2016-02-01Improve memory layout documentationJuan Castillo
This patch adds a brief explanation of the top/bottom load approach to the Firmware Design guide and how Trusted Firmware keeps track of the free memory at boot time. This will help platform developers to avoid unexpected results in the memory layout. Fixes ARM-software/tf-issues#319 Change-Id: I04be7e24c1f3b54d28cac29701c24bf51a5c00ad
2016-02-01Use tf_printf() for debug logs from xlat_tables.cSoby Mathew
The debug prints used to debug translation table setup in xlat_tables.c used the `printf()` standard library function instead of the stack optimized `tf_printf()` API. DEBUG_XLAT_TABLE option was used to enable debug logs within xlat_tables.c and it configured a much larger stack size for the platform in case it was enabled. This patch modifies these debug prints within xlat_tables.c to use tf_printf() and modifies the format specifiers to be compatible with tf_printf(). The debug prints are now enabled if the VERBOSE prints are enabled in Trusted Firmware via LOG_LEVEL build option. The much larger stack size definition when DEBUG_XLAT_TABLE is defined is no longer required and the platform ports are modified to remove this stack size definition.

2016-01-29Porting Guide: Clarify identity-mapping requirementSandrine Bailleux
The memory translation library in Trusted Firmware supports non-identity mappings for Physical to Virtual addresses since commit f984ce84ba. However, the porting guide hasn't been updated accordingly and still mandates the platform ports to use identity-mapped page tables for all addresses. This patch removes this out-dated information from the Porting Guide and clarifies in which circumstances non-identity mapping may safely be used. Fixes ARM-software/tf-issues#258 Change-Id: I84dab9f3cabfc43794951b1828bfecb13049f706
2016-01-29Clarify EL3 payload documentationSandrine Bailleux
This patch reworks the section about booting an EL3 payload in the User Guide: - Centralize all EL3 payload related information in the same section. - Mention the possibility to program the EL3 payload in flash memory and execute it in place. - Provide model parameters for both the Base and Foundation FVPs. - Provide some guidance to boot an EL3 payload on Juno.

ARM plat: add build option to unlock access to non-secure timer
2016-01-21Disable PL011 UART before configuring itJuan Castillo
The PL011 TRM (ARM DDI 0183G) specifies that the UART must be disabled before any of the control registers are programmed. The PL011 driver included in TF does not disable the UART, so the initialization in BL2 and BL31 is violating this requirement (and potentially in BL1 if the UART is enabled after reset). This patch modifies the initialization function in the PL011 console driver to disable the UART before programming the control registers. Register clobber list and documentation updated.

2016-01-20ARM plat: add build option to unlock access to non-secure timerJuan Castillo
Currently, Trusted Firmware on ARM platforms unlocks access to the timer frame registers that will be used by the Non-Secure world. This unlock operation should be done by the Non-Secure software itself, instead of relying on secure firmware settings. This patch adds a new ARM specific build option 'ARM_CONFIG_CNTACR' to unlock access to the timer frame by setting the corresponding bits in the CNTACR<N> register. The frame id <N> is defined by 'PLAT_ARM_NSTIMER_FRAME_ID'. Default value is true (unlock timer access). Documentation updated accordingly.

2016-01-13Add 'MAX_MMAP_REGIONS' and 'ADDR_SPACE_SIZE' to the Porting GuideJuan Castillo
This patch adds a brief description of 'MAX_MMAP_REGIONS' and 'ADDR_SPACE_SIZE' to the Porting Guide. These fields must be defined by the platform in order to use the translation table library. Change-Id: Ida366458fe2bc01979091a014dc38da0fae5991e
2016-01-13Rearrange fields in TF data structures to reduce paddingSoby Mathew
This patch rearranges fields of the `image_desc_t` & `auth_img_desc_t` data structures to reduce padding between the fields and thereby save memory. NOTE: Platform ports which anonymously initialize these structures should be aware of the rearrangement and do the required modification. Change-Id: I428b5429632797b31d5bd306174599c07e24c060

2016-01-07cert_create: update help messageJuan Castillo
The help message printed by the cert_create tool using the command line option -h (or --help) does not correctly list all the available command line options. This patch reworks the print_help() function to print the help messages in a data driven approach. For each command line option registered, an optional help message can be specified, which will be printed by print_help(). Help messages for the TBBR options (certificates, keys and images) are also provided. Fix a small bug in the short options string passed to getopt_long: the ':' was missing in the '-a' option (this option must take an argument). Fixes ARM-software/tf-issues#337 Change-Id: I9d08c2dfd349022808fcc884724f677eefdc1452

2016-01-05Apply TBBR naming convention to the fip_create optionsJuan Castillo
The fip_create tool specifies images in the command line using the ARM TF naming convention (--bl2, --bl31, etc), while the cert_create tool uses the TBBR convention (--tb-fw, --soc-fw, etc). This double convention is confusing and should be aligned. This patch updates the fip_create command line options to follow the TBBR naming convention. Usage examples in the User Guide have been also updated. NOTE: users that build the FIP by calling the fip_create tool directly from the command line must update the command line options in their scripts. Users that build the FIP by invoking the main ARM TF Makefile should not notice any difference. Change-Id: I84d602630a2585e558d927b50dfde4dd2112496f
2016-01-05Always build with '-pedantic'Sandrine Bailleux
By default ARM TF is built with the '-pedantic' compiler flag, which helps detecting violations of the C standard. However, the mbed TLS library and its associated authentication module in TF used to fail building with this compiler flag. As a workaround, the mbed TLS authentication module makefile used to set the 'DISABLE_PEDANTIC' TF build flag. The compiler errors flagged by '-pedantic' in the mbed TLS library have been fixed between versions 1.3.9 and 2.2.0 and the library now properly builds with this compiler flag. This patch fixes the remaining compiler errors in the mbed TLS authentication module in TF and unsets the 'DISABLE_PEDANTIC' TF build flag. This means that TF is now always built with '-pedantic'. In particular, this patch: * Removes the final semi-colon in REGISTER_COT() macro. This semi-colon was causing the following error message: drivers/auth/tbbr/tbbr_cot.c:544:23: error: ISO C does not allow extra ';' outside of a function [-Werror=pedantic] This has been fixed both in the mbed TLS authentication module as well as in the certificate generation tool. Note that the latter code didn't need fixing since it is not built with '-pedantic' but the change has been propagated for consistency. Also fixed the REGISTER_KEYS() and REGISTER_EXTENSIONS() macros, which were suffering from the same issue. * Fixes a pointer type. It was causing the following error message: drivers/auth/mbedtls/mbedtls_crypto.c: In function 'verify_hash': drivers/auth/mbedtls/mbedtls_crypto.c:177:42: error: pointer of type 'void *' used in arithmetic [-Werror=pointer-arith] Change-Id: I7b7a04ef711efd65e17b5be26990d1a0d940257d
2016-01-04Add ret to return from console_uninit() functionJimmy Huang
The 'ret' was missing in console_uninit() implementation, so the program doesn't return from console_uninit(). Instead, it keeps executing the following instructions which is not expected. Change-Id: I810684f37f61c41c6f95a3bb36914d0765da8571 Signed-off-by: Jimmy Huang <jimmy.huang@mediatek.com>
