-sp-cert" for Secure
Partitions(SP) owned by Silicon provider(SiP).
To avoid deviation from TBBR specification the support is only added for
dualroot CoT and not for TBBR CoT.

A single certificate file is generated containing hash of individual
packages. Maximum 8 secure partitions are supported.

Following new options added to cert_tool:
 --sip-sp-cert --> SiP owned Secure Partition Content Certificate
 --sp-pkg1 --> Secure Partition Package1 file
 --sp-pkg2
 .....
 --sp-pkg8

Trusted world key pair is used for signing.

Going forward, this feature can be extended for Platfrom owned
Partitions, if required.

      SPMD: generate and add Secure Partition blobs into FIP · ce2b1ec6
      Manish Pandey authored 
      

Till now TF-A allows limited number of external images to be made part
of FIP. With SPM coming along, there may exist multiple SP packages
which need to be inserted into FIP. To achieve this we need a more
scalable approach to feed SP packages to FIP.

This patch introduces changes in build system to generate and add SP
packages into FIP based on information provided by platform.
Platform provides information in form of JSON which contains layout
description of available Secure Partitions.
JSON parser script is invoked by build system early on and generates
a makefile which updates FIP, SPTOOL and FDT arguments which will be
used by build system later on for final packaging.

"SP_LAYOUT_FILE" passed as a build argument and can be outside of TF-A
tree. This option will be used only when SPD=spmd.

For each SP, generated makefile will have following entries
     - FDT_SOURCES	+=	sp1.dts
     - SPTOOL_ARGS	+= 	-i sp1.img:sp1.dtb -o sp1.pkg
     - FIP_ARGS		+=	--blob uuid=XXXX-XXX...,file=SP1.pkg

      SPM: modify sptool to generate individual SP blobs · 3977a825
      Manish Pandey authored 
      

Currently sptool generates a single blob containing all the Secure
Partitions, with latest SPM implementation, it is desirable to have
individual blobs for each Secure Partition. It allows to leverage
packaging and parsing of SP on existing FIP framework. It also allows
SP packages coming from different sources.

This patch modifies sptool so that it takes number of SP payload pairs
as input and generates number of SP blobs instead of a single blob.

Each SP blob can optionally have its own header containing offsets and
sizes of different payloads along with a SP magic number and version.
It is also associated in FIP with a UUID, provided by SP owner.

Usage example:
sptool -i sp1.bin:sp1.dtb -o sp1.pkg -i sp2.bin:sp2.dtb -o sp2.pkg ...

This representation is based on standard symbols present on the map
files as: __TEXT_START/END__, __RODATA_START/END__, __STACKS_START/END__

      Remove RSA PKCS#1 v1.5 support from cert_tool · 6a415a50
      Justin Chadwell authored 
      Support for PKCS#1 v1.5 was deprecated in SHA 1001202d and fully removed
in SHA fe199e3b

, however, cert_tool is still able to generate
certificates in that form. This patch fully removes the ability for
cert_tool to generate these certificates.

Additionally, this patch also fixes a bug where the issuing certificate
was a RSA and the issued certificate was EcDSA. In this case, the issued
certificate would be signed using PKCS#1 v1.5 instead of RSAPSS per
PKCS#1 v2.1, preventing TF-A from verifying the image signatures. Now
that PKCS#1 v1.5 support is removed, all certificates that are signed
with RSA now use the more modern padding scheme.

3072 and 4096. This is also modifiable by TFA using the build flag
KEY_SIZE.

      Standardise header guards across codebase · c3cf06f1
      Antonio Nino Diaz authored 
      

All identifiers, regardless of use, that start with two underscores are
reserved. This means they can't be used in header guards.

The style that this project is now to use the full name of the file in
capital letters followed by 'H'. For example, for a file called
"uart_example.h", the header guard is UART_EXAMPLE_H.

The exceptions are files that are imported from other projects:

- CryptoCell driver
- dt-bindings folders
- zlib headers
